treeview - Create and manipulate hierarchical table widgets
<H3><A NAME="M3">SYNOPSIS</A></H3>
<B>treeview</B> <I>pathName </I>?<I>options</I>?<BR>
<H3><A NAME="M4">DESCRIPTION</A></H3>
The <B>treeview</B> widget displays a <B><A HREF="../TclCmd/tree.htm">tree</A></B> of data and provides
data sharing (via <I>tree data objects</I>) and the ability to tag
nodes.
<H3><A NAME="M5">INTRODUCTION</A></H3>
The <B>treeview</B> widget is used to display hierarchical data. Data is
represented as nodes in a general-ordered tree. Each node may have
sub-nodes and these nodes can in turn has their own children.
<P>
A node is displayed as a row entry in the widget. Each entry has a
text label and icon. When a node has children, its entry is drawn
with a small button to the left of the label. Clicking the mouse over
this button opens or closes the node. When a node is <I>open</I>, its
children are exposed. When it is <I>closed</I>, the children and their
descedants are hidden. The button is normally a <B>+</B> or
<B>-</B> symbol (ala Windows Explorer), but can be replaced with a
pair of Tk images (open and closed images).
<P>
If the node has data associated with it, they can be displayed in
columns running vertically on either side the tree.
Data may be set using an entries <B>-data</B> option,the <B>entry set</B>
subcommand, or via the <B><A HREF="../TclCmd/tree.htm">tree</A></B> data object.
You can control
the color, font, etc of each entry. Any entry label or data field can
be edited in-place.
<H3><A NAME="M6">TREE DATA OBJECT</A></H3>
The tree is not stored inside the widget but in a tree data object
(see the <B><A HREF="../TclCmd/tree.htm">tree</A></B> command for a further explanation). Tree data
objects can be shared among different clients, such as a
<B>treeview</B> widget or the <B><A HREF="../TclCmd/tree.htm">tree</A></B> command. You can walk the
tree and manage its data with the <B><A HREF="../TclCmd/tree.htm">tree</A></B> command tree, while
displaying it with the <B>treeview</B> widget. Whenever the tree is
updated, the <B>treeview</B> widget is automatically redrawn.
<P>
By default, the <B>treeview</B> widget creates its own internal tree object
and this initially contains just a root node. But if you wish
to share a tree, you can
created one with the <B><A HREF="../TclCmd/tree.htm">tree</A></B> command and set it via the <B>-tree</B>
configuration option. <B>Treeview</B> widgets can share this tree
object, and even display a sub-node as the root of the tree.
<P>
A tree object has both a Tcl and C API. You can insert or delete
nodes using <B>treeview</B> widget or <B><A HREF="../TclCmd/tree.htm">tree</A></B> command operations,
but also from C code. For example, you can load the tree from your C
code while still managing and displaying the tree from Tcl. The widget
is automatically notified whenever the tree is modified via C or Tcl.
<H3><A NAME="M7">SYNTAX</A></H3>
<dl><dd><table border="0"><tr><td><p style="font-size:12px;padding-left:.5em;padding-right:.5em;"><B>treeview </B><I>pathName </I>?<I>option value</I>?...</table></dl>
The <B>treeview</B> command creates a new window <I>pathName</I> and
makes it into a <B>treeview</B> widget. At the time this command is
invoked, there must not exist a window named <I>pathName</I>, but
<I>pathName</I>'s parent must exist. Additional options may be
specified on the command line or in the option database to configure
aspects of the widget such as its colors and font. See the
<B>configure</B> operation below for the exact details about what
<I>option</I> and <I>value</I> pairs are valid.
<P>
If successful, <B>treeview</B> returns the path name of the widget. It
also creates a new Tcl command by the same name. You can use this
command to invoke various operations that query or modify the widget.
The general form is:
<dl><dd><table border="0"><tr><td><p style="font-size:12px;padding-left:.5em;padding-right:.5em;"><I>pathName operation</I> ?<I>arg</I>?...</table></dl>
Both <I>operation</I> and its arguments determine the exact behavior of
the command. The operations available are described in the
section.
<H3><A NAME="M8">IDS AND TAGS</A></H3>
Nodes can be inserted into a tree using the <B>treeview</B> widget
<PRE>blt::treeview .t
set node [.t insert end root "one"]</PRE>
or <B><A HREF="../TclCmd/tree.htm">tree</A></B> command.
<PRE>set tree [blt::tree create]
set node [$tree insert root "one"]</PRE>
In both cases, a number identifying the node is returned (the value of
<B>$node</B>). This serial number or <I>id</I> uniquely identifies
the node. Please note that you can't infer a location or position of
a node from its id. The only exception is that the root node is
always id <B>0</B>. Since nodes may have the same labels or be moved
within the tree, ids provide an convenient way to identify nodes. If
a tree is shared, the ids will be the same regardless if you are using
by the <B>treeview</B> widget or the <B><A HREF="../TclCmd/tree.htm">tree</A></B> command. Ids are
recycled when the node deleted.
<P>
A node may also have any number of <I>tags</I> associated with it. A
tag is just a string of characters, and it may take any form except
that of an integer. For example, "<B>x123</B>" is valid, but
"<B>123</B>" isn't. The same tag may be associated with many
different nodes. This is typically done to associate a group of
nodes. Many operations in the <B>treeview</B> widget take either node
ids or tag names as arguments. Using a tag says to apply the operation
to all nodes with that tag.
<P>
The tag <B>all</B> is implicitly associated with every node in
the tree. It may be used to invoke operations on all the nodes in the
tree.
<P>
Commands that take a <I>tagnode</I>
will also accept a list of zero or more integer node numbers.
A node-list must contain only integers,
and the list can not have any leading spaces.
Node lists can simplify the use of iterating commands.
Tags and taglist are more widely used in tree than in treeview.
<P>
Tags may be shared, just like trees, between clients. For example,
you can use the tags created by the <B><A HREF="../TclCmd/tree.htm">tree</A></B> command with
<B>treeview</B> widgets.
<H3><A NAME="M9">SPECIAL NODE IDS</A></H3>
There are also several special non-numeric ids. Special ids differ
from tags in that they are always translated to their numeric
equivalent. They also take precedence over tags. For example, you
can't use a tag name that is a special id. These ids are specific to
the <B>treeview</B> widget.
<P>
<DL class="special node ids">
<DT><A NAME="M10"><B>active</B></A><DD>
The node where the mouse pointer is currently located.
When a node is active, it is drawn using its active icon
(see the <B>-activeicon</B> option).
The <B>active</B> id is changed automatically by moving the mouse
pointer over another node or by using the <B>entry activate</B>
operation. Note that there can be only one active node at a time.
<P><DT><A NAME="M11"><B>anchor</B></A><DD>
The node representing the fixed end of the current selection.
The anchor is set by the <B><A HREF="../TkCmd/selection.htm">selection anchor</A></B> operation.
<P><DT><A NAME="M12"><B>bottom</B></A><DD>
The last viewable node.
<P><DT><A NAME="M13"><B>current</B></A><DD>
The node where the mouse pointer is currently located.
But unlike <B>active</B>, this id changes while the
selection is dragged. It is used to determine the
current node during button drags.
<P><DT><A NAME="M14"><B>down</B></A><DD>
The next open node from the current focus. The <B>down</B> of
the last open node is the same.
<P><DT><A NAME="M15"><B>end</B></A><DD>
The last node at depth 1 in tree.
<P><DT><A NAME="M16"><B>focus</B></A><DD>
The node that currently has focus. When a node has focus,
it receives key events. To indicate focus, the node
is drawn with a dotted line around its label. You can change the
focus using the <B><A HREF="../TkCmd/focus.htm">focus</A></B> operation.
<P><DT><A NAME="M17"><B>last</B></A><DD>
Same as <B>tail</B>.
<P><DT><A NAME="M18"><B>mark</B></A><DD>
The node representing the non-fixed end of the current selection.
The mark is set by the <B><A HREF="../TkCmd/selection.htm">selection mark</A></B> operation.
<P><DT><A NAME="M19"><B>next</B></A><DD>
The next open node from the current focus. But unlike <B>down</B>,
when the focus is on last open node, <B><A HREF="../TclCmd/next.htm">next</A></B> wraps around to the
root node.
<P><DT><A NAME="M20"><B>nextsibling</B></A><DD>
The next sibling from the node with the current focus. If the node
is already the last sibling then it is the <B>nextsibling</B>.
<P><DT><A NAME="M21"><B>parent</B></A><DD>
The parent of the node with the current focus. The <B>parent</B>
of the root is also the root.
<P><DT><A NAME="M22"><B>prev</B></A><DD>
The last open node from the current focus. But unlike <B>up</B>,
when the focus is at root, <B>last</B> wraps around to the last
open node in the tree.
<P><DT><A NAME="M23"><B>prevsibling</B></A><DD>
The previous sibling from the node with the current focus. If the node
is already the first sibling then it is the <B>prevsibling</B>.
<P><DT><A NAME="M24"><B>root</B></A><DD>
The root node. You can also use id <B>0</B> to indicate
the root.
<P><DT><A NAME="M25"><B>tail</B></A><DD>
The last node in the tree, viewable or not.
<P><DT><A NAME="M26"><B>top</B></A><DD>
The first node.
<P><DT><A NAME="M27"><B>up</B></A><DD>
