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 for
179 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 to
186 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 entire
347 row/col is affected when a cell's selection is changed (set or clear).
348 Switch: -sparsearray
350 Name: sparseArray
351 Class: SparseArray
352 A boolean value that specifies whether an associated Tcl array should
353 be kept as a sparse array (1, the default) or as a full array (0). If
354 true, then cell values that are empty will be deleted from the array
355 (taking less memory). If false, then all values in the array will be
356 maintained.
357 Switch: -state
359 Name: state
360 Class: State
361 Specifies one of two states for the entry: normal or disabled. If
362 the table is disabled then the value may not be changed using widget
363 commands and no insertion cursor will be displayed, even if the input
364 focus is in the widget. Also, all insert or delete methods will be
365 ignored. Defaults to normal.
366 Switch: -titlecols
368 Name: titleCols
369 Class: TitleCols
370 Number of columns to use as a title area. Defaults to 0.
371 Switch: -titlerows
373 Name: titleRows
374 Class: TitleRows
375 Number of rows to use as a title area. Defaults to 0.
376 Switch: -usecommand
378 Name: useCommand
379 Class: UseCommand
380 A boolean value which specifies whether to use the command option.
381 This value sets itself to zero if command is used and returns an
382 error. Defaults to 1 (will use command if specified).
383 Switch: -validate
385 Name: validate
386 Class: Validate
387 A boolean specifying whether validation should occur for the active
388 buffer. Defaults to 0.
389 Switch: -validatecommand or -vcmd
391 Name: validateCommand
392 Class: ValidateCommand
393 Specifies a command (callback) to execute when the active cell is
394 edited. This command is expected to return a 1 or 0. If it returns
395 1, then it is assumed the new value is OK, otherwise the new value is
396 rejected (the edition will not take place). Errors in this command
397 are handled in the background. The following arguments are supplied to
398 the callback: row, col, oldContents of cell, potential new contents of
399 cell, Current Index in the cell.
400 Switch: -variable
402 Name: variable
403 Class: Variable
404 Global Tcl array variable to attach to the table's C array. It will
405 be created if it doesn't already exist or is a simple variable. Keys
406 used by the table in the array are of the form row,col for cells and
407 the special key active which contains the value of the active cell
408 buffer. The Tcl array is managed as a sparse array (the table doesn't
409 require all valid indices have values). No stored value for an index
410 is equivalent to the empty string, and clearing a cell will remove
411 that index from the Tcl array, unless the -sparsearray options is set
412 to 0.
413 Switch: -width
415 Name: width
416 Class: Width
417 Specifies the desired width for the window, in columns. If zero or
418 less, then the desired width for the window is made just large enough
419 to hold all the columns in the table. The width can be further
420 limited by -maxwidth.
421 Switch: -wrap
423 Name: wrap
424 Class: Wrap
425 Specifies the default wrap value for tags. Defaults to 0.
426
428 The TableMatrix command creates a 2-dimensional grid of cells. The
429 table can use a Tcl array variable or Tcl command for data storage and
430 retrieval. The widget has an active cell, the contents of which can be
431 edited (when the state is normal). The widget supports a default style
432 for the cells and also multiple tags, which can be used to change the
433 style of a row, column or cell (see TAGS for details). A cell flash
434 can be set up so that changed cells will change color for a specified
435 amount of time ("blink").
436 Cells can have embedded images or windows, as described in Tags and
437 "Embedded Windows" respectively.
438 One or more cells may be selected as described below.
440 If a table is exporting its selection (see -exportselection option),
441 then it will observe the standard X11 protocols for handling the
442 selection.
443 See "the Selection" for details. It is not necessary for all the cells
444 to be displayed in the table window at once; commands described below
445 may be used to change the view in the window. Tables allow scrolling in
446 both directions using the standard -xscrollcommand and -yscrollcommand
447 options.
448 They also support scanning, as described below.
449 In order to obtain good performance, the table widget supports multiple
451 drawing modes, two of which are fully Tk compatible.
452
454 Many of the widget commands for tables take one or more indices as
455 arguments. An index specifies a particular cell of the table, in any of
456 the following ways:
457 number,number
459 Specifies the cell as a numerical index of row,col which corresponds
460 to the index of the associated Perl Hash, where -roworigin,-colorigin
461 corresponds to the first cell in the table (0,0 by default). The
462 values for row and column will be constrained to actual values in the
463 table, which means a valid cell is always found.
