WIDGET-SPECIFIC OPTIONS

[-browsecmd browsecmd] Specifies a TCL command to be executed when the user browses
through the entries in the TList widget. [-command command] Specifies the TCL command to
be executed when the user invokes a list entry in the TList widget. Normally the user
invokes a list entry by double-clicking it or pressing the Return key.
[-foreground foreground] Specifies the default foreground color for the list entries.
[-height height] Specifies the desired height for the window in number of characters.
[-itemtype itemType] Specifies the default type of display item for this TList widget.
When you call the insert widget commands, display items of this type will be created if
the -itemtype option is not specified . [-orient orient] Specifies the order of
tabularizing the list entries. When set to "vertical", the entries are arranged in a
column, from top to bottom. If the entries cannot be contained in one column, the
remaining entries will go to the next column, and so on. When set to "horizontal", the
entries are arranged in a row, from left to right. If the entries cannot be contained in
one row, the remaining entries will go to the next row, and so on. [-padx padX] The
default horizontal padding for list entries. [-padx padY] The default vertical padding
for list entries. [-selectbackground selectBackground] Specifies the background color for
the selected list entries. [-selectborderwidth selectBorderWidth] Specifies a non-
negative value indicating the width of the 3-D border to draw around selected items. The
value may have any of the forms acceptable to Tk_GetPixels.
[-selectforeground selectForeground] Specifies the foreground color for the selected list
entries. [-selectmode 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, or extended; the default value is single.
[-sizecmd sizeCmd] Specifies a TCL script to be called whenever the TList widget changes
its size. This command can be useful to implement "user scroll bars when needed" features.
[-state state] Specifies whether the TList command should react to user actions. When set
to "normal", the TList reacts to user actions in the normal way. When set to "disabled",
the TList can only be scrolled, but its entries cannot be selected or activated.
[-width width] Specifies the desired width for the window in characters.

DESCRIPTION

       The tixTList command creates a new window (given by the pathName argument)  and  makes  it
       into a TList widget.  Additional options, described above, may be specified on the command
       line or in the option database to configure aspects of the TList widget such as its cursor
       and relief.

       The  TList  widget  can be used to display data in a tabular format. The list entries of a
       TList widget are similar to the entries in the Tk listbox widget. The main differences are
       (1)  the TList widget can display the list entries in a two dimensional format and (2) you
       can use graphical images as well as multiple colors and fonts for the list entries.

       Each list entry is identified by an index, which can be in the following forms:

              number An integer that indicates the position of the entry in the list. 0 means the
                     first position, 1 means the second position, and so on.

              end    Indicates  the  end  of the listbox. For some commands this means just after
                     the last entry; for other commands it means the last entry.

              @x,y   Indicates the element that covers the point in the listbox window  specified
                     by x and y (in pixel coordinates). If no element covers that point, then the
                     closest element to that point is used.

DISPLAY ITEMS

       Each list entry in an TList widget is associated with a display item.   The  display  item
       determines what visual information should be displayed for this list entry. Please see the
       tixDisplayStyle manual page for a list of all display items.

       When a list entry is created by the insert command,  the  type  of  its  display  item  is
       determined  by the -itemtype option passed to these commands. If the -itemtype is omitted,
       then by default the type specified by this TList widget's -itemtype option is used.

WIDGET COMMAND

The tixTList command creates a new Tcl command whose name is the same as the path name of
the TList widget's window. This command may be used to invoke various operations on the
widget. It has the following general form:
pathName option ?arg arg ...?
PathName is the name of the command, which is the same as the TList widget's path name.
Option and the args determine the exact behavior of the command. The following commands
are possible for TList widgets:

pathName anchor set index
Sets the anchor to the list entry identified by index. The anchor is the end of the
selection that is fixed while dragging out a selection with the mouse.

pathName anchor clear
Removes the anchor, if any, from this TList widget. This only removes the
surrounding highlights of the anchor entry and does not affect its selection
status.

pathName cget option
Returns the current value of the configuration option given by option. Option may
have any of the values accepted by the tixTList command.

