+<dl> 
+<dt><b class='cmd'>treectrl</b> <i class='arg'>pathName</i> ?<i class='arg'>options</i>?<dd>
+
+</dl>
+
+<p>
+The <b class='cmd'>treectrl</b> command creates a new window (given by the
+<i class='arg'>pathName</i> argument) and makes it into a treectrl widget.
+Additional options, described above, may be specified on the
+command line or in the option database
+to configure aspects of the treectrl such as its background color
+and relief.  The <b class='cmd'>treectrl</b> command returns the
+path name of the new window.
+At the time this command is invoked, there must not
+exist a window named <i class='arg'>pathName</i>, but <i class='arg'>pathName</i>'s parent must exist.
+
+<p>
+A treectrl is a widget which displays items one per line.
+Every item has a set of states, which are boolean properties.
+The item may be spread about one or more columns.
+For each column of an item there is a style associated,
+which determines how to display the item's column
+respecting the item's current state set.
+One column can be defined to display the data in a hierarchical structure.
+
+<p>
+Normally the origin of the coordinate system is at the
+upper-left corner of the window containing the treectrl.
+It is possible to adjust the origin of the coordinate system
+relative to the origin of the window using the
+<b class='cmd'>xview</b> and <b class='cmd'>yview</b> widget commands;
+this is typically used for scrolling.
+
+<p>
+A treectrl widget can be horizontal or vertical oriented
+like many other Tk widgets.
+For displaying hierarchical data only vertical orientation is useful,
+since only then the children of an item
+are displayed directly below their parent.
+If the treectrl widget is used only
+to display data in a multicolumn listbox,
+the specification of an orientation will give useful results.

