21 Switch: -autoclear
22 Name: autoClear
23 Class: AutoClear
24 A boolean value which specifies whether the first keypress in a cell
25 will delete whatever text was previously there. Defaults to 0.
26 Switch: -bordercursor
28 Name: borderCursor
29 Class: Cursor
30 Specifies the name of the cursor to show when over borders, a visual
31 indication that interactive resizing is allowed (it is thus affect by
32 the value of -resizeborders). Defaults to crosshair .
33 Switch: -borderwidth or -bd
35 Name: borderWidth
36 Class: BorderWidth
37 Specifies a non-negative pixel value or list of values indicating the
38 width of the 3-D border to draw on interior table cells (if such a
39 border is being drawn; the <Brelief> option typically determines
40 this). If one value is specified, a rectangle of this width will be
41 drawn. If two values are specified, then only the left and right
42 edges of the cell will have borders. If four values are specified,
43 then the values correspond to the {left right top bottom} edges. This
44 can be overridden by the a tag's borderwidth option. It can also be
45 affected by the defined -drawmode for the table. Each value in the
46 list must have one of the forms acceptable to Tk_GetPixels.
47 Switch: -browsecommand or -browsecmd
49 Name: browseCommand
50 Class: BrowseCommand
51 Specifies a command (callback) which will be evaluated anytime the
52 active cell changes. The Previous Index and the Current index is
53 passed to this command as arguments.
54 Switch: -cache
56 Name: cache
57 Class: Cache
58 A boolean value that specifies whether an internal cache of the table
59 contents should be kept. This greatly enhances speed performance when
60 used with -command but uses extra memory. Can maintain state when
61 both -command and -variable are empty. The cache is automatically
62 flushed whenever the value of -cache or -variable changes, otherwise
63 you have to explicitly call clear on it. Defaults to off.
64 Switch: -colorigin
66 Name: colOrigin
67 Class: Origin
68 Specifies what column index to interpret as the leftmost column in the
69 table. This value is used for user indices in the table. Defaults to
70 0.
71 Switch: -cols
73 Name: cols
74 Class: Cols
75 Number of cols in the table. Defaults to 10.
76 Switch: -colseparator
78 Name: colSeparator
79 Class: Separator
80 Specifies a separator character that will be interpreted as the column
81 separator when cutting or pasting data in a table. By default,
82 columns are separated as elements of a tcl list.
83 Switch: -colstretchmode
85 Name: colStretchMode
86 Class: StretchMode
87 Specifies one of the following stretch modes for columns to fill extra
88 allocated window space:
89 none
91 Columns will not stretch to fill the assigned window space. If the
92 columns are too narrow, there will be a blank space at the right of
93 the table. This is the default.
94 unset
96 Only columns that do not have a specific width set will be stretched.
97 all
99 All columns will be stretched by the same number of pixels to fill
100 the window space allocated to the table. This mode can interfere
101 with interactive border resizing which tries to force column width.
102 last
104 The last column will be stretched to fill the window space allocated
105 to the table.
106 fill
108 (only valid for -rowstretch currently)
109 The table will get more or less columns according to the window space
111 allocated to the table. This mode has numerous quirks and may
112 disappear in the future.
113 Switch: -coltagcommand
115 Name: colTagCommand
116 Class: TagCommand
117 Provides the name of a procedure that will be evaluated by the widget
118 to determine the tag to be used for a given column. When displaying a
119 cell, the table widget will first check to see if a tag has been
120 defined using the tag col widget method. If no tag is found, it will
121 evaluate the named procedure passing the column number in question as
122 the sole argument. The procedure is expected to return the name of a
123 tag to use, or a null string. Errors occuring during the evaluation of
124 the procedure, or the return of an invalid tag name are silently
125 ignored.
126 The Current column number is passed as an argument to the col command.
128 Switch: -colwidth
130 Name: colWidth
131 Class: ColWidth
132 Default column width, interpreted as characters in the default font
133 when the number is positive, or pixels if it is negative. Defaults to
134 10.
135 Switch: -command
137 Name: command
138 Class: Command
139 Specified a command to use as a procedural interface to cell values.
140 If -usecommand is true, this command will be used instead of any
141 reference to the -variable array. When retrieving cell values, the
142 return value of the command is used as the value for the cell.
143 Args passed to this callback: The Set Flag (=1 if setting, else
145 retrieving), the current row, the current col, the cell value (if
146 setting).
147 Switch: -drawmode
149 Name: drawMode
150 Class: DrawMode
151 Sets the table drawing mode to one of the following options:
152 slow
154 The table is drawn to an offscreen pixmap using the Tk bordering
155 functions (double-buffering). This means there will be no flashing,
156 but this mode is slow for larger tables.
157 compatible
159 The table is drawn directly to the screen using the Tk border
160 functions. It is faster, but the screen may flash on update. This is
161 the default.
162 fast
164 The table is drawn directly to the screen and the borders are done
165 with fast X calls, so they are always one pixel wide only. As a side
166 effect, it restricts -borderwidth to a range of 0 or 1. This mode
167 provides best performance for large tables, but can flash on redraw
168 and is not 100% Tk compatible on the border mode.
169 single
171 The table is drawn to the screen as in fast mode, but only single
172 pixel lines are drawn (not square borders).
173 Switch: -flashmode
175 Name: flashMode
176 Class: FlashMode
177 A boolean value which specifies whether cells should flash when their
178 value changes. The table tag flash will be applied to these cells
179 for the duration specified by -flashtime . Defaults to 0.
180 Switch: -flashtime
182 Name: flashTime
183 Class: FlashTime
184 The amount of time, in 1/4 second increments, for which a cell should
185 flash when its value has changed. -flashmode must be on. Defaults
186 to 2.