pathName configure ?option? ?value option value ...?
Query or modify the configuration options of the widget. If no option is
specified, returns a list describing all of the available options for pathName (see
Tk_ConfigureInfo for information on the format of this list). If option is
specified with no value, then the command returns a list describing the one named
option (this list will be identical to the corresponding sublist of the value
returned if no option is specified). If one or more option-value pairs are
specified, then the command modifies the given widget option(s) to have the given
value(s); in this case the command returns an empty string. Option may have any of
the values accepted by the tixTList command.

pathName delete from ?to?
Deletes one or more list entries between the two entries specified by the indices
from and to. If to is not specified, deletes the single entry specified by from.

pathName dragsite set index
Sets the dragsite to the list entry identified by index. The dragsite is used to
indicate the source of a drag-and-drop action. Currently drag-and-drop
functionality has not been implemented in Tix yet.

pathName dragsite clear
Remove the dragsite, if any, from the this TList widget. This only removes the
surrounding highlights of the dragsite entry and does not affect its selection
status.

pathName dropsite set index
Sets the dropsite to the list entry identified by index. The dropsite is used to
indicate the target of a grag-and-drop action. Currently drag-and-drop
functionality has not been implemented in Tix yet.

pathName dropsite clear
Remove the dropsite, if any, from the this TList widget. This only removes the
surrounding highlights of the dropsite entry and does not affect its selection
status.

pathName entrycget index option
Returns the current value of the configuration option given by option for the entry
indentfied by index. Option may have any of the values accepted by the insert
widget command.

pathName entryconfigure index ?option? ?value option value ...?
Query or modify the configuration options of the list entry indentfied by index. If
no option is specified, returns a list describing all of the available options for
index (see Tk_ConfigureInfo for information on the format of this list). If option
is specified with no value, then the command returns a list describing the one
named option (this list will be identical to the corresponding sublist of the value
returned if no option is specified). If one or more option-value pairs are
specified, then the command modifies the given option(s) to have the given
value(s); in this case the command returns an empty string. Option may have any of
the values accepted by the insert widget command. The exact set of options depends
on the value of the -itemtype option passed to the the insert widget command when
this list entry is created.

pathName insert index ?option value ...?
Creates a new list entry at the position indicated by index. The following
configuration options can be given to configure the list entry:

-itemtype type
Specifies the type of display item to be display for the new list entry.
type must be a valid display item type. Currently the available display item
types are image, imagetext, text, and window. If this option is not
specified, then by default the type specified by this TList widget's
-itemtype option is used.

-state Specifies whether this entry can be selected or invoked by the user. Must
be either normal or disabled.
The insert widget command accepts additional configuration options to configure the
display item associated with this list entry. The set of additional configuration options
depends on the type of the display item given by the -itemtype option. Please see the
tixDisplayStyle manual page for a list of the configuration options for each of the
display item types.

pathName info option arg ...
Query information about the TList widget. option can be one of the following:

pathName info anchor index
; Returns the index of the current anchor, if any, of the TList widget. If
the anchor is not set, returns the empty string.

pathName info dragsite index
Returns the index of the current dragsite, if any, of the TList widget. If
the dragsite is not set, returns the empty string.

pathName info dropsite index
Returns the index of the current dropsite, if any, of the TList widget. If
the dropsite is not set, returns the empty string.

pathName info selection
Returns a list of selected elements in the TList widget. If no entries are
selectd, returns an empty string.

pathName nearest x y
Given an (x,y) coordinate within the TList window, this command returns the index
of the TList element nearest to that coordinate.

pathName see index
Adjust the view in the TList so that the entry given by index is visible. If the
entry is already visible then the command has no effect; if the entry is near one
edge of the window then the TList scrolls to bring the element into view at the
edge; otherwise the TList widget scrolls to center the entry.

pathName selection option arg ...
This command is used to adjust the selection within a TList widget. It has several
forms, depending on option:

pathName selection clear ?from? ?to?
When no extra arguments are given, deselects all of the list entrie(s) in
this TList widget. When only from is given, only the list entry identified
by from is deselected. When both from and to are given, deselects all of the
list entrie(s) between between from and to, inclusive, without affecting the
selection state of entries outside that range.

pathName selection includes index
Returns 1 if the list entry indicated by index is currently selected;
returns 0 otherwise.

pathName selection set from ?to?
Selects all of the list entrie(s) between between from and to, inclusive,
without affecting the selection state of entries outside that range. When
only from is given, only the list entry identified by from is selected.

