SYNOPSIS

10       #include <Xbae/Matrix.h>
11

DESCRIPTION

13       XbaeMatrix presents an editable array of string data to the user  in  a
14       scrollable  grid-like  format  similar  to a spreadsheet.  Non editable
15       pixmaps can also be displayed on the matrix.  The rows and  columns  of
16       the  Matrix may optionally be labeled.  Also, a number of fixed leading
17       or trailing rows or columns may be specified - these  behave  similarly
18       to  the  labels.  While XbaeMatrix looks and acts like a grid of XmText
19       widgets, it actually contains only one XmText.  This means that XbaeMa‐
20       trix widgets with hundreds or thousands of rows have much less overhead
21       than they would if they used an XmText for each cell.
22
23       Clicking on a cell with Button1 will edit the cell.  While  a  cell  is
24       being edited, Tab and Shift-Tab will edit the cell to the right or left
25       respectively.  The osfUp and osfDown keys will edit the cell  above  or
26       below.  Ctrl-Tab and Shift-Ctrl-Tab will traverse out of the Matrix and
27       into the next or previous tab groups.
28
29       The osfCancel key will cancel any edits made to a cell.   The  osfActi‐
30       vate key will commit any edits made to a cell and store them in the Ma‐
31       trix.  When traversing from another tab group into the Matrix, the  fo‐
32       cus  will  go to whichever cell is currently being edited.  If no cells
33       are being edited, then the upper left most visible non-fixed cell  will
34       be edited.
35
36       The  column sizes may be dynamically resized by pressing the Shift-But‐
37       ton2 combination when over a column boundary, similar to the  behaviour
38       of  some popular spreadsheets.  After a column has been resized in this
39       manner, the XbaeMatrix calls the callbacks on the  XmNresizeColumnCall‐
40       back callback list for post processing.
41
42       If  the  Matrix  is resized until it is too small to display all of the
43       cells in a given dimension, then it will display a ScrollBar  for  that
44       dimension.   The  horizontal ScrollBar will scroll the cells and column
45       labels, but not the row labels, fixed columns or  trailing  fixed  col‐
46       umns.  The vertical ScrollBar will scroll the cells and row labels, but
47       not the column labels, fixed rows or trailing fixed rows.
48
49       For the application programmer, XbaeMatrix provides callbacks to assist
50       in data validation.  The callbacks on the XmNmodifyVerifyCallback call‐
51       back list are called before text is inserted into, or deleted  from,  a
52       cell.   This  callback  list can be used to force user input to match a
53       certain pattern (e.g. a date format).  Similarly, the  XmNvalueChanged‐
54       Callback is called after text is inserted or deleted.
55
56       When  a cell is edited (by clicking on it or tabbing into it), the XmN‐
57       leaveCellCallback callbacks are called  for  the  previous  cell  being
58       edited,  if  any.   The application can verify the data entered in that
59       cell and disallow editing of the new cell if the data is  invalid.   If
60       the data was valid, then the XmNenterCellCallback callbacks for the new
61       cell are called.  These callbacks can be used to specify the  editabil‐
62       ity of the new cell.
63
64       The XmNtraverseCellCallback callbacks are also called when the user at‐
65       tempts to edit a new cell and when the matrix gains  or  looses  focus.
66       This  allows the application to override the default traversal behavior
67       of XbaeMatrix.
68
69       The XmNdefaultActionCallback is provided to allow a double click action
70       in a cell to perform some function.
71
72       Motif's Drag and Drop functionality can be achieved via the XmNprocess‐
73       DragCallback.
74
75       For large amounts of data, the overhead of assigning data to the widget
76       can  be  avoided using the XmNdrawCellCallback.  This callback also al‐
77       lows user defined pixmaps to be placed in a certain cell.   When  using
78       this callback, data for string fields can be written back to the appli‐
79       cation by using the XmNwriteCellCallback.

Classes

82       XbaeMatrix inherits behavior and resources from  the  Core,  Composite,
83       Constraint, and XmManager widget classes.
84       The class pointer is xbaeMatrixWidgetClass.
85       The class name is XbaeMatrix.
86

New Resources

88       The following table lists the new resources defined by XbaeMatrix.  The
89       codes in the ``Access'' column indicate whether the given resource  can
90       be  set  at  creation time (C), or set by using XtSetValues (S), or re‐
91       trieved by using XtGetValues (G).