187 Switch: -height
189 Name: height
190 Class: Height
191 Specifies the desired height for the window, in rows. If zero or less,
192 then the desired height for the window is made just large enough to
193 hold all the rows in the table. The height can be further limited by
194 -maxheight .
195 Switch: -invertselected
197 Name: invertSelected
198 Class: InvertSelected
199 Specifies whether the foreground and background of an item should
200 simply have their values swapped instead of merging the sel tag
201 options when the cell is selected. Defaults to 0 (merge sel tag).
202 Switch: -ipadx
204 Name: ipadX
205 Class: Pad
206 A pixel value specifying the internal offset X padding for text in a
207 cell. This value does not grow the size of the cell, it just causes
208 the text to be drawn further from the cell border. It only affects
209 one side (depending on anchor). Defaults to 0. See -padx for an
210 alternate padding style.
211 Switch: -ipady
213 Name: ipadY
214 Class: Pad
215 A pixel value specifying the internal offset Y padding for text in a
216 cell. This value does not grow the size of the cell, it just causes
217 the text to be drawn further from the cell border. It only affects
218 one side (depending on anchor). Defaults to 0. See -pady for an
219 alternate padding style.
220 Switch: -justify
222 Name: justify
223 Class: Justify
224 How to justify multi-line text in a cell. It must be one of left,
225 right, or center. Defaults to left.
226 Switch: -maxheight
228 Name: maxHeight
229 Class: MaxHeight
230 The max height in pixels that the window will request. Defaults to
231 600.
232 Switch: -maxwidth
234 Name: maxWidth
235 Class: MaxWidth
236 The max width in pixels that the window will request. Defaults to
237 800.
238 Switch: -multiline
240 Name: multiline
241 Class: Multiline
242 Specifies the default setting for the multiline tag option. Defaults
243 to 1.
244 Switch: -pady
246 Name: padX
247 Class: Pad
248 A pixel value specifying the offset X padding for a cell. This value
249 causes the default size of the cell to increase by two times the value
250 (one for each side), unless a specific pixel size is chosen for the
251 cell with the width command. This will force an empty area on the
252 left and right of each cell edge. This padding affects all types of
253 data in the cell. Defaults to 0. See -ipadx for an alternate padding
254 style.
255 Switch: -pady
257 Name: padY
258 Class: Pad
259 A pixel value specifying the offset Y padding for a cell. This value
260 causes the default size of the cell to increase by two times the value
261 (one for each side), unless a specific pixel size is chosen for the
262 cell with the height command. This will force an empty area on the
263 top and bottom of each cell edge. This padding affects all types of
264 data in the cell. Defaults to 0. See -ipadx for an alternate padding
265 style.
266 Switch: -resizeborders
268 Name: resizeBorders
269 Class: ResizeBorders
270 Specifies what kind of interactive border resizing to allow, must be
271 one of row, col, both (default) or none.
272 Switch: -rowheight
274 Name: rowHeight
275 Class:
276 RowHeight Default row height, interpreted as lines in the default
277 font when the number is positive, or pixels if it is negative.
278 Defaults to 1.
279 Switch: -roworigin
281 Name: rowOrigin
282 Class: Origin
283 Specifies what row index to interpret as the topmost row in the table.
284 This value is used for user indices in the table. Defaults to 0.
285 Switch: -rows
287 Name: rows
288 Class: Rows
289 Number of rows in the table. Defaults to 10.
290 Switch: -rowseparator
292 Name: rowSeparator
293 Class: Separator
294 Specifies a separator character that will be interpreted as the row
295 separator when cutting or pasting data in a table. By default, rows
296 are separated as tcl lists.
297 Switch: -rowstretchmode
299 Name: rowStretchMode
300 Class: StretchMode
301 Specifies the stretch modes for rows to fill extra allocated window
302 space. See -colstretchmode for valid options.
303 Switch: -rowtagcommand
305 Name: rowTagCommand
306 Class: TagCommand
307 Provides the name of a procedure that can evaluated by the widget to
308 determine the tag to be used for a given row. The procedure must be
309 defined by the user to accept a single argument (the row number), and
310 return a tag name or null string. This operates in a similar manner
311 as -coltagcommand , except that it applies to row tags.
312 The Current row number is passed as an argument to the row command.
314 Switch: -selectioncommand or -selcmd
316 Name: selectionCommand
317 Class: SelectionCommand
318 Specifies a command (callback) to evaluate when the selection is
319 retrieved from a table via the selection mechanism (ie: evaluating
320 "selection get "). The return value from this command will become the
321 string passed on by the selection mechanism. The following arguments
322 are passed to this callback: The number of rows in the selection,
323 number of columns in the selection, the selection string, the number
324 of cell in the selection.
325 Switch: -selectmode
327 Name: selectMode
328 Class: SelectMode
329 Specifies one of several styles for manipulating the selection. The
330 value of the option may be arbitrary, but the default bindings expect
331 it to be either single , browse , multiple , or extended ; the default
332 value is browse . These styles are like those for the Tk listbox,
333 except expanded for 2 dimensions.
334 Switch: -selecttitle
336 Name: selectTitles
337 Class: SelectTitles
338 Specifies whether title cells should be allowed in the selection.
339 Defaults to 0 (disallowed).
340 Switch: -selecttype
342 Name: selectType
343 Class: SelectType
344 Specifies one of several types of selection for the table. The value
345 of the option may be one of row , col , cell , or both (meaning row
346 && col ); the default value is cell . These types define whether an
347 entire row/col is affected when a cell's selection is changed (set or
348 clear).
349 Switch: -sparsearray
351 Name: sparseArray
352 Class: SparseArray
353 A boolean value that specifies whether an associated Tcl array should
354 be kept as a sparse array (1, the default) or as a full array (0). If
355 true, then cell values that are empty will be deleted from the array
356 (taking less memory). If false, then all values in the array will be
357 maintained.