464 active
466 Indicates the cell that has the location cursor. It is specified with
467 the activate widget command.
468 anchor
470 Indicates the anchor point for the selection, which is set with the
471 selection anchor widget command.
472 bottomright
474 Indicates the bottom-rightmost cell visible in the table.
475 end
477 Indicates the bottom right cell of the table.
478 origin
480 Indicates the top-leftmost editable cell of the table, not necessarily
481 in the display. This takes into account the user specified origin and
482 title area.
483 topleft
485 Indicates the top-leftmost editable cell visible in the table (this
486 excludes title cells).
487 @x,y
489 Indicates the cell that covers the point in the table window specified
490 by x and y (in pixel coordinates). If no cell covers that point, then
491 the closest cell to that point is used. In the widget command
492 descriptions below, arguments named index, first, and last always
493 contain text indices in one of the above forms.
494
496 A tag is a textual string that is associated with zero or more rows,
497 columns or cells in a table. Tags may contain arbitrary characters,
498 but it is probably best to avoid using names which look like indices to
499 reduce coding confusion. There may be any number of tags in a table,
500 but each row, column or cell can only have one tag associated with it
501 at a time. There are several permanent tags in each table that can be
502 configured by the user and will determine the attributes for special
503 cells:
504 active
506 This tag is given to the active cell
507 flash
509 If flash mode is on, this tag is given to any recently edited cells.
510 sel
512 This tag is given to any selected cells.
513 title
515 This tag is given to any cells in the title rows and columns. This
516 tag has -state disabled by default.
517 Tags control the way cells are displayed on the screen. Where
519 appropriate, the default for displaying cells is determined by the
520 options for the table widget. However, display options may be
521 associated with individual tags using the tagConfigure method. If a
522 cell, row or column has been tagged, then the display options
523 associated with the tag override the default display style. The
524 following options are currently supported for tags:
525 -anchor anchor
527 Anchor for item in the cell space.
528 -background or -bg color
530 Background color of the cell.
531 -borderwidth or -bd pixel
533 Borderwidth of the cell, of the same format for the table, but may
534 also be empty to inherit the default table borderwidth value (the
535 default).
536 -font fontName
538 Font for text in the cell.
539 -foreground or -fg color
541 Foreground color of the cell.
542 -justify justify
544 How to justify multi-line text in a cell. It must be one of left,
545 right, or center.
546 -image imageName
548 An image to display in the cell instead of text.
549 -multiline boolean
551 Whether to display text with newlines on multiple lines.
552 -relief
554 The relief for the cell. May be the empty string to cause this tag to
555 not disturb the value.
556 -showtext boolean
558 Whether to show the text over an image.
559 -state state
561 The state of the cell, to allow for certain cells to be disabled. This
562 prevents the cell from being edited by the insert or delete methods,
563 but a direct set will not be prevented.
564 -wrap boolean
566 Whether characters should wrap in a cell that is not wide enough.
567 A priority order is defined among tags based on creation order (first
569 created tag has highest default priority), and this order is used in
570 implementing some of the tag-related functions described below. When a
571 cell is displayed, its properties are determined by the tags which are
572 assigned to it. The priority of a tag can be modified by the tagLower
573 and the tagRaise methods.
574 If a cell has several tags associated with it that define the same
576 display options (eg - a title cell with specific row and cell tags),
577 then the options of the highest priority tag are used. If a particular
578 display option hasn't been specified for a particular tag, or if it is
579 specified as an empty string, then that option will not be used; the
580 next-highest-priority tag's option will be used instead. If no tag
581 specifies a particular display option, then the default style for the
582 widget will be used.
583 Images are used for display purposes only. Editing in that cell will
585 still be enabled and any querying of the cell will show the text value
586 of the cell, regardless of the value of -showtext.
587 Note: There can be only one tag for a given tag type. ( Tag types =
589 flash, active, sel, title, celltag rowtag, coltag.) For example, you
590 can't apply two cell tags to a single cell (or two row tags to a single
591 row, etc) and expect the tag's properties to be merged. The last tag-
592 type applied will be the one that is used.
593
595 There may be any number of embedded windows in a table widget (one per
596 cell), and any widget may be used as an embedded window (subject to the
597 usual rules for geometry management, which require the table window to
598 be the parent of the embedded window or a descendant of its parent).
599 The embedded window's position on the screen will be updated as the
600 table is modified or scrolled, and it will be mapped and unmapped as it
601 moves into and out of the visible area of the table widget. Each
602 embedded window occupies one cell's worth of space in the table widget,
603 and it is referred to by the index of the cell in the table. Windows
604 associated with the table widget are destroyed when the table widget is
605 destroyed.
