-borderwidth -highlightthickness -setgrid -cursor -relief -xscrollcommand -exportselection -selectbackground -yscrollcommand -highlightbackground -selectborderwidth -highlightcolor -selectforeground
-highlightbackground
,
-highlightcolor
, and
-highlightthickness
options are only supported
by the Tablelist package, but not by Tablelist_tile. When
using the package Tablelist_tile, the options
-selectbackground
,
-selectborderwidth
, and
-selectforeground
have theme-specific default
values.-background -disabledforeground -font -foreground
Command-Line Name: | -activestyle |
Database Name: | activeStyle |
Database Class: | ActiveStyle |
Specifies how to diplay the active item or element (depending on the value of the
-selecttype
configuration option) when the tablelist has the keyboard focus. The allowed values areframe
,none
, andunderline
. The default valueframe
shows a thin frame around the active item or element, which in most cases looks nice. It looks less pretty when applied to the active item if the background color of some of its cells was changed by using thecolumnconfigure
orcellconfigure
widget command and no column separators are shown. The valuenone
specifies that no special indication of the active item or element is to be performed. The valueunderline
produces the same visual effect as in the case of the Tk core listbox.
Command-Line Name: | -arrowcolor |
Database Name: | arrowColor |
Database Class: | ArrowColor |
Specifies the color to use for the up- or down-arrow placed into a column label by the
sortbycolumn
orsortbycolumnlist
subcommand of the Tcl command associated with the widget. This option is only relevant if the value of the-showarrow
option is true. The default value depends on the windowing system in the Tablelist package and on the current theme in Tablelist_tile. For example, if the windowing system isx11
then the default is an empty string, indicating that the arrow will inherit the background color of the label in which it is placed (but is distinguishable from the latter, due to its 3-D border and sunken relief, because in this case the-arrowstyle
option has the default valuesunken10x9
). On the windowing systemwin32
, the default arrow color is#aca899
for Windows XP and Vista, and an empty string for older Windows versions, paired with the default arrow styleflat9x5
andsunken8x7
, respectively. Finally, for the windowing systemsclassic
andaqua
on the Macintosh, the default arrow color is#777777
and the default arrow style isflat7x7
.
Command-Line Name: | -arrowstyle |
Database Name: | arrowStyle |
Database Class: | ArrowStyle |
Specifies the relief, width, and height of the up- or down-arrow placed into a column label by the
sortbycolumn
orsortbycolumnlist
subcommand of the Tcl command associated with the widget. This option is only relevant if the value of the-showarrow
option is true. The currently supported values areflat7x4
,flat7x5
,flat7x7
,flat8x5
,flat9x5
,sunken8x7
,sunken10x9
, andsunken12x11
. The default value depends on the windowing system in the Tablelist package and on the current theme in Tablelist_tile; see the description of the-arrowcolor
option for details.
Command-Line Name: | -arrowdisabledcolor |
Database Name: | arrowDisabledColor |
Database Class: | ArrowDisabledColor |
Specifies the color to use for the up- or down-arrow placed into a column label by the
sortbycolumn
orsortbycolumnlist
subcommand of the Tcl command associated with the widget when the tablelist'sstate
isdisabled
. This option is only relevant if the value of the-showarrow
option is true. When the default value of the-arrowcolor
option is an empty string then this is the default for the-arrowdisabledcolor
option, too; otherwise the latter's default value equals the default foreground color of the header labels indisabled
state.
Command-Line Name: | -columns |
Database Name: | columns |
Database Class: | Columns |
Specifies the widths, titles, and alignments of the columns. The option's value must be a list of the form
width title ?alignment? width title ?alignment? ...Each
width
must be a number. A positive value specifies the column's width in average-size characters of the widget's font. Ifwidth
is negative, its absolute value is interpreted as a column width in pixels. Finally, a value of zero specifies that the column's width is to be made just large enough to hold all the elements in the column, including its header (but no larger than the maximum width indicated by the-maxwidth
column configuration option). In all three cases, the effective column width will be somewhat greater because of the margins created automatically to the left and right of the column.Each
title
specifies the text to be displayed in the column's header, and may optionally be followed in the next list element by analignment
, which specifies how to align the elements of the column. Eachalignment
must be one ofleft
,right
, orcenter
. The default isleft
. Thealignment
also refers to the column's title as long as the-labelalign
option hasn't been specified for that column, or if its value is an empty string.The default value of this option is an empty list, specifying that initially the widget has no columns.
REMARK: Whenever possible, you should specify the value zero for the column widths, i.e., use dynamic-width columns. Besides being more user-friendly, dynamic-width columns have the main advantage that they increase the performance of the item insertion and sorting quite significantly.
Command-Line Name: | -columntitles |
Database Name: | columnTitles |
Database Class: | ColumnTitles |
This option provides a simplified form of specifying dynamic-width, left-aligned tablelist columns. Its value is viewed as a list of column titles. The default is an empty list.
In the simplest case that no columns have been specified yet, setting this option to the value given by the list
title title ...is equivalent to setting the
-columns
option to the value given by the list0 title left 0 title left ...If the columns have already been specified then this option updates their titles (as many of them as possible) and, if the number of elements of its value is greater than the number of columns then it uses the remaining elements as titles of additional dynamic-width, left-aligned columns. For example, if the widget has 3 columns and the option's value is a list of length 5 then the option will update the titles of the 3 columns and will append 2 new dynamic-width, left-aligned columns having as titles the last 2 elements of the list. If the widget has 3 columns and the option specifies just 2 texts then it will update the titles of the first 2 columns only.
Command-Line Name: | -editendcommand |
Database Name: | editEndCommand |
Database Class: | EditEndCommand |
Specifies a Tcl command to be invoked on normal termination of the interactive editing of a cell's contents if the final text of the temporary embedded widget used for the editing is different from its initial one. The command is automatically concatenated with the name of the tablelist widget, the cell's row and column indices, as well as the final contents of the edit window, the resulting script is evaluated in the global scope, and the return value becomes the cell's new contents after destroying the temporary embedded widget. The main purpose of this script is to perform a final validation of the edit window's contents. See the description of the
-forceeditendcommand
option for more about the invocation of the command mentioned above, as well as the INTERACTIVE CELL EDITING section for details on the editing process.
Command-Line Name: | -editstartcommand |
Database Name: | editStartCommand |
Database Class: | EditStartCommand |
Specifies a Tcl command to be invoked when the interactive editing of a cell's contents is started. The command is automatically concatenated with the name of the tablelist widget, the cell's row and column indices, as well as the text displayed in the cell, the resulting script is evaluated in the global scope, and the return value becomes the initial contents of the temporary embedded widget used for the editing. The main purpose of this script is to define validations for the edit window's contents. See the INTERACTIVE CELL EDITING section for details on the editing process.
Command-Line Name: | -forceeditendcommand |
Database Name: | forceEditEndCommand |
Database Class: | ForceEditEndCommand |
Specifies a boolean value that controls the invocation of the command given by the the
-editendcommand
option. If this value is true then the command will be invoked on normal termination of the editing process even if the final text of the temporary embedded widget used for the editing equals its initial one, and will also be invoked when the interactive cell editing is canceled (in the latter case, the text passed to it as last argument will be the cell's original contents, not its final one). The default value of this option is0
, meaning that the command will only be invoked on normal termination of the editing process, if the final text of the temporary embedded widget is different from its initial one. See the INTERACTIVE CELL EDITING section for details on the editing process.Setting this option to true enables you to execute an arbitrary action whenever the interactive cell editing is finished. Just binding a script to the
<Destroy>
event for the temporary embedded widget used for the editing won't work, because that widget might be destroyed and recreated automatically under various circumstances. Alternately, you can use the<<TablelistCellUpdated>>
and<<TablelistCellRestored>>
virtual events, generated by thefinishediting
andcancelediting
subcommands, respectively.
Command-Line Name: | -height |
Database Name: | height |
Database Class: | Height |
Specifies the desired height for the window, in lines. If zero or less then the desired height for the window is made just large enough to hold the header and all the items in the tablelist widget, provided that no column-, row-, or cell-specific fonts are used and no embedded images or windows are displayed in the widget's cells.
Command-Line Name: | -incrarrowtype |
Database Name: | incrArrowType |
Database Class: | IncrArrowType |
Specifies the type of the arrow placed into a column label when sorting the items based on that column in increasing order, with the aid of the
sortbycolumn
orsortbycolumnlist
subcommand of the Tcl command associated with the widget. The value of this option must be one ofup
ordown
. The default isup
. This option is only relevant if the value of the-showarrow
option is true.
Command-Line Name: | -labelactivebackground |
Database Name: | labelActiveBackground |
Database Class: | Foreground |
Specifies the
-activebackground
option for the header labels, i.e., the background color to use when the mouse cursor is positioned over a header label and the value oftk_strictMotif
is false. This option is only defined in the Tablelist package if the Tk version being used supports the-activebackground
option for label widgets. This is checked by Tablelist at initialization time, and will normally be the case for Tk versions 8.3.2 or higher. On the other hand, the Tablelist_tile package doesn't support the-labelactivebackground
option.
Command-Line Name: | -labelactiveforeground |
Database Name: | labelActiveForeground |
Database Class: | Background |
Specifies the
-activeforeground
option for the header labels, i.e., the foreground color to use when the mouse cursor is positioned over a header label and the value oftk_strictMotif
is false. This option is only defined in the Tablelist package if the Tk version being used supports the-activeforeground
option for label widgets. This is checked by Tablelist at initialization time, and will normally be the case for Tk versions 8.3.2 or higher. On the other hand, the Tablelist_tile package doesn't support the-labelactiveforeground
option.
Command-Line Name: | -labelbackground or
-labelbg |
Database Name: | labelBackground |
Database Class: | Background |
Specifies the
-background
option for the header labels. In the package Tablelist_tile this option has a theme-specific default value.
Command-Line Name: | -labelborderwidth or
-labelbd |
Database Name: | labelBorderWidth |
Database Class: | BorderWidth |
Specifies the
-borderwidth
option for the header labels. This option is different from the standard-borderwidth
option defined for the tablelist widget itself. In the package Tablelist_tile this option has a theme-specific default value.
Command-Line Name: | -labelcommand |
Database Name: | labelCommand |
Database Class: | LabelCommand |
Specifies the Tcl command to be invoked when mouse button 1 is pressed over one of the header labels and later released over the same label. When the
<ButtonRelease-1>
event occurs, the command is automatically concatenated with the name of the tablelist widget and the column index of the respective label, and the resulting script is evaluated in the global scope. If the tablelist'sstate
isdisabled
then this action will not take place. The most common value of this option istablelist::sortByColumn
; this command sorts the items based on the column whose index was passed to it as second argument.
Command-Line Name: | -labelcommand2 |
Database Name: | labelCommand2 |
Database Class: | LabelCommand2 |
Specifies the Tcl command to be invoked when mouse button 1 is pressed together with the
Shift
key over one of the header labels and later released over the same label. When the<ButtonRelease-1>
event occurs, the command is automatically concatenated with the name of the tablelist widget and the column index of the respective label, and the resulting script is evaluated in the global scope. If the tablelist'sstate
isdisabled
then this action will not take place. The most common value of this option istablelist::addToSortColumns
; this command adds the column index passed to it as second argument to the list of sort columns and sorts the items based on the columns indicated by the modified list.
Command-Line Name: | -labeldisabledforeground |
Database Name: | labelDisabledForeground |
Database Class: | DisabledForeground |
Specifies the
-disabledforeground
option for the header labels, i.e., the foreground color to use for the labels when the tablelist'sstate
isdisabled
. This option is only defined in the Tablelist package if the Tk version being used supports the-disabledforeground
option for label widgets. This is checked by Tablelist at initialization time, and will normally be the case for Tk versions 8.3.1 or higher. On the other hand, the Tablelist_tile package doesn't support the-labeldisabledforeground
option.
Command-Line Name: | -labelfont |
Database Name: | labelFont |
Database Class: | Font |
Specifies the
-font
option for the header labels. In the package Tablelist_tile this option has a theme-specific default value.
Command-Line Name: | -labelforeground or
-labelfg |
Database Name: | labelForeground |
Database Class: | Foreground |
Specifies the
-foreground
option for the header labels. In the package Tablelist_tile this option has a theme-specific default value.
Command-Line Name: | -labelheight |
Database Name: | labelHeight |
Database Class: | Height |
Specifies the
-height
option for the header labels. This option is only supported by the Tablelist package, but not by Tablelist_tile.
Command-Line Name: | -labelpady |
Database Name: | labelPadY |
Database Class: | Pad |
In the Tablelist package this option specifies the
-pady
configuration option for the header labels. In the Tablelist_tile package the value of the-labelpady
option is mapped to the corresponding components of the value of the-padding
configuration option of the header labels, and the-labelpady
option has a theme-specific default value.
Command-Line Name: | -labelrelief |
Database Name: | labelRelief |
Database Class: | Relief |
Specifies the
-relief
option for the header labels. This option is different from the standard-relief
option defined for the tablelist widget itself. The default value israised
.
Command-Line Name: | -listvariable |
Database Name: | listVariable |
Database Class: | Variable |
Specifies the name of a variable. The value of the variable is a list to be displayed inside the widget; if the variable value changes then the widget will automatically update itself to reflect the new value. The value of the variable must be a valid list. Each list element corresponds to a row within the widget, and must be a valid list itself; its elements correspond to the cells within the respective row. Attempts to assign a variable whose value does not fulfil these conditions to
-listvariable
will cause an error. Attempts to unset a variable in use as a-listvariable
will fail but will not generate an error.REMARK: For increased efficiency, updating the widget to reflect a changed value of the variable specified with this option is, whenever possible, done at idle time (i.e., when there are no events to process). On the other hand, most tablelist subcommands make it necessary to perform an immediate update of the widget's internal list according to the value of this variable, before executing the subcommand in question. Doing this repeatedly can become quite inefficient. To avoid performance problems, you should always try to separate the operations that build up the value of the variable specified by this option from other commands. For example, instead of
tablelist::tablelist .tbl ... -listvariable var set var {} for {set row 0} {$row < 1000} {incr row} { lappend var ... .tbl cellconfigure $row,3 -image ... }you should write
tablelist::tablelist .tbl ... -listvariable var set var {} for {set row 0} {$row < 1000} {incr row} { lappend var ... } for {set row 0} {$row < 1000} {incr row} { .tbl cellconfigure $row,3 -image ... }The first method above is quite inefficient, because it requires 1000 updates of the widget's internal list. The second method performs incomparably faster, because it needs only one synchronization (at the beginning of the second loop).
Command-Line Name: | -movablecolumns |
Database Name: | movableColumns |
Database Class: | MovableColumns |
Specifies a boolean value that determines whether the columns can be moved interactively. See the DEFAULT AND INDIVIDUAL BINDINGS FOR THE HEADER LABELS section below for information on moving a column interactively. The default value is

