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 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 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 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 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 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 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 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 The XmNdefaultActionCallback is provided to allow a double click action
70 in a cell to perform some function.
71 Motif's Drag and Drop functionality can be achieved via the XmNprocess‐
73 DragCallback.
74 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.
80
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.

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).

314 This resource cannot be specified in a resource file
315 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 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 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 XmNboldLabels
331 Overstrikes the row and column labels to create a bold font ap‐
332 pearance when True.
333 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 XmNbuttonLabelBackground
343 Specifies a Pixel value in which to draw the XmNbuttonLabels.
344 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 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 *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 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 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 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 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 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 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 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 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 String rows[2][3] =
423 {
424 "00", "01", "02",
425 "10", "11", "12"
426 };
427 String *cells[2];
429 cells[0] = &rows[0][0];
430 cells[1] = &rows[1][0];
431 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 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 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 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 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 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 XmNcolumnLabelColor
479 Specifies a Pixel value in which to draw the XmNcolumnLabels.
480 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 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 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 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 XmNcolumnWidthInPixels
509 Specifies wether the elements of XmNcolumnWidths are measured in
510 pixels or characters.
511 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 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 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 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 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 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 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 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 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 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 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 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 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 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 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 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 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 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 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 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 When drawing a label, the matrix uses the first entry with the tag
671 XmFONTLIST_DEFAULT_TAG.
672 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 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 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 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 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 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 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 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 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 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 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 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 XmNresizeCallback
740 Specifies a list of callbacks to be called when the matrix is re‐
741 sized.
742 XmNresizeColumnCallback
744 Specifies a list of callbacks to be called when a column is dynam‐
745 ically resized by the user.

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 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 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 XmNrowLabelColor
766 Specifies a Pixel value in which to draw the XmNrowLabels.
767 XmNrowLabelWidth
769 Specifies the width of the row labels. XmNrowLabelWidth defaults
770 to the width of the longest row label.
771 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 XmNrowHeightInPixels
781 Specifies wether the elements of XmNrowHeights are measured in
782 pixels or lines.
783 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 XmNrowShadowTypes

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 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 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.
810 XmNselectCellCallback
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 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 XmNselectedBackground
825 Allows the background of selected cells in XmNselectedCells to be
826 specified.
827 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 XmNselectedForeground
838 Allows the foreground of selected cells in XmNselectedCells to be
839 specified.
840 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 XmNshowArrows
848 Specifies whether arrows should be drawn when data in a cell has
849 been obscured due to the value of XmNcolumnWidths.
850 XmNspace
852 Specifies the distance that separates the ScrollBars from the cell
853 grid. The default value is 4 pixels.
854 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 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 XmNtextField
867 The widget ID of the XmText. This resource cannot be set to a new
868 value.
869 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 XmNtextTranslations
876 Specifies the XmNtranslations resource of the XmText cell edit
877 widget. See the description of XmNtranslations in XmText(3X).
878 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 XmNtrackCellCallback
889 specifies a list of callbacks to be called when the mouse pointer
890 is being moved.
891 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 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 XmNtrailingFixedColumns
903 Specifies the number of trailing columns (starting from the right
904 column) which should not be horizontally scrollable. XmNtrailing‐

914 set to True.
915 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 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 XmNuseXbaeInput

939 source.
940 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 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 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 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 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 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 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 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.
990
992 The following table lists the resources which XbaeMatrix inherits from
993 it's superclasses XmManager, Compositeand Core. For a complete de‐
994 scription of each resource, refer to the man page for that superclass.
995 The codes in the ``Access'' column indicate whether the given resource
996 can be set at creation time (C), or set by using XtSetValues (S), or
997 retrieved by using XtGetValues (G).