The last open node (in depth-first order) from the current focus. The
<B>up</B> of the root node (i.e. the root has focus) is also the root.
<P><DT><A NAME="M28"><B>view.top</B></A><DD>
First node that's current visible in the widget.
<P><DT><A NAME="M29"><B>view.bottom</B></A><DD>
Last node that's current visible in the widget.
<P><DT><A NAME="M30"><B>@</B><I>x</I><B>,</B><I>y</I></A><DD>
Indicates the node that covers the point in the treeview window
specified by <I>x</I> and <I>y</I> (in pixel coordinates). If no
part of the entryd covers that point, then the closest node to that
point is used.
<P><DT><A NAME="M31"><B>@</B><I>ID</I><B>-></B><I>LABEL</I>-><I>LABEL</I>...</A><DD>
Lookup via node labels, eg. <I>0->Main->Users</I>.
Quotes can be used around labels that use reserved words or contain
spaces, eg. <I>0->"Main"->'User Groups'</I>.
See the <B><A HREF="../TclCmd/tree.htm">tree</A></B> man page for more details.
<P></DL>
<P>
A node may be specified as an id or tag. If the specifier is an
integer then it is assumed to refer to the single node with that id.
If the specifier is not an integer, it's checked to see if it's a
special id (such as focus). Otherwise, it's assumed to be tag. Some
operations only operate on a single node at a time; if a tag refers to
more than one node, then an error is generated.
<H3><A NAME="M32">DATA FIELDS</A></H3>
A node in the tree can have <I>data field</I>. A data field is a
name-value pair, used to represent arbitrary data in the node. Nodes
can contain different fields (they aren't required to contain the same
fields). You can optionally display these fields in the
<B>treeview</B> widget in columns running on either side of the
displayed tree. A node's value for the field is drawn in the column
along side its node in the hierarchy. Any node that doesn't have a
specific field is left blank. Columns can be interactively resized,
hidden, or, moved.
<H3><A NAME="M33">ENTRY BINDINGS</A></H3>
You can bind Tcl commands to be invoked when events occur on nodes
(much like Tk canvas items). You can bind a node using its id or
its <I>bindtags</I>. Bindtags are simply names that associate a
binding with one or more nodes. There is a built-in tag <B>all</B>
that all node entries automatically have.
<H3><A NAME="M34">TREEVIEW OPERATIONS</A></H3>
The <B>treeview</B> operations are the invoked by specifying
the widget's pathname, the operation, and any arguments that pertain
to that operation. The general form is:
<P>
<PRE><I>pathName operation </I>?<I>arg arg ...</I>?</PRE>
<P>
<I>Operation</I> and the <I>arg</I>s determine the exact behavior of the
command. The following operation are available for <B>treeview</B> widgets:
<P>
<DL class="treeview operations">
<DT><A NAME="M35"><I>pathName </I><B>bbox</B> ?<B>-screen</B>? <I>tagOrId...</I></A><DD>
Returns a list of 4 numbers, representing a bounding box of around
the specified entries. The entries is given by one or more <I>tagOrId</I>
arguments.
If the <B>-screen</B> flag is given, then the x-y coordinates
of the bounding box are returned as screen coordinates, not
virtual coordinates. Virtual coordinates start from <B>0</B> from the
root node and include the title.
If the <B>-world</B> flag is given, then the y coordinate
the title height is added in.
The returned list contains the following values.
<P>
<DL class="treeview operations">
<DT><A NAME="M36"><I>x</I></A><DD>
X-coordinate of the upper-left corner of the bounding box.
<P><DT><A NAME="M37"><I>y</I></A><DD>
Y-coordinate of the upper-left corner of the bounding box.
<P><DT><A NAME="M38"><I>width</I></A><DD>
Width of the bounding box.
<P><DT><A NAME="M39"><I>height</I></A><DD>
Height of the bounding box.
<P></DL>
<P><DT><A NAME="M40"><I>pathName </I><B>bind</B> <I>tagName</I> ?<I>sequence command</I>?</A><DD>
Associates <I>command</I> with <I>tagName</I> such that whenever the
event sequence given by <I>sequence</I> occurs for a node with this
tag, <I>command</I> will be invoked. The syntax is similar to the
<B><A HREF="../TkCmd/bind.htm">bind</A></B> command except that it operates on <B>treeview</B> entries,
rather than widgets.
The <I>tagName</I> can be an entry or tag, or predefined tags such
as <B>all</B>, <B><A HREF="../TkCmd/entry.htm">Entry</A></B> or <B><A HREF="../TkCmd/button.htm">Button</A></B>.
See the <B><A HREF="../TkCmd/bind.htm">bind</A></B> manual entry for
complete details on <I>sequence</I> and the substitutions performed on
<I>command</I> before invoking it.
<P>
If all arguments are specified then a new binding is created, replacing
any existing binding for the same <I>sequence</I> and <I>tagName</I>.
If the first character of <I>command</I> is <B>+</B> then <I>command</I>
augments an existing binding rather than replacing it.
If no <I>command</I> argument is provided then the command currently
associated with <I>tagName</I> and <I>sequence</I> (it's an error occurs
if there's no such binding) is returned. If both <I>command</I> and
<I>sequence</I> are missing then a list of all the event sequences for
which bindings have been defined for <I>tagName</I>.
<P><DT><A NAME="M41"><I>pathName </I><B>button </B><I>operation</I> ?<I>args</I>?</A><DD>
This command is used to control the button selectors within a
<B>treeview</B> widget.
It has several forms, depending on <I>operation</I>:
<P>
<DL class="treeview operations">
<DT><A NAME="M42"><I>pathName </I><B>button activate</B> <I>tagOrId</I></A><DD>
Designates the node given by <I>tagOrId</I> as active.
When a node is active it's entry is drawn using its active icon
(see the <B>-activeicon</B> option).
Note that there can be only one active entry at a time.
The special id <B>active</B> indicates the currently active node.
<P><DT><A NAME="M43"><I>pathName </I><B>button bind</B> <I>tagName</I> ?<I>sequence command</I>?</A><DD>
Associates <I>command</I> with <I>tagName</I> such that whenever the
event sequence given by <I>sequence</I> occurs for an button of a
node entry with this tag, <I>command</I> will be invoked. The syntax is
similar to the <B><A HREF="../TkCmd/bind.htm">bind</A></B> command except that it operates on
<B>treeview</B> buttons, rather than widgets. See the <B><A HREF="../TkCmd/bind.htm">bind</A></B>
manual entry for complete details on <I>sequence</I> and the
substitutions performed on <I>command</I> before invoking it.
<P>
If all arguments are specified then a new binding is created, replacing
any existing binding for the same <I>sequence</I> and <I>tagName</I>.
If the first character of <I>command</I> is <B>+</B> then <I>command</I>
augments an existing binding rather than replacing it.
If no <I>command</I> argument is provided then the command currently
associated with <I>tagName</I> and <I>sequence</I> (it's an error occurs
if there's no such binding) is returned. If both <I>command</I> and
<I>sequence</I> are missing then a list of all the event sequences for
which bindings have been defined for <I>tagName</I>.
<P><DT><A NAME="M44"><I>pathName </I><B>button cget</B> <I>option</I></A><DD>
Returns the current value of the configuration option given
by <I>option</I>.
<I>Option</I> may have any of the values accepted by the <B>configure</B>
operation described below.
<P><DT><A NAME="M45"><I>pathName </I><B>button configure</B> ?<I>option</I>? ?<I>value option value ...</I>?</A><DD>
Query or modify the configuration options of the widget.
If no <I>option</I> is specified, returns a list describing all of
the available options for <I>pathName</I> (see <B><A HREF="../TkLib/ConfigWidg.htm">Tk_ConfigureInfo</A></B> for
information on the format of this list). If <I>option</I> is specified
with no <I>value</I>, 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> is specified). If
one or more <I>option-value</I> 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> and <I>value</I> are described in the section
below.
<P></DL>
<P><DT><A NAME="M46"><I>pathName </I><B>cget</B> <I>option</I></A><DD>
Returns the current value of the configuration option given
by <I>option</I>.
<I>Option</I> may have any of the values accepted by the <B>configure</B>
operation described below.
<P><DT><A NAME="M47"><I>pathName </I><B>close </B>?<B>-recurse</B>? ?<B>-trees</B>? <I>tagOrId...</I></A><DD>
Closes the node specified by <I>tagOrId</I>. In addition, if a Tcl
script was specified by the <B>-closecommand</B> option, it is
invoked. If the node is already closed, this command has no effect.
If the <B>-recurse</B> flag is present, each child node is
recursively closed.
The <B>-trees</B> flag is like <B>-recurse</B> but operates only on nodes
with children, excluding the <I>root</I>.
<P><DT><A NAME="M48"><I>pathName </I><B>column </B><I>operation</I> ?<I>args</I>?</A><DD>
The following operations are available for treeview columns.
<P>
<DL class="treeview operations">
<DT><A NAME="M49"><I>pathName </I><B>column activate</B> <I>column</I></A><DD>
Sets the active column to <I>column</I>. <I>Column</I> is the
name of a column in the widget.
When a column is active, it's drawn using its <B>-activetitlebackground</B>
and <B>-activetitleforeground</B> options. If <I>column</I> is the <B>""</B>,
then no column will be active. If no column argument is provided, then
the name of the currently active column is returned.
<P><DT><A NAME="M50"><I>pathName </I><B>column bbox</B> <I>column entry</I></A><DD>
Returns a list of 4 numbers, representing a bounding box of around