hand2
.
Command-Line Name: | -protecttitlecolumns |
Database Name: | protectTitleColumns |
Database Class: | ProtectTitleColumns |
Specifies a boolean value that determines whether the boundary of the title column area shall be protected from being crossed when moving a column interactively. See the DEFAULT AND INDIVIDUAL BINDINGS FOR THE HEADER LABELS section below for information on moving a column interactively. The default value is
0
, specifying that non-title columns can be moved into the title column area and vice-versa.
Command-Line Name: | -resizablecolumns |
Database Name: | resizableColumns |
Database Class: | ResizableColumns |
Specifies a boolean value that determines whether the columns can be resized interactively. See the DEFAULT AND INDIVIDUAL BINDINGS FOR THE HEADER LABELS section below for information on interactive column resizing. The default value is
1
.
Command-Line Name: | -resizecursor |
Database Name: | resizeCursor |
Database Class: | ResizeCursor |
Specifies the mouse cursor to be used during interactive column resizing. The default value is
sb_h_double_arrow
.
Command-Line Name: | -selectmode |
Database Name: | selectMode |
Database Class: | SelectMode |
Specifies one of several styles for manipulating the selection. The value of the option may be arbitrary, but the default bindings expect it to be either
single
,browse
,multiple
, orextended
. The default value isbrowse
.
Command-Line Name: | -selecttype |
Database Name: | selectType |
Database Class: | SelectType |
Specifies one of two selection types for the tablelist widget:
row
orcell
. If the selection type isrow
then the default bindings will select and deselect entire items, and the whole row having the location cursor will be displayed as active when the tablelist has the keyboard focus. If the selection type iscell
then the default bindings will select and deselect individual elements, and the single cell having the location cursor will be displayed as active when the tablelist has the keyboard focus. The default value isrow
.
Command-Line Name: | -setfocus |
Database Name: | setFocus |
Database Class: | SetFocus |
Specifies a boolean value that determines whether a click with the left mouse button anywhere into the tablelist's body, including the separators and the embedded images (more precisely, any descendants of the tablelist widget having the binding tag
TablelistBody
) should set the focus to the body of the tablelist widget if the latter'sstate
isnormal
. The default value is1
.
Command-Line Name: | -showarrow |
Database Name: | showArrow |
Database Class: | ShowArrow |
Specifies a boolean value that determines whether the
sortbycolumn
andsortbycolumnlist
subcommands of the Tcl command associated with the widget should place an arrow indicating the sort order into the header label(s) of the column(s) specified by their first argument. The default value is1
.
Command-Line Name: | -showlabels |
Database Name: | showLabels |
Database Class: | ShowLabels |
Specifies a boolean value that determines whether the header labels are to be shown or not. The default value is
1
.