+
+<a name="widgetcommand"><h2>WIDGET COMMAND</h2>
+The <b class='cmd'>treectrl</b> command creates a new Tcl command whose
+name is the same as the path name of the treectrl's window.
+This command may be used to invoke various
+operations on the widget.  It has the following general form:
+
+<p>
+<i class='arg'>pathName</i> <i class='arg'>option</i> ?<i class='arg'>arg arg ...</i>?
+
+<p>
+<i class='arg'>PathName</i> is the name of the command, which is the same as
+the treectrl widget's path name.  <i class='arg'>Option</i> and the <i class='arg'>arg</i>s
+determine the exact behavior of the command.  The following
+commands are possible for treectrl widgets:
+
+<dl>
+
+<dt><i class='arg'>pathName</i> <b class='cmd'>activate</b> <i class='arg'>itemDesc</i><dd>
+
+Sets the active item to the one described by <i class='arg'>itemDesc</i>,
+and switches on the state <strong>active</strong> for this item.
+From now on the item can be retrieved with the item description <strong>active</strong>.
+An <strong>&lt;ActiveItem&gt;</strong> event is generated.
+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>canvasx</b> <i class='arg'>screenx</i><dd>
+
+Given a window x-coordinate in the treectrl <i class='arg'>screenx</i>,
+this command returns the treectrl x-coordinate
+that is displayed at that location.
+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>canvasy</b> <i class='arg'>screeny</i><dd>
+
+Given a window y-coordinate in the treectrl <i class='arg'>screeny</i>,
+this command returns the treectrl y-coordinate
+that is displayed at that location.
+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>cget</b> <i class='arg'>option</i><dd>
+
+Returns the current value of the configuration option given
+by <i class='arg'>option</i>.
+<i class='arg'>Option</i> may have any of the values accepted by the <b class='cmd'>tree</b>
+command.
+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>collapse</b> ?<strong>-recurse</strong>? ?<i class='arg'>itemDesc</i> <i class='arg'>...</i>?<dd>
+
+Switches off the <strong>open</strong> state of the item(s) described by <i class='arg'>itemDesc</i>.
+If the item has descendants, they are no longer displayed.
+If the item is configured to have a button,
+the button will now display the image or bitmap configured with the
+widget options <strong>-closedbuttonimage</strong> or <strong>-closedbuttonbitmap</strong>,
+or a <strong>+</strong> sign if no image or bitmap is configured.
+If the item is already closed, this command has no effect.
+<i class='arg'>ItemDesc</i> may also be the string <strong>all</strong>,
+in which case all items of the treectrl widget are collapsed.
+If <strong>-recurse</strong> is specified, all descendants of <i class='arg'>itemDesc</i>
+will also be collapsed.
+For every item, that actually will be collapsed,
+two events are generated:
+a <strong>&lt;Collapse-before&gt;</strong> event before the item state is changed,
+and a <strong>&lt;Collapse-after&gt;</strong> event after the item state was changed.
+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>column</b> <i class='arg'>option</i> <i class='arg'>column</i> ?<i class='arg'>arg</i> <i class='arg'>...</i>?<dd>
+
+This command is used to manipulate the columns of the treectrl widget
+(see section <a href="#columns">COLUMNS</a> below).
+The exact behavior of the command depends on the <i class='arg'>option</i> argument
+that follows the <b class='cmd'>column</b> argument.
+The following forms of the command are supported:
+
+<br><br>
+<dl>
+<dt><i class='arg'>pathName</i> <b class='cmd'>column bbox</b> <i class='arg'>column</i><dd>
+
+Returns a list with four elements giving an approximate bounding box
+for the column header specified by <i class='arg'>column</i>.
+If the treectrl is configured to don't display the column headers
+by means of the <strong>-showheader</strong> option,
+an empty list is returned instead.
+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>column cget</b> <i class='arg'>column</i> <i class='arg'>option</i><dd>
+
+This command returns the current value of the option named <i class='arg'>option</i>
+for the column specified by <i class='arg'>column</i>,
+<i class='arg'>Column</i> may also be the string <strong>tail</strong> to specify the tail column.
+<i class='arg'>Option</i> may have any of the values accepted by the
+<b class='cmd'>column configure</b> widget command.
+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>column configure</b> <i class='arg'>column</i> ?<i class='arg'>option</i>? ?<i class='arg'>value</i>? ?<i class='arg'>option</i> <i class='arg'>value</i> <i class='arg'>...</i>?<dd>
+
+This command is similar to the <b class='cmd'>configure</b> widget command except
+that it modifies options associated with the column specified by <i class='arg'>column</i>
+instead of modifying options for the overall treectrl widget.
+<i class='arg'>Column</i> may also be the string <strong>tail</strong> to specify the tail column.
+If no <i class='arg'>option</i> is specified, the command returns a list describing
+all of the available options for <i class='arg'>column</i> (see <strong>Tk_ConfigureInfo</strong>
+for information on the format of this list).
+If <i class='arg'>option</i> is specified with no <i class='arg'>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 class='arg'>option</i>
+is specified).
+If one or more <i class='arg'>option</i>-<i class='arg'>value</i> pairs are specified, then the command
+modifies the given option(s) to have the given value(s) for <i class='arg'>column</i>;
+in this case the command returns an empty string.<br><br>
+
+The specified column is created, if it not already exists
+and if at least one <i class='arg'>option</i>-<i class='arg'>value</i> pair is specified.
+See <a href="#columns">COLUMNS</a> below for details on the options available for columns.
+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>column delete</b> <i class='arg'>column</i><dd>
+
+Deletes the specified <i class='arg'>column</i> from the treectrl widget.
+All remaining columns of the treectrl widget will get new column numbers:
+in an unchanged order, but with succesive numbers.
+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>column index</b> <i class='arg'>column</i><dd>
+
+This command returns a decimal string giving the column number
+of the column specified by <i class='arg'>column</i>,
+which may also be the string <strong>tail</strong> to specify the tail column.
+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>column move</b> <i class='arg'>column</i> <i class='arg'>before</i><dd>
+
+Moves the specified <i class='arg'>column</i> to the left of the column
+specified by <i class='arg'>before</i>.
+If <i class='arg'>before</i> is the string <strong>tail</strong>,
+the column <i class='arg'>column</i> will become the last column.
+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>column neededwidth</b> <i class='arg'>column</i><dd>
+
+This command returns a decimal string giving the needed width
+of the column specified by <i class='arg'>column</i>.
+The needed width is the maximum of the width of the column header
+and the width of the <em>widest</em> currently visible item.
+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>column width</b> <i class='arg'>column</i><dd>
+
+This command returns a decimal string giving the width
+of the column specified by <i class='arg'>column</i>,
+even if the treectrl is configured to don't display the column headers
+by means of the <strong>-showheader</strong> option.
+</dl>
+
+<dt><i class='arg'>pathName</i> <b class='cmd'>compare</b> <i class='arg'>itemDesc1</i> <i class='arg'>op</i> <i class='arg'>itemDesc2</i><dd>
+
+From both items described by the <i class='arg'>itemDesc</i>s the index is retrieved
+(as returned from the <b class='cmd'>item index</b> widget command).
+Then these indexes are compared using the operator <i class='arg'>op</i>, which must
+be either <strong>&lt;</strong>,  <strong>&lt;=</strong>,  <strong>==</strong>, <strong>&gt;=</strong>, <strong>&gt;</strong>,
+or <strong>!=</strong>.
+The return value of this command is 1 if the comparison evaulated to true,
+0 otherwise.

+
+Query or modify the configuration options of the widget.
+If no <i class='arg'>option</i> is specified, returns a list describing all of
+the available options for <i class='arg'>pathName</i> (see <strong>Tk_ConfigureInfo</strong> for
+information on the format of this list).  If <i class='arg'>option</i> is specified
+with no <i class='arg'>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 class='arg'>option</i> is specified).  If
+one or more <i class='arg'>option</i>-<i class='arg'>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 class='arg'>Option</i> may have any of the values accepted by the <b class='cmd'>treectrl</b>
+command.
+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>contentbox</b><dd>
+
+Returns a list with four elements giving an approximate bounding box
+for the space used to display the items inside the columns,
+i.e. the space of the treectrl widget without
+the surrounding borders and the column headers.
+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>debug</b> <i class='arg'>option</i> ?<i class='arg'>arg</i> <i class='arg'>arg</i> <i class='arg'>...</i>?<dd>
+
+This command is used to facilitate debugging of the treectrl widget.
+The exact behavior of the command depends on the <i class='arg'>option</i> argument
+that follows the <b class='cmd'>debug</b> argument.
+The following forms of the command are supported:
+
+<br><br>
+<dl>
+<dt><i class='arg'>pathName</i> <b class='cmd'>debug cget</b> <i class='arg'>element</i> <i class='arg'>option</i><dd>
+
+This command returns the current value of the debugging option

+
+This command is similar to the <b class='cmd'>configure</b> widget command except
+that it modifies debugging options
+instead of modifying options for the overall treectrl widget.
+If no <i class='arg'>option</i> is specified, the command returns a list describing
+all of the available debugging options (see <strong>Tk_ConfigureInfo</strong>
+for information on the format of this list).