606 Windows are used for display purposes only. A value still exists for
608 that cell, but will not be shown unless the window is deleted in some
609 way. If the window is destroyed or lost by the table widget to another
610 geometry manager, then any data associated with it is lost (the cell it
611 occupied will no longer appear in window names).
612 When an embedded window is added to a table widget with the window
614 configure widget command, several configuration options may be
615 associated with it. These options may be modified with later calls to
616 the window configure widget command. The following options are
617 currently supported:
618 -create callback
620 NOT CURRENTLY SUPPORTED. Specifies a Tcl script that may be evaluated
621 to create the window for the annotation.
622 If no -window option has been specified for this cell then this
623 script will be evaluated when the cell is about to be displayed on the
624 screen.
625 Script must create a window for the cell and return the name of that
626 window as its result. If the cell's window should ever be deleted, the
627 script will be evaluated again the next time the cell is displayed.
628 -background or -bg color
630 Background color of the cell. If not specified, it uses the table's
631 default background.
632 -borderwidth or -bd pixelList
634 Borderwidth of the cell, of the same format for the table, but may
635 also be empty to inherit the default table borderwidth value (the
636 default).
637 -padx pixels
639 As defined in the Tk options man page.
640 -pady pixels
642 As defined in the Tk options man page.
643 -relief relief
645 The relief to use for the cell in which the window lies. If not
646 specified, it uses the table's default relief.
647 -sticky sticky
649 Stickiness of the window inside the cell, as defined by the grid
650 command.
651 -window $widget
653 Specifies the a window to display in the annotation. It must exist
654 before being specified here.
655
657 Table selections are available as type STRING. By default, the value
658 of the selection will be the values of the selected cells in nested Tcl
659 list form where each row is a list and each column is an element of a
660 row list. You can change the way this value is interpreted by setting
661 the -rowseparator and -colseparator options.
662 For example, default Excel format would be to set -rowseparator to
663 "\n" and -colseparator to "\t". Changing these values affects both how
664 the table sends out the selection and reads in pasted data, ensuring
665 that the table should always be able to cut and paste to itself. It is
666 possible to change how pastes are handled by editing the table library
667 procedure tk_tablePasteHandler . This might be necessary if
668 -selectioncommand is set.
669
671 Individual cells can span multiple rows and/or columns. This is done
672 via the spans command (see below for exact arguments). Cells in the
673 title area that span are not permitted to span beyond the title area,
674 and will be constrained accordingly. If the title area shrinks during
675 a configure, sanity checking will occur to ensure the above. You may
676 set spans on regular cells that extend beyond the defined row/col area.
677 These spans will not be constrained, so that when the defined row/col
678 area expands, the span will expand with it.
679 When setting a span, checks are made as to whether the span would
681 overlap an already spanning or hidden cell. This is an error and it
682 not allowed. Spans can affect the overall speed of table drawing,
683 although not significantly. If spans are not used, then there is no
684 performance loss.
685 Cells hidden by spanning cells still have valid data. This will be
687 seen during cut and paste operations that involve hidden cells, or
688 through direct access by a command like get or set.
689 The drawing properties of spanning cells apply to only the visual area
691 of the cell. For example, if a cell is center justified over 5
692 columns, then when viewing any portion of those columns, it will appear
693 centered in the visible area. The non-visible column area will not be
694 considered in the centering calculations.
695
697 The various option based commands that the table supports all support
698 the familiar Tk %-substitution model (see Tk::bind for more details).
699 The following %-sequences are recognized and substituted by the table
700 widget:
701 %c
703 For SelectionCommand, it is the maximum number of columns in any row
704 in the selection. Otherwise it is the column of the triggered cell.
705 %C
707 A convenience substitution for %r,%c.
708 %i
710 For SelectionCommand, it is the total number of cells in the
711 selection. For Command, it is 0 for a read (get) and 1 for a write
712 (set). Otherwise it is the current cursor position in the cell.
713 %r
715 For SelectionCommand, it is the number of rows in the selection.
716 Otherwise it is the row of the triggered cell.
717 %s
719 For ValidateCommand, it is the current value of the cell being
720 validated. For SelectionCommand, it is the default value of the
721 selection. For BrowseCommand , it is the index of the last active
722 cell. For Command, it is empty for reads (get) and the current value
723 of the cell for writes (set).