Specifies a boolean value that determines whether the columns are to be separated with borders. The default value is
0
. The separators are implemented as thin frames with sunken relief in the package Tablelist, and as tile separator widgets in the package Tablelist_tile. They are attached to the right edges of the header labels, and are only created if the value of this option is true. There is no support for horizontal separators in tablelist widgets, but a nice distinguishing effect for the rows can be achieved with the aid of the-stripebackground
option discussed below.
Command-Line Name: | -snipstring |
Database Name: | snipString |
Database Class: | SnipString |
Specifies the string to be used as snip indicator when displaying the elements that don't fit into their cells. The default is an ellipsis (
"..."
).
Command-Line Name: | -sortcommand |
Database Name: | sortCommand |
Database Class: | SortCommand |
Specifies a command to be used for the comparison of the items when invoking the
sort
subcommand of the Tcl command associated with the tablelist widget. To compare two items (viewed as lists of cell contents within one row each) during thesort
operation, the command is automatically concatenated with the two items and the resulting script is evaluated. The script should return an integer less than, equal to, or greater than zero if the first item is to be considered less than, equal to, or greater than the second, respectively.
Command-Line Name: | -spacing |
Database Name: | spacing |
Database Class: | Spacing |
Specifies additional space to provide above and below each row of the widget. The option's value may have any of the standard forms for screen distances. It defaults to
0
.
Command-Line Name: | -state |
Database Name: | state |
Database Class: | State |
Specifies one of two states for the tablelist widget:
normal
ordisabled
. If the widget is disabled then neither items nor columns may be inserted, deleted, updated, or moved, the items, header labels, and the up- or down-arrow are drawn in the-disabledforeground
,-labeldisabledforeground
, and-arrowdisabledcolor
color, respectively, the selection cannot be modified and is not shown (although the selection information is retained), the header labels are completely insensitive, and no interactive cell editing can be performed. In addition, in disabled state any color options specified at column, row, or cell level will be ignored.
Command-Line Name: | -stretch |
Database Name: | stretch |
Database Class: | Stretch |
Specifies the columns to be stretched in order to fill the tablelist window if necessary. The option's value may be
all
or a list of column indices in any of the forms described in the COLUMN INDICES section below. In the second case, the specified column indices are replaced with their numerical equivalents, except for the indexend
, which is viewed as a dynamic column index whose numerical equivalent might change during program execution and therefore will be recomputed every time the columns are stretched. The list will be updated automatically whenever columns are inserted, deleted, or moved. The number of pixels by which a column is stretched is proportional to its width in pixels. The default value of this option is an empty list, meaning that no column will be stretched to eliminate the blank space that might appear at the right of the table. (Note that the blank space following the header labels is filled with a dummy, insensitive label having the same background, borderwidth, and relief as the "normal" header labels.) This option is ignored if the value of the-width
configuration option is zero or less.
Command-Line Name: | -stripebackground or
-stripebg |
Database Name: | stripeBackground |
Database Class: | Background |
Specifies the background color to use when displaying the items belonging to a stripe. Each stripe is composed of the same number
stripeHeight
of consecutive non-hidden items, according to the value of the-stripeheight
configuration option. The firststripeHeight
non-hidden items are "normal" ones; they are followed by a stripe composed of the nextstripeHeight
non-hidden items, which in turn is followed by the same number of "normal" non-hidden items, and so on. In the Tablelist package and in most themes supported by Tablelist_tile, the default value is an empty string, indicating that the stripes will inherit the background color specified by the-background
configuration option. When using Tablelist_tile with thetileqt
theme then the default value is given by the global KDE optionalternateBackground
, which in turn depends on the current color scheme. In this case it is recommended to either keep that default value retrieved from KDE, or to use an explicitly specified empty string if no stripes are to be displayed. The-stripebackground
option has a higher priority than the-background
column configuration option, but a lower priority than the-background
option specified at row or cell level.
Command-Line Name: | -stripeforeground or
-stripefg |
Database Name: | stripeForeground |
Database Class: | Foreground |
Specifies the foreground color to use when displaying the items belonging to a stripe. Each stripe is composed of the same number
stripeHeight
of consecutive non-hidden items, according to the value of the-stripeheight
configuration option. The firststripeHeight
non-hidden items are "normal" ones; they are followed by a stripe composed of the nextstripeHeight
non-hidden items, which in turn is followed by the same number of "normal" non-hidden items, and so on. The default value is an empty string, indicating that the stripes will inherit the foreground color specified by the-foreground
configuration option. The-stripeforeground
option has a higher priority than the-foreground
column configuration option, but a lower priority than the-foreground
option specified at row or cell level.
Command-Line Name: | -stripeheight |
Database Name: | stripeHeight |
Database Class: | StripeHeight |
Specifies the number of items in each stripe. If zero or less then no stripes are displayed. The default is
1
.
Command-Line Name: | -takefocus |
Database Name: | takeFocus |
Database Class: | TakeFocus |
This option determines whether the widget accepts the focus during keyboard traversal. It is almost identical to the standard option of the same name (see the options manual entry for details). The only difference is that not the widget itself but its body child (containing the items) will receive the focus during keyboard traversal with the standard keys (
Tab
andShift-Tab
).
Command-Line Name: | -targetcolor |
Database Name: | targetColor |
Database Class: | TargetColor |
Specifies the color of the temporary gap displayed in the tablelist's body or header to indicate the target position when moving a row or column interactively. The default value is
black
.
Command-Line Name: | -titlecolumns |
Database Name: | titleColumns |
Database Class: | TitleColumns |
Specifies the number of the non-scrollable columns at the left edge of the window, also called title columns. The positions of these columns will not change when adjusting the horizontal view by invoking the
scan
,seecell
,seecolumn
, orxview
subcommand. The default value is0
. The value of this option also determines the scrolling unit used by the commands mentioned above when shifting the horizontal view: if it is positive then the horizontal scrolling is performed column-wise, otherwise by character units (the width of the0
character).The end of the title column area is visualized with the aid of a separator, attached to the right edge of the header label corresponding to the last non-hidden title column. This special separator is always displayed to mark the end of the title columns (if any), independently of the value of the
-showseparators
option. The user can easily distinguish it from the other separators by means of its background color, which is different from that of the other separator frames.For technical reasons (the use of the
-elide
option for a text widget tag), this option is not supported for Tk versions earlier than 8.3.
Command-Line Name: | -tooltipaddcommand |
Database Name: | tooltipAddCommand |
Database Class: | TooltipAddCommand |
Specifies a Tcl command to be used for displaying cell- and column label-specific balloon help. When the mouse pointer enters a cell, the command is automatically concatenated with the name of the tablelist widget and the cell's row and column indices, and the resulting script is evaluated in the global scope. Similarly, when the mouse pointer enters a header label, the command is automatically concatenated with the name of the tablelist widget, the number
-1
, and the column index of the respective label, and the resulting script is evaluated in the global scope. In both cases, the action described above is only triggered if both the value of this option and that of-tooltipdelcommand
are nonempty strings.For example, consider the procedure
tooltipAddCmd
shown below, which makes use of theDynamicHelp::add
command from the BWidget package to display the full cell and label texts as tooltips for the cells and header labels with snipped contents.proc tooltipAddCmd {tbl row col} { if {($row >= 0 && [$tbl iselemsnipped $row,$col fullText]) || ($row < 0 && [$tbl istitlesnipped $col fullText])} { DynamicHelp::add $tbl -text $fullText } }A tablelist widget can use this procedure by specifying
... -tooltipaddcommand tooltipAddCmd -tooltipdelcommand DynamicHelp::deleteIf you prefer to use the
tooltip::tooltip
command from the tooltip package contained in tklib then the procedure becomesproc tooltipAddCmd {tbl row col} { if {($row >= 0 && [$tbl iselemsnipped $row,$col fullText]) || ($row < 0 && [$tbl istitlesnipped $col fullText])} { tooltip::tooltip $tbl $fullText } }and can be used by specifying
... -tooltipaddcommand tooltipAddCmd -tooltipdelcommand "tooltip::tooltip clear"Please note that in the less common case that the name of your tablelist widget contains spaces, the
tooltip::tooltip clear
command won't work as expected. As a workaround you can use the slightly modified approach shown below:proc tooltipDelCmd tbl { tooltip::tooltip $tbl "" } ... -tooltipaddcommand tooltipAddCmd -tooltipdelcommand tooltipDelCmdBoth examples above make use of the
iselemsnipped
andistitlesnipped
subcommands, to make sure that the full cell and label texts will only be displayed for those cells and header labels whose contents are snipped.
Command-Line Name: | -tooltipdelcommand |
Database Name: | tooltipDelCommand |
Database Class: | TooltipDelCommand |
Specifies a Tcl command to be used for removing the cell- or column label-specific balloon help. When the mouse pointer leaves a cell or a header label, the command specified by this option is automatically concatenated with the name of the tablelist widget and the resulting script is evaluated in the global scope. This action is only triggered if both the value of this option and that of
-tooltipaddcommand
are nonempty strings. Common values for this option are"DynamicHelp::delete"
(which requires the BWidget package) and"tooltip::tooltip clear"
(which requires the tooltip package contained in tklib). Their usage is shown in the examples above.
Command-Line Name: | -width |
Database Name: | width |
Database Class: | Width |
Specifies the desired width for the window, in average-size characters of the widget's font. If zero or less then the desired width for the window is made just large enough to hold all the columns in the tablelist widget.
tablelist::tablelist
command creates a
new window named pathName
and of the class
Tablelist
, and makes it into a tablelist
widget. Additional options, described above, may be specified
on the command line or in the option database to configure aspects
of the tablelist such as its colors, font, and columns. The
tablelist::tablelist
command returns its
pathName
argument. At the time this
command is invoked, there must not exist a window named
pathName
, but pathName
's
parent must exist.-exportselection
option),
then it will observe the standard X11 protocols for handling the
selection. Tablelist widget selections are available as types
STRING
and UTF8_STRING
; the
value of the selection will be a text built by taking all of the
rows having at least one non-hidden selected element, joining these
elements together with tabs, and the resulting strings in turn with
newlines. If a tablelist widget that is exporting its
selection is the selection owner and some other window claims
ownership of the selection away from it, then the virtual event
<<TablelistSelectionLost>>
is
generated.-xscrollcommand