+<dt><i class='arg'>pathName</i> <b class='cmd'>dragimage</b> <i class='arg'>option</i> ?<i class='arg'>arg</i> <i class='arg'>...</i>?<dd>
+
+This command is used to manipulate the dragimage,
+one or more dotted lines around rectangular regions of the treectrl widget.
+The exact behavior of the command depends on the <i class='arg'>option</i> argument
+that follows the <b class='cmd'>dragimage</b> argument.
+The following forms of the command are supported:

+equal to, or greater than zero if the first element is to
+be considered less than, equal to, or greater than the second,
+respectively.
+
+<br><br>
+<dt><strong><strong>-dictionary</strong></strong><dd>
+Use dictionary-style comparison.  This is the same as <strong>-ascii</strong>
+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, in <strong>-dictionary</strong> mode, <strong>bigBoy</strong>
+sorts between <strong>bigbang</strong> and <strong>bigboy</strong>, and <strong>x10y</strong>
+sorts between <strong>x9y</strong> and <strong>x11y</strong>.
+
+<br><br>
+<dt><strong><strong>-integer</strong></strong><dd>
+Convert to integers and use integer comparison.
+
+<br><br>
+<dt><strong><strong>-notreally</strong></strong><dd>
+Does no real comparison; instead just turn the items upside-down.
+
+<br><br>
+<dt><strong><strong>-real</strong></strong><dd>
+Convert to floating-point values and use floating comparison.

+The exact behavior of the command depends on the <i class='arg'>command</i> argument
+that follows the <b class='cmd'>style</b> argument.
+The following forms of the command are supported:
+
+<br><br>
+<dl>
+<dt><i class='arg'>pathName</i> <b class='cmd'>item style elements</b> <i class='arg'>itemDesc</i> <i class='arg'>column</i><dd>

+
+<dt><i class='arg'>pathName</i> <b class='cmd'>marquee</b> <i class='arg'>option</i> ?<i class='arg'>arg</i> <i class='arg'>...</i>?<dd>
+
+This command is used to manipulate the marquee,
+a rectangular region of the treectrl widget
+optionally marked with a surrounding dotted line.
+One corner point of the marquee is fixed as long as the marquee is visible
+and called the anchor; the diagonally opposite corner is dragged with the
+mouse while resizing the marquee and simply called the corner.
+All coordinates handled by this widget command are treectrl coordinates,
+i.e. the <b class='cmd'>canvasx</b> or <b class='cmd'>canvasy</b> widget command should be
+used before any window coordinates can be used.
+The exact behavior of the command depends on the <i class='arg'>option</i> argument
+that follows the <b class='cmd'>marquee</b> argument.
+The following forms of the command are supported:
+
+<br><br>
+<dl>
+<dt><i class='arg'>pathName</i> <b class='cmd'>marquee anchor</b> ?<i class='arg'>x</i> <i class='arg'>y</i>?<dd>
+
+Returns a list containing the x and y coordinates of the anchor,

+
+This command is similar to the <b class='cmd'>configure</b> widget command except
+that it modifies the marquee options
+instead of modifying options for the overall treectrl widget.
+If no <i class='arg'>option</i> is specified, the command returns a list describing
+all of the available marquee options (see <strong>Tk_ConfigureInfo</strong>
+for information on the format of this list).
+If <i class='arg'>option</i> is specified with no <i class='arg'>value</i>, then the command returns
+a list describing the one named marquee option (this list will be identical to
+the corresponding sublist of the value returned if no <i class='arg'>option</i>
+is specified).
+If one or more <i class='arg'>option</i>-<i class='arg'>value</i> pairs are specified, then the command
+modifies the given marquee option(s) to have the given value(s);
+in this case the command returns an empty string.<br><br>
+
+The following marquee options are supported:
+
+<br><br>
+<dl>
+<dt><strong><strong>-visible</strong></strong> <i class='arg'>boolean</i><dd>
+Specifies a boolean value which determines
+whether the dotted line surrounding the region of the marquee
+should currently be visible.
+This option should not be modified by means of the
+<b class='cmd'>marquee configure</b> widget command;
+instead use the <b class='cmd'>marquee visible</b> widget command.

+<dt><i class='arg'>pathName</i> <b class='cmd'>marquee coords</b> ?<i class='arg'>x1</i> <i class='arg'>y1</i> <i class='arg'>x2</i> <i class='arg'>y2</i>?<dd>
+
+Returns a list containing the x and y coordinates of the anchor
+followed by the x and y coordinates of the corner,
+if no additional arguments are specified.
+If four coordinates are specified,
+sets the anchor to the given coordinates <i class='arg'>x1</i> and <i class='arg'>y1</i>
+and the corner to the coordinates <i class='arg'>x2</i> and <i class='arg'>y2</i>.
+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>marquee corner</b> ?<i class='arg'>x</i> <i class='arg'>y</i>?<dd>

+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>marquee identify</b><dd>
+
+Returns a list with information about the items inside the marquee.
+The list has as elements a list itself
+for every item which is displayed inside the marquee.
+The first element of these lists is the numerical item id,
+followed by another list with information about every column of the
+item inside the marque.
+These lists start with the column number,
+followed by the elements of the style defined for the item in this column
+if there are any.
+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>marquee visible</b> ?<i class='arg'>boolean</i>?<dd>
+
+If the additional argument specifies true, the dotted line will become
+visible and the marquee option <strong>-visible</strong> becomes 1;
+if it specifies false, the dotted line will be hidden
+and the marquee option <strong>-visible</strong> becomes 0.
+Returns 1 if the dotted line surrounding the marquee is currently visible,
+0 otherwise.