pathName xview args
This command is used to query and change the horizontal position of the information
in the widget's window. It can take any of the following forms:

pathName xview
Returns a list containing two elements. Each element is a real fraction
between 0 and 1; together they describe the horizontal span that is visible
in the window. For example, if the first element is .2 and the second
element is .6, 20% of the TList entry is off-screen to the left, the middle
40% is visible in the window, and 40% of the entry is off-screen to the
right. These are the same values passed to scrollbars via the
-xscrollcommand option.

pathName xview index
Adjusts the view in the window so that the list entry identified by index is
aligned to the left edge of the window.

pathName xview moveto fraction
Adjusts the view in the window so that fraction of the total width of the
TList is off-screen to the left. fraction must be a fraction between 0 and
1.

pathName xview scroll number what
This command shifts the view in the window left or right according to number
and what. Number must be an integer. What must be either units or pages or
an abbreviation of one of these. If what is units, the view adjusts left or
right by number character units (the width of the 0 character) on the
display; if it is pages then the view adjusts by number screenfuls. If
number is negative then characters farther to the left become visible; if it
is positive then characters farther to the right become visible.

pathName yview ?args?
This command is used to query and change the vertical position of the entries in
the widget's window. It can take any of the following forms:

pathName yview
Returns a list containing two elements, both of which are real fractions
between 0 and 1. The first element gives the position of the list element
at the top of the window, relative to the TList as a whole (0.5 means it is
halfway through the TList, for example). The second element gives the
position of the list entry just after the last one in the window, relative
to the TList as a whole. These are the same values passed to scrollbars via
the -yscrollcommand option.

pathName yview index
Adjusts the view in the window so that the list entry given by index is
displayed at the top of the window.

pathName yview moveto fraction
Adjusts the view in the window so that the list entry given by fraction
appears at the top of the window. Fraction is a fraction between 0 and 1; 0
indicates the first entry in the TList, 0.33 indicates the entry one-third
the way through the TList, and so on.

pathName yview scroll number what
This command adjust the view in the window up or down according to number
and what. Number must be an integer. What must be either units or pages.
If what is units, the view adjusts up or down by number lines; if it is
pages then the view adjusts by number screenfuls. If number is negative
then earlier entries become visible; if it is positive then later entries
become visible.

BINDINGS

[1] If the -selectmode is "browse", when the user drags the mouse pointer over the list
entries, the entry under the pointer will be highlighted and the -browsecmd
procedure will be called with one parameter, the index of the highlighted entry.
Only one entry can be highlighted at a time. The -command procedure will be called
when the user double-clicks on a list entry.

[2] If the -selectmode is "single", the entries will only be highlighted by mouse
<ButtonRelease-1> events. When a new list entry is highlighted, the -browsecmd
procedure will be called with one parameter indicating the highlighted list entry.
The -command procedure will be called when the user double-clicks on a list entry.

[3] If the -selectmode is "multiple", when the user drags the mouse pointer over the
list entries, all the entries under the pointer will be highlighted. However, only
a contiguous region of list entries can be selected. When the highlighted area is
changed, the -browsecmd procedure will be called with an undefined parameter. It is
the responsibility of the -browsecmd procedure to find out the exact highlighted
selection in the TList. The -command procedure will be called when the user double-
clicks on a list entry.

[4] If the -selectmode is "extended", when the user drags the mouse pointer over the
list entries, all the entries under the pointer will be highlighted. The user can
also make disjointed selections using <Control-ButtonPress-1>. When the highlighted
area is changed, the -browsecmd procedure will be called with an undefined
parameter. It is the responsibility of the -browsecmd procedure to find out the
exact highlighted selection in the TList. The -command procedure will be called
when the user double-clicks on a list entry.

EXAMPLE

       This example demonstrates how to use an TList to store a list of numbers:

       set image [tix getimage folder] set  t  [tixTList  .t  -orient  vertical]  $t  insert  end
       -itemtype  imagetext  -image  $image  -text  one  $t insert end -itemtype imagetext -image
       $image -text two $t insert end -itemtype imagetext -image $image -text three $t insert end
       -itemtype  imagetext  -image  $image  -text  four $t insert end -itemtype imagetext -image
       $image -text five $t insert end -itemtype  imagetext  -image  $image  -text  six  pack  $t
       -expand yes -fill both