-yscrollcommand
options. They also
support scanning, as described below.-background

-selectbackground
, and
-selectforeground
options can also be specified
at column, row, and cell level, by using the columnconfigure
, rowconfigure
, and cellconfigure
subcommands of
the Tcl command associated with the tablelist widget. For
this reason, a particular cell can have up to four values for one
and the same color or font option. If these values conflict,
then the option specified at the highest priority level is
used. The decreasing priority order is cell, row, column,
widget.
If one of these options hasn't been specified at cell, row, or column level, or if its value for that level is an empty string (this is explicitly allowed), then that option will not be used at that particular level.

or ttk::checkbutton
(the latter three only in
the presence of the tile widget engine), or the value returned by
one of the registration commands for widgets from the packages BWidget, Iwidgets, combobox (by Bryan Oakley), and Mentry (or Mentry_tile). For
example, you can use -editwindow
ComboBox
after registering the ComboBox
widget for interactive cell editing with the aid of the tablelist::addBWidgetComboBox
command. Similarly, you can use -editwindow
combobox
after registering Bryan Oakley's
combobox widget for interactive cell editing by invoking the
tablelist::addOakleyCombobox
command. The value of this option can be overridden for
individual cells by using the cell
configuration option of the same name.-font font

color
or -fg color
-formatcommand
command
command
is a nonempty string, then it is
automatically concatenated with the cell's text, the resulting
script is evaluated in the global scope, and the return value is
displayed in the cell or added to the selection instead of the
original data. For example, if a time value in seconds is
being inserted into the cell and command
is the
procedure formatDate
defined as
proc formatDate clockVal { return [clock format $clockVal -format "%Y-%m-%d"] }
then the text displayed in the cell will be the date in the
specified format, not the time value in seconds. Notice that
this option is only used for preparing the text to be displayed or
returned when exporting the selection, and does not affect the
internal cell contents. For example, the get
, getcolumns
, getcells
, rowcget
, columncget
, cellcget
, sort
, sortbycolumn
, and sortbycolumnlist
subcommands all
operate on the original cell text, which is contained in the
widget's internal list. In the case of the above example,
this will make it possible to sort the items very easily by time,
with a second's precision, even if their visual representation only
contains the year, month, and day.
The -formatcommand
option comes in handy if
only images or embedded windows are to be displayed in a column but
the texts associated with the cells may not simply be empty strings
because they are needed for other purposes (like sorting or
editing). In such cases, a procedure returning an empty
string can be used as the option's value, thus making sure that the
textual information contained in that column remains hidden.
In the more sophisticated case that the result of the formatting
should also depend on the cell's row, you will have to invoke the
formatinfo
subcommand, which provides the necessary information about the cell
whose content is being formatted.

must be the result of
an invocation of the image create
command, or an empty string, specifying that no image is to be

image will be displayed to the right of the text, otherwise to its
left. The text and the image are separated from each other by
a gap corresponding to the width of a space character in the given
label's font.-maxwidth
width
width
must be a number. A positive
value specifies the column's maximum width in average-size
characters of the widget's font. If width
is negative, its absolute value is interpreted as a maximum column
width in pixels. Finally, a value of zero (which is the
default) specifies that the column's maximum width is to be made
just large enough to hold all the elements in the column, including
its header. This option is only relevant if the given column
has dynamic width, i.e., if its width was set to
0

abbreviations of) the string all

. This option
is only relevant if the value of the -showarrow
widget configuration option
is true.-showlinenumbers
boolean
0
.
The following details assume that the given column's
-showlinenumbers
option was set to true:
Associating the line numbers with the non-hidden rows takes place
automatically whenever items are inserted, deleted, updated, moved,
or sorted. For increased efficiency, this is in most cases
done at idle time. For example, if several items are inserted
into or deleted from the tablelist widget, then the necessary
renumbering of the non-hidden rows will be performed as an idle
callback, the next time the event loop is entered and there are no
events to process. The line numbers will override any
previous contents of the column's cells. They are, per
default, displayed without leading zeros, but this (and the display
format in general) can be changed with the aid of the -formatcommand
column
configuration option.
The sortbycolumn
and sortbycolumnlist
subcommands as
well as the tablelist::sortByColumn
and tablelist::addToSortColumns
commands check the column indices passed to them as arguments and
don't perform any sorting by those columns that have been
configured to display the line numbers (see the corresponding
descriptions for details).

column index as first argument or the sortbycolumnlist
command having
the given column index as element of its first argument. To
compare two elements during the sortbycolumn
or
sortbycolumnlist
operation,
command
is automatically concatenated with the
two elements and the resulting script is evaluated. The
script should return an integer less than, equal to, or greater
than zero if the first element is to be considered less than, equal
to, or greater than the second, respectively.-sortmode

