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

<P>

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

<I>pathName</I></B> argument) and makes it into a HList widget.

Additional options, described above, may be specified on the command

line or in the option database to configure aspects of the

HList widget such as its cursor and relief.

<P>

The HList widget can be used to display any data that have a

hierarchical structure, for example, file system directory trees. The

list entries are indented and connected by branch lines according to

their places in the hierachy.

<P>

Each list entry is identified by an <B>entryPath</B></I>. The entryPath is a

sequence of <B>entry names</B></I> separated by the separator charactor

(specified by the <B>-separator</B></I> option). An <B>entry name</B></I> can be

any string that does not contain the separator charactor, or it can be

the a string that contains only one separator charactor.

<P>

For example, when "." is used as the separator charactor,

"one.two.three" is the entryPath for a list entry whose parent is

"one.two", whose parent is "one", which is a toplevel entry (has no

parents).

<P>

Another examples: ".two.three" is the entryPath for a list entry whose

parent is ".two", whose parent is ".", which is a toplevel entry.

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

<P>

Each list entry in an HList 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.

When a list entry is created by the <B>add</B></I> or <B>addchild</B></I> widget

commands, 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 the type specified by

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

<P>

The <B>tixHList</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 HList widgets:

<DL>

<DT> <I>pathName <B>add<I> entryPath </I></B>?<I>option value ...</I></B>?

</I></B>

<DD> Creates a new list entry with the pathname <I>entryPath</I></B>. A list

entry must be created after its parent is created (unless this entry

is a top-level entry, which has no parent). This command returns the

entryPath of the newly created list entry. The following

configuration options can be given to configure the list entry:

</DL>

<UL>

<DL>

<DT> <B>-at<I> position</I></B>

</I></B>

<DD> Insert the new list at the position given by <I>position</I></B>.

<I>position</I></B> must be a valid integer. the Position <B>0</B></I> indicates

the first position, <B>1</B></I> indicates the second position, and so on.

</DL>

<DL>

<DT> <B>-after<I> afterWhich</I></B>

</I></B>

<DD> Insert the new list entry after the entry identified by

<I>afterWhich</I></B>. <I>afterWhich</I></B> must be a valid list entry and it

mush have the same parent as the new list entry

</DL>

<DL>

<DT> <B>-before<I> beforeWhich</I></B>

</I></B>

<DD> Insert the new list entry before the entry identified by

<I>beforeWhich</I></B>. <I>beforeWhich</I></B> must be a valid list entry and it

mush have the same parent as the new list entry

</DL>

<DL>

<DT> <B>-data<I> string</I></B>

</I></B>

<DD> Specifies a string to associate with this list entry. This string can

be queried by the <B>info</B></I> widget command. The application

programmer can use the <B>-data</B></I> option to associate the list entry

with the data it represents.

</DL>

<DL>

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

</I></B>

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

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

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

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

</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>add</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>addchild<I> parentPath </I></B>?<I>option value ... </I></B>?

</I></B>

<DD> Adds a new child entry to the children list of the list entry

identified by <I>parentPath</I></B>. Or, if <I>parentPath</I></B> is set to be

the empty string, then creates a new toplevel entry. The name of the

new list entry will be a unique name automatically generated by the

HList widget. Usually if <I>parentPath</I></B> is <B>foo</B></I>, then the

entryPath of the new entry will be <B>foo.1</B></I>, <B>foo.2</B></I>, ... etc.

This command returns the entryPath of the newly created list entry.

<I>option</I></B> can be any option for the <B>add</B></I> widget command.

</DL>

<DL>

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

</I></B>

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

anchor is the end of the selection that is fixed while the user is

dragging out a selection with the mouse.

</DL>

<DL>

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

</I></B>

<DD> Querys or sets the width of a the column <I>col</I></B> in the HList

widget. The value of <I>col</I></B> is zero-based: 0 stands for the first

column, 1 stands for the second, and so on. If no further parameters

are given, returns the current width of this column (in number of

pixels). Additional parameters can be given to set the width of this

column:

<DT> <I>pathName <B>indicator <I>option</I></B> entryPath ?<I>args ...</I></B>?

</I></B>

<DD> Manipulates the indicator on the list entries. An indicator is usually

a small display item (such as an image) that is displayed to the left

to an entry to indicate the status of the entry. For example, it may

be used to indicator whether a directory is opened or

closed. <I>option</I></B> can be one of the following:

<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>indicator create</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>indicator create</B></I> widget command when this display item

was created.

the entry given <I>entryPath</I></B>. The first two elements of the list

give the x and y coordinates of the upper-left corner of the screen

area covered by the entry (specified in pixels relative to the widget)

and the last two elements give the lower-right corner of the area, in

pixels. If no part of the entry given by index is visible on the

screen then the result is an empty string; if the entry is partially