+
+<dt><i class='arg'>pathName</i> <b class='cmd'>notify</b> <i class='arg'>option</i> ?<i class='arg'>arg</i> <i class='arg'>...</i>?<dd>
+
+This command is used to manipulate the event mechanism of a treectrl widget,
+which stands in parallel to Tk's event mechanism.
+It has two major advantages:
+arbitrary new events can be defined
+together with arbitrary details,
+and before the event is triggered
+the called Tcl command underlys a customizable percent substitution.<br><br>
+
+The exact behavior of the command depends on the <i class='arg'>option</i> argument
+that follows the <b class='cmd'>notify</b> argument.
+The following forms of the command are supported:
+
+<br><br>
+<dl>
+<dt><i class='arg'>pathName</i> <b class='cmd'>notify bind</b> ?<i class='arg'>object</i>? ?<i class='arg'>pattern</i>? ?<i class='arg'>script</i>?<dd>
+
+This command associates <i class='arg'>script</i> with the object given by
+<i class='arg'>object</i> such that whenever the event sequence given by
+<i class='arg'>pattern</i> occurs for the object
+the command will be invoked.
+This widget command is similar to the <b class='cmd'>bind</b> command except that
+it operates on any object in a treectl rather than entire widgets,
+and it works also for non X11 event pattern.
+If all arguments are specified then a new binding is created, replacing
+any existing binding for the same <i class='arg'>pattern</i> and <i class='arg'>object</i>
+(if the first character of <i class='arg'>script</i> is ``+'' then <i class='arg'>script</i>
+augments an existing binding rather than replacing it).
+In this case the return value is an empty string.
+If <i class='arg'>script</i> is omitted then the command returns the <i class='arg'>script</i>
+associated with <i class='arg'>object</i> and <i class='arg'>pattern</i> (an error occurs
+if there is no such binding).
+If both <i class='arg'>script</i> and <i class='arg'>pattern</i> are omitted then the command
+returns a list of all the sequences for which bindings have been
+defined for <i class='arg'>object</i>.
+If no optional argument is specified, a list of all <i class='arg'>object</i>s
+to which a pattern-script combination is bound yet, is returned.
+
+<br><br>

+
+This command is similar to the <b class='cmd'>configure</b> widget command except
+that it modifies event options defined for <i class='arg'>pattern</i> in <i class='arg'>window</i>
+instead of modifying options for the overall treectrl widget.
+If no <i class='arg'>option</i> is specified, the command returns a list with
+<i class='arg'>option</i>-<i class='arg'>value</i> pairs describing all
+the available event options for <i class='arg'>pattern</i> in <i class='arg'>window</i>.
+If <i class='arg'>option</i> is specified with no <i class='arg'>value</i>,
+then the command does nothing.
+If one or more <i class='arg'>option</i>-<i class='arg'>value</i> pairs are specified, then the command
+modifies the given option(s) to have the given value(s) for the layout;
+in this case the command returns an empty string.<br><br>
+
+The following event options are supported:
+<br><br>
+<dl>
+<dt><strong><strong>-active</strong></strong> <i class='arg'>boolean</i><dd>
+Specifies if the event should be active.
+As long as this option is specified as false,
+the event will not trigger.
+</dl>
+
+<dt><i class='arg'>pathName</i> <b class='cmd'>notify detailnames</b> <i class='arg'>eventName</i><dd>
+
+Returns a list containing the names of all details,
+which are installed for the event with the name <i class='arg'>eventName</i>
+by means of the <b class='cmd'>notify install detail</b> widget command
+or by the treectrl widget itself.
+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>notify eventnames</b><dd>
+
+Returns a list containing the names of all events,

+or by the treectrl widget itself.
+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>notify generate</b> <i class='arg'>pattern</i> ?<i class='arg'>charMap</i>?<dd>
+
+The event with the pattern <i class='arg'>pattern</i> is generated,
+if it is configured as active.
+If there are details defined for the event,
+<i class='arg'>pattern</i> must describe an <i class='arg'>eventName</i>-<i class='arg'>detail</i> pair,
+otherwise pattern should be a simple event name.<br><br>
+
+The optional <i class='arg'>charMap</i> is a list of <i class='arg'>key</i>-<i class='arg'>value</i> pairs
+as in the form returned by <b class='cmd'>array get</b>;
+each key has to be exactly one character.
+If this argument is specified,
+the following substitution will be done in the script
+registered for the generated event
+before it will be evaluated:
+every occurence of a percent character (<strong>%</strong>) followed by a <i class='arg'>key</i>
+will be replaced with its corresponding <i class='arg'>value</i>.