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 typedef struct
1096 {
1097 XbaeReasonType reason;
1098 int row;
1099 int column;
1100 XEvent *event;
1101 } XbaeMatrixAnyCallbackStruct;
1102 Each of the members are set to the appropriate struct for the
1104 callback.
1105 If this idea is a little foreign to you, recommended reading is
1107 K&R II page 213.
1108 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 typedef struct
1120 {
1121 XbaeReasonType reason;
1122 XEvent *event;
1123 int row;
1124 int column;
1125 } XbaeMatrixDefaultActionCallbackStruct;
1126 reason Set to XbaeDefaultActionReason .
1129 event The event that invoked this callback.
1131 row The row number of the cell in which the double click oc‐
1133 curred.
1134 column The column number of the cell in which the double click
1136 occurred.
1137 event
1139 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 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 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 reason Set to XbaeDrawCellReason.
1170 event Always set to NULL
1172 row The row number of the cell that needs to be drawn.
1174 column The column number of the cell that needs to be drawn.
1176 width The width of the cell that needs to be drawn.
1178 height The height of the cell that needs to be drawn.
1180 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 string The string to draw if type is set to XbaeString or
1186 XbaeStringFree.
1187 pixmap The pixmap to copy if type is set to XbaePixmap. It
1189 will be clipped to width by height if necessary.
1190 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 foreground
1196 The foreground color of the cell.
1197 background
1199 The background color of the cell.
1200 depth The depth of the pixmap image (in bits per pixel).
1202 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 The type field is defaulted to XbaeString and no cacheing or sav‐
1209 ing of the string or pixmap is done.
1210 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 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 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 To write the data back to the application, use the XmNwriteCell‐
1227 Callback described below.
1228 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 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 reason Set to XbaeEnterCellReason.
1256 event The event that invoked the callback.
1258 row The row number of the cell about to be edited.
1260 column The column number of the cell about to be edited.
1262 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 pattern A pattern for the XbaeInput widget (see XbaeInput(3)).
1268 The default is to not specify a pattern.
1269 auto_fill Used in conjunction with the setting of the pattern to
1271 allow literals in the pattern to be automatically in‐
1272 serted.
1273 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 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 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 map Tells the matrix if the XmText should be mapped onto the
1291 cell. Only makes sense if doit is set to False.
1292 num_params
1294 The number of String parameters passed to the EditCell()
1295 action.
1296 params An array containing the num_params String parameters
1298 passed to the EditCell() action.
1299 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 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 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 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 reason Set to XbaeLabelActivateReason.
1335 event The event that invoked this callback.
1337 row The row number of the button label or -1 if the button
1339 was a column label.
1340 column The column number of the button label or -1 if the but‐
1342 ton was a row label.
1343 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 label The label on the button that was pressed.
1349 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 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 typedef struct
1366 {
1367 XbaeReasonType reason;
1368 XEvent *event;
1369 int row, column;
1370 String value;
1371 Boolean doit;
1372 } XbaeMatrixLeaveCellCallbackStruct;
1374 reason Set to XbaeLeaveCellReason.
1377 event The event that invoked this callback.
1379 row The row number of the cell being edited.
1381 column The column number of the cell being edited.
1383 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 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 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 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 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 reason Set to XbaeModifyVerifyReason.
1425 event Always set to NULL.
1427 row The row number of the cell being edited.
1429 column The column number of the cell being edited.
1431 verify The contents of this structure and its use are docu‐
1433 mented in the XmText(3X) man page.
1434 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 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 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 reason Set to XbaeProcessDragReason.
1467 event The XEvent which invoked the ProcessDrag() action.
1469 row The row number of the cell where the drag was initi‐
1471 ated..
1472 column The column number of the cell where the drag was initi‐
1474 ated..
1475 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 type The type of the cell in which the drag was initiated.
1481 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 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 num_params
1492 The number of String parameters passed to the Process‐
1493 Drag() action.
1494 params An array containing the num_params String parameters
1496 passed to the ProcessDrag() action.
1497 The application can use the XmNprocessDragCallback list to imple‐
1499 ment particular processing for Motif's drag-and-drop.
1500 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 typedef struct
1509 {
1510 XbaeReasonType reason;
1511 XEvent *event;
1512 int row;
1513 int column;
1514 Dimension width;
1515 Dimension height;
1516 } XbaeMatrixResizeCallbackStruct;
1517 reason Set to XbaeResizeReason.
1520 event Always set to NULL
1522 row Set to the number of rows in the matrix (provided for
1524 convenience).
1525 column Set to the number of colums in the matrix (provided for
1527 convenience).
1528 width The new width of the XbaeMatrix widget.
1530 height The new height of the XbaeMatrix widget.
1532 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 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 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 reason Set to XbaeResizeColumnReason.
1557 event The XEvent that ended the resize. The event will be of
1559 type XButtonReleasedEvent.
1560 row The row in which the ResizeColumn() action began.
1562 column The column in which the ResizeColumn() action began (and
1564 ended).
1565 which The column that was resized in the ResizeColumn() ac‐
1567 tion.
1568 columns The number of columns in the XbaeMatrix widget.
1570 column_widths
1572 The widths of each column as they stand after the Re‐
1573 sizeColumn() action.
1574 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.
1581 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 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 reason Set to XbaeSelectCellReason.
1607 event The XEvent which invoked the SelectCell() action.
1609 row The row number of the cell which was selected.
1611 column The column number of the cell which was selected.
1613 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 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 num_params
1625 The number of String parameters passed to the Select‐
1626 Cell() action.