316       XmNallowColumnResize
317            If True, allows the columns to be dynamically resized via the  Re‐
318            sizeColumns() action.  The default value is to allow column resiz‐
319            ing.
320
321       XmNallowRowResize
322            If True, allows the rows to be dynamically resized via the Resize‐
323            Rows() action.  The default value is to allow row resizing.
324
325       XmNaltRowCount
326            Specifies  the  number  of rows to use for each of the XmNevenRow‐
327            Background and XmNoddRowBackround colors. This resource is ignored
328            if XmNevenRowBackground and XmNoddRowBackround are not used.
329
330       XmNboldLabels
331            Overstrikes  the  row  and column labels to create a bold font ap‐
332            pearance when True.
333
334       XmNbuttonLabels
335            When set to True, the labels will be drawn with  a  shadow  around
336            them similar to an XmPushButton widget. A ButtonPress event gener‐
337            ated on the labels, when XmNbuttonLabels is True  will  cause  the
338            label to reverse the shadow and take on a pushed in appearance.  A
339            ButtonRelease event on the same label will invoke callbacks on the
340            XmNlabelActivateCallback, list. The default value is False.
341
342       XmNbuttonLabelBackground
343            Specifies a Pixel value in which to draw the XmNbuttonLabels.
344
345       XmNcalcCursorPosition
346            If set to True, the insertion position on the text field is calcu‐
347            lated with respect to where the pointer was clicked in  the  cell.
348            The  default value is False.  The insertion position will be over‐
349            ridden if the position member of  the  XbaeEnterCellCallbackStruct
350            is set to a valid position.
351
352       XmNcellBackgrounds
353            Points  to  an  array of pointers to rows. Each row is an array of
354            Pixel values, one for each column in that row. This data structure
355            is the same as that for XmNcells, except each entry is a Pixel in‐
356            stead of a String.  The background of a cell will be drawn in  the
357            color  specified  for  that  cell.  If XmNcellBackgrounds is NULL,
358            backgrounds will be drawn using the color  specified  by  XmNback‐
359            ground.  This resource is copied.  XmNcellBackgrounds may be spec‐
360            ified in a resource file but due to the two dimensional nature  of
361            the  XbaeMatrix  widget,  it must be done by terminating each line
362            with a \n character.  If the XbaeMatrix widget had XmNrows set  to
363            5  and  XmNcolumns set to 5, XmNcellBackgrounds would be specified
364            as:
365
366
367
368            *mw.cellBackgrounds:   blue, white, blue, white, blue\n\
369                                   white, blue, white, blue, white\n\
370                                   blue, white, blue, white, blue\n\
371                                   white, blue, white, blue, white\n\
372                                   blue, white, blue, white, blue\n
373             Care must be taken when specifying these  values  in  a  resource
374            file as an incorrect format can produce undesirable results.
375
376       XmNcellHighlightThickness
377            Specifies  the  XmNhighlightThickness  resource of the XmText cell
378            edit widget. This resource is also used to  compute  the  size  of
379            each  cell.  See  the  description of XmNhighlightThickness in Xm‐
380            Text(3X).
381
382       XmNcellMarginHeight
383            Specifies the XmNmarginHeight resource of the XmText widget.  This
384            resource  is  also  used to compute the size of each cell. See the
385            description of XmNmarginHeight in XmText(3X).
386
387       XmNcellMarginWidth
388            Specifies the XmNmarginWidth resource of the XmText cell edit wid‐
389            get.  This resource is also used to compute the size of each cell.
390            See the description of XmNmarginWidth in XmText(3X).
391
392       XmNcellShadowThickness
393            Specifies the XmNshadowThickness resource of the XmText cell  edit
394            widget.  This  resource  is  also used to compute the size of each
395            cell. See the description of XmNshadowThickness in XmText(3X).
396
397       XmNcellShadowType
398            Specifies the type of shadow drawn  around  each  cell.   Possible
399            values   for   this   resource   are   XmSHADOW_OUT,  XmSHADOW_IN,
400            XmSHADOW_ETCHED_OUT, and XmSHADOW_ETCHED_IN.  The  default  shadow
401            type is XmSHADOW_OUT.
402
403       XmNcellShadowTypes
404            Specifies  on a per cell basis, the XmNcellShadowType.  Values for
405            the resource are the same as for XmNcellShadowType.  This resource
406            is copied.
407
408       XmNcellUserData
409            Points to an array of pointers to individual user defined data ar‐
410            eas associated with each cell.  The data should be set using Xbae‐
411            MatrixSetCellUserData() and retrieved using XbaeMatrixGetCellUser‐
412            Data().  This resource cannot be specified in a resource file  and
413            is copied.
414
415       XmNcells
416            Points  to  an  array of pointers to rows. Each row is an array of
417            String, one for each column in that row. For  example,  the  cells
418            for a 2x3 Matrix could be set up as follows:
419
420
421
422            String rows[2][3] =
423            {
424                 "00",   "01",   "02",
425                 "10",   "11",   "12"
426            };
427
428                String *cells[2];
429                cells[0] = &rows[0][0];
430                cells[1] = &rows[1][0];
431
432
433            Now  cells  could be used as the XmNcells resource. If XmNcells is
434            NULL, XbaeMatrix will not generate  an  internal  table  of  empty
435            Strings. This implies that if XmNcells is NULL, no cells have been
436            set.  This resource is copied.  See the discussion in XmNcellBack‐
437            grounds for how to specify XmNcells in a resource file.
438
439       XmNclipWindow
440            The  widget  ID of the clip window.  The clip window is the widget
441            that contains the non-fixed region of cells. This resource can not
442            be set to a new value.
443
444       XmNcolors
445            Points  to  an  array of pointers to rows. Each row is an array of
446            Pixel values, one for each column in that row. This data structure
447            is the same as that for XmNcells, except each entry is a Pixel in‐
448            stead of a String.  The text in a cell will be drawn in the  color
449            specified for that cell.  If XmNcolors is NULL, text will be drawn
450            using the color specified  by  XmNforeground.   This  resource  is
451            copied.  See the discussion in XmNcellBackgrounds for how to spec‐
452            ify XmNcolors in a resource file.
453
454       XmNcolumnAlignments
455            Points to an array of alignments (unsigned  char),  one  for  each
456            column.   Each  element  can be one of XmALIGNMENT_BEGINNING, XmA‐
457            LIGNMENT_CENTER or XmALIGNMENT_END.  This specifies the  alignment
458            of  the  text  or  pixmap in each cell of that column. See the de‐
459            scription of XmNalignment for XmLabel(3X).  If XmNcolumnAlignments
460            is  NULL, each column will default to XmALIGNMENT_BEGINNING.  This
461            resource is copied.
462
463       XmNcolumnButtonLabels
464            An array of Booleans that tells the XbaeMatrix which column labels
465            should  be  drawn as a button.  Each Boolean can be specified as a
466            Boolean string or integer. In order to use this resource,  XmNbut‐
467            tonLabels should be set to False.
468
469       XmNcolumnLabelAlignments
470            Points  to  an  array  of alignments (unsigned char), one for each
471            column label. Each element can be  one  of  XmALIGNMENT_BEGINNING,
472            XmALIGNMENT_CENTER  or XmALIGNMENT_END.  This specifies the align‐
473            ment of the text of each column label. See the description of  Xm‐
474            Nalignment  for XmLabel(3X).  If XmNcolumnLabelAlignments is NULL,
475            each column label will default to XmALIGNMENT_BEGINNING.  This re‐
476            source is copied.
477
478       XmNcolumnLabelColor
479            Specifies a Pixel value in which to draw the XmNcolumnLabels.
480
481       XmNcolumnLabels
482            Points  to an array of Strings to be drawn above each column. Each
483            String may have embedded newline characters, in which case the la‐
484            bel  will be drawn on multiple lines. If there is a XmNxmColumnLa‐
485            bels defined for this coluumn it will be displayed in place of the
486            XmNcolumnLabels.   If  XmNcolumnLabels  and  XmNxmColumnLabels are
487            NULL, no labels will be drawn. This resource is copied.
488
489       XmNcolumnMaxLengths
490            Points to an array of int, one for each column. These specify  the
491            maximum  length  of  a String which can be entered in the cells in
492            that column. See the description of  the  XmText(3X)  XmNmaxLength
493            resource.  If XmNcolumnMaxLengths is NULL or an element of the ar‐
494            ray is equal to 0, then the corresponding  width  from  XmNcolumn‐
495            Widths is used. This resource is copied.
496
497       XmNcolumnShadowTypes
498            Specifies  on  a  per column basis, the XmNcellShadowType.  Values
499            for the resource are the same as for XmNcellShadowType.  This  re‐
500            source is copied.
501
502       XmNcolumnUserData
503            Points  to  a  user defined data area associated with a particular
504            column.  The data should  be  set  using  XbaeMatrixSetColumnUser‐
505            Data()  and  retrieved  using XbaeMatrixGetColumnUserData().  This
506            resource cannot be specified in a resource file.
507
508       XmNcolumnWidthInPixels
509            Specifies wether the elements of XmNcolumnWidths are  measured  in
510            pixels or characters.
511
512       XmNcolumnWidths
513            Points  to  an  array of short, one for each column. These specify
514            the visible width of the cells in each column. See the description
515            of the XmText(3X) XmNcolumns resource.  This resource is copied.
516
517       XmNcolumns
518            Specifies  the  total number of columns of cells.  XmNcolumns must
519            be at least one. If the number of columns is changed via XtSetVal‐
520            ues, then XmNcolumnMaxLengths must change or be NULL, XmNcolumnLa‐
521            bels must change or be NULL, XmNcolumnAlignments must change or be
522            NULL  and  XmNcolumnLabelAlignments  must  change or be NULL.  The
523            preferred way to dynamically change the number of  columns  is  to
524            use XbaeMatrixAddColumns() or XbaeMatrixDeleteColumns().
525
526       XmNdefaultActionCallback
527            Specifies a list of callbacks to be called when a double click oc‐
528            curs in a cell.  A pointer to an  XbaeMatrixDefaultActionCallback‐
529            Struct is passed to the callbacks. Events are reported to the cell
530            in which the double click occurs regardless of whether  or  not  a
531            callback  exists.   This callback is called by the DefaultAction()
532            action and is NULL by default.   The  XmNdefaultActionCallback  is
533            ideal  for popping up a dialog or other window when a double click
534            occurs.
535
536       XmNdoubleClickInterval
537            Specifies the amount of time between mouse  clicks  before  it  is
538            considered  a  double  click.  A double click is defined to be the
539            time between the realease of the mouse button and subsequent press
540            in  the  same  cell.  The default value is inherited from the dis‐
541            play.
542
543       XmNdrawCellCallback
544            Specifies a list of callbacks to be called when a cell needs to be
545            drawn.  A pointer to an XbaeMatrixDrawCellCallbackStruct is passed
546            to the callbacks. The application can specify what  to  put  in  a
547            cell  by modifying the callback struct's data fields. When the ap‐
548            plication callback returns to the widget code, the type field will
549            determine  what  the  widget  draws on the screen. If the value is
550            XbaeString, then the regular string drawing function for the  wid‐
551            get  will  be called with the value the applicaton assigned to the
552            string field in the struct. If the  value  is  XbaeStringFree  the
553            widget  also calls XtFree on the string when it is not needed any‐
554            more. Else, if the value is XbaePixmap,  the  widget  will  do  an
555            XCopyPlane(),  in  the  case  of  a single plane bitmap, or XCopy‐
556            Area(), in the case of a color pixmap.  The width  and  height  of
557            cell  is  passed in the struct so the application can know how big
558            to make the pixmap. In no case will a copy of the  string  or  the
559            pixmap value be made. The widget also uses the XmNcolumnAlignments
560            resource to determine the horizontal alignment of the Pixmap.   To
561            have  an  editable  array  of data when the XmNdrawCellCallback is
562            used and the cell is of type XbaeString or XbaeStringFree, use the
563            XmNwriteCellCallback.
564
565       XmNenterCellCallback
566            Specifies  a  list  of callbacks to be called immediately before a
567            cell is to be edited. This callback list is called  by  the  Edit‐
568            Cell()  action.  A pointer to an XbaeMatrixEnterCellCallbackStruct
569            is passed to the callbacks. The application can  specify  the  ed‐
570            itability  of  specific  cells using this callback list as well as
571            specifying configuration options for the XmText.
572
573       XmNevenRowBackground
574            Specifies a background cell Pixel value to use on even rows.  This
575            allows  the matrix to look like computer paper. For wider bands of
576            color, increase the size of XmNaltRowCount.
577
578       XmNfill
579            If True, controls whether the matrix should fill all of its avail‐
580            able  space  when  additional  space if available, or if it should
581            simply size itself as large as necessary, regardless of any  addi‐
582            tonal available space.
583
584       XmNhorzFill
585            If  True,  controls  whether the matrix should highlight available
586            space on the right of  the  selected  cell(s)  when  the  selected
587            cell(s) are in the last column of the matrix.
588
589       XmNvertFill
590            If  True,  controls  whether the matrix should highlight available
591            space below the selected cell(s) when the selected cell(s) are  in
592            the last row of the Matrix.
593
594       XmNfixedColumns
595            Specifies  the  number  of leading columns (starting from the left
596            column) which should not be  horizontally  scrollable.   XmNfixed‐
597            Columns  must  be  less  than  XmNcolumns-XmNtrailingFixedColumns.
598            Cells in fixed columns are not editable  unless  XmNtraverseFixed‐
599            Cells is set to True.
600
601       XmNfixedRows
602            Specifies  the  number of leading rows (starting from the top row)
603            which should not be vertically scrollable.  XmNfixedRows  must  be
604            less  than  XmNrows-XmNtrailingFixedRows.  Cells in fixed rows are
605            not editable unless XmNtraverseFixedCells is set to True.
606
607       XmNfontList
608            If the value of XmNrenderTable is NULL this resource specifies the
609            font  list  to be used for the text displayed in the cells and the
610            XmText cell edit widget. See XmFontListCreate(3X) to create a font
611            list.  This resource is copied.  The preferred way of specifying a
612            font for the table is in a resource file.
613
614            When drawing a cell, the matrix uses the first entry with the  tag
615            XmFONTLIST_DEFAULT_TAG  if  no  tag has been set on the cell using
616            XbaeMatrixSetCellTag.  If a tag has been set on the cell the first
617            entry with a matching tag is used.
618
619       XmNgridLineColor
620            Specifies the color in which the grid line should be drawn if XmN‐
621            gridType  is  set  to  XmGRID_CELL_LINE,  XmGRID_ROW_LINE  or  Xm‐
622            GRID_COLUMN_LINE.  The default is that of XmNforeground.
623
624       XmNgridType
625            Sets  the  way the matrix grid is drawn.  The grid types available
626            include  XmGRID_NONE,  XmGRID_CELL_LINE,  XmGRID_CELL_SHADOW,  Xm‐
627            GRID_ROW_LINE,   XmGRID_ROW_SHADOW,   XmGRID_COLUMN_LINE  and  Xm‐
628            GRID_COLUMN_SHADOW.  All of the grid types vary the way the shadow
629            or   line   is   drawn  around  the  cell.   XmGRID_ROW_LINE,  Xm‐
630            GRID_ROW_SHADOW, XmGRID_COLUMN_LINE, and XmGRID_COLUMN_SHADOW only
631            draw  a  border around the rows and columns, giving a more tabular
632            rather  than  spreadsheet   appearance.   The   default   is   Xm‐
633            GRID_CELL_LINE which draws a solid line around the cells.
634
635       XmNhighlightedCells
636            Points  to  an  array of pointers to rows. Each row is an array of
637            unsigned char values, one for each column in that row.  This  data
638            structure  is  the same as that for XmNcells, except each entry is
639            an unsigned char instead of a String. Each entry in the array will
640            have  a  value  that is either HighlightNone, HighlightCell, High‐
641            lightRow, HighlightColumn, HighlightOther or  the  bitwise  OR  of
642            those values, depending on the value of XmNgridType and which call
643            was used to highlight the cell.  A cell will  be  drawn  as  high‐
644            lighted if the corresponding unsigned char does not have the value
645            HighlightNone.  If XmNhighlightedCells is NULL, XbaeMatrix then no
646            cells  have been highlighted.  This resource is copied, and cannot
647            be specified in a resource file.
648
649       XmNhorizontalScrollBar
650            The widget ID of the horizontal XmScrollBar.  This resource exists
651            only  for those applications that need to tie another scrollbar to
652            the matrix's for synchronized scrolling.  This resource can not be
653            set to a new value.
654
655       XmNhorizontalScrollBarDisplayPolicy
656            Determines  when  to display a horizontal scrollbar in the matrix.
657            Possible values are XmDISPLAY_NONE, which makes the  matrix  never
658            display the scrollbar, XmDISPLAY_AS_NEEDED, which makes the matrix
659            display the scrollbar when the  list  is  too  large,  and  XmDIS‐
660            PLAY_STATIC, which makes the matrix always display the scrollbar.
661
662       XmNlabelFont
663            If the value of XmNrenderTable is NULL this resource specifies the
664            font list to be used for the text displayed in row and column  la‐
665            bels.  If  XmNlabelFont is not specified, the value of XmNfontList
666            is used for the label fonts. See XmFontListCreate(3X) to create  a
667            font list. This resource is copied.  The preferred way of specify‐
668            ing a font for the labels is in a resource file.
669
670            When drawing a label, the matrix uses the first entry with the tag
671            XmFONTLIST_DEFAULT_TAG.
672
673
674       XmNlabelActivateCallback
675            Specifies  a  list  of callbacks to be called after a button label
676            has been pressed.  A pointer  to  an  XbaeMatrixLabelActivateCall‐
677            backStruct is passed to the callbacks on this list.
678
679       XmNleaveCellCallback
680            Specifies  a  list  of  callbacks to be called immediately after a
681            cell has been edited. This callback list is called  by  the  Edit‐
682            Cell()  and CommitEdit() actions. A pointer to an XbaeMatrixLeave‐
683            CellCallbackStruct is passed to the callbacks. The application can
684            perform cell specific data checks using this callback list.
685
686       XmNleftColumn
687            Allows the programmer to specify the first non fixed column to ap‐
688            pear on the leftmost side of the matrix.   This  resource  compli‐
689            ments  the XmNtopRow resource. See the discussion of XmNtopRow for
690            more details.
691
692       XmNmodifyVerifyCallback
693            Specifies a list of callbacks to be called before text is  deleted
694            from or inserted into the XmText cell edit widget. A pointer to an
695            XbaeMatrixModifyVerifyCallbackStruct is passed to  the  callbacks.
696            See  the description of the XmText(3X) XmNmodifyVerifyCallback re‐
697            source.
698
699       XmNmultiLineCell
700            is a boolean (default False) which specifies  whether  the  matrix
701            displays more than one line of text in a cell, when appropriate.
702
703       XmNnonFixedDetachedLeft
704            Indicated  that  empty  space  should be displayed after the fixed
705            rows. This resource only has effect when XmNfill is true and  XmN‐
706            fixedRows is greater than zero.
707
708       XmNnonFixedDetachedTop
709            Indicated  that  empty  space  should be displayed after the fixed
710            columns. This resource only has effect when XmNfill  is  true  and
711            XmNfixedColumns is greater than zero.
712
713       XmNoddRowBackground
714            Specifies  a background cell color to use on odd rows. This allows
715            the matrix to look like computer paper. For wider bands of  color,
716            increase the size of XmNaltRowCount.
717
718       XmNprocessDragCallback
719            Specifies  a list of callbacks to be called from the ProcessDrag()
720            action A pointer to an XbaeMatrixProcessDragCallbackStruct will be
721            passed  to  the  callbacks.  The application can use this callback
722            list to perform particular processing during a drag.
723
724       XmNrenderTable
725            Specifies the render table used to derive a font set or a font  to
726            draw  the text displayed in the cells, the XmText cell edit widget
727            and the labels.
728
729            When drawing a cell, the matrix uses the first entry with the  tag
730            _MOTIF_DEFAULT_LOCALE  if  no  tag  has been set on the cell using
731            XbaeMatrixSetCellTag.  If a tag has been set on the cell the first
732            entry with a matching tag is used.
733
734            When drawing a label, the matrix uses the first entry with the tag
735            "labels". If there is no such entry the first entry with  the  tag
736            _MOTIF_DEFAULT_LOCALE is used.
737
738
739       XmNresizeCallback
740            Specifies  a list of callbacks to be called when the matrix is re‐
741            sized.
742
743       XmNresizeColumnCallback
744            Specifies a list of callbacks to be called when a column is dynam‐
745            ically resized by the user.
746
747       XmNreverseSelect
748            Overrides  the  default XmNselectedForeground and XmNselectedBack‐
749            ground and draws a selected cell in the colours specified by  XmN‐
750            cellBackgrounds  and  XmNcolors for the particular cell.  If these
751            values are not set then the default colours will be used.
752
753       XmNrowButtonLabels
754            An array of Booleans that tells the XbaeMatrix  which  row  labels
755            should  be  drawn as a button.  Each Boolean can be specified as a
756            Boolean string or integer. In order to use this resource,  XmNbut‐
757            tonLabels should be set to False.
758
759       XmNrowLabelAlignment
760            Specifies  the  alignment of the row labels. It can be one of XmA‐
761            LIGNMENT_BEGINNING, XmALIGNMENT_CENTER  or  XmALIGNMENT_END.   See
762            the   description  of  XmNalignment  for  XmLabel(3X).   XmNrowLa‐
763            belAlignment defaults to XmALIGNMENT_END.
764
765       XmNrowLabelColor
766            Specifies a Pixel value in which to draw the XmNrowLabels.
767
768       XmNrowLabelWidth
769            Specifies the width of the row labels.  XmNrowLabelWidth  defaults
770            to the width of the longest row label.
771
772       XmNrowLabels
773            Points to an array of Strings to be drawn to the left of each row.
774            Each String may have embedded newline characters,  in  which  case
775            the  label  will  be drawn on multiple lines. If there is a XmNxm‐
776            RowLabels defined for this row it will be displayed  in  place  of
777            the XmNrowLabels.  If XmNrowLabels and XmNxmRowLabels are NULL, no
778            labels will be drawn. This resource is copied.
779
780       XmNrowHeightInPixels
781            Specifies wether the elements of  XmNrowHeights  are  measured  in
782            pixels or lines.
783
784       XmNrowHeights
785            Points  to  an array of short, one for each row. These specify the
786            visible height of the cells in each row. This resource is copied.
787
788       XmNrowShadowTypes
789            Specifies on a per row basis, the XmNcellShadowType.   Values  for
790            the resource are the same as for XmNcellShadowType.  This resource
791            is copied.
792
793       XmNrowUserData
794            Points to a user defined data area associated  with  a  particular
795            row.   The data should be set using XbaeMatrixSetRowUserData() and
796            retrieved using XbaeMatrixGetRowUserData().  This resource  cannot
797            be specified in a resource file.
798
799       XmNrows
800            Specifies  the  total number of rows of cells.  XmNrows must be at
801            least one. If the number of rows is changed via XtSetValues,  then
802            XmNrowLabels must change or be NULL.  The preferred way to dynami‐
803            cally change the number of rows is to use  XbaeMatrixAddRows()  or
804            XbaeMatrixDeleteRows().
805
806       XmNscrollBarPlacement
807            Determines where the scrollbars will be drawn.  See the discussion
808            of XmNscrollBarPlacement in  XmScrolledWindow(3)  for  a  complete
809            discussion on this resource.