+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>notify install detail</b> <i class='arg'>eventName</i> <i class='arg'>detail</i> ?<i class='arg'>percentsCommand</i>?<dd>
+
+Installs a new detail <i class='arg'>detail</i> 
+for the event with the name <i class='arg'>eventName</i>.
+A detail create by this command is called dynamic,
+whereas details created by the treectrl widget itself are called static.<br><br>
+
+The optional <i class='arg'>percentsCommand</i> will be called
+before the event is triggered
+for every two character sequence
+starting with a percent character (<strong>%</strong>).
+The script is called with at least four additional arguments:
+the second character of the sequence,
+the window for which the event is triggered,
+<i class='arg'>eventName</i> and <i class='arg'>detail</i>,
+and finally the <i class='arg'>field</i>-<i class='arg'>value</i> pairs specified
+as arguments in the <b class='cmd'>notify generate</b> call to generate the event
+(the leading dash is dropped from the <i class='arg'>field</i>s).
+The two character sequence of the command will be replaced by
+the returning string, or by an empty string
+if the command returns with a returnCode other than 0.
+
+<br><br>

+
+Installs a new event with the name <i class='arg'>eventName</i>.
+An event create by this command is called dynamic,
+whereas events created by the treectrl widget itself are called static.
+For the optional <i class='arg'>percentsCommand</i> argument
+see the description of the <b class='cmd'>notify install detail</b> widget command above;
+the value for the argument <i class='arg'>detail</i> is the empty string.

+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>notify uninstall detail</b> <i class='arg'>eventName</i> <i class='arg'>detail</i><dd>
+
+If the specified detail <i class='arg'>detail</i> 
+of the event with the name <i class='arg'>eventName</i> is static
+(i.e. created by the treectrl widget itself), an error is generated.
+Otherwise the dynamic detail is removed from the event.
+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>notify uninstall event</b> <i class='arg'>eventName</i><dd>
+
+If the specified event with the name <i class='arg'>eventName</i> is static

+Otherwise the dynamic event is removed.
+</dl>
+
+<dt><i class='arg'>pathName</i> <b class='cmd'>numcolumns</b><dd>
+
+Returns a decimal string giving the number of
+columns configured in the treectrl widget.
+Since the always existant tail column is ignored by this command,

+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>numitems</b><dd>
+
+Returns a decimal string giving the number of
+items created in the treectrl widget.
+This number is always positive,

+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>state</b> <i class='arg'>option</i> ?<i class='arg'>stateName</i>?<dd>
+
+This command is used to manipulate the list of user defined states,
+see section <a href="#states">STATES</a> below.
+The exact behavior of the command depends on the <i class='arg'>option</i> argument
+that follows the <b class='cmd'>state</b> argument.
+The following forms of the command are supported:
+
+<br><br>
+<dl>
+<dt><i class='arg'>pathName</i> <b class='cmd'>state define</b> <i class='arg'>stateName</i><dd>

+
+This command is used to manipulate styles, which could be considered
+as a geometry manager for the elements of one item.
+The exact behavior of the command depends on the <i class='arg'>option</i> argument
+that follows the <b class='cmd'>style</b> argument.
+The following forms of the command are supported:

+If one or more <i class='arg'>option</i>-<i class='arg'>value</i> pairs are specified, then the command
+modifies the given option(s) to have the given value(s) in <i class='arg'>style</i>;
+in this case the command returns an empty string.<br><br>
+
+The options of a style have effect on all elements managed by the style.
+The following options are supported:
+
+<br><br>
+<dl>
+<dt><strong><strong>-orient</strong></strong> <i class='arg'>varName</i><dd>
+This option specifies which orientation should be used
+when laying out the elements associated with this style.
+Must be either <strong>horizontal</strong> (the default)
+or <strong>vertical</strong> or an abbreviation of one of these.
+</dl>
+
+<dt><i class='arg'>pathName</i> <b class='cmd'>style create</b> <i class='arg'>style</i> ?<i class='arg'>option</i> <i class='arg'>value</i> <i class='arg'>...</i>?<dd>
+
+Create a new style in <i class='arg'>pathName</i> with name <i class='arg'>style</i>.
+After <i class='arg'>style</i> there may be any number of <i class='arg'>option</i>-<i class='arg'>value</i>
+pairs, each of which sets one of the configuration options
+for the style.  These same <i class='arg'>option</i>-<i class='arg'>value</i> pairs may be
+used in <b class='cmd'>style configure</b> widget commands to change the styles's
+configuration.
+Returns the name of the new style.
+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>style delete</b> ?<i class='arg'>style</i> <i class='arg'>...</i>?<dd>
+
+Deletes each of the named styles and returns an empty string.
+If a style is deleted while it is still used to display
+one or more items,
+it is also removed from the style list of these items.
+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>style elements</b> <i class='arg'>style</i> ?<i class='arg'>elementList</i>?<dd>
+
+Specifies the elements which should be layed out by this style.
+Each element of <i class='arg'>elementList</i> must be the name of an element
+created by the widget command <b class='cmd'>element create</b>.
+Duplicate names in <i class='arg'>elementList</i> are ignored.
+An element which was specified in a former call of this command
+for <i class='arg'>style</i> but is not included in <i class='arg'>elementList</i>,
+will be deleted from the elements layed out by <i class='arg'>style</i>.<br><br>
+
+If the <i class='arg'>elementList</i> argument is not specified, a list is returned