358 Switch: -state
360 Name: state
361 Class: State
362 Specifies one of two states for the entry: normal or disabled. If
363 the table is disabled then the value may not be changed using widget
364 commands and no insertion cursor will be displayed, even if the input
365 focus is in the widget. Also, all insert or delete methods will be
366 ignored. Defaults to normal .
367 Switch: -titlecols
369 Name: titleCols
370 Class: TitleCols
371 Number of columns to use as a title area. Defaults to 0.
372 Switch: -titlerows
374 Name: titleRows
375 Class: TitleRows
376 Number of rows to use as a title area. Defaults to 0.
377 Switch: -usecommand
379 Name: useCommand
380 Class: UseCommand
381 A boolean value which specifies whether to use the command option.
382 This value sets itself to zero if command is used and returns an
383 error. Defaults to 1 (will use command if specified).
384 Switch: -validate
386 Name: validate
387 Class: Validate
388 A boolean specifying whether validation should occur for the active
389 buffer. Defaults to 0.
390 Switch: -validatecommand or -vcmd
392 Name: validateCommand
393 Class: ValidateCommand
394 Specifies a command (callback) to execute when the active cell is
395 edited. This command is expected to return a 1 or 0. If it returns
396 1, then it is assumed the new value is OK, otherwise the new value is
397 rejected (the edition will not take place). Errors in this command
398 are handled in the background. The following arguments are supplied to
399 the callback: row, col, oldContents of cell, potential new contents of
400 cell, Current Index in the cell.
401 Switch: -variable
403 Name: variable
404 Class: Variable
405 Global Tcl array variable to attach to the table's C array. It will
406 be created if it doesn't already exist or is a simple variable. Keys
407 used by the table in the array are of the form row ,col for cells and
408 the special key active which contains the value of the active cell
409 buffer. The Tcl array is managed as a sparse array (the table doesn't
410 require all valid indices have values). No stored value for an index
411 is equivalent to the empty string, and clearing a cell will remove
412 that index from the Tcl array, unless the -sparsearray options is set
413 to 0.
414 Switch: -width
416 Name: width
417 Class: Width
418 Specifies the desired width for the window, in columns. If zero or
419 less, then the desired width for the window is made just large enough
420 to hold all the columns in the table. The width can be further
421 limited by -maxwidth .
422 Switch: -wrap
424 Name: wrap
425 Class: Wrap
426 Specifies the default wrap value for tags. Defaults to 0.
427
429 The TableMatrix command creates a 2-dimensional grid of cells. The
430 table can use a Tcl array variable or Tcl command for data storage and
431 retrieval. The widget has an active cell, the contents of which can be
432 edited (when the state is normal). The widget supports a default style
433 for the cells and also multiple tags , which can be used to change the
434 style of a row, column or cell (see TAGS for details). A cell flash
435 can be set up so that changed cells will change color for a specified
436 amount of time ("blink").
437 Cells can have embedded images or windows, as described in Tags and
438 "Embedded Windows" respectively.
439 One or more cells may be selected as described below.
441 If a table is exporting its selection (see -exportselection option),
442 then it will observe the standard X11 protocols for handling the
443 selection.
444 See "the Selection" for details. It is not necessary for all the cells
445 to be displayed in the table window at once; commands described below
446 may be used to change the view in the window. Tables allow scrolling in
447 both directions using the standard -xscrollcommand and -yscrollcommand
448 options.
449 They also support scanning, as described below.
450 In order to obtain good performance, the table widget supports multiple
452 drawing modes, two of which are fully Tk compatible.
453
455 Many of the widget commands for tables take one or more indices as
456 arguments. An index specifies a particular cell of the table, in any of
457 the following ways:
458 number,number
460 Specifies the cell as a numerical index of row,col which corresponds
461 to the index of the associated Perl Hash, where -roworigin,-colorigin
462 corresponds to the first cell in the table (0,0 by default). The
463 values for row and column will be constrained to actual values in the
464 table, which means a valid cell is always found.
465 active
467 Indicates the cell that has the location cursor. It is specified with
468 the activate widget command.
469 anchor
471 Indicates the anchor point for the selection, which is set with the
472 selection anchor widget command.
473 bottomright
475 Indicates the bottom-rightmost cell visible in the table.
476 end
478 Indicates the bottom right cell of the table.
479 origin
481 Indicates the top-leftmost editable cell of the table, not necessarily
482 in the display. This takes into account the user specified origin and
483 title area.
484 topleft
486 Indicates the top-leftmost editable cell visible in the table (this
487 excludes title cells).
488 @x,y
490 Indicates the cell that covers the point in the table window specified
491 by x and y (in pixel coordinates). If no cell covers that point,
492 then the closest cell to that point is used. In the widget command
493 descriptions below, arguments named index , first , and last always
494 contain text indices in one of the above forms.
495
497 A tag is a textual string that is associated with zero or more rows,
498 columns or cells in a table. Tags may contain arbitrary characters,
499 but it is probably best to avoid using names which look like indices to
500 reduce coding confusion. There may be any number of tags in a table,
501 but each row, column or cell can only have one tag associated with it
502 at a time. There are several permanent tags in each table that can be
503 configured by the user and will determine the attributes for special
504 cells:
505 active
507 This tag is given to the active cell
508 flash
510 If flash mode is on, this tag is given to any recently edited cells.
511 sel
513 This tag is given to any selected cells.
514 title
516 This tag is given to any cells in the title rows and columns. This
517 tag has -state disabled by default.
518 Tags control the way cells are displayed on the screen. Where
520 appropriate, the default for displaying cells is determined by the
521 options for the table widget. However, display options may be
522 associated with individual tags using the tagConfigure method. If a
523 cell, row or column has been tagged, then the display options
524 associated with the tag override the default display style. The
525 following options are currently supported for tags:
526 -anchor anchor
528 Anchor for item in the cell space.
529 -background or -bg color
531 Background color of the cell.
532 -borderwidth or -bd pixel
534 Borderwidth of the cell, of the same format for the table, but may
535 also be empty to inherit the default table borderwidth value (the
536 default).