812            Specifies  a  list of callbacks to be called from the SelectCell()
813            action.  A pointer to an  XbaeMatrixSelectCellCallbackStruct  will
814            be  passed to the callbacks. The application can use this callback
815            list to perform selection/deselection of cells using the  provided
816            widget methods.
817
818       XmNselectScrollVisible
819            Specifies whether the matrix will scroll to make the selected cell
820            visible.  This flag is only checked when cells are  selected  pro‐
821            grammatically,  as when the user selects a cell with the mouse, it
822            will already be visible.
823
824       XmNselectedBackground
825            Allows the background of selected cells in XmNselectedCells to  be
826            specified.
827
828       XmNselectedCells
829            Points  to  an  array of pointers to rows. Each row is an array of
830            Boolean values, one for each column in that row. This data  struc‐
831            ture  is  the  same  as  that for XmNcells, except each entry is a
832            Boolean instead of a String. A cell will be drawn as  selected  if
833            the  corresponding  Boolean  is True. If XmNselectedCells is NULL,
834            then no cells have been selected.  This resource  is  copied.   It
835            cannot be specified in a resource file.
836
837       XmNselectedForeground
838            Allows  the foreground of selected cells in XmNselectedCells to be
839            specified.
840
841       XmNshadowType
842            Specifies the type of shadow drawn around the border  of  the  ma‐
843            trix.    Possible  values  for  this  resource  are  XmSHADOW_OUT,
844            XmSHADOW_IN, XmSHADOW_ETCHED_OUT, and XmSHADOW_ETCHED_IN.  The de‐
845            fault shadow type is XmSHADOW_OUT.
846
847       XmNshowArrows
848            Specifies  whether  arrows should be drawn when data in a cell has
849            been obscured due to the value of XmNcolumnWidths.
850
851       XmNspace
852            Specifies the distance that separates the ScrollBars from the cell
853            grid. The default value is 4 pixels.
854
855       XmNtextBackground
856            Specifies  the background of the XmText cell edit widget. This can
857            be used to make the XmText stand out against a  uniformly  colored
858            matrix.
859
860       XmNtextBackgroundIsCell
861            Specifies  if  the  background  of the XmText cell edit widget de‐
862            faults to the core background of the matrix or the  background  of
863            the  cell  being edited when XmNtextBackground has the value XmUN‐
864            SPECIFIED_PIXEL.
865
866       XmNtextField
867            The widget ID of the XmText.  This resource cannot be set to a new
868            value.
869
870       XmNtextShadowThickness
871            Specifies  the  XmNshadowThickness of the XmText.  Interesting ef‐
872            fects can be achieved by setting the XmNcellHighlightThickness  to
873            0 and replacing the highlight with an indented shadow.
874
875       XmNtextTranslations
876            Specifies  the  XmNtranslations  resource  of the XmText cell edit
877            widget. See the description of XmNtranslations in XmText(3X).
878
879       XmNtopRow
880            Specifies the row which should be displayed at the top of the non-
881            fixed  rows.   XmNtopRow  is  specified relative to the first non-
882            fixed row, so (XmNfixedRows + XmNtopRow) is the actual row  number
883            which  will be moved to the top. If (XmNtopRow > (XmNrows - (<num‐
884            ber of rows visible> + XmNfixedRows), then the  actual  row  which
885            will be moved to the top is (XmNrows - (<number of rows visible> +
886            XmNfixedRows).
887
888       XmNtrackCellCallback
889            specifies a list of callbacks to be called when the mouse  pointer
890            is being moved.
891
892       XmNtrailingAttachedBottom
893            Indicated  that  any trailing fixed rows should be attached to the
894            bottom of the matrix. This resource only has effect  when  XmNfill
895            is true and XmNtrailingFixedRows is greater than zero.
896
897       XmNtrailingAttachedRight
898            Indicated  that  any  trailing fixed columns should be attached to
899            the right of the matrix. This resource only has effect  when  XmN‐
900            fill is true and XmNtrailingFixedColumns is greater than zero.
901
902       XmNtrailingFixedColumns
903            Specifies  the number of trailing columns (starting from the right
904            column) which should not be horizontally scrollable.  XmNtrailing‐
905            FixedColumns  must be less than XmNcolumns-XmNfixedColumns.  Cells
906            in trailing fixed columns are  not  editable  unless  XmNtraverse‐
907            FixedCells is set to True.
908
909       XmNtrailingFixedRows
910            Specifies  the  number  of trailing rows (starting from the bottom
911            row) which should  not  be  vertically  scrollable.   XmNtrailing‐
912            FixedRows must be less than XmNrows-XmNfixedRows.  Cells in trail‐
913            ing fixed rows are not editable  unless  XmNtraverseFixedCells  is
914            set to True.
915
916       XmNtraverseCellCallback
917            Specifies  a  list  of callbacks to be called before a new cell is
918            edited.  These callbacks are called by the EditCell()  action  and
919            when  XbaeMatrix receives or looses focus. A pointer to an XbaeMa‐
920            trixTraverseCellCallbackStruct is passed to the callbacks. The ap‐
921            plication  can  specify  the  next cell which should be edited via
922            this callback list, thereby performing custom traversal.
923
924       XmNtraverseFixedCells
925            If True, this resource  allows  fixed  cells  and  columns  to  be
926            edited.   The  default is to not allow fixed rows or columns to be
927            edited.
928
929       XmNuseXbaeInput
930            This boolean value determines whether  to  use  XbaeInput  or  Xm‐
931            TextField as the widget used for editing cells.  Default is not to
932            use XbaeInput.
933
934       XmNvalueChangedCallback
935            Specifies a list of callbacks to be called after text  is  deleted
936            from or inserted into the XmText cell edit widget. A pointer to an
937            XbaeMatrixValueChangedCallbackStruct is passed to  the  callbacks.
938            See  the description of the XmText(3X) XmNvalueChangedCallback re‐
939            source.
940
941       XmNverticalScrollBar
942            The widget ID of the vertical XmScrollBar.  This  resource  exists
943            only  for those applications that need to tie another scrollbar to
944            the matrix's for synchronized scrolling.  This resource can not be
945            set to a new value.
946
947       XmNverticalScrollBarDisplayPolicy
948            Determines  when  to display a horizontal scrollbar in the matrix.
949            Possible values and their effects  are  listed  under  XmNhorizon‐
950            talScrollBarDisplayPolicy.
951
952       XmNvisibleColumns
953            Specifies the number of non-fixed columns which should be visible.
954            The widget will request a size which will allow  XmNvisibleColumns
955            columns  to  be  displayed.   The  programmer should take into al‐
956            lowance any XmNfixedColumns that are specified.  This feature  be‐
957            comes  even more apparent if the number of XmNfixedColumns changes
958            at runtime as the value may need to be adjusted to avoid  a  warn‐
959            ing.
960
961       XmNvisibleRows
962            Specifies  the  number  of rows which should be visible at any one
963            time. The widget will request a size  which  will  allow  XmNvisi‐
964            bleRows rows to be displayed.
965
966       XmNwrapType
967            When XmNmultiLineCell is true this resource specifies how to break
968            the lines. When set to XbaeWrapNone, lines are broken on  newlines
969            only.  When set to XbaeWrapContinuous, long lines are further bro‐
970            ken up so they fit in their cell. When  set  to  XbaeWrapWord  the
971            breaking of long lines occures preferably on spaces.
972
973       XmNwriteCellCallback
974            Specifies   a   list  of  callbacks to be called when a cell value
975            changes and an XmNdrawCellCallback is defined. A  pointer  to   an
976            XbaeMatrixWriteCellCallbackStruct is passed to the callbacks.  The
977            XmNwriteCellCallback allows data to be written back into  the  ap‐
978            plication's  data  structure  and  must be defined for an editable
979            XbaeMatrix with an XmNdrawCellCallback.
980
981       XmNxmRowLabels
982            Points to an array of XmStrings to be drawn to the  left  of  each
983            row.  If  XmNxmRowLabels  is NULL, XmNrowLabels will be used. This
984            resource is copied.
985
986       XmNxmColumnLabels
987            Points to an array of XmStrings to be drawn above each column.  If
988            XmNxmColumnLabels  is NULL, XmNcolumnLabels will be used. This re‐
989            source is copied.