Associates <I>command</I> with <I>column</I> such that whenever the
event sequence given by <I>sequence</I> occurs for a column
node entry with this tag, <I>command</I> will be invoked. The syntax is
similar to the <B><A HREF="../TkCmd/bind.htm">bind</A></B> command except that it operates on
<B>treeview</B> colunns, rather than widgets. See the <B><A HREF="../TkCmd/bind.htm">bind</A></B>

substitutions performed on <I>command</I> before invoking it.
<P><DT><A NAME="M52"><I>pathName </I><B>column cget</B> <I>name</I> <I>option</I></A><DD>
Returns the current value of the column configuration option given
by <I>option</I> for <I>name</I>. <I>Name</I> is the name of column
that corresponds to a data field.
<I>Option</I> may have any of the values accepted by the <B>configure</B>
operation described below.

<P><DT><A NAME="M55"><I>pathName </I><B>column delete</B> <I>field</I> ?<I>field</I>...?</A><DD>
Deletes one of more columns designated by <I>field</I>.
Requests to delete the tree column are silently ignored.
Note that this does not delete the data fields themselves.
<P><DT><A NAME="M56"><I>pathName </I><B>column index</B> <I>index</I></A><DD>
Return the integer for index. May use "end" or "end-N".

Inserts one (or more) columns designated by <I>field</I>.
A column displays
each entry node's data field using this name. If the node doesn't
define the given field, the cell is left blank.
<I>Position</I>
indicates where in the list of columns to add the new column. It may be
either a name, a number or <B>end</B>.
If multiple <I>fields</I> are given, they may not start with a dash.
If <I>field</I> is the empty string or <B>#auto</B>,
a name is generated prefixed by the string <B>Col</B> plus a unique integer.
If <I>field</I> ends with <B>#auto</B>, the generated name uses it's prefix
instead.
The returned values is the created column names.
Note that the predefined tree column (ie. <I>BLT-TreeView</I>)
is aliased by <I>Col0</I>.