Use dictionary-style comparison. This is the same as
ascii , except: (a) case is ignored except as a
tie-breaker; (b) if two strings contain embedded numbers, the
numbers compare as integers, not characters. For example,
bigBoy sorts between bigbang and
bigboy , and x10y sorts between
x9y and x11y . |

width is to be made just large enough to hold all the elements in
the column, including its header (but no larger than the maximum
width indicated by the -maxwidth
column configuration
option). This option is tied to the width
element corresponding to the given column in the list specifying
the value of the -columns

changes in either will automatically be reflected in the
other.-wrap
boolean
0
.
If the specified column has static width and the value of this
option is true then elements of the column that are too long to be
displayed in a single line will be broken up into several
lines. The same applies to the individual lines of the
multi-line elements (i.e., elements containing newline characters):
they will also be wrapped if necessary, thus giving rise to
additional line breaks. In both cases, the line breaks are
chosen at word boundaries wherever possible, and they are only used
for the external representation of the strings contained in the
given column, without affecting the internal contents of the
cells.-background

CAUTION: Tk versions 8.3 - 8.4.12 had a bug that caused a segmentation fault if the whole content of a text widget was elided. This bug was also present in Tk 8.5.a1 - 8.5.a3. When using one of these earlier Tk versions, this bug will produce a crash if all the rows of a tablelist widget are hidden. It is your responsibility to avoid such situations when using a Tk version having this bug!

then the image will be displayed to the right of the cell's text,
otherwise to its left. The text and the image are separated
from each other by a gap of 4 pixels. If for the same cell
the -window
option
was specified with a nonempty value then it overrides the
-image
option. If the tablelist's

is
disabled
then this option will be ignored.
To display an image in a cell, Tablelist makes use of an embedded label widget (which is created on demand). This requires more memory than inserting the image directly into the tablelist's body, but has the main advantage of making it possible to adjust the width of the label containing the widget to fit into its column. This has the visual effect of cutting off part of the image from its right side. To make sure that images with transparent background will be displayed correctly, the background color of the label widgets containing the embedded images is automatically updated whenever necessary.

the column was specified with a non-zero width or was resized
interactively, then the width of the embedded window (if any) will
be adjusted automatically so the window fills the whole horizontal
space belonging to that column (except the left and right
margins). Please note that in this case the cell's text will
remain hidden. On the other hand, if the column is of dynamic
width then this option will be ignored and both the cell's text and
its embedded window (if any) will be displayed as usual. The
easiest way to avoid this discrepancy is to set the cell's text to
an empy string or make sure that the column's elements are always
displayed as empty strings, by using the -formatcommand

configuration option.-text text

then
this option will be ignored.
There are several situations where the embedded window will be destroyed and later recreated by invoking the script mentioned above. For example, when changing the value of some of the tablelist widget or column configuration options, sorting the items, or moving a row or a column, the widget's contents will be redisplayed, which makes it necessary to recreate the embedded windows. This operation won't preserve the changes made on the embedded windows after their creation. For this reason, you should avoid any changes on embedded windows outside their creation scripts.

option on both cell and column
level. If the cell-level option was set explicitly then its
value determines the editability of the cell's contents.
Otherwise the value of the column-level option is used to decide
whether the cell can be edited interactively. From this rule
it follows that you can enable interactive cell editing for a whole
column by setting its -editable
option to
true. To exclude some of the column's cells from interactive
editing, set their -editable
option to
false.editcell
subcommand, which is invoked
implicitly by clicking with the left mouse button into an editable
cell or using keyboard navigation to move from one editable cell
into another. If the selection type is
cell
and the location cursor is in an editable
cell, then the interactive editing of the active element can also
be started by pressing Return
or
KP_Enter
. Per default, the
editcell
subcommand creates a temporary entry
widget and embeds it into the cell whose index was passed to it as
argument. You can, however, use the
-editwindow
column or cell
configuration option to specify another widget instead of an entry,
like a Tk core text, spinbox, or checkbutton widget, or a tile
entry, combobox, or checkbutton, or one of the 16 currently
supported widgets from the packages BWidget, Iwidgets, combobox (by Bryan Oakley), and Mentry (or Mentry_tile).
Before specifying a widget from one of these library packages as
the value of the -editwindow
column or cell
configuration option, you must register it for interactive cell
editing by invoking the corresponding
tablelist::add*
command. The Tk core
entry, text, spinbox, and checkbutton widgets, as well as the tile
entry, combobox, and checkbutton widgets are automatically
registered for cell editing.-formatcommand
option of the
cell's column. However, if the value of the -editstartcommand
configuration
option is a nonempty string, then the text displayed in the cell is
passed to that command as its last argument (following the
tablelist's path name as well as the cell's row and column
indices), the resulting script is evaluated in the global scope,
and the return value becomes the edit window's contents. From
within this script you can invoke the cancelediting
subcommand, which
destroys the temporary embedded widget and cancels the editing of
its contents. The main goal of this script is, however, to
enable you to define validations for the editing process.
This can be done either with the aid of the options for entry
validation, supported by Tk versions 8.3 and higher (see the
entry reference page), or by using the widget callback
package Wcb, available for Tk
versions 8.0 and higher. The Iwidgets package (available for
Tk versions 8.0 or higher) provides its own validation facilities,
which can equally be used if the edit window is a widget belonging
to that extension. In either case, you will need the path
name of the temporary embedded widget or that of its entry or
entry-like component; use the editwinpath
and entrypath
subcommands to get these path
names. Another purpose of the command indicated by the
-editstartcommand
option is to enable you to
prepare the edit window in various other ways. For example,
if the latter is a combobox widget then you can set its
-editable
option to false or (for a tile
combobox) set its state to readonly
, and you
will have to populate its listbox component. In the same
script, you can change some of the embedded widget's visual
attributes (like its background, selection background, or selection
foreground color). (Notice that this can also be done with
the aid of the Tk option database.)Control-i
inserts a tab,
Control-j
inserts a newline, and if the edit window is
a text widget then Return
and KP_Enter
insert a newline character, too. Tab
and
Shift-Tab
are used for navigation between the editable
cells, just like Alt-Left
, Alt-Right
,
Alt-Up
, Alt-Down
, Alt-Prior
,
Alt-Next
, Alt-Home
, and
Alt-End
(as well as Control-Home
and
Control-End
, except in the case of a text
widget). On Mac OS Classic and Mac OS X Aqua the
Command
key is used instead of Alt
.
The editing can be aborted with the Escape
key (or by
invoking the cancelediting
subcommand) and
terminated normally with Return
or
KP_Enter
(together with Control
for a
text widget). The bindings for the keys used for normal
termination of the editing just invoke the finishediting
subcommand; the
latter can also be called explicitly to terminate the editing
programmatically. Normal termination is also triggered by
clicking with the left mouse button anywhere in the tablelist's
body, outside the cell just being edited, or moving into another
editable cell by using keyboard navigation.-editendcommand
configuration
option is a nonempty string, then the edit window's final text is
passed to that command as its last argument (following the
tablelist's path name as well as the cell's row and column
indices), the resulting script is evaluated in the global scope,
and the return value becomes the cell's new internal contents after
destroying the temporary embedded widget. The main goal of
this script is to enable you to do a final validation of the edit
window's contents. From within this script you can invoke the
rejectinput
subcommand, which prevents the script's return value from becoming
the cell's new contents; this subcommand also prevents the
destruction of the temporary embedded widget. Another purpose
of the command indicated by the -editendcommand
option is to convert the edit window's text to the cell's new
internal contents, which is necessary if, due to the
-formatcommand
column configuration option, the cell's internal value is different
from its external representation. See the description of the
-forceeditendcommand
option
for more about the invocation of the command mentioned above.number |
Specifies the item as a numerical index, where 0
corresponds to the first item in the tablelist. |
knumber |
Specifies the item by its full key, composed of the letter
k and the sequence number associated with the
item, as returned by the getkeys widget command. |