Callback Information

1087       XbaeMatrixAnyCallbackStruct
1088            A  callback struct that is suitable for all callbacks that require
1089            the reason, event, row and column to be available.   Any  callback
1090            called  may  therefore  cast  the third parameter to the following
1091            struct in XbaeMatrix and can rest assured  that  evrything  in  it
1092            will be available.
1093
1094
1095            typedef struct
1096            {
1097                 XbaeReasonType   reason;
1098                 int              row;
1099                 int              column;
1100                 XEvent           *event;
1101            } XbaeMatrixAnyCallbackStruct;
1102
1103            Each  of  the  members  are  set to the appropriate struct for the
1104            callback.
1105
1106            If this idea is a little foreign to you,  recommended  reading  is
1107            K&R II page 213.
1108
1109       XmNdefaultActionCallback
1110            Callbacks on the XmNdefaultActionCallback list are called when the
1111            DefaultAction() action occurs.  The application can bind  the  De‐
1112            faultAction()  action  to  any  pointer based event. When a double
1113            click occurs on this pointer event, DefaultAction() will call  the
1114            callbacks  on  the XmNdefaultActionCallback list. A pointer to the
1115            following structure is passed to each callback on the  XmNdefault‐
1116            ActionCallback list:
1117
1118
1119            typedef struct
1120            {
1121                    XbaeReasonType       reason;
1122                    XEvent               *event;
1123                    int                  row;
1124                    int                  column;
1125            } XbaeMatrixDefaultActionCallbackStruct;
1126
1127
1128            reason    Set to XbaeDefaultActionReason .
1129
1130            event     The event that invoked this callback.
1131
1132            row       The row number of the cell in which the double click oc‐
1133                      curred.
1134
1135            column    The column number of the cell in which the double  click
1136                      occurred.
1137
1138            event
1139
1140            If  an application has an XmNdefaultActionCallback, then the call‐
1141            backs on the list will be called when the user clicks twice  in  a
1142            cell  within XmNdoubleClickInterval, enabling some action to occur
1143            for the particular cell.
1144
1145       XmNdrawCellCallback
1146            Callbacks on the XmNdrawCellCallback list are called when the wid‐
1147            get  needs to draw a cell. A pointer to the following structure is
1148            passed to each callback on the XmNdrawCellCallback list:
1149
1150
1151            typedef struct
1152            {
1153                 XbaeReasonType    reason;
1154                 XEvent            *event;
1155                 int               row;
1156                 int               column;
1157                 int               width;
1158                 int               height;
1159                 XbaeCellType      type;
1160                 String            string;
1161                 Pixmap            pixmap;
1162                 Pixmap            mask;
1163                 Pixel             foreground;
1164                 Pixel             background;
1165                 int               depth;
1166            } XbaeMatrixDrawCellCallbackStruct;
1167
1168
1169            reason    Set to XbaeDrawCellReason.
1170
1171            event     Always set to NULL
1172
1173            row       The row number of the cell that needs to be drawn.
1174
1175            column    The column number of the cell that needs to be drawn.
1176
1177            width     The width of the cell that needs to be drawn.
1178
1179            height    The height of the cell that needs to be drawn.
1180
1181            type      The type of ``data'' the programmer wants drawn  in  the
1182                      cell,  or  which  field  should be looked at for data to
1183                      draw:  string or pixmap.
1184
1185            string    The string to draw if  type  is  set  to  XbaeString  or
1186                      XbaeStringFree.
1187
1188            pixmap    The  pixmap  to  copy  if type is set to XbaePixmap.  It
1189                      will be clipped to width by height if necessary.
1190
1191            mask      A mask for the pixmap as obtained from the XPM  library.
1192                      mask  is  only necessary when pixmap has a depth greater
1193                      than one.
1194
1195            foreground
1196                      The foreground color of the cell.
1197
1198            background
1199                      The background color of the cell.
1200
1201            depth     The depth of the pixmap image (in bits per pixel).
1202
1203            If the application adds this callback, when the XbaeMatrix  deter‐
1204            mines that a cell at (row, column) needs to be redrawn, the normal
1205            cell drawing mechanism will be skipped and this callback called so
1206            the application can tell the widget what to put in the cell.
1207
1208            The  type field is defaulted to XbaeString and no cacheing or sav‐
1209            ing of the string or pixmap is done.
1210
1211            If the application sets type to XbaePixmap, the width, height  and
1212            depth  of  the  returned  pixmap will be calculated with a call to
1213            XGetGeometry().  If the programmer wishes  to  supply  the  width,
1214            height  and depth there is a marked improvement as a round trip to
1215            the X server is avoided.  Note that all geometry  parameters  must
1216            be supplied to ensure successful display of the pixmap.
1217
1218            If  a mask is also provided, it will be used to display the pixmap
1219            transparently.  Pixmaps drawn in cells also respect the  value  of
1220            XmNcolumnAlignments.
1221
1222            By defining an XmNdrawCellCallback the need for the storage of the
1223            XbaeMatrix data within the matrix is eliminated and can  prove  to
1224            be advantageous for memory usage.
1225
1226            To  write  the data back to the application, use the XmNwriteCell‐
1227            Callback described below.
1228
1229       XmNenterCellCallback
1230            Callbacks on the XmNenterCellCallback list are called from the Ed‐
1231            itCell() action just before a cell is edited to determine it's ed‐
1232            itability. A pointer to the following structure is passed to  each
1233            callback on the XmNenterCellCallback list:
1234
1235
1236            typedef struct
1237            {
1238                XbaeReasonType   reason;
1239                XEvent           *event;
1240                int              row;
1241                int              column;
1242                int              position;
1243                String           pattern;
1244                Boolean          auto_fill;
1245                Boolean          convert_case;
1246                Boolean          overwrite_mode;
1247                Boolean          select_text;
1248                Boolean          map;
1249                Cardinal         num_params;
1250                String           *params;
1251                Boolean          doit;
1252            } XbaeMatrixEnterCellCallbackStruct;
1253
1254
1255            reason    Set to XbaeEnterCellReason.
1256
1257            event     The event that invoked the callback.
1258
1259            row       The row number of the cell about to be edited.
1260
1261            column    The column number of the cell about to be edited.
1262
1263            position  The  location  of the cursor in the text field.  The de‐
1264                      fault is to place the cursor at the end of the string in
1265                      the cell.
1266
1267            pattern   A  pattern  for the XbaeInput widget (see XbaeInput(3)).
1268                      The default is to not specify a pattern.
1269
1270            auto_fill Used in conjunction with the setting of the  pattern  to
1271                      allow  literals  in  the pattern to be automatically in‐
1272                      serted.

