</pre><H3>DESCRIPTION</H3>

<P>

The <B>tixTList</B></I> command creates a new window (given by the

<I>pathName</I></B> 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.

<P>

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.

<P>

Each list entry is identified by an <B>index</B></I>, which can be in the

following forms:

<UL>

<DL>

<DT> <I>number</I></B>

</I></B>

<DD> 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.

</DL>

<DL>

<DT> <B>end</B></I>

</I></B>

<DD> Indicates the end of the listbox. For some commands this means just

after the last entry; for other commands it means the last entry.

</DL>

<DL>

<DT> <B>@</B></I><I>x</I></B>,<I>y</I></B>

</I></B>

<DD> 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.

</DL>

</UL>

</pre><H3>DISPLAY ITEMS</H3>

<P>

Each list entry in an TList widget is associated with a <B>display

item</B></I>.  The display item determines what visual information should

be displayed for this list entry. Please see the <B>DItem(n)</B></I> manual

page for a list of all display items.

<P>

When a list entry is created by the <B>insert</B></I> command, the type of

its display item is determined by the <B>-itemtype</B></I> option passed

to these commands. If the <B>-itemtype</B></I> is omitted, then by default

used.

</pre><H3>WIDGET COMMAND</H3>

<P>

The <B>tixTList</B></I> command creates a new Tcl command whose name is the

may be used to invoke various operations on the widget.  It has the

following general form:

<pre>

<I>pathName option </I></B>?<I>arg arg ...</I></B>?

<P>

</pre>

<I>PathName</I></B> is the name of the command, which is the same as

determine the exact behavior of the command.  The following

commands are possible for TList widgets:

<DL>

<DT> <I>pathName <B>anchor set <I>index</I></B>

</I></B>

<DD> Sets the anchor to the list entry identified by <I>index</I></B>. The

anchor is the end of the selection that is fixed while dragging out a

selection with the mouse.

</DL>

<DL>

<DT> <I>pathName <B>anchor clear</B></I>

</I></B>

<DD> 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.

</DL>

<DL>

<DT> <I>pathName <B>cget</B></I> <I>option</I></B>

</I></B>

<DD> Returns the current value of the configuration option given by

<I>option</I></B>. <I>Option</I></B> may have any of the values accepted by the

<B>tixTList</B></I> command.

</DL>

<DL>

<DT> <I>pathName <B>configure</B></I> ?<I>option</I></B>? <I>?value option value ...</I></B>?

</I></B>

<DD> Query or modify the configuration options of the widget.  If no

<I>option</I></B> is specified, returns a list describing all of the

available options for <I>pathName</I></B> (see <B>Tk_ConfigureInfo</B></I> for

information on the format of this list). If <I>option</I></B> is specified

with no <I>value</I></B>, 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 <I>option</I></B> is specified).  If

one or more <I>option-value</I></B> 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.  <I>Option</I></B> may have

any of the values accepted by the <B>tixTList</B></I> command.

</DL>

<DL>

<DT> <I>pathName <B>delete</B></I> <I>from</I></B> ?<I>to</I></B>?

</I></B>

<DD> Deletes one or more list entries between the two entries specified by

the indices <I>from</I></B> and <I>to</I></B>. If <I>to</I></B> is not specified, deletes

the single entry specified by <I>from</I></B>.

</DL>

<DL>

<DT> <I>pathName <B>dragsite set <I>index</I></B>

</I></B>

<DD> Sets the dragsite to the list entry identified by

<I>index</I></B>. 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.

</DL>

<DL>

<DT> <I>pathName <B>dragsite clear</B></I>

</I></B>

<DD> 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.

</DL>

<DL>

<DT> <I>pathName <B>dropsite set <I>index</I></B>

</I></B>

<DD> Sets the dropsite to the list entry identified by <I>index</I></B>. 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.

</DL>

<DL>

<DT> <I>pathName <B>dropsite clear</B></I>

</I></B>

<DD> 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.

</DL>

<DL>

<DT> <I>pathName <B>entrycget</B></I> <I>index option</I></B>

</I></B>

<DD> Returns the current value of the configuration option given by

<I>option</I></B> for the entry indentfied by <I>index</I></B>. <I>Option</I></B> may

have any of the values accepted by the <B>insert</B></I> widget command.

</DL>

<DL>

<DT> <I>pathName <B>entryconfigure<I> index </I></B>?<I>option</I></B>? <I>?value option value ...</I></B>?

</I></B>

<DD> Query or modify the configuration options of the list entry indentfied

by <I>index</I></B>. If no <I>option</I></B> is specified, returns a list

describing all of the available options for <I>index</I></B> (see

<B>Tk_ConfigureInfo</B></I> for information on the format of this list). If

<I>option</I></B> is specified with no <I>value</I></B>, 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

<I>option</I></B> is specified). If one or more <I>option-value</I></B> 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.

<I>Option</I></B> may have any of the values accepted by the <B>insert</B></I>

widget command. The exact set of options depends on the

value of the <B>-itemtype</B></I> option passed to the the <B>insert</B></I>

widget command when this list entry is created.

</DL>

<DL>

<DT> <I>pathName <B>insert<I> index </I></B>?<I>option value ...</I></B>?