724 %S
726 For ValidateCommand, it is the potential new value of the cell being
727 validated. For BrowseCommand, it is the index of the new active cell.
728 %W
730 The pathname to the window for which the command was generated.
731
733 The $window->TableMatrix method creates a widget object. This object
734 supports the configure and cget methods described in Tk::options which
735 can be used to enquire and modify the options described above. The
736 widget also inherits all the methods provided by the generic Tk::Widget
737 class.
738 The following additional methods are available for scale widgets:
740 $table->activate(index)
742 Sets the active cell to the one indicated by index.
743 $table->bbox(first, ?last?)
745 It returns the bounding box for the specified cell (range) as a
746 4-tuple of x, y, width and height in pixels. It clips the box to the
747 visible portion, if any, otherwise an empty string is returned.
748 $table->border(option, args)
750 This command is a voodoo hack to implement border sizing for tables.
751 This is normally called through bindings, with the following as valid
752 options:
753 $table->borderMark(x, y, ?row|col?)
755 Records x and y and the row and/or column border under that point in
756 the table window, if any; used in conjunction with later border
757 dragto commands. Typically this command is associated with a mouse
758 button press in the widget. If row or col is not specified, it
759 returns a tuple of both border indices (an empty item means no
760 border). Otherwise, just the specified item is returned.
761 $table->borderDragto(x, y)
763 This command computes the difference between its x and y arguments
764 and the x and y arguments to the last border mark command for the
765 widget. It then adjusts the previously marked border by the
766 difference. This command is typically associated with mouse motion
767 events in the widget, to produce the effect of interactive border
768 resizing.
769 $table->cget(option)
771 Returns the current value of the configuration option given by option.
772 Option may have any of the values accepted by the table command.
773 $table->clear(option, ?first?, ?last?)
775 This command is a convenience routine to clear certain state
776 information managed by the table. first and last represent valid
777 table indices. If neither are specified, then the command operates on
778 the whole table. The following options are recognized:
779 $table->clearCache(?first?, ?last?)
781 Clears the specified section of the cache, if the table has been
782 keeping one.
783 $table->clearSizes(?first?, ?last?)
785 Clears the specified row and column areas of specific height/width
786 dimensions. When just one index is specified, for example 2,0, that
787 is interpreted as row 2 and column 0.
788 $table->clearTags(?first?, ?last?)
790 Clears the specified area of tags (all row, column and cell tags).
791 $table->clearAll(?first?, ?last?)
793 Performs all of the above clear functions on the specified area.
794 $table->colWidth(?col?, ?value, col, value, ...?)
796 If no col is specified, returns a list describing all cols for which a
797 width has been set. If col is specified with no value, it prints out
798 the width of that col in characters (positive number) or pixels
799 (negative number). If one or more col-value pairs are specified, then
800 it sets each col to be that width in characters (positive number) or
801 pixels (negative number). If value is default, then the col uses the
802 default width, specified by -colwidth.
803 $table->configure(?option?, ?value, option, value, ...?)
805 Query or modify the configuration options of the widget. If no option
806 is specified, returns a list describing all of the available options
807 for pathName (see Tk_ConfigureInfo for information on the format of
808 this list). If option is specified with no value, then the command
809 returns a list describing the one named option (this list will be
810 identical to the corresponding sublist of the value returned if no
811 option is specified). If one or more option-value pairs are
812 specified, then the command modifies the given widget option(s) to
813 have the given value(s); in this case the command returns an empty
814 string. Option may have any of the values accepted by the table
815 command.
816 $table->curselection(?value?)
818 With no arguments, it returns the sorted indices of the currently
819 selected cells. Otherwise it sets all the selected cells to the
820 given value. The set has no effect if there is no associated Tcl
821 array or the state is disabled.
822 $table->curvalue(?value?)
824 If no value is given, the value of the cell being edited (indexed by
825 active) is returned, else it is set to the given value.
826 $table->delete(option, arg, ?arg?)
828 This command is used to delete various things in a table. It has
829 several forms, depending on the option:
830 $table->deleteActive(index, ?index?)
832 Deletes text from the active cell. If only one index is given, it
833 deletes the character after that index, otherwise it deletes from
834 the first index to the second. index can be a number, insert or
835 end.
836 $table->deleteCols(?switches?, index, ?count?)
838 Deletes count cols starting at (and including) col index. The index
839 will be constrained to the limits of the tables. If count is
840 negative, it deletes cols to the left. Otherwise it deletes cols to
841 the right. count defaults to 1 (meaning just the column specified).