+
+This command is similar to the <b class='cmd'>configure</b> widget command except
+that it modifies options used by <i class='arg'>style</i> for laying out <i class='arg'>element</i>
+instead of modifying options for the overall treectrl widget.
+If no <i class='arg'>option</i> is specified, the command returns a list with
+<i class='arg'>option</i>-<i class='arg'>value</i> pairs describing
+all of the available options for the layout.
+If <i class='arg'>option</i> is specified with no <i class='arg'>value</i>, then the command returns
+the value of the named option.
+If one or more <i class='arg'>option</i>-<i class='arg'>value</i> pairs are specified, then the command
+modifies the given option(s) to have the given value(s) for the layout;
+in this case the command returns an empty string.<br><br>
+
+The options of a layout have effect on exactly the one element <i class='arg'>element</i>

+
+<br><br>
+<dt><strong><strong>-expand</strong></strong> <i class='arg'>style</i><dd>
+<dt><strong><strong>-iexpand</strong></strong> <i class='arg'>style</i><dd>
+It can happen that the element's space is larger than its requested dimensions.
+These options may be used to position (or stretch) the slave within its cell.
+<i class='arg'>Style</i>  is a string that contains zero or more of the characters
+<strong>n</strong>, <strong>s</strong>, <strong>e</strong> or <strong>w</strong>.
+The string can contain other characters, but they are ignored.
+Each letter refers to a side (north, south,
+east, or west) in which direction the element will grow to.
+
+<br><br>
+<dt><strong><strong>-squeeze</strong></strong> <i class='arg'>style</i><dd>
+If an elements's area is smaller than its requested dimensions, this
+option may be used to allow shrinking of the element.
+<i class='arg'>Style</i>  is a string that contains zero or more of the characters
+<strong>x</strong> or <strong>y</strong>.
+The string can contain other characters, but they are ignored.

+
+Changes the <strong>open</strong> state of the item(s) described by <i class='arg'>itemDesc</i>.
+If the state is currently switched off,
+this command does the same as the <b class='cmd'>expand</b> widget command,
+otherwise the same as the <b class='cmd'>collapse</b> widget command.
+<i class='arg'>ItemDesc</i> may also be the string <strong>all</strong>,
+in which case the state of all items of the treectrl widget are toggled.
+If <strong>-recurse</strong> is specified, the state of all descendants of

+
+<br><br>
+<dt><i class='arg'>pathName</i> <b class='cmd'>xview</b> ?<i class='arg'>args</i>?<dd>
+
+This command is used to query and change the horizontal position of the

+It can take any of the following forms:
+
+<br><br>
+<dl>
+<dt><i class='arg'>pathName</i> <b class='cmd'>xview</b><dd>
+
+Returns a list containing two elements.
+Each element is a real fraction between 0 and 1;  together they describe

+For example, if the first element is .2 and the second element is .6,
+20% of the tree's area
+is off-screen to the left, the middle 40% is visible

+
+<a name="columns"><h2>COLUMNS</h2>
+A treectrl widget is capable of displaying multiple columns next to each
+other.
+An item can be considered as a row, which reaches over all columns.
+
+<p>
+Many of the widget commands for a treectrl take as one argument an
+indicator of which column of the treectrl to operate on.  These
+indicators are called <i class='arg'>column</i>s and may be specified
+as numerical index as given by the first <b class='cmd'>column configure</b>
+widget command which created the column or by its name,
+which can be configured my means of the <strong>-tag</strong> column option.
+
+<p>
+There is always one special column, the tail column, which fills
+all space to the right of the last ordinary column.
+This column has no number;
+it can only be specified by its tag <strong>tail</strong>, which cannot be modified.
+It is explicitely mentioned for a widget command,
+if its <i class='arg'>column</i> argument can also specify the tail column.
+
+<p>
+The following options are supported for columns:
+
+<dl>
+<dt><strong><strong>-arrow</strong></strong> <i class='arg'>direction</i><dd>
+Indicates whether or not an arrow should be drawn in the column header
+to the right of the column title.

+
+<br><br>
+<dt><strong><strong>-arrowpad</strong></strong> <i class='arg'>amount</i><dd>
+<i class='arg'>Amount</i> specifies how much padding to
+leave on the left and right side of the arrow.
+<i class='arg'>Amount</i> may be a list

+<dt><strong><strong>-borderwidth</strong></strong> <i class='arg'>size</i><dd>
+Specifies a non-negative value indicating the width
+of the 3-D border to draw around the outside of the column header
+ (if such a border is being drawn;  the <strong>-relief</strong> column option

+The value may have any of the forms acceptable to <strong>Tk_GetPixels</strong>.
+
+<br><br>
+<dt><strong><strong>-button</strong></strong> <i class='arg'>boolean</i><dd>
+Indicates whether or not a mouse click on the column header should

+<br><br>
+<dt><strong><strong>-font</strong></strong> <i class='arg'>fontName</i><dd>
+Specifies the font to use for the column title inside the column header.
+
+<br><br>

+that will be permitted for this column.
+
+<br><br>
+<dt><strong><strong>-relief</strong></strong> <i class='arg'>relief</i><dd>
+Specifies the 3-D effect desired for the column header containing the title.
+Acceptable values are the typical relief values,

+
+<br><br>
+<dt><strong><strong>-stepwidth</strong></strong> <i class='arg'>size</i><dd>
+Specifies a sort of tabbed alignment for columns that displays
+more than one item next to each other
+(typically in a treectrl widget with horizontal orientation).