1627 params An array containing the num_params String parameters
1629 passed to the SelectCell() action.
1630 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 #override\n\
1644 Shift<Btn1Down>: SelectCell(cell)\n\
1645 Ctrl<Btn1Down>: SelectCell(row)
1646 The callbacks on the XmNselectCellCallback list can also be used
1648 in other ways, e.g. to pop up a cell specific menu.
1649 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 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 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 reason Set to XbaeSelectCellReason.
1674 event The XEvent which invoked the HandleTracking() action.
1676 row This is the row number that the pointer is currently in.
1678 column This is the column number that the pointer is currently
1680 in.
1681 prev_row The row that the pointer was previously in.
1683 prev_column
1685 The column that the pointer was previously in.
1686 pointer_x The x position of the pointer.
1688 pointer_y The y position of the pointer.
1690 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 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 reason Set to XbaeTraverseCellReason.
1721 event The event that invoked this callback.
1723 row The row number of the cell currently being edited.
1725 column The column number of the cell currently being edited.
1727 next_row The row number of the next cell to be edited, this can
1729 be changed by the application.
1730 next_column
1732 The column number of the next cell to be edited, this
1733 can be changed by the application.
1734 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 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 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 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 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 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 param The String value of the parameter passed to the Edit‐
1765 Cell() action.
1766 qparam The XrmQuark value of the parameter passed to the Edit‐
1768 Cell() action.
1769 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 Pointer Set next_row and next_column to the cell underneath the
1778 mouse pointer.
1779 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 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 Up Move up one row. If that row is less than XmNfixedRows ,
1793 then move to the last row.
1794 Down Move down one row. If that row is greater than or equal
1796 to XmNrows , then move to row XmNfixedRows.
1797 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 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 When XbaeMatrix looses the focus it will also call the XmNtraver‐
1825 seCellCallback with param and qparm set to LoosingFocus.
1826 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 typedef struct
1836 {
1837 XbaeReasonType reason;
1838 XEvent *event;
1839 int row;
1840 int column;
1841 } XbaeMatrixValueChangedCallbackStruct;
1842 reason Set to XbaeValueChangedReason.
1845 event The event that triggered this callback.
1847 row The row number of the cell being edited.
1849 column The column number of the cell being edited.
1851 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 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 reason Set to XbaeWriteCellReason.
1874 event Always set to NULL
1876 row The row number of the cell that needs to be written.
1878 column The column number of the cell that needs to be written.
1880 type The type of ``data'' contained in the cell, either
1882 XbaeString or XbaePixmap.
1883 string The string to store if type is set to XbaeString.
1885 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 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 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 At the moment, pixmap and mask will be sent to the XmNwriteCell‐
1901 Callback as NULL.
1902
1904 XbaeMatrix inherits translations from XmManager. In addition, XbaeMa‐
1905 trix uses the following translation:
1906 :<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 XbaeMatrix installs the following default XmNtextTranslations on the
1918 TextField edit widget:
1919 #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
1932
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 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 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 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 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 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 ProcessDrag()
1984 ProcessDrag() calls the callbacks on the XmNprocessDragCallback
1985 list, passing them a pointer to a XbaeMatrixProcessDragCallback‐
1986 Struct.
1987 ResizeColumns()
1989 Allows the user to dynamically resize the column widths, pro‐
1990 vided that XmNallowColumnResize is True.
1991 ScrollRows()
1993 ScrollRows() makes the rows of the matrix scroll by the pixel
1994 amount specified by it's argument.
1995 ScrollColumns()
1997 ScrollColumns() makes the columns of the matrix scroll by the
1998 pixel amount specified by it's argument.
1999 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 TraverseNext()
2008 TraverseNext() will traverse out of the Matrix and into the next
2009 tab group.
2010 TraversePrev()
2012 TraversePrev() will traverse out of the Matrix and into the pre‐
2013 vious tab group.
2014 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 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
2025 In addition to the standard type converters registered by Xt and Motif,
2026 XbaeMatrix registers the following additional type converters:
2027 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 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 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 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 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 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 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 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 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.
2082
2084 The following external entry points to XbaeMatrix class methods are de‐
2085 fined:
2086 XbaeCreateMatrix()
2088 Widget XbaeCreateMatrix()
2090 Widget parent;
2091 String name;
2092 ArgList arglist;
2093 Cardinal argcount;
2094 parent Specifies the parent widget ID.
2097 name Specifies the name of the created widget
2099 arglist Specifies the argument list
2101 argcount Specifies the number of attribute/value pairs in the
2103 argument list (arglist)
2104 XbaeCreateMatrix() creates an unmanaged instance of an XbaeMa‐
2106 trix widget and returns the associated widget ID.
2107 XbaeMatrixAddColumns()
2109 void XbaeMatrixAddColumns()
2111 Widget w;
2112 int position;
2113 String *columns;
2114 String *labels;
2115 short *widths;
2116 int *max_lengths;
2117 unsigned char *alignments;
2118 unsigned char *label_alignments;
2119 Pixel *colors;
2120 int num_columns;
2121 w An XbaeMatrix widget.
2124 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 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 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 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 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 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 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 colors Points to an array of Pixel, or NULL. These values
2170 will be used to set the corresponding columns in the
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 num_columns
2176 The number of columns which are being added to the
2177 widget.
2178 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 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 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().