842 The selection will be cleared. At the moment, spans are not
843 adjusted with this action. Optional switches are:
844 -holddimensions
846 Causes the table cols to be unaffected by the deletion (empty cols
847 may appear).
848 By default the dimensions are adjusted by count.
849 -holdtags
851 Causes the tags specified by the tag method to not move along with
852 the data. Also prevents specific widths set by the width method
853 from being adjusted.
854 By default, these tags are properly adjusted.
855 -holdwindows
857 Causes the embedded windows created with the window method to not
858 move along with the data. By default, these windows are properly
859 adjusted.
860 -keeptitles
862 Prevents title area cells from being changed. Otherwise they are
863 treated just like regular cells and will move as specified.
864 $table->deleteRows(?switches?, index, ?count?)
866 Deletes count rows starting at (and including) row index. If count
867 is negative, it deletes rows going up. Otherwise it deletes rows
868 going down. The selection will be cleared. The switches are the
869 same as those for column deletion.
870 $table->get(first, ?last?)
872 Returns the value of the cells specified by the table indices first
873 and (optionally) last in a list.
874 $table->hidden(?index?, ?index, ...?)
876 When called without args, it returns all the hidden cells (those
877 cells covered by a spanning cell). If one index is specified, it
878 returns the spanning cell covering that index, if any. If multiple
879 indices are specified, it returns 1 if all indices are hidden cells,
880 0 otherwise.
881 $table->icursor(?arg?)
883 With no arguments, prints out the location of the insertion cursor in
884 the active cell. With one argument, sets the cursor to that point in
885 the string. 0 is before the first character, you can also use insert
886 or end for the current insertion point or the end of the text. If
887 there is no active cell, or the cell or table is disabled, this will
888 return -1.
889 $table->index(index, ?row|col?)
891 Returns the integer cell coordinate that corresponds to index in the
892 form row,col. If row or col is specified, then only the row or
893 column index is returned.
894 $table->insert(option, arg, arg)
896 This command is used to into various things into a table. It has
897 several forms, depending on the option:
898 $table->insertActive(index, value)
900 The value is a text string which is inserted at the index postion of
901 the active cell. The cursor is then positioned after the new text.
902 index can be a number, insert or end.
903 $table->insertCols(?switches?, index, ?count?)
905 Inserts count cols starting at col index. If count is negative, it
906 inserts before the specified col. Otherwise it inserts after the
907 specified col. The selection will be cleared. The switches are the
908 same as those for column deletion.
909 $table->insertRows(?switches?, index, ?count?)
911 Inserts count rows starting at row index. If count is negative, it
912 inserts before the specified row. Otherwise it inserts after the
913 specified row. The selection will be cleared. The switches are the
914 same as those for column deletion.
915 $table->reread()
917 Rereads the old contents of the cell back into the editing buffer.
918 Useful for a key binding when <Escape> is pressed to abort the edit
919 (a default binding).
920 $table->rowHeight(?row?, ?value, row, value, ...?)
922 If no row is specified, returns a list describing all rows for which
923 a height has been set. If row is specified with no value, it prints
924 out the height of that row in characters (positive number) or pixels
925 (negative number). If one or more row-value pairs are specified,
926 then it sets each row to be that height in lines (positive number) or
927 pixels (negative number). If value is default, then the row uses the
928 default height, specified by -rowheight.
929 $table->scan(option, args)
931 This command is used to implement scanning on tables. It has two
932 forms, depending on option:
933 $table->scanMark(x, y)
935 Records x and y and the current view in the table window;
936 used in conjunction with later scan dragto commands. Typically this
937 command is associated with a mouse button press in the widget. It
938 returns an empty string.
939 $table->scanDragto(x, y.)
941 This command computes the difference between its x and y arguments
942 and the x and y arguments to the last scan mark command for the
943 widget. It then adjusts the view by 5 times the difference in
944 coordinates. This command is typically associated with mouse motion
945 events in the widget, to produce the effect of dragging the list at
946 high speed through the window. The return value is an empty string.
947 $table->see(index)
949 Adjust the view in the table so that the cell given by index is
950 positioned as the cell one off from top left (excluding title rows
951 and columns) if the cell is not currently visible on the screen. The
952 actual cell may be different to keep the screen full.