1274            convert_case
1275                      If the pattern specifies an upper or lower case  letter,
1276                      the character typed in the position can automatically be
1277                      converted to the appropriate case when set to True.  The
1278                      default is to not convert the case of the typed letter.
1279
1280            overwrite_mode
1281                      Normally,  the  cursor  appears as the familiar I caret.
1282                      By setting overwrite_mode to True, the text  field  will
1283                      go  into  overwrite  mode  where  keystrokes replace the
1284                      character underneath the block cursor.
1285
1286            select_text
1287                      Indicates whether the text in the cell should  be  high‐
1288                      lighted (only valid if doit is set to True also.
1289
1290            map       Tells the matrix if the XmText should be mapped onto the
1291                      cell.  Only makes sense if doit is set to False.
1292
1293            num_params
1294                      The number of String parameters passed to the EditCell()
1295                      action.
1296
1297            params    An  array  containing  the  num_params String parameters
1298                      passed to the EditCell() action.
1299
1300            doit      Indicates whether or not this cell is editable.  Setting
1301                      doit  to False will make this cell not editable. The de‐
1302                      fault value is True.
1303
1304            If the application determines that the cell at  (row,  column)  is
1305            not  editable,  it  should set the doit flag to False.  If the map
1306            flag is also set to False, XbaeMatrix will not  place  the  XmText
1307            cell  editor on the cell.  If map is left as True, the XmText will
1308            be placed on the cell but the user will not  be  able  to  add  or
1309            delete characters from it. If the application leaves doit as True,
1310            then the TextField will be editable.  In addition, if  select_text
1311            is  set  to  True,  the  text in the cell will be selected via Xm‐
1312            TextSetSelection.  Assuming XmNpendingDelete  for  the  XmText  is
1313            also  True,  the selected text will be deleted as soon as the next
1314            text insertion occurs.
1315
1316       XmNlabelActivateCallback
1317            Callbacks on the XmNlabelActivateCallback list are called after  a
1318            button  label  has been activated via a mouse click.  A pointer to
1319            the following structure is passed to each callback on  the  XmNla‐
1320            belActivateCallback list:
1321
1322
1323            typedef struct
1324            {
1325                   XbaeReasonType      reason;
1326                   XEvent              *event;
1327                   int                 row;
1328                   int                 column;
1329                   Boolean             row_label;
1330                   String              label;
1331            } XbaeMatrixLabelActivateCallbackStruct;
1332
1333
1334            reason    Set to XbaeLabelActivateReason.
1335
1336            event     The event that invoked this callback.
1337
1338            row       The  row  number of the button label or -1 if the button
1339                      was a column label.
1340
1341            column    The column number of the button label or -1 if the  but‐
1342                      ton was a row label.
1343
1344            row_label If  the  button label that invoked the callback is a row
1345                      label, then this value is set to True.  If it was a col‐
1346                      umn label then it is set to False.
1347
1348            label     The label on the button that was pressed.
1349
1350            When  the  XbaeMatrix  receives  a ButtonRelease event on the same
1351            button label that it received a ButtonPress event, the XmNlabelAc‐
1352            tivateCallback is called to allow the programmer to respond to the
1353            event.  The callback has been provided  to  emulate  some  popular
1354            spreadsheets on the market.
1355
1356       XmNleaveCellCallback
1357            Callbacks on the XmNleaveCellCallback list are called from the Ed‐
1358            itCell() and CommitEdit() actions just before the edit to the cur‐
1359            rent  cell  is committed. The application can validate the changes
1360            made to the cell, and allow or disallow them.  A  pointer  to  the
1361            following  structure  is  passed to each callback on the XmNleave‐
1362            CellCallback list:
1363
1364
1365            typedef struct
1366            {
1367                 XbaeReasonType    reason;
1368                 XEvent            *event;
1369                 int               row, column;
1370                 String            value;
1371                 Boolean           doit;
1372
1373            } XbaeMatrixLeaveCellCallbackStruct;
1374
1375
1376            reason    Set to XbaeLeaveCellReason.
1377
1378            event     The event that invoked this callback.
1379
1380            row       The row number of the cell being edited.
1381
1382            column    The column number of the cell being edited.
1383
1384            value     Contains the new data which will be stored in this  cell
1385                      if  doit is True.  The memory pointed to by value may be
1386                      modified, or if the new contents  are  larger  than  the
1387                      current contents, then value should be set to point to a
1388                      larger piece of allocated memory.
1389
1390            doit      Indicates whether the edits applied to this cell  should
1391                      actually  be  stored  into  XbaeMatrix.  Setting doit to
1392                      False will cause the changes to  be  discarded  and  the
1393                      cell  will  retain its original value. The default value
1394                      is True.
1395
1396            If the application determines that the value entered in  the  cell
1397            at  (row,  column)  is  not  valid, it should set the doit flag to
1398            False. This will prevent the changes  from  being  stored  in  the
1399            cell.  The  TextField edit widget will remain on the current cell.
1400            If the application leaves doit as True, then the changes  made  to
1401            the cell will be committed and the TextField will move to the next
1402            cell or be unmapped. The application can also modify the String in
1403            value, e.g. to force a String to be all upper case.
1404
1405       XmNmodifyVerifyCallback
1406            Callbacks  on  the XmNmodifyVerifyCallback list are called while a
1407            cell is being edited. The callbacks are called before text is  in‐
1408            serted  into  or deleted from the TextField edit widget. A pointer
1409            to the following structure is passed to each callback on the  XmN‐
1410            modifyVerifyCallback list:
1411
1412
1413            typedef struct
1414            {
1415                XbaeReasonType               reason;
1416                XEvent                       *event;
1417                int                          row;
1418                int                          column;
1419                XmTextVerifyCallbackStruct   *verify;
1420                const char                   *prev_text;
1421            } XbaeMatrixModifyVerifyCallbackStruct;
1422
1423
1424            reason    Set to XbaeModifyVerifyReason.
1425
1426            event     Always set to NULL.
1427
1428            row       The row number of the cell being edited.
1429
1430            column    The column number of the cell being edited.
1431
1432            verify    The  contents  of  this  structure and its use are docu‐
1433                      mented in the XmText(3X) man page.
1434
1435            prev_text The contents of the cell as seen by this user before the
1436                      new  text.  If other text has already been entered, this
1437                      value will not match the official  XbaeMatrix  value  of
1438                      the  cell.   This  pointer  and the string should not be
1439                      modified.
1440
1441       XmNprocessDragCallback
1442            Callbacks on the XmNprocessDragCallback list are called  from  the
1443            ProcessDrag()  action.  The application can bind the ProcessDrag()
1444            action to any pointer based event, though by default it  is  bound
1445            to  the  Button2Down event.  When this event occurs, ProcessDrag()
1446            will call the callbacks  on  the  XmNprocessDragCallback  list.  A
1447            pointer  to  the following structure is passed to each callback on
1448            the XmNprocessDragCallback list:
1449
1450
1451            typedef struct
1452            {
1453                  XbaeReasonType      reason;
1454                  XEvent              *event;
1455                  int                 row;
1456                  int                 column;
1457                  String              string;
1458                  XbaeCellType        type;
1459                  Pixmap              pixmap;
1460                  Pixmap              mask;
1461                  Cardinal            num_params;
1462                  String              *params;
1463            } XbaeMatrixProcessDragCallbackStruct;
1464
1465
1466            reason    Set to XbaeProcessDragReason.
1467
1468            event     The XEvent which invoked the ProcessDrag() action.
1469
1470            row       The row number of the cell where  the  drag  was  initi‐
1471                      ated..
1472
1473            column    The  column number of the cell where the drag was initi‐
1474                      ated..
1475
1476            string    The string in the cell where the drag was  initiated  if
1477                      type  is XbaeString or XbaeStringFree.  This is provided
1478                      as a convenience to the application.
1479
1480            type      The type of the cell in which the drag was initiated.
1481
1482            pixmap    The pixmap in the cell where the drag was  initiated  if
1483                      type  is  XbaePixmap.  This is provided as a convenience
1484                      to the application.
1485
1486            mask      A mask for the pixmap as obtained from the XPM  library.
1487                      mask  is  only necessary when pixmap has a depth greater
1488                      than one.  Also provided as a convenience to the  appli‐
1489                      cation.
1490
1491            num_params
1492                      The  number  of String parameters passed to the Process‐
1493                      Drag() action.
1494
1495            params    An array containing  the  num_params  String  parameters
1496                      passed to the ProcessDrag() action.
1497
1498            The  application can use the XmNprocessDragCallback list to imple‐
1499            ment particular processing for Motif's drag-and-drop.
1500
1501       XmNresizeCallback
1502            Callbacks on the XmNresizeCallback list are called when the  Xbae‐
1503            Matrix widget is resized.  A pointer to the following structure is
1504            passed to
1505             each callback on the XmNresizeCallback list:
1506
1507
1508            typedef struct
1509            {
1510                  XbaeReasonType     reason;
1511                  XEvent             *event;
1512                  int                row;
1513                  int                column;
1514                  Dimension          width;
1515                  Dimension          height;
1516            } XbaeMatrixResizeCallbackStruct;
1517
1518
1519            reason    Set to XbaeResizeReason.
1520
1521            event     Always set to NULL
1522
1523            row       Set to the number of rows in the  matrix  (provided  for
1524                      convenience).
1525
1526            column    Set  to the number of colums in the matrix (provided for
1527                      convenience).
1528
1529            width     The new width of the XbaeMatrix widget.
1530
1531            height    The new height of the XbaeMatrix widget.
1532
1533            The application can use the XmNresizeCallback to adjust  such  re‐
1534            sources  as  XmNcolumnWidths, XmNvisibleColumns and XmNvisibleRows
1535            when the widget containing an XbaeMatrix widget is resized.
1536
1537       XmNresizeColumnCallback
1538            Callbacks on the XmNresizeColumnCallback list are  called  when  a
1539            column  of  the  XbaeMatrix  widget  is dynamically resized by the
1540            user.  A pointer to the following  structure  is  passed  to  each
1541            callback on the XmNresizeColumnCallback list:
1542
1543
1544            typedef struct
1545            {
1546                 XbaeReasonType     reason;
1547                 XEvent             *event;
1548                 int                row;
1549                 int                column;
1550                 int                which;
1551                 int                columns;
1552                 short              *column_widths;
1553            } XbaeMatrixResizeColumnCallbackStruct;
1554
1555
1556            reason    Set to XbaeResizeColumnReason.
1557
1558            event     The  XEvent that ended the resize.  The event will be of
1559                      type XButtonReleasedEvent.
1560
1561            row       The row in which the ResizeColumn() action began.
1562
1563            column    The column in which the ResizeColumn() action began (and
1564                      ended).
1565
1566            which     The  column  that  was resized in the ResizeColumn() ac‐
1567                      tion.
1568
1569            columns   The number of columns in the XbaeMatrix widget.
1570
1571            column_widths
1572                      The widths of each column as they stand  after  the  Re‐
1573                      sizeColumn() action.
1574
1575            The  application  can  use  the XmNresizeColumnCallback to perform
1576            post processing after a column has been resized.  By adjusting the
1577            values  contained  in column_widths the XbaeMatrix widget will use
1578            the values upon return from the callback.  Changing the number  of
1579            columns  in  the  matrix  in the XmNresizeColumnCallback should be
1580            used carefully as it may cause unexpected results.