2210 Must be greater than or equal to zero, and less than
2211 or equal to XmNrows.
2212 rows Points to an ordinary two dimensional array of String,
2214 or NULL. These Strings will be used to modify the Xm‐
2215 Ncells resource to populate the new rows. Each row in
2216 the array must have XmNcolumns elements and represents
2217 one of the new rows. rows must have num_rows rows. If
2218 rows is NULL, empty rows will be added.
2219 labels Points to an array of String, or NULL. These Strings
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 colors Points to an array of Pixel, or NULL. These values
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.
2231 num_rows The number of rows which are being added to the wid‐
2233 get.
2234 XbaeMatrixAddRows() allows the application developer to dynami‐
2236 cally add new rows anywhere in the Matrix. The rows will be
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.
2240 To maintain backward compatability, the cell backgrounds cannot
2242 be set in a call to XbaeMatrixAddRows() and must be set (if so
2243 desired) in a separate call to XtVaSetValues().

2255 should be unmapped after the edit is canceled.
2256 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,
2262 and the TextField is not unmapped.
2263 XbaeMatrixCommitEdit()
2265 Boolean XbaeMatrixCommitEdit()
2267 Widget w;

2274 should be unmapped after an edit is successfully com‐
2275 mitted.
2276 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.

2419 XbaeMatrixEditCell()
2421 allows the application developer to programmatically force a
2423 specific cell to be edited. This function will first attempt to
2424 commit the edit in the current cell. If the XmNleaveCellCallback
2425 callbacks disallow this commit, then XbaeMatrixEditCell() will
2426 return. Otherwise the specified cell is scrolled until it is
2427 visible. If the specified cell is in a fixed row or column, it
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
2431 TextField edit widget is mapped on top of the specified cell.