537 -font fontName
539 Font for text in the cell.
540 -foreground or -fg color
542 Foreground color of the cell.
543 -justify justify
545 How to justify multi-line text in a cell. It must be one of left ,
546 right , or center.
547 -image imageName
549 An image to display in the cell instead of text.
550 -multiline boolean
552 Whether to display text with newlines on multiple lines.
553 -relief
555 The relief for the cell. May be the empty string to cause this tag to
556 not disturb the value.
557 -showtext boolean
559 Whether to show the text over an image.
560 -state state
562 The state of the cell, to allow for certain cells to be disabled. This
563 prevents the cell from being edited by the insert or delete methods,
564 but a direct set will not be prevented.
565 -wrap boolean
567 Whether characters should wrap in a cell that is not wide enough.
568 A priority order is defined among tags based on creation order (first
570 created tag has highest default priority), and this order is used in
571 implementing some of the tag-related functions described below. When a
572 cell is displayed, its properties are determined by the tags which are
573 assigned to it. The priority of a tag can be modified by the tagLower
574 and the tagRaise methods.
575 If a cell has several tags associated with it that define the same
577 display options (eg - a title cell with specific row and cell tags),
578 then the options of the highest priority tag are used. If a particular
579 display option hasn't been specified for a particular tag, or if it is
580 specified as an empty string, then that option will not be used; the
581 next-highest-priority tag's option will be used instead. If no tag
582 specifies a particular display option, then the default style for the
583 widget will be used.
584 Images are used for display purposes only. Editing in that cell will
586 still be enabled and any querying of the cell will show the text value
587 of the cell, regardless of the value of -showtext .
588 Note: There can be only one tag for a given tag type. ( Tag types =
590 flash , active , sel , title , celltag rowtag , coltag .) For example,
591 you can't apply two cell tags to a single cell (or two row tags to a
592 single row, etc) and expect the tag's properties to be merged. The last
593 tag-type applied will be the one that is used.
594
596 There may be any number of embedded windows in a table widget (one per
597 cell), and any widget may be used as an embedded window (subject to the
598 usual rules for geometry management, which require the table window to
599 be the parent of the embedded window or a descendant of its parent).
600 The embedded window's position on the screen will be updated as the
601 table is modified or scrolled, and it will be mapped and unmapped as it
602 moves into and out of the visible area of the table widget. Each
603 embedded window occupies one cell's worth of space in the table widget,
604 and it is referred to by the index of the cell in the table. Windows
605 associated with the table widget are destroyed when the table widget is
606 destroyed.
607 Windows are used for display purposes only. A value still exists for
609 that cell, but will not be shown unless the window is deleted in some
610 way. If the window is destroyed or lost by the table widget to another
611 geometry manager, then any data associated with it is lost (the cell it
612 occupied will no longer appear in window names ).
613 When an embedded window is added to a table widget with the window
615 configure widget command, several configuration options may be
616 associated with it. These options may be modified with later calls to
617 the window configure widget command. The following options are
618 currently supported:
619 -create callback
621 NOT CURRENTLY SUPPORTED. Specifies a Tcl script that may be evaluated
622 to create the window for the annotation.
623 If no -window option has been specified for this cell then this
624 script will be evaluated when the cell is about to be displayed on the
625 screen.
626 Script must create a window for the cell and return the name of that
627 window as its result. If the cell's window should ever be deleted, the
628 script will be evaluated again the next time the cell is displayed.
629 -background or -bg color
631 Background color of the cell. If not specified, it uses the table's
632 default background.
633 -borderwidth or -bd pixelList
635 Borderwidth of the cell, of the same format for the table, but may
636 also be empty to inherit the default table borderwidth value (the
637 default).
638 -padx pixels
640 As defined in the Tk options man page.
641 -pady pixels
643 As defined in the Tk options man page.
644 -relief relief
646 The relief to use for the cell in which the window lies. If not
647 specified, it uses the table's default relief.
648 -sticky sticky
650 Stickiness of the window inside the cell, as defined by the grid
651 command.
652 -window $widget
654 Specifies the a window to display in the annotation. It must exist
655 before being specified here.
656
658 Table selections are available as type STRING. By default, the value
659 of the selection will be the values of the selected cells in nested Tcl
660 list form where each row is a list and each column is an element of a
661 row list. You can change the way this value is interpreted by setting
662 the -rowseparator and -colseparator options.
663 For example, default Excel format would be to set -rowseparator to
664 "\n" and -colseparator to "\t". Changing these values affects both
665 how the table sends out the selection and reads in pasted data,
666 ensuring that the table should always be able to cut and paste to
667 itself. It is possible to change how pastes are handled by editing the
668 table library procedure tk_tablePasteHandler . This might be necessary
669 if -selectioncommand is set.
670
672 Individual cells can span multiple rows and/or columns. This is done
673 via the spans command (see below for exact arguments). Cells in the
674 title area that span are not permitted to span beyond the title area,
675 and will be constrained accordingly. If the title area shrinks during
676 a configure, sanity checking will occur to ensure the above. You may
677 set spans on regular cells that extend beyond the defined row/col area.
678 These spans will not be constrained, so that when the defined row/col
679 area expands, the span will expand with it.
680 When setting a span, checks are made as to whether the span would
682 overlap an already spanning or hidden cell. This is an error and it
683 not allowed. Spans can affect the overall speed of table drawing,
684 although not significantly. If spans are not used, then there is no
685 performance loss.
686 Cells hidden by spanning cells still have valid data. This will be
688 seen during cut and paste operations that involve hidden cells, or
689 through direct access by a command like get or set .