</I></B>

<DD> Creates a new list entry at the position indicated by <I>index</I></B>. The

following configuration options can be given to configure the list

entry:

<DT> <B>-itemtype<I> type</I></B>

</I></B>

<DD> Specifies the type of display item to be display for the new list

entry. <I>type</I></B> must be a valid display item type. Currently the

available display item types are <B>image</B></I>, <B>imagetext</B></I>,

<B>text</B></I>, and <B>window</B></I>. If this option is not specified, then by

option is used.

</DL>

<DL>

<DT> <B>-state</B></I>

</I></B>

<DD> Specifies whether this entry can be selected or invoked by the user.

Must be either <B>normal</B></I> or <B>disabled</B></I>.

</DL>

</UL>

The <B>insert</B></I> 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 <B>-itemtype</B></I> option. Please see the

<B>DItem(n)</B></I> manual page for a list of the configuration options for

each of the display item types.

<DL>

<DT> <I>pathName <B>info <I>option</I></B> <I>arg ...</I></B>

</I></B>

<DD> Query information about the TList widget. <I>option</I></B> can be one

of the following:

</DL>

<DL>

<DT> <I>pathName <B>info <B>selection</B></I>

</I></B>

<DD> Returns a list of selected elements in the TList widget. If no entries

are selectd, returns an empty string.

</DL>

</UL>

<DL>

<DT> <I>pathName <B>nearest <I>x y</I></B>

</I></B>

<DD> Given an (x,y) coordinate within the TList window, this command

returns the index of the TList element nearest to that coordinate.

</DL>

<DL>

<DT> <I>pathName <B>see <I>index</I></B>

</I></B>

<DD> Adjust the view in the TList so that the entry given by <I>index</I></B> 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.

</DL>

<DL>

<DT> <I>pathName <B>selection <I>option</I></B> <I>arg ...</I></B>

</I></B>

<DD> This command is used to adjust the selection within a TList widget. It

has several forms, depending on <I>option</I></B>:

</DL>

<UL>

<DL>

<DT> <I>pathName <B>selection clear </B></I>?<I>from</I></B>? ?<I>to</I></B>?

</I></B>

<DD> When no extra arguments are given, deselects all of the list entrie(s)

in this TList widget. When only <I>from</I></B> is given, only the list

entry identified by <I>from</I></B> is deselected. When both <I>from</I></B> and

<I>to</I></B> are given, deselects all of the list entrie(s) between

between <I>from</I></B> and <I>to</I></B>, inclusive, without affecting the

selection state of entries outside that range.

</DL>

<DL>

<DT> <I>pathName <B>selection includes <I>index</I></B>

</I></B>

<DD> Returns 1 if the list entry indicated by <I>index</I></B> is currently

</DL>

<UL>

<DL>

<DT> <I>pathName <B>xview</B></I>

</I></B>

<DD> 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

</DL>

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 <B>-xscrollcommand</B></I> option.

<DL>

<DT> <I>pathName <B>xview</B></I> <I>index</I></B>

</I></B>

<DD> Adjusts the view in the window so that the list entry identified by

<I>index</I></B> is aligned to the left edge of the window.

</DL>

<DL>

<DT> <I>pathName <B>xview moveto<I> fraction</I></B>

</I></B>

<DD> Adjusts the view in the window so that <I>fraction</I></B> of the total

width of the TList is off-screen to the left. <I>fraction</I></B> must be

a fraction between 0 and 1.

</DL>

<DL>

<DT> <I>pathName <B>xview scroll <I>number what</I></B>

</I></B>

<DD> This command shifts the view in the window left or right according to

<I>number</I></B> and <I>what</I></B>. <I>Number</I></B> must be an integer.

<I>What</I></B> must be either <B>units</B></I> or <B>pages</B></I> or an

abbreviation of one of these. If <I>what</I></B> is <B>units</B></I>, the view

adjusts left or right by <I>number</I></B> character units (the width of

the <B>0</B></I> character) on the display; if it is <B>pages</B></I> then the

view adjusts by <I>number</I></B> screenfuls. If <I>number</I></B> is negative

then characters farther to the left become visible; if it is positive

then characters farther to the right become visible.

</DL>

<UL>

<DL>

<DT> <I>pathName <B>yview</B></I>

</I></B>

<DD> 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 <B>-yscrollcommand</B></I>

option.

</DL>

<DL>

<DT> <I>pathName <B>yview</B></I> <I>index</I></B>

</I></B>

</I></B>

<DD> Adjusts the view in the window so that the list entry given by

<I>fraction</I></B> appears at the top of the window. <I>Fraction</I></B> 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.

</DL>

<DL>

<DT> <I>pathName <B>yview scroll <I>number what</I></B>

</I></B>

<DD> This command adjust the view in the window up or down according to

<I>number</I></B> and <I>what</I></B>.  <I>Number</I></B> must be an integer.

<I>What</I></B> must be either <B>units</B></I> or <B>pages</B></I>.  If <I>what</I></B>

is <B>units</B></I>, the view adjusts up or down by <I>number</I></B> lines; if

it is <B>pages</B></I> then the view adjusts by <I>number</I></B> screenfuls.

If <I>number</I></B> is negative then earlier entries become visible; if

it is positive then later entries become visible.

If the <B>-selectmode</B></I> 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

<B>-browsecmd</B></I> procedure will be called with an undefined

parameter. It is the responsibility of the <B>-browsecmd</B></I> procedure

to find out the exact highlighted selection in the TList. The

<B>-command</B></I> procedure will be called when the user double-clicks

on a list entry.