1582
1583
1584       XmNselectCellCallback
1585            Callbacks on the XmNselectCellCallback list are  called  from  the
1586            SelectCell() action. The application can bind the SelectCell() ac‐
1587            tion to any pointer based event. When this event  occurs,  Select‐
1588            Cell()  will call the callbacks on the XmNselectCellCallback list.
1589            A pointer to the following structure is passed to each callback on
1590            the XmNselectCellCallback list:
1591
1592
1593            typedef struct
1594            {
1595                XbaeReasonType   reason;
1596                XEvent           *event;
1597                int              row;
1598                int              column;
1599                Boolean          **selected_cells;
1600                String           **cells;
1601                Cardinal         num_params;
1602                String           *params;
1603            } XbaeMatrixSelectCellCallbackStruct;
1604
1605
1606            reason    Set to XbaeSelectCellReason.
1607
1608            event     The XEvent which invoked the SelectCell() action.
1609
1610            row       The row number of the cell which was selected.
1611
1612            column    The column number of the cell which was selected.
1613
1614            selected_cells
1615                      The value of the XmNselectedCells resource. This is pro‐
1616                      vided as a convenience to the application  and  will  be
1617                      NULL if no cells have yet been selected.
1618
1619            cells     The  value of the XmNcells resource. This is provided as
1620                      a convenience to the application and will be NULL if  no
1621                      cells  have been specified or the XmNdrawCellCallback is
1622                      being used.
1623
1624            num_params
1625                      The number of String parameters passed  to  the  Select‐
1626                      Cell() action.
1627
1628            params    An  array  containing  the  num_params String parameters
1629                      passed to the SelectCell() action.
1630
1631            The application can use the XmNselectCellCallback list  to  imple‐
1632            ment  it's  own selection model. The XbaeMatrixSelectCellCallback‐
1633            Struct contains the array of String parameters passed to  the  Se‐
1634            lectCell()  action which invoked this callback. By binding the Se‐
1635            lectCell() action to various events via the  translation  manager,
1636            and using String action parameters to distinguish them, the appli‐
1637            cation can implement various selection models.  For  example,  the
1638            following translations could be used to implement a model in which
1639            a modifier key indicates whether a single cell or  an  entire  row
1640            should  be  selected.  The  callbacks on the XmNselectCellCallback
1641            list would examine the parameter and take the appropriate action.
1642
1643            #override\n\
1644                            Shift<Btn1Down>:   SelectCell(cell)\n\
1645                            Ctrl<Btn1Down>:    SelectCell(row)
1646
1647            The callbacks on the XmNselectCellCallback list can also  be  used
1648            in other ways, e.g. to pop up a cell specific menu.
1649
1650            NOTE:  If no cells have been selected, the value of selected_cells
1651            will be NULL.  The same applies for cells.  Care must be taken  so
1652            as not to dereference these members of the callback struct.
1653
1654       XmNtrackCellCallback
1655            Callbacks on the XmNtrackCellCallback list are being called by the
1656            HandleTracking() action, which is  triggered  by  pointer  motion.
1657            One  of  the  purposes of this callback list is to figure out from
1658            which cell to which cell the pointer is being moved.  A pointer to
1659            the  XbaeMatrixTrackCellCallbackStruct  structure is being passed.
1660            Its fields are defined as :
1661
1662
1663            typedef struct _XbaeMatrixTrackCellCallbackStruct
1664            {
1665                  XbaeReasonType     reason;
1666                  XEvent             *event;
1667                  int                row, column;
1668                  int                prev_row, prev_column;
1669                  Position           pointer_x, pointer_y;
1670            } XbaeMatrixTrackCellCallbackStruct;
1671
1672
1673            reason    Set to XbaeSelectCellReason.
1674
1675            event     The XEvent which invoked the HandleTracking() action.
1676
1677            row       This is the row number that the pointer is currently in.
1678
1679            column    This is the column number that the pointer is  currently
1680                      in.
1681
1682            prev_row  The row that the pointer was previously in.
1683
1684            prev_column
1685                      The column that the pointer was previously in.
1686
1687            pointer_x The x position of the pointer.
1688
1689            pointer_y The y position of the pointer.
1690
1691
1692       XmNtraverseCellCallback
1693            Callbacks  on the XmNtraverseCellCallback list are called from the
1694            EditCell() action and when XbaeMatrix receives  or  looses  focus.
1695            The  application  can  customize  cell traversal using these call‐
1696            backs.  XbaeMatrix has a default traversal order, outlined  below,
1697            which  the  application  can  override. A pointer to the following
1698            structure is passed to each callback on  the  XmNtraverseCellCall‐
1699            back list:
1700
1701
1702            typedef struct
1703            {
1704                XbaeReasonType   reason;
1705                XEvent           *event;
1706                int              row;
1707                int              column;
1708                int              next_row;
1709                int              next_column;
1710                int              fixed_rows;
1711                int              fixed_columns;
1712                int              trailing_fixed_rows;
1713                int              trailing_fixed_columns;
1714                int              num_rows;
1715                int              num_columns;
1716                String           param;
1717                XrmQuark         qparam;
1718            } XbaeMatrixTraverseCellCallbackStruct;
1719
1720            reason    Set to XbaeTraverseCellReason.
1721
1722            event     The event that invoked this callback.
1723
1724            row       The row number of the cell currently being edited.
1725
1726            column    The column number of the cell currently being edited.
1727
1728            next_row  The  row  number of the next cell to be edited, this can
1729                      be changed by the application.
1730
1731            next_column
1732                      The column number of the next cell to  be  edited,  this
1733                      can be changed by the application.
1734
1735            fixed_rows
1736                      The value of the XmNfixedRows resource. This is provided
1737                      as a convenience for the application in calculating  the
1738                      next_row and next_column fields.
1739
1740            fixed_columns
1741                      The  value of the XmNfixedColumns resource. This is pro‐
1742                      vided as a convenience for the application in  calculat‐
1743                      ing the next_row and next_column fields.
1744
1745            trailing_fixed_rows
1746                      The  value of the XmNtrailingFixedRows resource. This is
1747                      provided as a convenience for the application in  calcu‐
1748                      lating the next_row and next_column fields.
1749
1750            trailing_fixed_columns
1751                      The  value of the XmNtrailingFixedColumns resource. This
1752                      is provided as a convenience for the application in cal‐
1753                      culating the next_row and next_column fields.
1754
1755            num_rows  The value of the XmNrows resource. This is provided as a
1756                      convenience  for  the  application  in  calculating  the
1757                      next_row and next_column fields.
1758
1759            num_columns
1760                      The  value  of the XmNcolumns resource. This is provided
1761                      as a convenience for the application in calculating  the
1762                      next_row and next_column fields.
1763
1764            param     The  String  value  of the parameter passed to the Edit‐
1765                      Cell() action.
1766
1767            qparam    The XrmQuark value of the parameter passed to the  Edit‐
1768                      Cell() action.
1769
1770            The EditCell() action takes an arbitrary parameter which it passes
1771            through to the callbacks on the  XmNtraverseCellCallback  list  in
1772            both  String  and XrmQuark forms. The EditCell() action recognizes
1773            five special parameters which it uses to  implement  it's  default
1774            cell traversal. These parameters and their corresponding traversal
1775            results are:
1776
1777            Pointer   Set next_row and next_column to the cell underneath  the
1778                      mouse pointer.
1779
1780            Left      If  we  are  currently  editing cell (XmNfixedRows, XmN‐
1781                      fixedColumns), then do not move. Otherwise move one col‐
1782                      umn  to  the left, if that column is less than XmNfixed‐
1783                      Columns , then move up to the last  column  of  the  row
1784                      above.
1785
1786            Right     If  we  are  currently  editing  cell (XmNrows - 1, XmN‐
1787                      columns - 1), then do not move. Otherwise move one  col‐
1788                      umn  to  the  right,  if  that column is greater than or
1789                      equal to XmNcolumns , then move down to column XmNfixed‐
1790                      Columns of the row below.
1791
1792            Up        Move up one row. If that row is less than XmNfixedRows ,
1793                      then move to the last row.
1794
1795            Down      Move down one row. If that row is greater than or  equal
1796                      to XmNrows , then move to row XmNfixedRows.
1797
1798            If  the  EditCell() action recognizes one of these special parame‐
1799            ters, it calculates the new cell  to  be  edited  accordingly  and
1800            stores  the  results in the next_row and next_column fields of the
1801            XbaeMatrixTraverseCellCallbackStruct.  If EditCell() does not rec‐
1802            ognize  it's  parameter,  it  sets next_row and next_column to the
1803            current row and column.  It also stores a String and XrmQuark ver‐
1804            sion of it's parameter in the param and qparam fields.  EditCell()
1805            then calls the  callbacks  on  the  XmNtraverseCellCallback  list.
1806            These  callbacks  can  examine  the  parameter and recalculate the
1807            next_row and next_column fields  appropriately.   The  application
1808            can  override  the default calculation for the special parameters,
1809            or it can define an entirely new parameter  with  a  corresponding
1810            new  calculation.   It  would do this by binding EditCell() with a
1811            new application specific parameter to an event  in  a  translation
1812            table.  It is expected that application callbacks will use the Xr‐
1813            mQuark version of the parameter for efficiency reasons (by  stati‐
1814            cally  creating  the  new XrmQuarks and comparing them against the
1815            incoming qparam).
1816
1817            When XbaeMatrix receives the focus it will also call  the  XmNtra‐
1818            verseCellCallback  callbacks  before returning to the current cell
1819            or the upper left most  visible  cell  if  no  cell  is  currently
1820            edited.  The  XbaeMatrixTraverseCellCallbackStruct will have param
1821            and qparm set to Focus.  If there is no current cell row and  col‐
1822            umn will be set to -1.
1823
1824            When  XbaeMatrix looses the focus it will also call the XmNtraver‐
1825            seCellCallback with param and qparm set to LoosingFocus.
1826
1827       XmNvalueChangedCallback
1828            Callbacks on the XmNvalueChangedCallback list are called  while  a
1829            cell  is  being edited. The callbacks are called after text is in‐
1830            serted into or deleted from the TextField edit widget.  A  pointer
1831            to  the following structure is passed to each callback on the XmN‐
1832            valueChangedCallback list:
1833
1834
1835            typedef struct
1836            {
1837                  XbaeReasonType  reason;
1838                  XEvent  *event;
1839                  int     row;
1840                  int     column;
1841            } XbaeMatrixValueChangedCallbackStruct;
1842
1843
1844            reason    Set to XbaeValueChangedReason.
1845
1846            event     The event that triggered this callback.
1847
1848            row       The row number of the cell being edited.
1849
1850            column    The column number of the cell being edited.
1851
1852       XmNwriteCellCallback
1853            Callbacks (although it probably only makes sense to have  one)  on
1854            the  XmNwriteCellCallback list are called when the widget needs to
1855            write data to a cell, but only  when  XmNdrawCellCallback  is  de‐
1856            fined.  A  pointer  to  the  following structure is passed to each
1857            callback on the XmNwriteCellCallback list:
1858
1859
1860            typedef struct
1861            {
1862                   XbaeReasonType     reason;
1863                   XEvent             *event;
1864                   int                row;
1865                   int                column;
1866                   XbaeCellType       type;
1867                   String             string;
1868                   Pixmap             pixmap;
1869                   Pixmap             mask;
1870            } XbaeMatrixWriteCellCallbackStruct;
1871
1872
1873            reason    Set to XbaeWriteCellReason.
1874
1875            event     Always set to NULL
1876
1877            row       The row number of the cell that needs to be written.
1878
1879            column    The column number of the cell that needs to be written.
1880
1881            type      The type of  ``data''  contained  in  the  cell,  either
1882                      XbaeString or XbaePixmap.
1883
1884            string    The string to store if type is set to XbaeString.
1885
1886            pixmap    The  pixmap  to  store  if  type  is  set to XbaePixmap.
1887                      (maybe a little meaningless unless you can edit a pixmap
1888                      in a cell)
1889
1890            mask      A  mask for the pixmap as obtained from the XPM library.
1891                      mask is only necessary when pixmap has a  depth  greater
1892                      than one.
1893
1894            If  the application adds this callback, when the XbaeMatrix is ed‐
1895            itable and has been assigned an XmNdrawCellCallback, data  on  the
1896            widget  can  be  edited  and stored back in the application's data
1897            structure.  Only if an XmNdrawCellCallback has  been  assigned  to
1898            the XbaeMatrix widget, will the XmNwriteCellCallback be called.
1899
1900            At  the  moment, pixmap and mask will be sent to the XmNwriteCell‐
1901            Callback as NULL.
1902