690 The drawing properties of spanning cells apply to only the visual area
692 of the cell. For example, if a cell is center justified over 5
693 columns, then when viewing any portion of those columns, it will appear
694 centered in the visible area. The non-visible column area will not be
695 considered in the centering calculations.
696
698 The various option based commands that the table supports all support
699 the familiar Tk %-substitution model (see "Tk::bind " for more
700 details).
701 The following %-sequences are recognized and substituted by the table
702 widget:
703 %c
705 For SelectionCommand , it is the maximum number of columns in any row
706 in the selection. Otherwise it is the column of the triggered cell.
707 %C
709 A convenience substitution for %r ,%c .
710 %i
712 For SelectionCommand, it is the total number of cells in the
713 selection. For Command , it is 0 for a read (get) and 1 for a write
714 (set). Otherwise it is the current cursor position in the cell.
715 %r
717 For SelectionCommand , it is the number of rows in the selection.
718 Otherwise it is the row of the triggered cell.
719 %s
721 For ValidateCommand , it is the current value of the cell being
722 validated. For SelectionCommand , it is the default value of the
723 selection. For BrowseCommand , it is the index of the last active
724 cell. For Command , it is empty for reads (get) and the current value
725 of the cell for writes (set).
726 %S
728 For ValidateCommand , it is the potential new value of the cell being
729 validated. For BrowseCommand , it is the index of the new active
730 cell.
731 %W
733 The pathname to the window for which the command was generated.
734
736 The $window->TableMatrix method creates a widget object. This object
737 supports the configure and cget methods described in Tk::options which
738 can be used to enquire and modify the options described above. The
739 widget also inherits all the methods provided by the generic Tk::Widget
740 class.
741 The following additional methods are available for scale widgets:
743 $table->activate(index)
745 Sets the active cell to the one indicated by index.
746 $table->bbox(first, ?last?)
748 It returns the bounding box for the specified cell (range) as a
749 4-tuple of x, y, width and height in pixels. It clips the box to the
750 visible portion, if any, otherwise an empty string is returned.
751 $table->border(option, args)
753 This command is a voodoo hack to implement border sizing for tables.
754 This is normally called through bindings, with the following as valid
755 options:
756 $table->borderMark(x, y, ?row|col?)
758 Records x and y and the row and/or column border under that point
759 in the table window, if any; used in conjunction with later border
760 dragto commands. Typically this command is associated with a mouse
761 button press in the widget. If row or col is not specified, it
762 returns a tuple of both border indices (an empty item means no
763 border). Otherwise, just the specified item is returned.
764 $table->borderDragto(x, y)
766 This command computes the difference between its x and y arguments
767 and the x and y arguments to the last border mark command for the
768 widget. It then adjusts the previously marked border by the
769 difference. This command is typically associated with mouse motion
770 events in the widget, to produce the effect of interactive border
771 resizing.
772 $table->cget(option)
774 Returns the current value of the configuration option given by option
775 . Option may have any of the values accepted by the table command.
776 $table->clear(option, ?first?, ?last?)
778 This command is a convenience routine to clear certain state
779 information managed by the table. first and last represent valid
780 table indices. If neither are specified, then the command operates on
781 the whole table. The following options are recognized:
782 $table->clearCache(?first?, ?last?)
784 Clears the specified section of the cache, if the table has been
785 keeping one.
786 $table->clearSizes(?first?, ?last?)
788 Clears the specified row and column areas of specific height/width
789 dimensions. When just one index is specified, for example 2,0 , that
790 is interpreted as row 2 and column 0.
791 $table->clearTags(?first?, ?last?)
793 Clears the specified area of tags (all row, column and cell tags).
794 $table->clearAll(?first?, ?last?)
796 Performs all of the above clear functions on the specified area.
797 $table->colWidth(?col?, ?value, col, value, ...?)
799 If no col is specified, returns a list describing all cols for which
800 a width has been set. If col is specified with no value, it prints
801 out the width of that col in characters (positive number) or pixels
802 (negative number). If one or more col-value pairs are specified,
803 then it sets each col to be that width in characters (positive number)
804 or pixels (negative number). If value is default , then the col uses
805 the default width, specified by -colwidth .
806 $table->configure(?option?, ?value, option, value, ...?)
808 Query or modify the configuration options of the widget. If no option
809 is specified, returns a list describing all of the available options
810 for pathName (see Tk_ConfigureInfo for information on the format of
811 this list). If option is specified with no value , then the command
812 returns a list describing the one named option (this list will be
813 identical to the corresponding sublist of the value returned if no
814 option is specified). If one or more option-value pairs are
815 specified, then the command modifies the given widget option(s) to
816 have the given value(s); in this case the command returns an empty
817 string. Option may have any of the values accepted by the table
818 command.
819 $table->curselection(?value?)
821 With no arguments, it returns the sorted indices of the currently
822 selected cells. Otherwise it sets all the selected cells to the
823 given value. The set has no effect if there is no associated Tcl
824 array or the state is disabled.
825 $table->curvalue(?value?)
827 If no value is given, the value of the cell being edited (indexed by
828 active ) is returned, else it is set to the given value.
829 $table->delete(option, arg, ?arg?)
831 This command is used to delete various things in a table. It has
832 several forms, depending on the option :
833 $table->deleteActive(index, ?index?)
835 Deletes text from the active cell. If only one index is given, it
836 deletes the character after that index, otherwise it deletes from
837 the first index to the second. index can be a number, insert or
838 end .
839 $table->deleteCols(?switches?, index, ?count?)
841 Deletes count cols starting at (and including) col index . The
842 index will be constrained to the limits of the tables. If count
843 is negative, it deletes cols to the left. Otherwise it deletes cols
844 to the right. count defaults to 1 (meaning just the column
845 specified). The selection will be cleared. At the moment, spans
846 are not adjusted with this action. Optional switches are:
847 -holddimensions
849 Causes the table cols to be unaffected by the deletion (empty cols
850 may appear).