+(typically in a treectrl widget with horizontal orientation).
+</dl>
+
+<a name="states"><h2>STATES</h2>
+A state consists basically of just a string: its <i class='arg'>stateName</i>.
+For every item a set of these states is managed,
+which means that every item can have every state switched on or off.
+The following states are predefined for every item:
+
+<dl>
+<dt><strong>active</strong><dd>
+At every time this state is set for exactly one item,
+which therefore is called the active item.
+When the treectrl widget is created or when the active item is deleted,
+the root item will become the active element.
+This state can be modified by means of the widget command <b class='cmd'>activate</b>.
+
+<br><br>
+<dt><strong>enabled</strong><dd>
+This state is set for every item, when it is created.
+It cannot be modified.
+
+<br><br>
+<dt><strong>focus</strong><dd>
+This state is set for every item,
+if the treectrl widget has currently the focus.
+It cannot be modified by means of a widget command,
+but is maintained as reaction of a &lt;FocusIn&gt; or &lt;FocusOut&gt; event.
+
+<br><br>
+<dt><strong>open</strong><dd>
+If this state is switched on,
+the descendants of the item are displayed
+- the item is expanded.
+If this state is switched off,
+the descendants of the item are not displayed
+- the item is collapsed.
+For a new item this state is switched on.
+It can be modified by means of the widget commands
+<b class='cmd'>expand</b>, <b class='cmd'>collapse</b>, or <b class='cmd'>toggle</b>.
+
+<br><br>
+<dt><strong>selected</strong><dd>
+This state is set for every item, which is included in the selection.
+It can be modified by means of the widget command <b class='cmd'>selection</b>.
+</dl>
+
+<p>
+By means of the <b class='cmd'>state define</b> widget command
+upto 27 additional <i class='arg'>stateName</i>s can be defined.
+
+<p>
+Some widget commands expect a <i class='arg'>stateDesc</i> argument,
+which is a <i class='arg'>stateName</i>
+optionally preceded by an exclamation mark (<strong>!</strong>).
+If the <i class='arg'>stateName</i> has no leading <strong>!</strong>
+it describes a currently switched on state,
+if it has a leading <strong>!</strong> it describes a currently switched off state.
+
+<p>
+Some widget commands expect a <i class='arg'>statePattern</i> argument,
+which should be a non empty list of <i class='arg'>stateDesc</i>s.
+The pattern matches, if for every element of the list
+the <i class='arg'>stateDesc</i> describes the same state as the item currently has.
+
+<a name="elements"><h2>ELEMENTS</h2>
+Elements are the smallest building block
+which are handled by a treectrl widget.
+One or more elements together can be combined to a style,
+which can be considered as a blueprint for an item.
+They can also be used to create an item directly
+by means of the <b class='cmd'>item complex</b> widget command.
+An element can be of type <strong>bitmap</strong>, <strong>border</strong>, <strong>image</strong>,
+<strong>rect</strong>, or <strong>text</strong>.
+For each element type there is a section below describing all options
+which can modify the behaviour of an element of this type.
+
+<p>
+There are some options which can be configured to get different values
+dependent on the state of the item in which their element is included.
+The values of these options are basically a list.
+If the list has one element, the value is valid regardless of the item state.
+A list with an even number of elements (<i class='arg'>value</i>-<i class='arg'>statePattern</i> pairs)
+specifies different values for different states.
+For acceptable values of <i class='arg'>statePattern</i>
+see the section <a href="#states">STATES</a> above.
+The last <i class='arg'>statePattern</i> can be empty,
+implementing a sort of <em>otherwise clause</em>.
+The options with this behaviour are called <em>per state options</em>.
+
+<a name="bitmapelement"><h2>BITMAP ELEMENT</h2>
+An element of type <strong>bitmap</strong> can be used to display a bitmap in an item.
+The following options are supported for bitmap elements:
+
+<dl>

+The following options are supported for border elements:
+
+<dl>
+<dt><strong><strong>-background</strong></strong> <i class='arg'>color</i><dd>
+Specifies as a per state option
+the color to use for the background of the border.
+
+<br><br>
+<dt><strong><strong>-filled</strong></strong> <i class='arg'>boolean</i><dd>
+Specifies whether the interior of the border should also be filled with

+
+<dl>
+<dt><strong><strong>-fill</strong></strong> <i class='arg'>fillColor</i><dd>
+Specifies as a per state option
+the color to be used to fill rectangle's area.