Indicates the item containing the element that has the location
cursor. Depending on the selection type, this item as a whole
or just its element having the location cursor will be displayed
according to the value of the -activestyle configuration option
when the tablelist has the keyboard focus. This item is
specified with the activate widget command or as the row
containing the element specified with the activatecell widget command. |

Indicates the end of the tablelist. For most commands
this refers to the last item in the tablelist, but for a few
commands such as index ,
insert , and insertlist , as well as for the
target of the move command
it refers to the item just after the last one. |
@x,y |
Indicates the item that covers the point in the tablelist
window specified by x and y

the closest item to that point is used. The coordinates
x and y are expected to be
relative to the tablelist window itself (not its body
component). |
name |
Specifies the row by the value of its -name configuration option.
name must be different from all the above row
indices, and should be unique (if several rows have the same name
then this value is considered to indicate the first matching
row). |
In the widget command descriptions below, arguments named
index
, first

last
, source
, and
target
always contain row indices in one of the
above forms.
number |
Specifies the column as a numerical index, where 0
corresponds to the first column in the tablelist. |
active |
Indicates the column containing the element that has the
location cursor. If the selection type is
cell then this element will be displayed
according to the value of the -activestyle configuration option
when the tablelist has the keyboard focus. This element is
specified with the activatecell widget command. |
anchor |
Indicates the column containing the anchor point for the cell
selection, which is set with the cellselection anchor widget
command. |

Indicates the last column of the tablelist, except for the
commands insertcolumns and insertcolumnlist , as well as for
the target of the movecolumn command, in which cases it
refers to the column just after the last one. |
@x,y |
Indicates the column that covers the point in the tablelist
window specified by x and y
(in pixel coordinates). If no column covers that point, then
the closest column to that point is used. The coordinates
x and y are expected to be
relative to the tablelist window itself (not its body
component). |

lastColumn
, sourceColumn
,
and targetColumn
always contain column indices
in one of the above forms.
row,col |
Indicates the cell having the row index row
and column index col .
row may be a number, a full key (of the form
knumber ), active ,
anchor , end (where the
latter indicates the last row in the tablelist), or a row
name. col may be a number,
active , anchor ,
end , or a column name. |
active |
Indicates the element that has the location cursor. If
the selection type is cell then this element
will be displayed according to the value of the -activestyle configuration option
when the tablelist has the keyboard focus. This element is
specified with the activatecell widget command. |
anchor |
Indicates the anchor point for the cell selection, which is set
with the cellselection
anchor widget command. |
end |
Indicates the last cell in the last row of the tablelist. |
@x,y |
Indicates the cell that covers the point in the tablelist
window specified by x and y
(in pixel coordinates). If no cell covers that point, then
the closest cell to that point is used. The coordinates
x and y are expected to be
relative to the tablelist window itself (not its body
component). |
In the widget command descriptions below, arguments named
cellIndex
, firstCell
, and
lastCell
always contain cell indices in one of
the above forms.

new Tcl command whose name is pathName
.
This command may be used to invoke various operations on the
widget. It has the following general form:

the one named attribute, or an empty string if no corresponding
value exists (you can use the hasattrib
subcommand to distinguish
this case from the one that the value of an existing
attribute is an empty string). If one or more

you to write event handling scripts that are valid not only for the
tablelist's body but also for the separators, multi-line cells, and
embedded images.pathName
cancelediting
editcell
subcommand, destroys the
temporary widget embedded into the cell, and restores the original
cell contents. This command enables you to cancel the
interactive cell editing from within the Tcl command specified by
the -editstartcommand
configuration
option if that pre-edit callback encounters an error when preparing
the text to be inserted into the edit window. The command is
also invoked implicitly by pressing the Escape
key
when a cell is being edited. The return value is an empty
string. Immediately before returning this value, the command
generates the virtual event
<<TablelistCellRestored>>
. If
no cell was being edited when the command was invoked then an empty
string is returned without generating a virtual event.pathName cellattrib

is specified, the command returns a list of pairs, each of which
contains the name and the value of an attribute for the cell.
If name
is specified with no

, then the command returns the value of
the one named cell attribute, or an empty string if no
corresponding value exists (you can use the hascellattrib
subcommand to
distinguish this case from the one that the value of an
existing cell attribute is an empty string). If one or
more name

width was specified as 0
(and was not changed by
interactive column resizing) then the return value is the actual
number of pixels corresponding to the widest non-hidden element of
the column, including its header. With the

column width obtained by increasing the value described above by
the number of additional pixels that might have been added to the
requested column width by a stretch operation (see the -stretch
widget and -stretchable
column
configuration options). Finally, if the optional argument is

finishediting
editcell
subcommand by
destroying the temporary widget embedded into the cell and updating
the cell's contents. The exact steps involved are as
follows: First, the widget's final text is compared to its
original one. If they are equal then the edit window is
destroyed and the cell's original contents are restored. If
the two strings are different and the value of the -editendcommand
configuration
option is a nonempty string, then the widget's final text is passed
to that command as its last argument (following the tablelist's
path name as well as the cell's row and column indices), the
resulting script is evaluated in the global scope, and the return
value becomes the cell's new contents after destroying the edit
window. However, if from within this script the rejectinput
subcommand was
invoked then the cell's value is not changed and the embedded
widget remains displayed in the cell; in this case the command
returns the boolean value 0
. In all the other
cases, the return value is 1
. Immediately before
returning the value 1
, the command generates the
virtual event
<<TablelistCellUpdated>>
. If
no cell was being edited when the command was invoked then the same
value 1
is returned but no virtual event is generated.
This subcommand is called implicitly by pressing
Return
or KP_Enter
(together with
Control
if the edit window is a text widget) when
editing a cell, or by clicking with the left mouse button anywhere
in the tablelist's body, outside the cell just being edited, or
moving into another editable cell by using keyboard navigation.
There are also situations where an explicit invocation of this subcommand is needed, in order to make sure that the cell just being edited gets updated with the text entered by the user. For example, if a tablelist widget is part of a dialog used for editing some data, then the binding script associated with the button designed to accept the data should call this subcommand, because otherwise, if the button is pressed during interactive cell editing then the text entered into the edit window will get lost.

-formatcommand
column
configuration option. It returns a three-element list
containing information about the tablelist cell whose content is
being formatted with the aid of that command. The first
element of the list is the full key (of the form

) associated with the item
containing the tablelist element that is being formatted. The
second and third elements of the list are the cell's row and column
indices.
This subcommand is needed in cases where the result of the
formatting should depend on the cell's row. To be able to use
it, specify the value of the -formatcommand
column configuration option as [list

, like in the
following example:

of the sequence numbers associated with the tablelist items
corresponding to the indices specified by
indexList
. Each item of a tablelist
widget has a unique sequence number that remains unchanged until
the item is deleted, thus acting as a key that uniquely identifies
the item even if the latter's position (i.e., row index)
changes. This command provides read-only access to these

corresponds to one item, and it is in turn a list whose elements
correspond to the elements of that item, except that it has one
additional element, holding the item's key.
The itemlistvar
command provides an
efficient way for accessing this internal list, instead of
retrieving the items with the get
subcommand or using the -listvariable
option (these methods
consume significantly more memory). It can be useful in
situations where the elements of a tablelist widget are to be
accessed for creating text files, HTML output, XML data, database
commands, etc. This should, however, be a strictly readonly
access; otherwise the results will be unpredictable!

sorting the items, the command conditionally adjusts the vertical

then the cell being edited is brought into view; (b) else, if
exactly one item is selected then the view is shifted to bring that
item into view; (c) else, if the tablelist's body is the most

columnIndex
, in increasing or decreasing order,
as specified by the optional argument. The default is