851 By default the dimensions are adjusted by count .
852 -holdtags
854 Causes the tags specified by the tag method to not move along with
855 the data. Also prevents specific widths set by the width method
856 from being adjusted.
857 By default, these tags are properly adjusted.
858 -holdwindows
860 Causes the embedded windows created with the window method to not
861 move along with the data. By default, these windows are properly
862 adjusted.
863 -keeptitles
865 Prevents title area cells from being changed. Otherwise they are
866 treated just like regular cells and will move as specified.
867 $table->deleteRows(?switches?, index, ?count?)
869 Deletes count rows starting at (and including) row index . If
870 count is negative, it deletes rows going up. Otherwise it deletes
871 rows going down. The selection will be cleared. The switches are
872 the same as those for column deletion.
873 $table->get(first, ?last?)
875 Returns the value of the cells specified by the table indices first
876 and (optionally) last in a list.
877 $table->hidden(?index?, ?index, ...?)
879 When called without args, it returns all the hidden cells (those
880 cells covered by a spanning cell). If one index is specified, it
881 returns the spanning cell covering that index, if any. If multiple
882 indices are specified, it returns 1 if all indices are hidden cells,
883 0 otherwise.
884 $table->icursor(?arg?)
886 With no arguments, prints out the location of the insertion cursor in
887 the active cell. With one argument, sets the cursor to that point in
888 the string. 0 is before the first character, you can also use insert
889 or end for the current insertion point or the end of the text. If
890 there is no active cell, or the cell or table is disabled, this will
891 return -1.
892 $table->index(index, ?row|col?)
894 Returns the integer cell coordinate that corresponds to index in the
895 form row,col. If row or col is specified, then only the row or
896 column index is returned.
897 $table->insert(option, arg, arg)
899 This command is used to into various things into a table. It has
900 several forms, depending on the option :
901 $table->insertActive(index, value)
903 The value is a text string which is inserted at the index postion
904 of the active cell. The cursor is then positioned after the new
905 text. index can be a number, insert or end .
906 $table->insertCols(?switches?, index, ?count?)
908 Inserts count cols starting at col index . If count is negative,
909 it inserts before the specified col. Otherwise it inserts after the
910 specified col. The selection will be cleared. The switches are the
911 same as those for column deletion.
912 $table->insertRows(?switches?, index, ?count?)
914 Inserts count rows starting at row index . If count is negative,
915 it inserts before the specified row. Otherwise it inserts after the
916 specified row. The selection will be cleared. The switches are the
917 same as those for column deletion.
918 $table->reread()
920 Rereads the old contents of the cell back into the editing buffer.
921 Useful for a key binding when <Escape> is pressed to abort the edit
922 (a default binding).
923 $table->rowHeight(?row?, ?value, row, value, ...?)
925 If no row is specified, returns a list describing all rows for which
926 a height has been set. If row is specified with no value, it prints
927 out the height of that row in characters (positive number) or pixels
928 (negative number). If one or more row-value pairs are specified,
929 then it sets each row to be that height in lines (positive number) or
930 pixels (negative number). If value is default , then the row uses
931 the default height, specified by -rowheight .
932 $table->scan(option, args)
934 This command is used to implement scanning on tables. It has two
935 forms, depending on option :
936 $table->scanMark(x, y)
938 Records x and y and the current view in the table window;
939 used in conjunction with later scan dragto commands. Typically
940 this command is associated with a mouse button press in the widget.
941 It returns an empty string.
942 $table->scanDragto(x, y.)
944 This command computes the difference between its x and y arguments
945 and the x and y arguments to the last scan mark command for the
946 widget. It then adjusts the view by 5 times the difference in
947 coordinates. This command is typically associated with mouse motion
948 events in the widget, to produce the effect of dragging the list at
949 high speed through the window. The return value is an empty string.
950 $table->see(index)
952 Adjust the view in the table so that the cell given by index is
953 positioned as the cell one off from top left (excluding title rows
954 and columns) if the cell is not currently visible on the screen. The
955 actual cell may be different to keep the screen full.
956 $table->selection(option, arg)
958 This command is used to adjust the selection within a table.
959 It has several forms, depending on option :
960 $table->selectionAnchor(index)
962 Sets the selection anchor to the cell given by index . The
963 selection anchor is the end of the selection that is fixed while
964 dragging out a selection with the mouse. The index anchor may be
965 used to refer to the anchor cell.
966 $table->selectionClear(first?last?)
968 If any of the cells between first and last (inclusive) are
969 selected, they are deselected.
970 The selection state is not changed for cells outside this range.
971 first may be specified as all to remove the selection from all
972 cells.
973 $table->selectionIncludes(index)
975 Returns 1 if the cell indicated by index is currently selected, 0 if
976 it isn't.
977 $table->selectionSet(first, ?last?)
979 Selects all of the cells in the range between first and last ,
980 inclusive, without affecting the selection state of cells outside
981 that range.
982 perltk note this needs to be perlized
984 $table->set(?row|col?, index, ?value?, ?index, value, ...?)
986 Sets the specified index to the associated value. Table validation
988 will not be triggered via this method. If row or col precedes the
989 list of index/value pairs, then the value is assumed to be a Tcl list
990 whose values will be split and set into the subsequent columns (if
991 row is specified) or rows (for col ). For example, set row 2,3
992 {2,3 2,4 2,5} will set 3 cells, from 2,3 to 2,5. The setting of
993 cells is silently bounded by the known table dimensions.
994 $table->spans(?index?, ?rows,cols, index, rows,cols, ...?)
996 This command is used to manipulate row/col spans. When called with
998 no arguments, all known spans are returned as a list of tuples of the
999 form {index span}. When called with only the index , the span for
1000 that index only is returned, if any. Otherwise an even number of
1001 index rows,cols pairs are used to set spans. A span starts at the
1002 index and continues for the specified number of rows and cols.