953 $table->selection(option, arg)
955 This command is used to adjust the selection within a table.
956 It has several forms, depending on option:
957 $table->selectionAnchor(index)
959 Sets the selection anchor to the cell given by index. The selection
960 anchor is the end of the selection that is fixed while dragging out
961 a selection with the mouse. The index anchor may be used to refer
962 to the anchor cell.
963 $table->selectionClear(first?last?)
965 If any of the cells between first and last (inclusive) are selected,
966 they are deselected.
967 The selection state is not changed for cells outside this range.
968 first may be specified as all to remove the selection from all
969 cells.
970 $table->selectionIncludes(index)
972 Returns 1 if the cell indicated by index is currently selected, 0 if
973 it isn't.
974 $table->selectionSet(first, ?last?)
976 Selects all of the cells in the range between first and last,
977 inclusive, without affecting the selection state of cells outside
978 that range.
979 perltk note this needs to be perlized
981 $table->set(?row|col?, index, ?value?, ?index, value, ...?)
983 Sets the specified index to the associated value. Table validation
984 will not be triggered via this method. If row or col precedes the
985 list of index/value pairs, then the value is assumed to be a Tcl list
986 whose values will be split and set into the subsequent columns (if
987 row is specified) or rows (for col). For example, set row 2,3 {2,3
988 2,4 2,5} will set 3 cells, from 2,3 to 2,5. The setting of cells is
989 silently bounded by the known table dimensions.
990 $table->spans(?index?, ?rows,cols, index, rows,cols, ...?)
992 This command is used to manipulate row/col spans. When called with
993 no arguments, all known spans are returned as a list of tuples of the
994 form {index span}. When called with only the index, the span for
995 that index only is returned, if any. Otherwise an even number of
996 index rows,cols pairs are used to set spans. A span starts at the
997 index and continues for the specified number of rows and cols.
998 Negative spans are not supported. A span of 0,0 unsets any span on
999 that cell. See EXAMPLES for more info.
1000 $table->tag(option, ?arg, arg, ...?)
1002 This command is used to manipulate tags. The exact behavior of the
1003 command depends on the option argument that follows the tag argument.
1004 cget, cell, and row|col complain about unknown tag names. The
1005 following forms of the command are currently supported:
1006 $table->tagCell(tagName, ?index, ...?)
1008 With no arguments, prints out the list of cells that use the tag.
1009 Otherwise it sets the specified cells to use the named tag,
1010 replacing any tag that may have been set using this method before.
1011 If tagName is '', the cells are reset to the default tag. Tags
1012 added during -*tagcommand evaluation do not register here. If
1013 tagName does not exist, it will be created with the default options.
1014 $table->tagCget(tagName, option)
1016 This command returns the current value of the option named option
1017 associated with the tag given by tagName. Option may have any of
1018 the values accepted by the tag configure widget command.
1019 $table->tagCol(tagName, ?col, ...?)
1021 With no arguments, prints out the list of cols that use the tag.
1022 Otherwise it sets the specified columns to use the named tag,
1023 replacing any tag that may have been set using this method before.
1024 If <tagName> is '', the cols are reset to the default tag. Tags
1025 added during -coltagcommand evaluation do not register here. If
1026 tagName does not exist, it will be created with the default options.
1027 $table->tagConfigure(tagName, ?option?, ?value?, ?option, value, ...?)
1029 This command is similar to the configure widget command except that
1030 it modifies options associated with the tag given by tagName instead
1031 of modifying options for the overall table widget. If no option is
1032 specified, the command returns a list describing all of the
1033 available options for tagName (see Tk_ConfigureInfo for information
1034 on the format of this list). If option is specified with no value,
1035 then the command returns a list describing the one named option
1036 (this list will be identical to the corresponding sublist of the
1037 value returned if no option is specified). If one or more option-
1038 value pairs are specified, then the command modifies the given
1039 option(s) to have the given value(s) in tagName; in this case the
1040 command returns an empty string. See TAGS above for details on the
1041 options available for tags.
1042 $table->tagDelete(tagName)
1044 Deletes a tag. No error if the tag does not exist.
1045 $table->tagExists(tagName)
1047 Returns 1 if the named tag exists, 0 otherwise.
1048 $table->tagIncludes(tagName, index)
1050 Returns 1 if the specified index has the named tag, 0 otherwise.
1051 $table->tagLower(tagName, ?belowThis?)
1053 Lower the priority of the named tag. If belowThis is not specified,
1054 then the tag's priority is lowered to the bottom, otherwise it is
1055 lowered to one below belowThis.
1056 $table->tagNames(?pattern?)