2934 int column;
2935 w An XbaeMatrix widget.
2938 column The column of the matrix to check.
2940 XbaeMatrixIsColumnVisible() allows the application developer to
2942 determine whether or not a particular column is in the visible
2943 area of the XbaeMatrix widget. The function returns True if the
2944 column is visible and False otherwise.
2945 XbaeMatrixIsRowSelected()
2947 Boolean XbaeMatrixIsRowSelected()
2949 Widget w;
2950 int row;
2951 w An XbaeMatrix widget.
2954 row The row of the matrix to check.
2956 XbaeMatrixIsRowSelected() allows the application developer to
2958 determine whether or not a particular row is selected. The func‐
2959 tion returns True if the row is selected and False otherwise. A
2960 row must be selected in its entirety for XbaeMatrixIsRowSe‐
2961 lected() to return True.
2962 XbaeMatrixIsRowVisible()
2964 Boolean XbaeMatrixIsRowVisible()
2966 Widget w;
2967 int row;
2968 w An XbaeMatrix widget.
2971 row The row of the matrix to check.
2973 XbaeMatrixIsRowVisible() allows the application developer to de‐
2975 termine whether or not a particular row is in the visible area
2976 of the XbaeMatrix widget. The function returns True if the row
2977 is visible and False otherwise.
2978 XbaeMatrixMakeCellVisible()
2980 int XbaeMatrixMakeCellVisible()
2982 Widget w;
2983 int row;
2984 int column;
2985 w An XbaeMatrix widget.
2988 row The row to scroll into the visible area of the matrix.
2990 column The column to scroll into the visible area of the ma‐
2992 trix.
2993 XbaeMatrixMakeCellVisible() allows a cell to be programatically
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.
2999 XbaeMatrixNumRows()
3001 int XbaeMatrixNumRows()
3003 Widget w;
3004 w An XbaeMatrix widget.
3007 XbaeMatrixNumRows() returns the number of rows in the given ma‐
3009 trix.
3010 XbaeMatrixNumColumns()
3013 int XbaeMatrixNumColumns()
3015 Widget w;
3016 w An XbaeMatrix widget.
3019 XbaeMatrixNumColumns() returns the number of columns in the
3021 given matrix.
3022 XbaeMatrixNumRows()
3024 int XbaeMatrixNumRows()
3026 Widget w;
3027 w An XbaeMatrix widget.
3030 XbaeMatrixNumRows() returns the number of rows in the given ma‐
3032 trix.
3033 XbaeMatrixRefresh()
3035 void XbaeMatrixRefresh()
3037 Widget w;
3038 w An XbaeMatrix widget.
3041 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''.
3056 XbaeMatrixRefreshCell()
3058 void XbaeMatrixRefreshCell()

3068 column The column of the cell to redraw.
3070 XbaeMatrixRefreshCell() allows the application developer to re‐
3072 draw a specific cell of the matrix. This function is particu‐
3073 larly useful when used with the XbaeMatrixDrawCellCallback as it
3074 allows updates of the data without an explicit expose event.
3075 XbaeMatrixRefreshColumn()
3077 void XbaeMatrixRefreshColumn()
3079 Widget w;
3080 int column;
3081 w An XbaeMatrix widget.

3088 efficiently redraw a specific column
3089 of the matrix.
3090 XbaeMatrixRefreshRow()
3092 void XbaeMatrixRefreshRow()
3094 Widget w;
3095 int row;
3096 w An XbaeMatrix widget.
3099 row The row of the matrix to redraw.
3101 XbaeMatrixRefreshRow() allows the application developer to effi‐
3103 ciently redraw a specific row
3104 of the matrix.

3121 x The x coordinate returned that represents the left co‐
3123 ordinates of the given cell.
3124 y The y coordinate returned that represents the upper
3126 coordinates of the given cell.
3127 XbaeMatrixRowColToXY() allows the application developer to de‐
3129 termine the coordinates of the upper left corner of a given
3130 cell. If the given widget is not an XbaeMatrix widget, False
3131 will be returned and the values of x and y will be undefined.
3132 This function is useful for drag and drop calculations.
3133 XbaeMatrixSelectAll()
3135 void XbaeMatrixSelectAll()
3137 Widget w;
3138 w An XbaeMatrix widget.
3141 XbaeMatrixSelectAll() allows the application developer to pro‐
3143 grammatically select all cells. XbaeMatrixSelectAll() redraws

3158 column The column of the cell to select.
3160 XbaeMatrixSelectCell() allows the application developer to pro‐
3162 grammatically select a cell. XbaeMatrixSelectCell() first
3163 scrolls the specified cell until it is visible, and then draws
3164 the cell in reverse video (or selectedForeground / selectedBack‐
3165 ground if set).
3166 The corresponding Boolean in the XmNselectedCells array will be
3167 set to True.
3168 XbaeMatrixSelectColumn()
3170 void XbaeMatrixSelectColumn()

3174 w An XbaeMatrix widget.
3177 column The column to select.
3179 XbaeMatrixSelectColumn() allows the application developer to
3181 programmatically select a column. XbaeMatrixSelectColumn()
3182 first scrolls the specified column until it is visible, and then
3183 draws the column in reverse video (or selectedForeground / se‐
3184 lectedBackground if set). The corresponding Booleans in the
3185 XmNselectedCells array will be set to True.
3186 XbaeMatrixSelectRow()

3243 XbaeMatrixSetCellBackground() is a convenient way to specify and
3245 modify the XmNcellBackgrounds resource when changing the back‐
3246 ground of a single cell. If XmNcellBackgrounds is NULL, then
3247 XbaeMatrixSetCellBackground() will create a Pixel table initial‐
3248 ized to XmNforeground except for the cell specified in it's ar‐
3249 guments. If XmNcellBackgrounds is not NULL, then XbaeMatrixSet‐
3250 CellBackground() will changed the specified cell in that re‐
3251 source to the specified color.