1003 Negative spans are not supported. A span of 0,0 unsets any span on
1004 that cell. See EXAMPLES for more info.
1005 $table->tag(option, ?arg, arg, ...?)
1007 This command is used to manipulate tags. The exact behavior of the
1009 command depends on the option argument that follows the tag
1010 argument. cget , cell , and row|col complain about unknown tag
1011 names. The following forms of the command are currently supported:
1012 $table->tagCell(tagName, ?index, ...?)
1014 With no arguments, prints out the list of cells that use the tag.
1015 Otherwise it sets the specified cells to use the named tag,
1016 replacing any tag that may have been set using this method before.
1017 If tagName is '', the cells are reset to the default tag. Tags
1018 added during -*tagcommand evaluation do not register here. If
1019 tagName does not exist, it will be created with the default options.
1020 $table->tagCget(tagName, option)
1022 This command returns the current value of the option named option
1023 associated with the tag given by tagName . Option may have any of
1024 the values accepted by the tag configure widget command.
1025 $table->tagCol(tagName, ?col, ...?)
1027 With no arguments, prints out the list of cols that use the tag.
1028 Otherwise it sets the specified columns to use the named tag,
1029 replacing any tag that may have been set using this method before.
1030 If <tagName> is '', the cols are reset to the default tag. Tags
1031 added during -coltagcommand evaluation do not register here. If
1032 tagName does not exist, it will be created with the default options.
1033 $table->tagConfigure(tagName, ?option?, ?value?, ?option, value, ...?)
1035 This command is similar to the configure widget command except that
1036 it modifies options associated with the tag given by tagName
1037 instead of modifying options for the overall table widget. If no
1038 option is specified, the command returns a list describing all of
1039 the available options for tagName (see Tk_ConfigureInfo for
1040 information on the format of this list). If option is specified
1041 with no value , then the command returns a list describing the one
1042 named option (this list will be identical to the corresponding
1043 sublist of the value returned if no option is specified). If one
1044 or more option-value pairs are specified, then the command modifies
1045 the given option(s) to have the given value(s) in tagName ; in this
1046 case the command returns an empty string. See TAGS above for details
1047 on the options available for tags.
1048 $table->tagDelete(tagName)
1050 Deletes a tag. No error if the tag does not exist.
1051 $table->tagExists(tagName)
1053 Returns 1 if the named tag exists, 0 otherwise.
1054 $table->tagIncludes(tagName, index)
1056 Returns 1 if the specified index has the named tag, 0 otherwise.
1057 $table->tagLower(tagName, ?belowThis?)
1059 Lower the priority of the named tag. If belowThis is not specified,
1060 then the tag's priority is lowered to the bottom, otherwise it is
1061 lowered to one below belowThis.
1062 $table->tagNames(?pattern?)
1064 If no pattern is specified, shows the names of all defined tags.
1065 Otherwise the pattern is used as a glob pattern to show only tags
1066 matching that pattern. Tag names are returned in priority order
1067 (highest priority tag first).
1068 $table->tagRaise(tagName, ?aboveThis?)
1070 Raise the priority of the named tag. If aboveThis is not specified,
1071 then the tag's priority is raised to the top, otherwise it is raised
1072 to one above aboveThis.
1073 $table->tagRow(tagName, ?row, ...?)
1075 With no arguments, prints out the list of rows that use the tag.
1076 Otherwise it sets the specified columns to use the named tag,
1077 replacing any tag that may have been set using this method before.
1078 If tagName is '', the rows are reset to use the default tag. Tags
1079 added during -rowtagcommand evaluation do not register here. If
1080 tagName does not exist, it will be created with the default options.
1081 $table->validate(index)
1083 Explicitly validates the specified index based on the current
1084 -validatecommand and returns 0 or 1 based on whether the cell was
1085 validated.
1086 $table->window(option, ?arg, arg, ...?)
1088 This command is used to manipulate embedded windows. The exact
1089 behavior of the command depends on the option argument that follows
1090 the window argument. The following forms of the command are
1091 currently supported:
1092 $table->windowCget(index, option)
1094 This command returns the current value of the option named option
1095 associated with the window given by index . Option may have any of
1096 the values accepted by the window configure widget command.
1097 $table->windowConfigure(index, ?option?, ?value?, ?option, value,
1099 ...?)
1100 This command is similar to the configure widget command except that
1101 it modifies options associated with the embedded window given by
1102 index instead of modifying options for the overall table widget.
1103 If no option is specified, the command returns a list describing
1104 all of the available options for index (see Tk_ConfigureInfo for
1105 information on the format of this list). If option is specified
1106 with no value , then the command returns a list describing the one
1107 named option (this list will be identical to the corresponding
1108 sublist of the value returned if no option is specified). If one
1109 or more option-value pairs are specified, then the command modifies
1110 the given option(s) to have the given value(s) in index ; in this
1111 case the command returns an empty string. See EMBEDDED WINDOWS above
1112 for details on the options available for windows.
1113 $table->windowDelete(index, ?index, ...?)
1115 Deletes an embedded window from the table. The associated window
1116 will also be deleted.
1117 $table->windowMove(indexFrom, indexTo)
1119 Moves an embedded window from one cell to another. If a window
1120 already exists in the target cell, it will be deleted.
1121 $table->windowNames(?pattern?)
1123 If no pattern is specified, shows the cells of all embedded windows.
1124 Otherwise the pattern is used as a glob pattern to show only cells
1125 matching that pattern.
1126 $table->xview(args)
1128 This command is used to query and change the horizontal position of
1129 the information in the widget's window. It can take any of the
1130 following forms:
1131 $table->xview()
1133 Returns a list containing two elements. Each element is a real
1134 fraction between 0 and 1; together they describe the horizontal span
1135 that is visible in the window. For example, if the first element is
1136 .2 and the second element is .6, 20% of the table's text is off-
1137 screen to the left, the middle 40% is visible in the window, and 40%
1138 of the text is off-screen to the right. These are the same values
1139 passed to scrollbars via the -xscrollcommand option.