+
+<a name="eventsandscriptsubstitutions"><h2>EVENTS AND SCRIPT SUBSTITUTIONS</h2>
+Beside of all the normal Tk events, which are generated as reaction
+of e.g. mouse movements or key presses, 
+the treectrl widget generates at various places
+events created by treectrl widget:
+
+<dl>
+<dt><strong>&lt;ActiveItem&gt;</strong><dd>
+Generated without detail
+whenever the active item changes.
+
+<br><br>
+<dt><strong>&lt;Collapse&gt;</strong><dd>
+Generated with the detail <strong>after</strong> or <strong>before</strong>,
+whenever an item is collapsed.
+
+<br><br>
+<dt><strong>&lt;Expand&gt;</strong><dd>
+Generated with the detail <strong>after</strong> or <strong>before</strong>,
+whenever an item is expanded.
+
+<br><br>
+<dt><strong>&lt;Scroll&gt;</strong><dd>
+Generated with the detail <strong>x</strong> or <strong>y</strong>,
+whenever the origin of the window changes.
+
+<br><br>
+<dt><strong>&lt;Selection&gt;</strong><dd>
+Generated without detail
+whenever the selection changes.
+</dl>
+
+<p>
+By means of the <b class='cmd'>notify bind</b> widget command Tcl scripts can
+be specified,
+which will be executed whenever the event triggers.
+The command will be executed in the same interpreter that the
+<b class='cmd'>notify bind</b> command was executed in, and it will run at global
+level (only global variables will be accessible).
+If the script contains any <strong>%</strong> characters,
+then the script will not be executed directly.
+Instead, a new script will be
+generated by replacing each <strong>%</strong>,
+and the character following it,
+with information from the current event.
+The replacement depends on the character following the <strong>%</strong>,
+as defined in the list below.
+Unless otherwise indicated,
+Some of the substitutions are only valid for certain types of events;
+if they are used for other types of events
+the value substituted is undefined.
+
+<dl>
+<dt><strong>%%</strong><dd>
+Replaced with a single percent.
+<br><br>
+<dt><strong>%c</strong><dd>
+Replaced with the number of items that are currently selected
+for a selection event,
+or with the numerical id of the item, which will become the active item
+for an activation event,
+invalid for other event types.
+<br><br>
+<dt><strong>%d</strong><dd>
+Replaced with the detail of the event,
+or with the empty string if the event has no detail.
+Valid for all event types.
+<br><br>
+<dt><strong>%D</strong><dd>
+Replaced with a (possibly empty) list of item ids;
+all mentioned items will be removed from the selection.
+Valid only for selection events.
+<br><br>
+<dt><strong>%e</strong><dd>
+Replaced with the name of the event.
+Valid for all event types.
+<br><br>
+<dt><strong>%I</strong><dd>
+Replaced with the numerical id of the item,
+which is to be collapsed or expanded.
+Valid only for collapse or expand events.
+<br><br>
+<dt><strong>%l</strong><dd>
+Replaced with the lower bound, i.e. the first fraction
+as returned by the widget command <b class='cmd'>xview</b> for horizontal scrolling
+or <b class='cmd'>yview</b> for vertical scrolling.
+Valid only for scrolling events.
+<br><br>
+<dt><strong>%p</strong><dd>
+Replaced with the numerical id of the item,
+which was  the active item upto now.
+Valid only for activation events.
+<br><br>
+<dt><strong>%S</strong><dd>
+Replaced with a (possibly empty) list of item ids;
+all mentioned items will be added to the selection.
+Valid only for selection events.
+<br><br>
+<dt><strong>%T</strong><dd>
+Replaced with the path name of the treectrl widget.
+Valid for all event types.
+<br><br>
+<dt><strong>%u</strong><dd>
+Replaced with the upper bound, i.e. the second fraction
+returned by the widget command <b class='cmd'>xview</b> for horizontal scrolling
+or <b class='cmd'>yview</b> for vertical scrolling.
+Valid only for scrolling events.
+<br><br>
+<dt><strong>%W</strong><dd>
+Replaced with the name of the object the event is bound for.
+This can be a widget path (then the string starts with <strong>.</strong>),
+or a generic tag.
+Valid for all event types.
+</dl>
+
+<a name="defaultbindings"><h2>DEFAULT BINDINGS</h2>
+Tk automatically creates class bindings for treectrls that give them
+the following default behavior.
+<ol>
+<li>
+Clicking mouse button 1 over an item positions the active cursor
+on the item, sets the input focus to this widget,
+and resets the selection of the widget to this item, if it is not
+already in the selection.
+<br><br>
+<li>
+Clicking mouse button 1 with the Control key down will reposition the
+active cursor and add the item to the selection
+without ever removing any items from the selection.
+<br><br>
+<li>
+If the mouse is dragged out of the widget
+while button 1 is pressed, the treectrl will automatically scroll to
+make more items visible (if there are more items off-screen on the side
+where the mouse left the window).
+<br><br>
+<li>
+The Left and Right keys move the active cursor one item to the left or right;
+for an hierarchical tree with vertical orientation nothing will happen,
+since it has no two items in the same row.
+The selection is set to include only the active item.
+If Left or Right is typed with the Shift key down, then the active
+cursor moves and the selection is extended to include the new item.
+<br><br>
+<li>
+The Up and Down keys move the active cursor one item up or down.
+The selection is set to include only the active item.
+If Up or Down is typed with the Shift key down, then the active
+cursor moves and the selection is extended to include the new item.
+<br><br>
+<li>
+The Next and Prior keys move the active cursor forward or backwards
+by one screenful, without affecting the selection.
+<br><br>
+<li>
+Control-Next and Control-Prior scroll the view right or left by one page
+without moving the active cursor or affecting the selection.
+Control-Left and Control-Right behave the same.
+<br><br>
+<li>
+The Home and End keys scroll to the left or right end of the widget
+without moving the active cursor or affecting the selection.
+<br><br>
+<li>
+The Control-Home and Control-End keys scroll to the top or bottom
+of the widget, they also activate and select the first or last item.
+If also the Shift key is down, then the active
+cursor moves and the selection is extended to include the new item.
+<br><br>
+<li>
+The Space and Select keys set the selection to the active item.
+<br><br>
+<li>
+Control-/ selects the entire contents of the widget.
+<br><br>
+<li>
+Control-\\ clears any selection in the widget.
+<br><br>
+<li>
+The + and - keys expand or collapse the active item,
+the Return key toggles the active item.
+<br><br>
+<li>
+The mousewheel scrolls the view of the widget four lines up or down
+depending on the direction, the wheel was turned.
+The active cursor or the selection is not affected.