Translations

1904       XbaeMatrix inherits translations from XmManager.  In addition,  XbaeMa‐
1905       trix uses the following translation:
1906
1907       :<Btn1Up>:                 DefaultAction()\n\
1908       :<Btn1Down>:               DefaultAction() EditCell(Pointer)\n\
1909       :Shift<Btn2Down>:          ResizeColumns()\n\
1910       :<Btn2Down>:               ProcessDrag()\n\
1911       :<Btn1Motion>:             HandleMotion() HandleTracking()()\n\
1912       :<Motion>:                 HandleTracking()()\n\
1913       :<Btn4Down>:               ScrollRows(-50)()\n\
1914       :<Btn5Down>:               ScrollRows( 50)()
1915
1916
1917       XbaeMatrix  installs  the  following default XmNtextTranslations on the
1918       TextField edit widget:
1919
1920       #override\n\
1921       Shift ~Ctrl ~Meta ~Alt <Key>Tab:   EditCell(Left)\n\
1922       ~Ctrl ~Meta ~Alt <Key>Tab:         EditCell(Right)\n\
1923       <Key>osfUp:                        EditCell(Up)\n\
1924       <Key>osfDown:                      EditCell(Down)\n\
1925       <Key>osfActivate:                  CommitEdit(False)\n\
1926       ~Shift ~Meta ~Alt <Key>Return:     CommitEdit(False)\n\
1927       <Key>osfCancel:                    CommitEdit(False)\n\
1928       Shift Ctrl ~Meta ~Alt <Key>Tab:    TraversePrev()\n\
1929       Ctrl ~Meta ~Alt <Key>Tab:          TraverseNext()\n\
1930       <Key>osfPageDown:                  PageDown()\n\
1931       <Key>osfPageUp:                    PageUp()\n

Action Routines

1935       CancelEdit()
1936              If the single parameter to CancelEdit() is the String True, then
1937              it  unmaps the edit TextField, discarding any changes which were
1938              made to the cell being edited. If the parameter is  False,  then
1939              CancelEdit()  restores  the  edit TextField to the original con‐
1940              tents of the cell, discarding any changes made to the cell being
1941              edited. The TextField is not unmapped.
1942
1943       CommitEdit()
1944              CommitEdit()  first calls any callbacks on the XmNleaveCellCall‐
1945              back list to determine if the changes made to the  current  cell
1946              are  valid.  If  they are, it then saves any changes made to the
1947              cell into the cell. If the callbacks on the XmNleaveCellCallback
1948              list  return  that  the changes are not valid, CommitEdit() does
1949              nothing.
1950
1951              If the changes are valid, CommitEdit() examines it's one parame‐
1952              ter, which must be the string True or False. If the parameter is
1953              True, then the edit TextField is unmapped. If it is False,  then
1954              the TextField is not unmapped.
1955
1956       DefaultAction()
1957              DefaultAction()  sets up a mechanism for determining whether two
1958              successive mouse clicks form a  double  click.   The  DefaultAc‐
1959              tion() should normally be used in conjunction with other pointer
1960              based events and provides  a  mechanism  for  acting  on  double
1961              clicks in a cell.
1962
1963       EditCell()
1964              EditCell() edits a new cell. EditCell() first calculates the new
1965              cell to edit based on it's single parameter. It then  calls  the
1966              callbacks  on  the XmNtraverseCellCallback list to allow them to
1967              specify a different cell to edit (see the discussion of  XmNtra‐
1968              verseCellCallback  above).   EditCell() then calls the callbacks
1969              on the XmNleaveCellCallback list to  determine  if  the  changes
1970              made  to  the current cell are valid. If they are, it then saves
1971              any changes made to the cell into the cell. If the  changes  are
1972              not valid, EditCell() does nothing further.
1973
1974              If  the changes are valid, EditCell() attempts to scroll the new
1975              cell to be edited so that it is fully visible. If the  new  cell
1976              is in a fixed row or column, EditCell() returns and does nothing
1977              further (these cells are not  editable).  Otherwise,  EditCell()
1978              calls  the  callbacks on the XmNenterCellCallback list to deter‐
1979              mine if the new cell is editable. It then moves the XmText  edit
1980              widget  to  the  new cell, setting it's editability based on the
1981              return from the XmNenterCellCallback callbacks.
1982
1983       ProcessDrag()
1984              ProcessDrag() calls the callbacks on the  XmNprocessDragCallback
1985              list, passing them a pointer to a XbaeMatrixProcessDragCallback‐
1986              Struct.
1987
1988       ResizeColumns()
1989              Allows the user to dynamically resize the  column  widths,  pro‐
1990              vided that XmNallowColumnResize is True.
1991
1992       ScrollRows()
1993              ScrollRows()  makes  the  rows of the matrix scroll by the pixel
1994              amount specified by it's argument.
1995
1996       ScrollColumns()
1997              ScrollColumns() makes the columns of the matrix  scroll  by  the
1998              pixel amount specified by it's argument.
1999
2000       SelectCell()
2001              SelectCell()  calls  the  callbacks on the XmNselectCellCallback
2002              list, passing them a pointer to a  XbaeMatrixSelectCellCallback‐
2003              Struct.   This  structure  will  contain  the  String parameters
2004              passed to the SelectCell() action, among other things  (see  the
2005              discussion of XmNselectCellCallback above).
2006
2007       TraverseNext()
2008              TraverseNext() will traverse out of the Matrix and into the next
2009              tab group.
2010
2011       TraversePrev()
2012              TraversePrev() will traverse out of the Matrix and into the pre‐
2013              vious tab group.
2014
2015       PageDown()
2016              PageDown()  causes  the  Matrix to scroll down a full page.  The
2017              text widget is placed on the first non  fixed  row  of  the  new
2018              page.
2019
2020       PageUp()
2021              PageUp()  causes  the Matrix to scroll up a full page.  The text
2022              widget is placed on the first non fixed row of the new page.
2023

Type Converters

2025       In addition to the standard type converters registered by Xt and Motif,
2026       XbaeMatrix registers the following additional type converters:
2027
2028       CvtStringToStringArray()
2029              Converts a comma separated list of Strings to an array of String
2030              pointers, one for each substring. Commas in the list may be  es‐
2031              caped  with  the  character  `\'. This converter allows the XmN‐
2032              rowLabels and XmNcolumnLabels resources to be specified  in  re‐
2033              source files.
2034
2035       CvtStringToWidthArray()
2036              Converts  a  comma separated list of numeric Strings to an array
2037              of short integers. This converter allows the XmNcolumnWidths re‐
2038              source to be specified in resource files.
2039
2040       CvtStringToMaxLengthArray()
2041              Converts  a  comma separated list of numeric Strings to an array
2042              of integers. This converter allows the  XmNcolumnMaxLengths  re‐
2043              source to be specified in resource files.
2044
2045       CvtStringToAlignmentArray()
2046              Converts a comma separated list of alignments to an array of un‐
2047              signed chars. This converter allows the XmNcolumnLabelAlignments
2048              and  XmNcolumnAlignments  resources  to be specified in resource
2049              files.
2050
2051       CvtStringToGridType()
2052              Converts a single string as discussed in XmNgridType to  a  grid
2053              type  value.   This converter allows XmNgridType to be specified
2054              in resource files.
2055
2056       CvtStringToMatrixScrollBarDisplayPolicy()
2057              Converts a single string as  discussed  in  XmNhorizontalScroll‐
2058              BarDisplayPolicy and XmNverticalScrollBarDisplayPolicy to a dis‐
2059              play policy value.  This converter  allows  XmNhorizontalScroll‐
2060              BarDisplayPolicy  and  XmNverticalScrollBarDisplayPolicy  to  be
2061              specified in resource files.
2062
2063       CvtStringToCellTable()
2064              Converts a comma separated list of  Strings  with  \n  delimited
2065              rows  to  a  two dimensional array of String pointers. This con‐
2066              verter allows the XmNcells resource to be specified in  resource
2067              files.
2068
2069       CvtStringToPixelTable()
2070              Converts a comma separated list of color names with \n delimited
2071              rows to a two dimensional array of Pixel values. This  converter
2072              allows the XmNcellBackgroundsandXmNcolors resources to be speci‐
2073              fied in resource files.
2074
2075       CvtStringToBooleanArray()
2076              Converts a comma separated list of string or numeric  values  to
2077              an  array  of Booleans.  The converter recongnises a comma sepa‐
2078              rated list of values. Each value is  parsed  such  that  if  the
2079              first  character is This converter allows the XmNcolumnButtonLa‐
2080              bels and XmNrowButtonLabels resources to  be  specified  in  re‐
2081              source files.