3297 variable
3298 mask the function will store the contents of this variable
3300 as the pixmap mask
3301 XbaeMatrixSetCellPixmap will set the pixmap and the associated
3303 mask of the indicated cell. If the row or column are out of
3304 bounds, or the widget is not an XbaeMatrix widget, then nothing
3305 is changed; this erroneous condition is silently ignored.
3306 XbaeMatrixSetCellShadow()
3308 void XbaeMatrixSetCellShadow()

3730 user_data a pointer the application can use for its own needs.
3732 XbaeMatrixSortColumns allows you to sort the columns in the
3734 XbaeMatrix widget according to criteria determined by the proc
3735 function. The proc function should have the above signature and
3736 functionality as demanded by the qsort(3) function. It will be
3737 called with a the matrix being sorted, the indices of two col‐
3738 umns to compare and the user_data pointer XbaeMatrixSortColumns
3739 was called with. It should return -1, 0, or 1 as appropriate. It
3740 is guaranteed that the matrix does not change while sorting and
3741 the necessary reordering will only take place after the last
3742 call to proc has been made.

3814 to programmatically unhighlight a column. XbaeMatrixUnhigh‐
3815 lightColumn() erases the highlight from around the column if Xm‐
3816 NgridType is XmGRID_COLUMN_SHADOW or from around each cell in
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.
3821 XbaeMatrixUnhighlightRow()
3823 void XbaeMatrixUnhighlightRow()
3825 Widget w;
3826 int row;
3827 w An XbaeMatrix widget.
3830 row The row to unhighlight.
3832 XbaeMatrixUnhighlightRow() allows the application developer to
3834 programmatically unhighlight a row. XbaeMatrixUnhighlightRow()
3835 erases the highlight from around the row if XmNgridType is Xm‐
3836 GRID_ROW_SHADOW or from around each cell in the row otherwise.
3837 The corresponding unsigned chars in the XmNhighlightedCells ar‐
3838 ray will be have its HighlightRow or HighlightOther bit cleared,
3839 depending on whether XmNgridType is set to XmGRID_ROW_SHADOW or
3840 not.
3841 XbaeMatrixVisibleCells()
3843 int XbaeMatrixVisibleCells()
3845 Widget w;
3846 int *top_row;
3847 int *bottom_row;
3848 int *left_column;
3849 int *right_column;
3850 w An XbaeMatrix widget.
3853 top_row The first row that is currently visible in the matrix.
3855 bottom_row
3857 The last row that is currently visible in the matrix.
3858 left_column
3860 The leftmost column that is currently visible in the
3861 matrix.
3862 right_column
3864 The rightmost column that is currently visible in the
3865 matrix.
3866 XbaeMatrixVisibleCells() allows the the application developer to
3868 obtain the currently visible portion of the XbaeMatrix w.
3869 XbaeMatrixVisibleColumns()
3871 int XbaeMatrixVisibleColumns()
3873 Widget w;
3874 w An XbaeMatrix widget.
3877 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.
3882 XbaeMatrixVisibleRows()
3884 int XbaeMatrixVisibleRows()
3886 Widget w;
3887 w An XbaeMatrix widget.
3890 XbaeMatrixVisibleRows() allows the the application developer to
3892 programmatically check how many rows are currently displayed in
3893 the XbaeMatrix w. A partially visible row will be declared an
3894 entire row.
3895 XbaeGetVersionNum()
3897 int XbaeGetVersionNum()
3899 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 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 Releases prior to 4.8.0 didn't have this functionality.
3912 XbaeGetVersionText()
3914 char * XbaeGetVersionText()
3916 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
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 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 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 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 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 An XtSetValues setting XmNrowLabelWidth to 0 will cause XmNrowLabel‐
3950 Width to be set to the width of the longest row label.