1058 If no pattern is specified, shows the names of all defined tags.
1059 Otherwise the pattern is used as a glob pattern to show only tags
1060 matching that pattern. Tag names are returned in priority order
1061 (highest priority tag first).
1062 $table->tagRaise(tagName, ?aboveThis?)
1064 Raise the priority of the named tag. If aboveThis is not specified,
1065 then the tag's priority is raised to the top, otherwise it is raised
1066 to one above aboveThis.
1067 $table->tagRow(tagName, ?row, ...?)
1069 With no arguments, prints out the list of rows that use the tag.
1070 Otherwise it sets the specified columns to use the named tag,
1071 replacing any tag that may have been set using this method before.
1072 If tagName is '', the rows are reset to use the default tag. Tags
1073 added during -rowtagcommand evaluation do not register here. If
1074 tagName does not exist, it will be created with the default options.
1075 $table->validate(index)
1077 Explicitly validates the specified index based on the current
1078 -validatecommand and returns 0 or 1 based on whether the cell was
1079 validated.
1080 $table->window(option, ?arg, arg, ...?)
1082 This command is used to manipulate embedded windows. The exact
1083 behavior of the command depends on the option argument that follows
1084 the window argument. The following forms of the command are
1085 currently supported:
1086 $table->windowCget(index, option)
1088 This command returns the current value of the option named option
1089 associated with the window given by index. Option may have any of
1090 the values accepted by the window configure widget command.
1091 $table->windowConfigure(index, ?option?, ?value?, ?option, value,
1093 ...?)
1094 This command is similar to the configure widget command except that
1095 it modifies options associated with the embedded window given by
1096 index instead of modifying options for the overall table widget. If
1097 no option is specified, the command returns a list describing all of
1098 the available options for index (see Tk_ConfigureInfo for
1099 information on the format of this list). If option is specified
1100 with no value, then the command returns a list describing the one
1101 named option (this list will be identical to the corresponding
1102 sublist of the value returned if no option is specified). If one or
1103 more option-value pairs are specified, then the command modifies the
1104 given option(s) to have the given value(s) in index; in this case
1105 the command returns an empty string. See EMBEDDED WINDOWS above for
1106 details on the options available for windows.
1107 $table->windowDelete(index, ?index, ...?)
1109 Deletes an embedded window from the table. The associated window
1110 will also be deleted.
1111 $table->windowMove(indexFrom, indexTo)
1113 Moves an embedded window from one cell to another. If a window
1114 already exists in the target cell, it will be deleted.
1115 $table->windowNames(?pattern?)
1117 If no pattern is specified, shows the cells of all embedded windows.
1118 Otherwise the pattern is used as a glob pattern to show only cells
1119 matching that pattern.
1120 $table->xview(args)
1122 This command is used to query and change the horizontal position of
1123 the information in the widget's window. It can take any of the
1124 following forms:
1125 $table->xview()
1127 Returns a list containing two elements. Each element is a real
1128 fraction between 0 and 1; together they describe the horizontal span
1129 that is visible in the window. For example, if the first element is
1130 .2 and the second element is .6, 20% of the table's text is off-
1131 screen to the left, the middle 40% is visible in the window, and 40%
1132 of the text is off-screen to the right. These are the same values
1133 passed to scrollbars via the -xscrollcommand option.
1134 $table->xview(index)
1136 Adjusts the view in the window so that the column given by index is
1137 displayed at the left edge of the window.
1138 $table->xviewMoveto(fraction)
1140 Adjusts the view in the window so that fraction of the total width of
1141 the table text is off-screen to the left. fraction must be a fraction
1142 between 0 and 1.
1143 $table->xviewScroll(number, what)
1145 This command shifts the view in the window left or right according to
1146 number and what. Number must be an integer. What must be either units
1147 or pages or an abbreviation of one of these. If what is units, the
1148 view adjusts left or right by number cells on the display; if it is
1149 pages then the view adjusts by number screenfuls. If number is
1150 negative then cells farther to the left become visible; if it is
1151 positive then cells farther to the right become visible.
1152 $table->yview(?args?)
1154 This command is used to query and change the vertical position of the
1155 text in the widget's window. It can take any of the following forms:
1156 $table->yview()
1158 Returns a list containing two elements, both of which are real
1159 fractions between 0 and 1. The first element gives the position of
1160 the table element at the top of the window, relative to the table as
1161 a whole (0.5 means it is halfway through the table, for example).