. The sorting process is
controlled by the values of the -sortmode

options for the
given column. If both the value of the -showarrow
configuration option and
that of the -showarrow
option for the specified
column are true then an up- or down-arrow indicating the sort order
will be placed into the column's label. The shape of the
arrow depends on the command's optional argument and on the value
of the -incrarrowtype
configuration
option. If the label's text is right-aligned then the arrow
will be displayed on the left side of the label, otherwise on its
right side. After sorting the items, the vertical view is
adjusted in the same way as in the case of the sort
subcommand.
The actions described above are only performed if the specified

argument, which must be a

The items are first sorted based on the column specified by the
last significant element of columnIndexList
,
then based on the one given by the last but one significant
element, and so on. The order of each sort operation is taken
from the optional argument sortOrderList
, whose
elements must be (abbreviations of) increasing
or decreasing
. If this argument was not
specified or contains less elements than
columnIndexList
then the missing sort orders
are assumed to be increasing
. Each
sorting process is controlled by the values of the -sortmode
and -sortcommand
options for the
respective column. If the column's index was specified among
the first 9 significant elements of
columnIndexList
and both the value of the
-showarrow
configuration option and that of the -showarrow
option for that column
are true then an up- or down-arrow indicating the sort order will
be placed into the column's label. The shape of the arrow
depends on the respective sort order and on the value of the
-incrarrowtype
configuration option. If the label's text is right-aligned
then the arrow will be displayed on the left side of the label,
otherwise on its right side. If more than one sort arrows are
to be displayed then the first 9 sort ranks (1
for the

Returns an empty string. After toggling the hidden state of
the specified columns, the

is not supported for Tk versions earlier than 8.3.
CAUTION: Tk versions 8.3 - 8.4.12 had a bug that caused a segmentation fault if the whole content of a text widget was elided. This bug was also present in Tk 8.5.a1 - 8.5.a3. When using one of these earlier Tk versions, this bug will produce a crash if all the rows of a tablelist widget are hidden. It is your responsibility to avoid such situations when using a Tk version having this bug!