2119                  Pixel      *colors;
2120                  int        num_columns;
2121
2122
2123              w         An XbaeMatrix widget.
2124
2125              position  The column position before which to add the  new  col‐
2126                        umns.  Must be greater than or equal to zero, and less
2127                        than or equal to XmNcolumns.
2128
2129              columns   Points to an ordinary two dimensional array of String,
2130                        or NULL.  These Strings will be used to modify the Xm‐
2131                        Ncells resource to populate the new columns. Each  row
2132                        in the array must have XmNrows elements and represents
2133                        one of the new columns. columns must have  num_columns
2134                        rows. If columns is NULL, empty columns will be added.
2135
2136              labels    Points  to an array of String, or NULL.  These Strings
2137                        will be used as the XmNcolumnLabels for the  new  col‐
2138                        umns. The labels array must have num_columns elements.
2139                        If labels is NULL, and XmNcolumnLabels  is  set,  then
2140                        blank column labels will be used.
2141
2142              widths    Points  to  an  array  of short or NULL.  These values
2143                        will be used as the XmNcolumnWidths for the  new  col‐
2144                        umns. The widths array must have num_columns elements.
2145                        if widths is NULL then a default width  will  be  used
2146                        for the new columns.
2147
2148              max_lengths
2149                        Points to an array of int, or NULL.  These values will
2150                        be used as the XmNcolumnMaxLengths for  the  new  col‐
2151                        umns. The max_lengths array must have num_columns ele‐
2152                        ments. If max_lengths is NULL, then the  corresponding
2153                        value from widths will be used.
2154
2155              alignments
2156                        Points  to  an array of unsigned char, or NULL.  These
2157                        values will be used as the XmNcolumnAlignments for the
2158                        new  columns.  The alignments array must have num_col‐
2159                        umns elements. If alignments is  NULL,  then  XmALIGN‐
2160                        MENT_BEGINNING will be used.
2161
2162              label_alignments
2163                        Points  to  an array of unsigned char, or NULL.  These
2164                        values will be used  as  the  XmNcolumnLabelAlignments
2165                        for the new column labels.  The label_alignments array
2166                        must have num_columns elements. If label_alignments is
2167                        NULL, then XmALIGNMENT_BEGINNING will be used.
2168
2169              colors    Points  to  an  array of Pixel, or NULL.  These values

2171                        XmNcolors  table for the new columns. The colors array
2172                        must have num_columns elements.  If  colors  is  NULL,
2173                        then XmNforeground will be used.
2174
2175              num_columns
2176                        The  number  of  columns  which are being added to the
2177                        widget.
2178
2179              XbaeMatrixAddColumns() allows the application developer  to  dy‐
2180              namically  add  new  columns anywhere in the Matrix. The columns
2181              will be added before the column specified in  position.  Columns
2182              are  numbered  starting at zero.  To append new columns onto the
2183              end of the Matrix, specify position as the total number of  col‐
2184              umns.  Most  of  the  arguments to XbaeMatrixAddColumns() may be
2185              specified as NULL.  Default values will be used by the widget.
2186
2187              If the programmer attempts to add columns  using  XbaeMatrixAdd‐
2188              Columns()  when  there  are no rows, it will result in a warning
2189              message.  There must be at least one row in the XbaeMatrix  wid‐
2190              get to add columns.
2191
2192              To  maintain backward compatability, the cell backgrounds cannot
2193              be set in a call to XbaeMatrixAddColumns() and must be  set  (if
2194              so desired) in a separate call to XtVaSetValues().

2216                        the array must have XmNcolumns elements and represents
2217                        one  of the new rows. rows must have num_rows rows. If

2221                        will be used as the XmNrowLabels for the new rows. The
2222                        labels array must have num_rows elements. If labels is
2223                        NULL,  and  XmNrowLabels is set, then blank row labels
2224                        will be used
2225

2227                        will be used to set the corresponding rows in the XmN‐
2228                        colors table for the new rows. The colors  array  must
2229                        have  num_rows  elements. If colors is NULL, then XmN‐
2230                        foreground will be used.

2237              added  before  the  row specified in position. Rows are numbered
2238              starting at zero. To append new rows onto the end of the Matrix,
2239              specify position as the total number of rows.

2256
2257              XbaeMatrixCancelEdit() allows the application developer to  pro‐
2258              grammatically  cancel  a  cell  edit in progress, discarding any
2259              changes made by the user. This  function  unmaps  the  TextField
2260              edit  widget  if  the unmap flag is True. If unmap is False, the
2261              contents of the TextField are restored to their original  value,

2276
2277              XbaeMatrixCommitEdit()  can be used by the application developer
2278              to programmatically commit an edit, saving any changes  made  by
2279              the  user.   This  will cause the callbacks on the XmNleaveCell‐
2280              Callback list to be called to verify that the changes  the  user
2281              made  are  valid.  If the changes are valid, then they are saved
2282              into the cell and if the unmap flag is True, the TextField  wid‐
2283              get will be unmapped.

2428              cannot be edited and XbaeMatrixEditCell() will return. Next, the
2429              callbacks on the XmNenterCellCallback callback list  are  called
2430              for  the  specified cell to determine it's editability. Then the

2489              to find out which cell is the first selected.  The function tra‐
2490              verses  the  XbaeMatrix widget in a left to right, top to bottom
2491              manner to determine this value.  If no cell is selected, row and
2492              column are set to -1.

2502              XbaeMatrixFirstSelectedColumn() returns the column number of the
2503              first selected column in the XbaeMatrix  widget.   The  function
2504              traverses  the  matrix from column 0.  A column must be entirely
2505              selected for the column to be considered selected.  If no column
2506              is selected then -1 is returned.

2517              XbaeMatrixFirstSelectedRow() returns the row number of the first
2518              selected row in the XbaeMatrix widget.  The  function  traverses
2519              the  matrix from row 0.  A row must be entirely selected for the
2520              row to be considered selected.  If no row is selected then -1 is
2521              returned.

2540              cells, it is more efficient to do an XtGetValues()  on  XmNcells
2541              and examine the values in that array.

2848              umn()  draws  the  highlight around the column if XmNgridType is
2849              XmGRID_COLUMN_SHADOW or from around each cell in the column oth‐
2850              erwise.  The corresponding unsigned chars in the XmNhighlighted‐

2995              scrolled  into  the  visible  area of the XbaeMatrix widget.  By
2996              calling this function, the  XmNselectScrollVisible  resource  is
2997              ignored.  For a more accurate cell location after scrolling, the
2998              programmer should use the XmNleftColumnandXmNtopRow resources.

3041
3042              XbaeMatrixRefresh()  allows  the  application developer to force
3043              the widget to redraw itself.  This might be used when  the  pro‐
3044              grammer  knows  the widget's values have changed, but the widget
3045              has not detected the change.  For example, the quickest  way  to
3046              swap  the values of 2 rows would be to do an XtGetValues on XmN‐
3047              cells, swap the values of the 2 rows, and then do an XtSetValues
3048              on  XmNcells with the same StringTable variable.  Because of the
3049              way the Intrinsics work, the widget will not see this change and
3050              will  display the old values until a redraw is preformed because
3051              of a resize or scroll event (assuming no  other  change  in  the
3052              XtSetValues  caused a redraw).  Calling XbaeMatrixRefresh() will
3053              cause the correct values to be drawn and overcome  this  limita‐
3054              tion  in  the  Intrinsics.  While this function should rarely be
3055              needed, it is provided ``just in case''.

3071              XbaeMatrixRefreshCell() allows the application developer to  re‐

3073              larly useful when used with the XbaeMatrixDrawCellCallback as it
3074              allows updates of the data without an explicit expose event.

3817              the column otherwise.  The corresponding unsigned chars  in  the
3818              XmNhighlightedCells  array  will  be have its HighlightColumn or
3819              HighlightOther bit cleared, depending on whether XmNgridType  is
3820              set to XmGRID_COLUMN_SHADOW or not.

3865                        matrix.
3866
3867              XbaeMatrixVisibleCells() allows the the application developer to
3868              obtain the currently visible portion of the XbaeMatrix w.

3877
3878              XbaeMatrixVisibleColumns()  allows the the application developer
3879              to programmatically check how many columns  are  currently  dis‐
3880              played  in the XbaeMatrix w.  A partially visible column will be
3881              declared an entire column.

3899
3900
3901              XbaeGetVersionNum()  is a function that returns the numeric rep‐
3902              resentation of the version of the Xbae library that your program
3903              is  working with.  This is the run-time version of the Xbae wid‐
3904              gets, where XbaeVersion is a macro that represents the  compile-
3905              time version.
3906
3907              The  numeric representation is a simple calculation based on the
3908              major, minor, and pico numbers representing an Xbae  widget  re‐
3909              lease.  E.g. version 4.8.1 would be represented as 40801.
3910
3911              Releases prior to 4.8.0 didn't have this functionality.
3912
3913       XbaeGetVersionText()
3914
3915              char * XbaeGetVersionText()
3916
3917
3918              XbaeGetVersionText() is a function that returns the textual rep‐
3919              resentation of the version of the Xbae library that your program
3920              is  working with.  This is the run-time version of the Xbae wid‐
3921              gets, where XbaeVersionTxt is a macro that represents  the  com‐
3922              pile-time version.
3923

Additional Behavior

3925       Using XtSetValues to set the Matrix's XmNwidth resource to 0 will cause
3926       it to recompute it's horizontal size. It will request a new size  which
3927       results  in  XmNvisibleColumns  columns  being  displayed.  If XmNvisi‐
3928       bleColumns is 0, then it will request a new size such that it does  not
3929       need a horizontal ScrollBar (full horizontal size).
3930
3931       Using  XtSetValues  to  set  the  Matrix's XmNheight resource to 0 will
3932       cause it to recompute it's vertical size. It will request  a  new  size
3933       which results in XmNvisibleRows rows being displayed. If XmNvisibleRows
3934       is 0, then it will request a new size such that it does not need a ver‐
3935       tical ScrollBar (full vertical size).
3936
3937       An XtSetValues on XmNvisibleRows will cause the Matrix to request a new
3938       size which results in XmNvisibleRows non-fixed  rows  being  displayed,
3939       only if the new value is different than the old one.
3940
3941       An  XtSetValues on XmNvisibleColumns will cause the Matrix to request a
3942       new size which results in the first XmNvisibleColumns non-fixed columns
3943       being displayed, only if the new value is different than the old one.
3944
3945       An XtSetValues on any other resource will not result in a request for a
3946       new size. Setting other resources in conjunction with setting  XmNwidth
3947       and/or XmNheight to 0 allows for more control of the Matrix's geometry.
3948
3949       An  XtSetValues  setting  XmNrowLabelWidth to 0 will cause XmNrowLabel‐
3950       Width to be set to the width of the longest row label.