1162 The second element gives the position of the table element just
1163 after the last one in the window, relative to the table as a whole.
1164 These are the same values passed to scrollbars via the
1165 -yscrollcommand option.
1166 $table->yview(index)
1168 Adjusts the view in the window so that the row given by index is
1169 displayed at the top of the window.
1170 $table->yviewMoveto(fraction)
1172 Adjusts the view in the window so that the element given by fraction
1173 appears at the top of the window. Fraction is a fraction between 0
1174 and 1; 0 indicates the first element in the table, 0.33 indicates
1175 the element one-third the way through the table, and so on.
1176 $table->yviewscroll(number, what)
1178 This command adjusts the view in the window up or down according to
1179 number and what. Number must be an integer. What must be either
1180 units or pages. If what is units, the view adjusts up or down by
1181 number cells; if it is pages then the view adjusts by number
1182 screenfuls. If number is negative then earlier elements become
1183 visible; if it is positive then later elements become visible.
1184
1186 The initialization creates class bindings that give the following
1187 default behaviour:
1188 [1]
1190 Clicking Button-1 in a cell activates that cell. Clicking into an
1191 already active cell moves the insertion cursor to the character
1192 nearest the mouse.
1193 [2]
1195 Moving the mouse while Button-1 is pressed will stroke out a selection
1196 area. Exiting while Button-1 is pressed causing scanning to occur on
1197 the table along with selection.
1198 [3]
1200 Moving the mouse while Button-2 is pressed causes scanning to occur
1201 without any selection.
1202 [4]
1204 Home moves the table to have the origin in view.
1205 [5]
1207 End moves the table to have the end cell in view.
1208 [6]
1210 Control-Home moves the table to the origin and activates that cell.
1211 [7]
1213 Control-End moves the table to the end and activates that cell.
1214 [8]
1216 Shift-Control-Home extends the selection to the origin.
1217 [9]
1219 Shift-Control-End extends the selection to the end.
1220 [10]
1222 The left, right, up and down arrows move the active cell.
1223 [11]
1225 Shift-<arrow> extends the selection in that direction.
1226 [12]
1228 Control-leftarrow and Control-rightarrow move the insertion cursor
1229 within the cell.
1230 [13]
1232 Control-slash selects all the cells.
1233 [14]
1235 Control-backslash clears selection from all the cells.
1236 [15]
1238 Backspace deletes the character before the insertion cursor in the
1239 active cell.
1240 [16]
1242 Delete deletes the character after the insertion cursor in the active
1243 cell.
1244 [17]
1246 Escape rereads the value of the active cell from the specified data
1247 source, discarding any edits that have may been performed on the cell.
1248 [18]
1250 Control-a moves the insertion cursor to the beginning of the active
1251 cell.
1252 [19]
1254 Control-e moves the insertion cursor to the end of the active cell.
1255 [20]
1257 Control-minus and Control-equals decrease and increase the width of
1258 the column with the active cell in it.
1259 [21]
1261 Moving the mouse while Button-3 (the right button on Windows) is
1262 pressed while you are over a border will cause interactive resizing of
1263 that row and/or column to occur, based on the value of -resizeborders.
1264 Some bindings may have slightly different behavior dependent on the
1265 -selectionmode of the widget. If the widget is disabled using the
1266 -state option, then its view can still be adjusted and cells can still
1267 be selected, but no insertion cursor will be displayed and no cell
1268 modifications will take place. The behavior of tables can be changed
1269 by defining new bindings for individual widgets or by redefining the
1270 class bindings. The default bindings are either compiled in the
1271 TableMatrix.pm file
1272
1274 The number of rows and columns or a table widget should not
1275 significantly affect the speed of redraw. Recalculation and redraw of
1276 table parameters and cells is restricted as much as possible. The
1277 display cell with the insert cursor is redrawn each time the cursor
1278 blinks, which causes a steady stream of graphics traffic. Set the
1279 -insertofftime option to 0 avoid this. The use of a -command with the
1280 table without a cache can cause significant slow-down, as the command
1281 is called once for each request of a cell value.
1282
1284 Set the topleft title area to be one spanning cell. This overestimates
1285 both row and column span by one, but the command does all the
1286 constraining for us. $table span [$table cget -roworigin],[$table cget
1287 -colorigin] [$table cget -titlerows],[$table cget -titlecols] Force a
1288 table window refresh (useful for the slight chance that a bug in the
1289 table is not causing proper refresh): $table configure -padx [$table
1290 cget -padx]