<P>
The result of each eval gets appended to the return list, unless
the script issues a CONTINUE, in which case that node is skipped.

<P><DT><A NAME="M161"><I>pathName </I><B>insert</B> ?<B>-node </B><I>num</I>? ?<B>-at </B><I>tagOrId</I>? ?<B>-styles </B><I>styleslist</I>? ?<B>-tags </B><I>tagslist</I>? <I>position</I> ?<I>path</I>? ?<I>options...</I>? ?<I>path</I>? ?<I>options...</I>?</A><DD>
Inserts one or more nodes at <I>position</I>. <I>Position</I> is the
location (number or <B>end</B>) where the new nodes are added to
the parent node. <I>Path</I> is the pathname of the new node.
Pathnames can be formatted either as a Tcl list (each element is a path
component) or as a string separated by a special character sequence
(using the <B>-separator</B> option). Pathnames are normally
absolute, but the <B>-at</B> switch lets you select a relative
starting point. Its value is the id of the starting node.
<P>
If <I>path</I> name and options are ommitted, <I>path</I>
will default to <I>#auto</I>.
<P>
A <I>path</I> name of <I>#auto</I> attempts to use
the tree node name as the <I>path</I> name.
For large flat trees setting <B>-allowduplicates</B> to true
can greatly speedup loading #auto as it avoids checking overhead.
This is the fastest way to bulk load large numbers of nodes
(next to using <B>-tree</B>).
<P>
If the last component of a <I>path</I> name
ends in <I>#auto</I>, the path is
generated using the string prefix (before #auto)
followed by a sequential number unique within the
parent, eg. <B>.t insert end {users u#auto}</B>.
<P>
The <B>-node</B> switch lets you specify a tree node number
directly instead of having one generating automatically.
For multi-node inserts, the node number is incremented.
<P>
The <B>-styles</B> switch specifies a list of column/stylename
pairs to set for elements of the <B>-data</B> option.
<P>
The <B>-tags</B> switch specifies a list of tags to add
to the new entries.
<P>
Note that all ancestors of the new node must already exist, unless the
<B>-autocreate</B> option is set. It is also an error if a node
already exists, unless the <B>-allowduplicates</B> option is set.
<P>
The <I>option</I> and <I>value</I> arguments
may have any of the values accepted by the
<B>entry configure</B> operation described in the
section below. The returned value is list of ids for
the new entries.
<P><DT><A NAME="M162"><I>pathName </I><B>move </B><I>tagnode</I> <I>how</I> <I>destId</I></A><DD>
Moves the node(s) given by <I>tagnode</I> to the destination node. The
node can not be an ancestor of the destination. <I>DestId</I> is
the id of the destination node and can not be the root of the
tree. In conjunction with <I>how</I>, it describes how the move is
performed.
<P>
<DL class="treeview operations">
<DT><A NAME="M163"><B>before</B></A><DD>
Moves the node before the destination node.
<P><DT><A NAME="M164"><B>after</B></A><DD>
Moves the node after the destination node.
<P><DT><A NAME="M165"><B>into</B></A><DD>
Moves the node to the end of the destination's list of children.
<P></DL>
<P><DT><A NAME="M166"><I>pathName </I><B>nearest</B> ?<B>-root</B>? ?<B>-strict</B>? <I>x y</I> ?<I>varName</I>?</A><DD>
Returns the id of the node entry closest to the given X-Y screen
coordinate. If the coordinate is not directly over any node, then the
nearest node is returned. If the argument <I>varName</I> is present,
this is a Tcl variable that is set to either <B><A HREF="../TkCmd/button.htm">button</A></B>,
<B>icon</B>, <B><A HREF="../TkCmd/label.htm">label</A></B>, <B>title</B>, <B>titlelabel</B>, <B>titleicon</B>, <B>datalabel</B>, <B>dataicon</B>, or <B>""</B> depending what part of the
entry the coordinate lies.
The -root option subtracts the windows root from the coordinates.
The -strict option fails the match if not directly
over a node, eg. in the title or past end of last row.
<P><DT><A NAME="M167"><I>pathName </I><B>open </B>?<B>-recurse</B>? ?<B>-trees</B>? <I>tagnode...</I></A><DD>
Opens the one or more nodes specified by <I>tagnode</I>.
If a node is not already open, the Tcl script specified by the
<B>-opencommand</B> option is invoked. If the <B>-recurse</B> flag
is present, then each descendant is recursively opened.
The <B>-trees</B> flag is like <B>-recurse</B> but operates only on nodes
with children.
<P><DT><A NAME="M168"><I>pathName </I><B>range</B> ?<B>-open</B>? <I>first last</I></A><DD>
Returns the ids in depth-first order of the nodes
between the <I>first</I> and <I>last</I> ids. If the <B>-open</B>
flag is present, it indicates to consider only open nodes.
If <I>last</I> is before <I>first</I>, then the ids are
returned in reverse order.
<P><DT><A NAME="M169"><I>pathName </I><B>scan</B> <I>option args</I></A><DD>
This command implements scanning. It has
two forms, depending on <I>option</I>:
<P>
<DL class="treeview operations">
<DT><A NAME="M170"><I>pathName </I><B>scan mark </B><I>x y</I></A><DD>
Records <I>x</I> and <I>y</I> and the current view in the treeview
window; used in conjunction with later <B>scan dragto</B> commands.
Typically this command is associated with a mouse button press in
the widget. It returns an empty string.
<P><DT><A NAME="M171"><I>pathName </I><B>scan dragto </B><I>x y</I>.</A><DD>
Computes the difference between its <I>x</I> and <I>y</I>
arguments and the <I>x</I> and <I>y</I> arguments to the last
<B>scan mark</B> command for the widget.
It then adjusts the view by 10 times the
difference in coordinates. This command is typically associated
with mouse motion events in the widget, to produce the effect of
dragging the list at high speed through the window. The return
value is an empty string.
<P></DL>
<P><DT><A NAME="M172"><I>pathName </I><B>see</B> ?<B>-anchor </B><I>anchor</I>? <I>tagOrId</I></A><DD>
Adjusts the view of entries so that the node given by <I>tagOrId</I> is
visible in the widget window. It is an error if <B>tagOrId</B> is a
tag that refers to more than one node. The node's position
on the screen can be set using the
<B>-anchor</B> flag. Its value is a Tk anchor position: <B>n, c, s</B>.
<P><DT><A NAME="M173"><I>pathName </I><B>selection </B><I>option arg</I></A><DD>
This command is used to adjust the selection within a <B>treeview</B>
widget. It has several forms, depending on <I>option</I>:
<P>
<DL class="treeview operations">
<DT><A NAME="M174"><I>pathName </I><B>selection anchor ?</B><I>tagOrId</I>? ?<I>column</I>?</A><DD>
Sets the selection anchor to the node given by <I>tagOrId</I>.
If <I>tagOrId</I> refers to a non-existent node, then the closest
node is used.
The selection anchor is the end of the selection that is fixed
while dragging out a selection with the mouse.
The special id <B>anchor</B> may be used to refer to the anchor
node. With no arguments, returns anchor entry and column if any.
<P><DT><A NAME="M175"><I>pathName </I><B>selection cells</B></A><DD>
Returns pairs of nodes and columns for all selected cells.
The -selectmode must be <I>cell</I> or <I>multicell</I>.
<P><DT><A NAME="M176"><I>pathName </I><B>selection clear </B><I>first </I>?<I>last</I>? ?<I>column</I>?</A><DD>
Removes the entries between <I>first</I> and <I>last</I>
(inclusive) from the selection. Both <I>first</I> and
<I>last</I> are ids representing a range of entries.
If <I>last</I> isn't given, then only <I>first</I> is deselected.
Entries outside the selection are not affected.
<P><DT><A NAME="M177"><I>pathName </I><B>selection clearall</B></A><DD>
Clears the entire selection.
<P><DT><A NAME="M178"><I>pathName </I><B>selection mark </B><I>tagOrId</I> ?<I>column</I>?</A><DD>
Sets the selection mark to the node given by <I>tagOrId</I>. This
causes the range of entries between the anchor and the mark to be
temporarily added to the selection. The selection mark is the end of
the selection that is fixed while dragging out a selection with the
mouse. The special id <B>mark</B> may be used to refer to the current
mark node.
If <I>tagOrId</I> refers to a non-existent node, then the mark
is ignored.
Resetting the mark will unselect
the previous range. Setting the anchor finalizes the range.
<P><DT><A NAME="M179"><I>pathName </I><B>selection includes </B><I>tagOrId</I> ?<I>column</I>?</A><DD>
Returns 1 if the node given by <I>tagOrId</I> is currently
selected, 0 if it isn't.
<P><DT><A NAME="M180"><I>pathName </I><B>selection present</B></A><DD>
Returns 1 if any nodes are currently selected and 0 otherwise.
<P><DT><A NAME="M181"><I>pathName </I><B>selection set </B><I>first </I>?<I>last</I>? ?<I>column</I>?</A><DD>
Selects all of the nodes in the range between
<I>first</I> and <I>last</I>, inclusive, without affecting
the selection state of nodes outside that range.
<P><DT><A NAME="M182"><I>pathName </I><B>selection toggle </B><I>first </I>?<I>last</I>? ?<I>column</I>?</A><DD>
Selects/deselects nodes in the range between
<I>first</I> and <I>last</I>, inclusive, from the selection.
If a node is currently selected, it becomes deselected, and
visa versa.
<P></DL>
<P><DT><A NAME="M183"><I>pathName </I><B>show </B>?<B>flags</B>? <I>tagOrId</I>...</A><DD>
Un-hide nodes matching the criteria given by <I>flags</I>.
If no <I>tagOrId</I> are given, traverses entire tree.
The <I>flags</I> are the same as for the <B>hide</B> command.
<P><DT><A NAME="M184"><I>pathName </I><B>sort</B> ?<I>operation</I>? <I>args...</I></A><DD>
<P>
<DL class="treeview operations">
<DT><A NAME="M185"><I>pathName </I><B>sort auto</B> ?<I>boolean</I></A><DD>
Turns on/off automatic sorting of node entries. If <I>boolean</I> is
true, entries will be automatically sorted as they are opened,
closed, inserted, or deleted. If no <I>boolean</I> argument is
provided, the current state is returned.
<P><DT><A NAME="M186"><I>pathName </I><B>sort cget</B> <I>option</I></A><DD>
Returns the current value of the configuration option given
by <I>option</I>.
<I>Option</I> may have any of the values accepted by the <B>configure</B>
operation described below.
<P><DT><A NAME="M187"><I>pathName </I><B>sort configure</B> ?<I>option</I>? ?<I>value option value ...</I>?</A><DD>
Query or modify the sorting configuration options of the widget.
If no <I>option</I> is specified, returns a list describing all of
the available options for <I>pathName</I> (see <B><A HREF="../TkLib/ConfigWidg.htm">Tk_ConfigureInfo</A></B> for
information on the format of this list). If <I>option</I> is specified
with no <I>value</I>, 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> is specified). If
one or more <I>option-value</I> pairs are specified, then the command
modifies the given sorting option(s) to have the given value(s); in
this case the command returns an empty string.
<I>Option</I> and <I>value</I> are described below:
<P>
<DL class="treeview operations">
<DT><A NAME="M188"><B>-column</B><I> string</I></A><DD>
Specifies the column to sort. Entries in the widget are rearranged
according to this column. If <I>column</I> is <B>""</B> then
no sort is performed.
<P><DT><A NAME="M189"><B>-command</B><I> string</I></A><DD>
Specifies a Tcl procedure to be called when sorting nodes.
The procedure is called with three arguments: the pathname of the widget
and the fields of two entries. The procedure returns 1 if the first
node is greater than the second, -1 is the second is greater, and 0
if equal.
<P><DT><A NAME="M190"><B>-decreasing</B><I> boolean</I></A><DD>
Indicates to sort in ascending/descending order. If <I>boolean</I>
is true, then the entries as in descending order. The default is
<B>no</B>.
<P><DT><A NAME="M191"><B>-mode</B><I> string</I></A><DD>
Specifies how to compare entries when sorting. <I>String</I>
may be one of the following:

Use string comparison based upon the ASCII collation order.
<P><DT><A NAME="M194"><B>dictionary</B></A><DD>
Use dictionary-style comparison. This is the same as <B>ascii</B>
except (a) case is ignored except as a tie-breaker and (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".
<P><DT><A NAME="M195"><B>integer</B></A><DD>
Compares fields as integers.

<P><DT><A NAME="M200"><I>pathName </I><B>style </B><I>operation</I> ?<I>args</I>?</A><DD>
Styles control how data is to be rendered by the widget.
They are created with the <B>create</B> subcommands (described below)
A default style name <B><A HREF="../TkCmd/text.htm">text</A></B> is builtin. It is of type
<I>textbox</I> and is used as the default style for columns.
Styles may also be applied to entries, individual cells or
widget options. For example, the <B>-altstyle</B> option applies a style to
every second visible row entry while the
<B>-levelstyles</B> option can specify a different style for each node level.
<P>
The following operations are available for treeview styles.
<P>
<DL class="treeview operations">

<P><DT><A NAME="M217"><I>pathName </I><B>tag </B><I>operation args</I></A><DD>
Tags are a general means of selecting and marking nodes in the tree.
A tag is just a string of characters, and it may take any form except
that of an integer. The same tag may be associated with many
different nodes.
<P>
Both <I>operation</I> and its arguments determine the exact behavior of
the command. The operations available for tags are listed below.