is replaced with
a new binding tag called TablelistBody
.
The latter has all the events of the Listbox
widget class, and several of its binding scripts are obtained from
those of Listbox
by replacing the event fields
%W
, %x
, and
%y
with the path name of the tablelist widget
and the x and y coordinates relative to the latter. These
values are assigned to the help variables
tablelist::W
, tablelist::x
,
and tablelist::y
by invoking the helper command
tablelist::convEventFields
as follows:
foreach {tablelist::W tablelist::x tablelist::y} \ [tablelist::convEventFields %W %x %y] {}
This conversion of the event fields is necessary because the Tcl
command associated with a tablelist expects any coordinates
relative to the widget itself, not its body component. It
makes use of help variables from the tablelist
namespace in order to avoid any conflicts with global
variables.
Several of the events have no %x
and
%y
fields; in this case another helper command
tablelist::getTablelistPath
is used to set the help variable tablelist::W
to the path name of the tablelist widget:
set tablelist::W [tablelist::getTablelistPath %W]
The binding tag TablelistBody
replaces the
class name (Frame
or
TSeparator
) of the separator widgets,
too. It also replaces the binding tag
Message
of the message widgets used to display
multi-line elements, as well as the binding tag
Label
of the label widgets used to display
embedded images. This makes sure that the default handling of
the mouse events on the column separators, multi-line cells, and
embedded images is the same as in the rest of the tablelist's
body.
When defining individual bindings for tablelist widgets, the
same conversion of the event fields is needed as for the default
bindings. For example, the binding script below for the
tablelist widget .tbl
prints the index of the cell
where mouse button 1 was clicked:
bind [.tbl bodytag] <Button-1> { foreach {tablelist::W tablelist::x tablelist::y} \ [tablelist::convEventFields %W %x %y] {} puts "clicked on cell [.tbl containingcell $tablelist::x $tablelist::y]" }
By associating the script with the binding tag returned by the
bodytag
subcommand
instead of just with the path name of the tablelist's body we make
sure to have the same event handling for the separators, multi-line
cells, and embedded images as for the rest of the tablelist's
body.
The bindings associated with the binding tag
TablelistBody
, created automatically by the
tablelist::tablelist
command, ensure that the
body component of a tablelist has the same default behavior as a
listbox widget. If the selection type is
row
(which is the default) then everything
described in the "DEFAULT BINDINGS" section of the listbox
manual entry applies to the body component of a tablelist,
too. The only difference is that the word "element" in that
manual page has to be replaced with "item" when applying the
description to the body of a tablelist widget.
If the selection type is cell
then
everything described in the "DEFAULT BINDINGS" section of the
listbox manual entry applies to the body component of a
tablelist, too, with the following extensions and changes:
Tab
or Shift-Tab
is pressed, the
location cursor (active element) moves to the next/previous
element. If the selection mode is browse
or extended
then the new active element is also
selected and all other elements are deselected. In
extended
mode the new active element becomes
the selection anchor. Notice that these bindings replace the
common inter-widget navigation via Tab
and
Shift-Tab
with inter-cell navigation. Just like
in the case of the text widget, Control-Tab
and
Control-Shift-Tab
are intended to be used for
widget-to-widget keyboard navigation. Unfortunately, this
won't always work because some window managers intercept the latter
key sequences and use them for their own purposes (like
inter-workplace navigation). For this reason, Tablelist
supports the additional key sequences Meta-Tab
and
Meta-Shift-Tab
as replacements for
Control-Tab
and Control-Shift-Tab
,
respectively.Left
or Right
key is pressed,
the location cursor (active element) moves to the previous/next
element of the active row. If the selection mode is
browse
or extended
then the
new active element is also selected and all other elements are
deselected. In extended
mode the new
active element becomes the selection anchor.extended
mode, Shift-Left
and Shift-Right
move the location cursor (active
element) to the previous/next element of the active row and also
extend the selection to that element in a fashion similar to
dragging with mouse button 1.Home
or End
key is pressed,
the location cursor (active element) moves to the first/last
element of the active row, the new active element is selected, and
all other elements are deselected.extended
mode, Shift-Home
and Shift-End
extend the selection to the first/last
element of the active row. In multiple
mode, Shift-Home
and Shift-End
move the
location cursor to the first/last element of the active row.Return
and KP_Enter
start the interactive
editing of the active element.Just like in the case of the listbox widget, any changes to the
selection will automatically generate the virtual event
<<ListboxSelect>>
. Instead of
this event (which is supported for compatibility reasons), the
virtual event <<TablelistSelect>>
can be used to be made aware of any changes to tablelist
selection. Both events will be generated independently of the
selection type.
The following binding associated with the binding tag
TablelistBody
is only valid if the selection
mode is single
or
multiple
: If mouse button 1 is clicked on
an item and then dragged outside that item, and the value of the
-movablerows
configuration option is true, then the mouse cursor takes on the
shape specified by the -movecursor
option, indicating that
the item in question is being moved to another position, visualized
with the aid of a gap placed before the target item. This
operation ends when mouse button 1 is released, and can be canceled
by pressing the Escape
key. In both cases, the
mouse cursor is reset to its original value, specified by the
-cursor
configuration option. After
releasing mouse button 1, the source item is moved before the one
indicated by the gap mentioned above and the virtual event
<<TablelistRowMoved>>
is
generated.
tablelist::tablelist
command
automatically creates the following bindings for the header
labels:-resizablecolumns
configuration
option and that of the -resizable
option for the column
corresponding to that label are true, then the mouse cursor takes
on the shape specified by the -resizecursor
option. By
clicking mouse button 1 in this area and moving the mouse while its
button 1 is down, the column corresponding to that label will be
resized by the amount of the cursor motion. The interactive
column resizing ends when mouse button 1 is released, and can be
canceled by pressing the Escape
key. In both
cases, the mouse cursor is reset to its original value, specified
by the -cursor
configuration option. When
the column resize operation is finished, the virtual event
<<TablelistColumnResized>>
is
generated.-movablecolumns
configuration
option is true, then the mouse cursor takes on the shape specified
by the -movecolumncursor
option,
indicating that the column in question is being moved to another
position, visualized with the aid of a gap placed before the label
of the target column. This operation ends when mouse button 1
is released, and can be canceled by pressing the
Escape
key when the mouse pointer is outside the
label. In both cases, the mouse cursor is reset to its
original value, specified by the -cursor
configuration option. After releasing mouse button 1, the
source column is moved before the one indicated by the gap
mentioned above and the virtual event
<<TablelistColumnMoved>>
is
generated.-labelcommand
option is a nonempty
string, then this command is concatenated with the name of the
tablelist widget and the column index of the respective label, and
the resulting script is evaluated in the global scope. If
another nonempty label command was specified at column level by
using the columnconfigure
option of the Tcl
command associated with the tablelist widget, then that
column-specific command will be used instead of the global
one. If mouse button 1 was pressed together with the
Shift
key then the widget- or column-specific command
mentioned above will be replaced with the one specified by the
-labelcommand2
option at widget or column level.<<Button3>>
as
<Button-3>
for all windowing systems and
additionally as <Control-Button-1>
for
Mac OS Classic and Mac OS X Aqua. If this event occurs over a
header label and both the value of the -resizablecolumns
configuration
option and that of the -resizable
option for the column
corresponding to that label are true, then the width of that column
is set to zero, i.e., it is made just large enough to hold all the
elements in the column, including the header (but no larger than
the maximum width indicated by the -maxwidth
column configuration
option), and the virtual event
<<TablelistColumnResized>>
is
generated. The same action is triggered by double-clicking
the resize area of a header label.<<ShiftButton3>>
as
<Shift-Button-3>
for all windowing
systems and additionally as
<Shift-Control-Button-1>
for Mac OS
Classic and Mac OS X Aqua. If this event occurs over a header
label and both the value of the -resizablecolumns
configuration
option and that of the -resizable
option for the column
corresponding to that label are true, then the width of that column
is set to its last static width (if any) and the virtual event
<<TablelistColumnResized>>
is
generated. The same action is triggered by double-clicking
the resize area of a header label with the Shift
key
held down.If the tablelist's state
is disabled
then
none of the above actions occur: the labels are completely
insensitive.
If you want to define non-default bindings for the header
labels, it is recommended to associate them with the binding tag
whose name is returned by the labeltag
subcommand and make use of the
helper commands tablelist::getTablelistColumn
and tablelist::getTablelistPath
.
For example, to replace the default binding for
<Button-3>
with a script that performs a
column-dependent action, you can proceed like in the code shown
below:
bind [.tbl labeltag] <Button-3> { puts "right-clicked on header label no. [tablelist::getTablelistColumn %W]" break }
tablelist::tablelist
command extends
and partially redefines the bindings of some of the components of
the temporary embedded widget used for interactive cell editing,
which is started by clicking mouse button 1 in an editable cell or
using keyboard navigation to move from one editable cell into
another. If the selection type is cell
and the location cursor is in an editable cell, then the
interactive editing of the active element can also be started by
pressing Return
or KP_Enter
.
The affected components of the temporary embedded widget depend
on the edit window: the widget itself in case of a Tk or tile
checkbutton; the edit window's entry children in case of a mentry
widget; the only entry or entry-like component of the edit window
in all other cases (see also the entrypath
subcommand). The list
of binding tags of these edit window components contains two
addditional tags, inserted just before their path names: the
binding tag whose name is returned by the editwintag
subcommand, followed by the
tag TablelistEdit
. The bindings described
below are associated with the tag
TablelistEdit
, and can be overridden for
individual tablelist widgets by making use of the binding tag given
by the editwintag
subcommand.
Control-i
inserts a tabulator character into the
edit window's entry or entry-like components (if any), at the point
of the insertion cursor.Control-j
inserts a newline character into the
edit window's entry or entry-like components (if any), at the point
of the insertion cursor.Return
and KP_Enter
insert a newline character at the point
of the insertion cursor. Otherwise they terminate the editing
and destroy the edit window.Control-Return
and Control-KP_Enter
terminate the editing and destroy the edit window.Escape
aborts the editing and destroys the edit
window.Tab
and Shift-Tab
terminate the editing in the current cell, move the edit window
into the next/previous editable cell of the tablelist, select the
contents of the edit window's first entry or entry-like component
(if any), and set the insertion cursor to its end. If the new
edit window is a text widget then its contents are left
unselected. Notice that these bindings replace the common
inter-widget navigation via Tab
and
Shift-Tab
with inter-cell navigation. Just like
in the case of the text widget, Control-Tab
and
Control-Shift-Tab
are intended to be used for
widget-to-widget keyboard navigation during interactive cell
editing. Unfortunately, this won't always work because some
window managers intercept the latter key sequences and use them for
their own purposes (like inter-workplace navigation). For
this reason, Tablelist supports the additional key sequences
Meta-Tab
and Meta-Shift-Tab
as
replacements for Control-Tab
and
Control-Shift-Tab
, respectively.Alt-Left
/Alt-Right
(Command-Left
/Command-Right
on Mac OS
Classic and Mac OS X Aqua) terminates the editing in the current
cell, moves the edit window into the previous/next editable cell of
the row, selects the contents of the edit window's first entry or
entry-like component (if any), and sets the insertion cursor to its
end. If the new edit window is a text widget then its
contents are left unselected. The key sequence
Meta-Left
/Meta-Right
has the same effect
as Alt-Left
/Alt-Right
. If
tk_strictMotif
is false and the edit window is
not a text widget then Meta-b
and Meta-f
behave the same as Alt-Left
and
Alt-Right
, respectively. If the edit window is a
Tk or tile checkbutton widget then
Left
/Right
has the same effect as
Alt-Left
/Alt-Right
.Alt-Up
/Alt-Down
(Command-Up
/Command-Down
on Mac OS
Classic and Mac OS X Aqua) terminates the editing in the current
cell, moves the edit window one line up/down within the column,
selects the contents of the edit window's first entry or entry-like
component (if any), and sets the insertion cursor to its end.
If the new edit window is a text widget then its contents are left
unselected. The key sequence
Meta-Up
/Meta-Down
has the same effect as
Alt-Up
/Alt-Down
. If
tk_strictMotif
is false and the edit window is
not a text widget or an Iwidgets combobox, then
Control-p
and Control-n
behave the same
as Alt-Up
and Alt-Down
,
respectively. If the edit window is a Tk or tile entry, Tk or
tile checkbutton, BWidget Entry, Iwidgets
entryfield/spinner/spinint, or a mentry widget of type
"FixedPoint"
, then Up
/Down
has the same effect as
Alt-Up
/Alt-Down
.Alt-Prior
/Alt-Next
(Command-Prior
/Command-Next
on Mac OS
Classic and Mac OS X Aqua) terminates the editing in the current
cell, moves the edit window up/down by one page within the column,
selects the contents of the edit window's first entry or entry-like
component (if any), and sets the insertion cursor to its end.
If the new edit window is a text widget then its contents are left
unselected. The key sequence
Meta-Prior
/Meta-Next
has the same effect
as Alt-Prior
/Alt-Next
. If the edit
window is not a text widget, BWidget SpinBox, Oakley combobox, or a
mentry widget of type "Date"
, "Time"
,
"DateTime"
, or "IPAddr"
, then
Prior
/Next
has the same effect as
Alt-Prior
/Alt-Next
.Alt-Home
/Alt-End
(Command-Home
/Command-End
on Mac OS
Classic and Mac OS X Aqua) terminates the editing in the current
cell, moves the edit window into the first/last editable cell of
the tablelist, selects the contents of the edit window's first
entry or entry-like component (if any), and sets the insertion
cursor to its end. If the new edit window is a text widget
then its contents are left unselected. The key sequence
Meta-Home
/Meta-End
has the same effect as
Alt-Home
/Alt-End
. If
tk_strictMotif
is false and the edit window is
not a text widget then Meta-<
and
Meta->
behave the same as Alt-Home
and
Alt-End
, respectively. If the edit window is not
a text widget then
Control-Home
/Control-End
has the same
effect as Alt-Home
/Alt-End
.Before moving the edit window, the key sequences mentioned under
7 - 11 move the active item or element and change the
(cell)selection and the (cell)selection anchor in the body of the
tablelist widget. For example, if
Alt-Up
/Alt-Down
or
Meta-Up
/Meta-Down
(Command-Up
/Command-Down
on Mac OS
Classic and Mac OS X Aqua) is pressed when editing a cell that is
not the first/last editable cell within its column, then the active
item or element (depending on the selection type) moves one line
up/down. If the selection mode is browse
or extended
then the new active item or element
is also selected and all other items or elements are
deselected. In extended
mode the new
active item or element becomes the (cell)selection anchor.
This is exactly the same behavior as the one exhibited by the
Up
and Down
keys in the tablelist's
body.
If the tablelist's state
is disabled
then
none of the above actions occur.