1140 $table->xview(index)
1142 Adjusts the view in the window so that the column given by index is
1143 displayed at the left edge of the window.
1144 $table->xviewMoveto(fraction)
1146 Adjusts the view in the window so that fraction of the total width
1147 of the table text is off-screen to the left. fraction must be a
1148 fraction between 0 and 1.
1149 $table->xviewScroll(number, what)
1151 This command shifts the view in the window left or right according to
1152 number and what . Number must be an integer. What must be either
1153 units or pages or an abbreviation of one of these. If what is
1154 units , the view adjusts left or right by number cells on the
1155 display; if it is pages then the view adjusts by number
1156 screenfuls. If number is negative then cells farther to the left
1157 become visible; if it is positive then cells farther to the right
1158 become visible.
1159 $table->yview(?args?)
1161 This command is used to query and change the vertical position of the
1162 text in the widget's window. It can take any of the following forms:
1163 $table->yview()
1165 Returns a list containing two elements, both of which are real
1166 fractions between 0 and 1. The first element gives the position of
1167 the table element at the top of the window, relative to the table as
1168 a whole (0.5 means it is halfway through the table, for example).
1169 The second element gives the position of the table element just
1170 after the last one in the window, relative to the table as a whole.
1171 These are the same values passed to scrollbars via the
1172 -yscrollcommand option.
1173 $table->yview(index)
1175 Adjusts the view in the window so that the row given by index is
1176 displayed at the top of the window.
1177 $table->yviewMoveto(fraction)
1179 Adjusts the view in the window so that the element given by fraction
1180 appears at the top of the window. Fraction is a fraction between 0
1181 and 1; 0 indicates the first element in the table, 0.33 indicates
1182 the element one-third the way through the table, and so on.
1183 $table->yviewscroll(number, what)
1185 This command adjusts the view in the window up or down according to
1186 number and what . Number must be an integer. What must be
1187 either units or pages . If what is units , the view adjusts up or
1188 down by number cells; if it is pages then the view adjusts by
1189 number screenfuls. If number is negative then earlier elements
1190 become visible; if it is positive then later elements become
1191 visible.
1192
1194 The initialization creates class bindings that give the following
1195 default behaviour:
1196 [1]
1198 Clicking Button-1 in a cell activates that cell. Clicking into an
1199 already active cell moves the insertion cursor to the character
1200 nearest the mouse.

1203 Moving the mouse while Button-1 is pressed will stroke out a selection
1204 area. Exiting while Button-1 is pressed causing scanning to occur on
1205 the table along with selection.
1206 [3]
1208 Moving the mouse while Button-2 is pressed causes scanning to occur
1209 without any selection.
1210 [4]
1212 Home moves the table to have the origin in view.
1213 [5]
1215 End moves the table to have the end cell in view.
1216 [6]
1218 Control-Home moves the table to the origin and activates that cell.
1219 [7]
1221 Control-End moves the table to the end and activates that cell.
1222 [8]
1224 Shift-Control-Home extends the selection to the origin.
1225 [9]
1227 Shift-Control-End extends the selection to the end.
1228 [10]
1230 The left, right, up and down arrows move the active cell.
1231 [11]
1233 Shift-<arrow> extends the selection in that direction.
1234 [12]
1236 Control-leftarrow and Control-rightarrow move the insertion cursor
1237 within the cell.
1238 [13]
1240 Control-slash selects all the cells.
1241 [14]
1243 Control-backslash clears selection from all the cells.
1244 [15]
1246 Backspace deletes the character before the insertion cursor in the
1247 active cell.
1248 [16]
1250 Delete deletes the character after the insertion cursor in the active
1251 cell.
1252 [17]
1254 Escape rereads the value of the active cell from the specified data
1255 source, discarding any edits that have may been performed on the cell.
1256 [18]
1258 Control-a moves the insertion cursor to the beginning of the active
1259 cell.
1260 [19]
1262 Control-e moves the insertion cursor to the end of the active cell.
1263 [20]
1265 Control-minus and Control-equals decrease and increase the width of
1266 the column with the active cell in it.
1267 [21]
1269 Moving the mouse while Button-3 (the right button on Windows) is
1270 pressed while you are over a border will cause interactive resizing of
1271 that row and/or column to occur, based on the value of -resizeborders
1272 . Some bindings may have slightly different behavior dependent on the
1273 -selectionmode of the widget. If the widget is disabled using the
1274 -state option, then its view can still be adjusted and cells can
1275 still be selected, but no insertion cursor will be displayed and no
1276 cell modifications will take place. The behavior of tables can be
1277 changed by defining new bindings for individual widgets or by
1278 redefining the class bindings. The default bindings are either
1279 compiled in the TableMatrix.pm file
1280
1282 The number of rows and columns or a table widget should not
1283 significantly affect the speed of redraw. Recalculation and redraw of
1284 table parameters and cells is restricted as much as possible. The
1285 display cell with the insert cursor is redrawn each time the cursor
1286 blinks, which causes a steady stream of graphics traffic. Set the
1287 -insertofftime option to 0 avoid this. The use of a -command with the
1288 table without a cache can cause significant slow-down, as the command
1289 is called once for each request of a cell value.
1290
1292 Set the topleft title area to be one spanning cell. This overestimates
1293 both row and column span by one, but the command does all the
1294 constraining for us. $table span [$table cget -roworigin],[$table cget
1295 -colorigin] [$table cget -titlerows],[$table cget -titlecols] Force a
1296 table window refresh (useful for the slight chance that a bug in the
1297 table is not causing proper refresh): $table configure -padx [$table
1298 cget -padx]