<DL class="treeview operations">
<DT><A NAME="M226"><I>pathName </I><B>xview</B></A><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 .2 and the second element is .6,
20% of the <B>treeview</B> widget's text is off-screen to the left,
the middle 40% is visible
in the window, and 40% of the text is off-screen to the right.
These are the same values passed to scrollbars via the <B>-xscrollcommand</B>
option.

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

between 0 and 1.
The first element gives the position of the node at the
top of the window, relative to the widget as a whole (0.5 means
it is halfway through the treeview window, for example).
The second element gives the position of the node just after
the last one in the window, relative to the widget as a whole.
These are the same values passed to scrollbars via the <B>-yscrollcommand</B>
option.
<P><DT><A NAME="M232"><I>pathName </I><B>yview</B> <I>tagOrId</I></A><DD>
Adjusts the view in the window so that the node given by
<I>tagOrId</I> is displayed at the top of the window.
<P><DT><A NAME="M233"><I>pathName </I><B>yview moveto</B><I> fraction</I></A><DD>
Adjusts the view in the window so that the node given by <I>fraction</I>
appears at the top of the window.
<I>Fraction</I> is a fraction between 0 and 1; 0 indicates the first
node, 0.33 indicates the node one-third the
way through the <B>treeview</B> widget, and so on.
<P><DT><A NAME="M234"><I>pathName </I><B>yview scroll </B><I>number what</I></A><DD>
This command adjusts the view in the window up or down according to
<I>number</I> and <I>what</I>.
<I>Number</I> must be an integer.
<I>What</I> must be either <B>units</B> or <B>pages</B>.
If <I>what</I> is <B>units</B>, the view adjusts up or down by
<I>number</I> lines; if it is <B>pages</B> then
the view adjusts by <I>number</I> screenfuls.
If <I>number</I> is negative then earlier nodes
become visible; if it is positive then later nodes
become visible.

<H3><A NAME="M235">TREEVIEW EDITING</A></H3>
A column of data is editable when its <B>-edit</B> option is set to True
For column 0, edit changes an entries <I>-label</I> option.
For all other columns, edit will update the <I>-data</I> fields.
Tree data traces can also be used for edit control.
Most of the following applies to textbox styles.
However, combobox and checkbox also generate <<TreeViewEditStart/End>> events
while barbox and windowbox are not editable.
<P>
Text editing is aborted with <Escape> and finished with <Return>.
A newline may be inserted with a <Control-r>.
Native Tk widgets are now used for builtin editing, using the
path <B>$w.edit</B>.
By default an <B><A HREF="../TkCmd/entry.htm">entry</A></B> widget will be used, however, column editing options
can be changed via <B>-editopts</B>
and <B>-validatecmd</B>. Moreover, columns with a combobox style
can provide popup list of options in a listbox
using the following style options: <B>-choices, -choicecmd -choiceicons</B>
Two virtual events can be used to gain control the during edit:
<I><<TreeViewEditStart>></I> and <I><<TreeViewEditEnd>></I>.
The column index is passed in %x, and the entry-row index is passed in %y.
eg.
<PRE>treeview .t
bind .t <<TreeViewEditStart>> {EditStart %W %x %y}
bind .t <<TreeViewEditEnd>> {EditEnd %W %x %y}</PRE>
These gain control at the start and end of editing respectively,
and are general alternatives to <I>-editopts</I> -startcmd and -endcmd.
For further details see <I>EditCell</I> in
<B>$blt_library/treeview.tcl</B>.
<H3><A NAME="M236">TREEVIEW OPTIONS</A></H3>

<H3><A NAME="M330">ENTRY OPTIONS</A></H3>
Many widget configuration options have counterparts in entries. For
example, there is a <B>-closecommand</B> configuration option for both
widget itself and for individual entries. Options set at the widget
level are global for all entries. If the entry configuration option
is set, then it overrides the widget option. This is done to avoid
wasting memory by replicated options. Most entries will have
redundant options.
<P>
There is no resource class or name for entries.
<P>
<DL class="entry options">
<DT><A NAME="M331"><B>-activeicons </B><I>images</I></A><DD>

<P><DT><A NAME="M356"><B>-style </B><I>stylename</I></A><DD>
Set the style to use for the entry. This will override the column
style, just as <I>style set</I> will override an entry style.
This is useful mostly for seting bg/fg/font
for a row. Other options may or may not do nothing.
Note, setting icon in a style will apply to all value
columns, but not the tree column.
<P><DT><A NAME="M357"><B>-sublabel </B><I>string</I></A><DD>
Sets the text for the entry's sub-label to be displayed to the right

A windowbox style can be applied to either columns or cells.
Setting a windowbox type style for an entry is silently ignored.
When the cell containing a window style is displayed, the subwindow is
taken over and managed as a slave (see <I>style slaves</I>).
If a given windowbox style does not define <I>-windowcmd</I>, then the cell data
is assumed to contain the widget name to use.
If that data does not describe a valid window it is silently ignored and

<H3><A NAME="M496">DEFAULT BINDINGS</A></H3>
Tk automatically creates class bindings for treeviews that give them
Motif-like behavior. Much of the behavior of a <B>treeview</B> widget is determined
by its <B>-selectmode</B> option, which selects one of two ways
of dealing with the selection.
<P>
If the selection mode is <B>single</B>, only one node can be
selected at a time.
Clicking button 1 on an node selects
it and deselects any other selected item.
<P>
If the selection mode is <B>multiple</B>,
any number of entries may be selected at once, including discontiguous
ranges. Clicking Control-Button-1 on a node entry
toggles its selection state without affecting any other entries.
Pressing Shift-Button-1 on a node entry selects
it, extends the selection.
<P>
<DL class="default bindings">
<DT>[0]<DD>
The virtual event <<TreeViewFocusEvent>> is generated for each
keyboard and mouse initiated change in focus. It is up to
the user to determine if the focus actually changed.
<P><DT>[1]<DD>
In <B>extended</B> mode, the selected range can be adjusted by pressing
button 1 with the Shift key down: this modifies the selection to
consist of the entries between the anchor and the entry under
the mouse, inclusive.
The un-anchored end of this new selection can also be dragged with
the button down.
<P><DT>[2]<DD>
In <B>extended</B> mode, pressing button 1 with the Control key down
starts a toggle operation: the anchor is set to the entry under
the mouse, and its selection state is reversed. The selection state
of other entries isn't changed.
If the mouse is dragged with button 1 down, then the selection state
of all entries between the anchor and the entry under the mouse
is set to match that of the anchor entry; the selection state of
all other entries remains what it was before the toggle operation
began.
<P><DT>[3]<DD>
If the mouse leaves the treeview window with button 1 down, the window
scrolls away from the mouse, making information visible that used
to be off-screen on the side of the mouse.
The scrolling continues until the mouse re-enters the window, the
button is released, or the end of the hierarchy is reached.
<P><DT>[4]<DD>
Mouse button 2 may be used for scanning.
If it is pressed and dragged over the <B>treeview</B> widget, the contents of
the hierarchy drag at high speed in the direction the mouse moves.
<P><DT>[5]<DD>
If the Up or Down key is pressed, the location cursor (active
entry) moves up or down one entry, as does Control-p and Control-n.
If the selection mode is <B>browse</B> or <B>extended</B> then the
new active entry is also selected and all other entries are
deselected.
In <B>extended</B> mode the new active entry becomes the
selection anchor.
<P><DT>[6]<DD>
In <B>extended</B> mode, Shift-Up and Shift-Down move the location
cursor (active entry) up or down one entry and also extend
the selection to that entry in a fashion similar to dragging
with mouse button 1.
<P><DT>[7]<DD>
The Left and Right keys scroll the <B>treeview</B> widget view left and right
by the width of the character <B>0</B>.
Control-Left and Control-Right scroll the <B>treeview</B> widget view left and
right by the width of the window.
<P><DT>[8]<DD>
The Prior and Next keys scroll the <B>treeview</B> widget view up and down
by one page (the height of the window), as does Control-u and Control-d.
<P><DT>[9]<DD>
The Home and End keys scroll the <B>treeview</B> widget horizontally to
the left and right edges, respectively.
<P><DT>[10]<DD>
Control-Home sets the location cursor to the first entry,
selects that entry, and deselects everything else
in the widget.
<P><DT>[11]<DD>
Control-End sets the location cursor to the last entry,
selects that entry, and deselects everything else
in the widget.
<P><DT>[12]<DD>
In <B>extended</B> mode, Control-Shift-Home extends the selection
to the first entry and Control-Shift-End extends
the selection to the last entry.
<P><DT>[13]<DD>
In <B>multiple</B> mode, Control-Shift-Home moves the location cursor
to the first entry and Control-Shift-End moves
the location cursor to the last entry.
<P><DT>[14]<DD>
The space and Select keys make a selection at the location cursor
(active entry) just as if mouse button 1 had been pressed over
this entry.
<P><DT>[15]<DD>
In <B>extended</B> mode, Control-Shift-space and Shift-Select
extend the selection to the active entry just as if button 1
had been pressed with the Shift key down.
<P><DT>[16]<DD>
In <B>extended</B> mode, the Escape key cancels the most recent
selection and restores all the entries in the selected range
to their previous selection state.
<P><DT>[17]<DD>
Control-slash selects everything in the widget, except in
<B>single</B> and <B>browse</B> modes, in which case it selects
the active entry and deselects everything else.
<P><DT>[18]<DD>
Control-backslash deselects everything in the widget, except in
<B>browse</B> mode where it has no effect.
<P><DT>[19]<DD>
The F16 key (labelled Copy on many Sun workstations) or Meta-w
copies the selection in the widget to the clipboard, if there is
a selection.

TreeFill is a utility function to simplify tree data loading
from a human-readable string. The string
uses line indentation to indicate tree depth.
The indentation is in multiples of 4 spaces, relative to the first line. eg.
<PRE>pack [treeview .t]
.t column insert end X Y Z
blt::tv::TreeFill .t {
A 1 2 3
B 4 5 6
x 7 8 9
y 10 11 12
a 1 2 "Level a"
b 1 2 "Level b"
C 1 2 3
}
.t open -trees all
.t entry conf 0->B->y->a -state disabled</PRE>
Any column names not defined are generated.
To load a table instead of a tree, simply set the -flat option first. eg.
<PRE>pack [treeview .t -flat 1]
.t column conf Col0 -hide 1
.t column insert end Name Age Sex
blt::tv::TreeFill .t {
"Tom Brown" 9 M
"Mike Small" 8 M
"Tina Baker" 7 F
}</PRE>
<H3><A NAME="M563">EXAMPLE</A></H3>
The <B>treeview</B> command creates a new widget.
<PRE>treeview .h -bg white</PRE>
A new Tcl command <B>.h</B> is also created. This command can be used
to query and modify the <B>treeview</B> widget. For example, to change the
background
color of the table to "green", you use the new command and the widget's
<B>configure</B> operation.
<PRE># Change the background color.
.h configure -background "green"</PRE>
By default, the <B>treeview</B> widget will automatically create a new tree object
to contain the data. The name of the new tree is the pathname of the
widget. Above, the new tree object name is ".h". But you can use the
<B>-tree</B> option to specify the name of another tree.
<PRE># View the tree "myTree".
.h configure -tree "myTree"</PRE>
When a new tree is created, it contains only a root node. The node
is automatically opened. The id of the root node is always
<B>0</B> (you can use also use the special id <B>root</B>). The
<B>insert</B> operation lets you insert one or more new entries into
the tree. The last argument is the node's <I>pathname</I>.
<PRE># Create a new entry named "myEntry"
set id [ .h insert end "myEntry"]</PRE>
This appends a new node named "myEntry". It will positioned as the
last child of the root of the tree (using the position "end"). You
can supply another position to order the node within its siblings.
<PRE># Prepend "fred".
set id [ .h insert 0 "fred"]</PRE>
Entry names do not need to be unique. By default, the node's label
is its name. To supply a different text label, add the <B>-label</B>
option.
<PRE># Create a new node named "fred"
set id [ .h insert end "fred" -label "Fred Flintstone"]</PRE>
The <B>insert</B> operation returns the id of the new node. You can
also use the <B>index</B> operation to get this information.
<PRE># Get the id of "fred"
.h index "fred"</PRE>
To insert a node somewhere other than root, use the <B>-at</B> switch.
It takes the id of the node where the new child will be added.
<PRE># Create a new node "barney" in "fred".
.h insert -at $id end "barney"</PRE>
A pathname describes the path to an entry in the hierarchy. It's a
list of entry names that compose the path in the tree. Therefore, you
can also add "barney" to "fred" as follows.
<PRE># Create a new sub-entry of "fred"
.h insert end "fred barney"</PRE>
Every name in the list is ancestor of the next. All ancestors must
already exist. That means that an entry "fred" is an ancestor of
"barney" and must already exist. But you can use the
<B>-autocreate</B> configuration option to force the creation of
ancestor nodes.
<PRE># Force the creation of ancestors.
.h configure -autocreate yes
.h insert end "fred barney wilma betty"</PRE>
Sometimes the pathname is already separated by a character sequence
rather than formed as a list. A file name is a good example of this.
You can use the <B>-separator</B> option to specify a separator string
to split the path into its components. Each pathname inserted is
automatically split using the separator string as a separator.
Multiple separators are treated as one.
<PRE>.h configure -separator /
.h insert end "/usr/local/tcl/bin"</PRE>
If the path is prefixed by extraneous characters, you can
automatically trim it off using the <B>-trim</B> option. It removed
the string from the path before it is parsed.
<PRE>.h configure -trim C:/windows -separator /
.h insert end "C:/window/system"</PRE>
You can insert more than one entry at a time with the <B>insert</B>
operation. This can be much faster than looping over a list of names.
<PRE># The slow way
foreach f [glob $dir/*] {
.h insert end $f
}
# The fast way
eval .h insert end [glob $dir/*]</PRE>
In this case, the <B>insert</B> operation will return a list of ids
of the new entries.
<P>
You can delete entries with the <B>delete</B> operation. It takes one or
more tags of ids as its argument. It deletes the entry and all its
children.
<PRE>.h delete $id</PRE>
Entries have several configuration options. They control the appearance
of the entry's icon and label. We have already seen the <B>-label</B>
option that sets the entry's text label. The <B>entry configure</B>
operation lets you set or modify an entry's configuration options.
<PRE>.h entry configure $id -color red -font fixed</PRE>
You can hide an entry and its children using the <B>-hide</B> option.
<PRE>.h entry configure $id -hide yes</PRE>
More that one entry can be configured at once. All entries specified
are configured with the same options.
<PRE>.h entry configure $i1 $i2 $i3 $i4 -color brown</PRE>
An icon is displayed for each entry. It's a Tk image drawn to the
left of the label. You can set the icon with the entry's
<B>-icons</B> option. It takes a list of two image names: one to
represent the open entry, another when it is closed.
<PRE>set im1 [image create photo -file openfolder.gif]
set im2 [image create photo -file closefolder.gif]
.h entry configure $id -icons "$im1 $im2"</PRE>
If <B>-icons</B> is set to the empty string, no icons are display.
<P>
If an entry has children, a button is displayed to the left of the
icon. Clicking the mouse on this button opens or closes the
sub-hierarchy. The button is normally a <B>+</B> or <B>-</B>
symbol, but can be configured in a variety of ways using the <B>button
configure</B> operation. For example, the <B>+</B> and <B>-</B>
symbols can be replaced with Tk images.
<PRE>set im1 [image create photo -file closefolder.gif]
set im2 [image create photo -file downarrow.gif]
.h button configure $id -images "$im1 $im2" \
-openrelief raised -closerelief raised</PRE>
Entries can contain an arbitrary number of <I>data fields</I>. Data
fields are name-value pairs. Both the value and name are strings.
The entry's <B>-data</B> option lets you set data fields.
<PRE>.h entry configure $id -data {mode 0666 group users}</PRE>
The <B>-data</B> takes a list of name-value pairs.
<P>
You can display these data fields as <I>columns</I> in the
<B>treeview</B> widget. You can create and configure columns with
the <B>column</B> operation. For example, to add a new column to the
widget, use the <B>column insert</B> operation. The last argument is
the name of the data field that you want to display.
<PRE>.h column insert end "mode"</PRE>
The column title is displayed at the top of the column. By default,
it's is the field name. You can override this using the column's
<B>-title</B> option.
<PRE>.h column insert end "mode" -title "File Permissions"</PRE>
Columns have several configuration options. The <B>column
configure</B> operation lets you query or modify column options.
<PRE>.h column configure "mode" -justify left</PRE>
The <B>-justify</B> option says how the data is justified within in
the column. The <B>-hide</B> option indicates whether the column is
displayed.
<PRE>.h column configure "mode" -hide yes</PRE>
Entries can be selected by clicking on the mouse. Selected entries
are drawn using the colors specified by the <B>-selectforeground</B>
and <B>-selectbackground</B> configuration options.
The selection itself is managed by the <B><A HREF="../TkCmd/selection.htm">selection</A></B> operation.
<PRE># Clear all selections
.h selection clear 0 end
# Select the root node
.h selection set 0</PRE>
The <B>curselection</B> operation returns a list of ids of
all the selected entries.
<PRE>set ids [ .h curselection]</PRE>
You can use the <B>get</B> operation to convert the ids to
their pathnames.
<PRE>set names [eval .h get -full $ids]</PRE>
If a treeview is exporting its selection (using the
<B>-exportselection</B> option), then it will observe the standard X11
protocols for handling the selection. Treeview selections are
available as type <B><A HREF="../TclCmd/string.htm">STRING</A></B>; the value of the selection will be the
pathnames of the selected entries, separated by newlines.
<P>
The <B>treeview</B> supports two modes of selection: <B>single</B>
and <B>multiple</B>. In single select mode, only one entry can be
selected at a time, while multiple select mode allows several entries
to be selected. The mode is set by the widget's <B>-selectmode</B>
option.
<PRE>.h configure -selectmode "multiple"</PRE>
You can be notified when the list of selected entries changes. The widget's
<B>-selectcommand</B> specifies a Tcl procedure that is called whenever
the selection changes.
<PRE>proc SelectNotify { widget } {
set ids [ $widget curselection]
}
.h configure -selectcommand "SelectNotify .h"</PRE>
The widget supports the standard Tk scrolling and scanning operations.
The <B>treeview</B> can be both horizontally and vertically. You can
attach scrollbars to the <B>treeview</B> the same way as the listbox
or canvas widgets.
<PRE>scrollbar .xbar -orient horizontal -command ".h xview"
scrollbar .ybar -orient vertical -command ".h yview"
.h configure -xscrollcommand ".xbar set" \
-yscrollcommand ".ybar set"</PRE>
Entries can be programmatically opened or closed using the <B><A HREF="../TclCmd/open.htm">open</A></B>
and <B><A HREF="../TclCmd/close.htm">close</A></B> operations respectively.
<PRE>.h open $id
.h close $id</PRE>
When an entry is opened, a Tcl procedure can be automatically invoked.
The <B>-opencommand</B> option specifies this procedure. This
procedure can lazily insert entries as needed.
<PRE>proc AddEntries { dir } {
eval .h insert end [glob -nocomplain $dir/*]
}
.h configure -opencommand "AddEntries %P"</PRE>
Now when an entry is opened, the procedure <B>AddEntries</B> is
called and adds children to the entry. Before the command is invoked,
special "%" substitutions (like <B><A HREF="../TkCmd/bind.htm">bind</A></B>) are performed. Above,
<B>%P</B> is translated to the pathname of the entry.
<P>
The same feature exists when an entry is closed. The
<B>-closecommand</B> option specifies the procedure.
<PRE>proc DeleteEntries { id } {
.h entry delete $id 0 end
}
.h configure -closecommand "DeleteEntries %#"</PRE>
When an entry is closed, the procedure <B>DeleteEntries</B> is called
and deletes the entry's children using the <B>entry delete</B> operation
(<B>%#</B> is the id of entry).
