<h2>Item Tags</h2>
Tags are textual labels applied to items to group them together. Tags
do not affect the appearance or behaviour of items. Tags can be used in
item descriptions to operate on multiple items. More information can be
found in the <a href="treectrl.html#item_tags">man page</a>.<br>
<h2>Window Element</h2>
Window elements can now be properly clipped so they don't draw over the
column header, borders, or outside the bounds of the item
columns they occupy. This is accomplished by making the window you want
to display a child of a borderless frame widget, and setting the new <span style="font-weight: bold;">-clip</span> option of the
window element to TRUE. So if your program displays a canvas widget in
a window element, you would change this code:<br>
<pre style="margin-left: 40px;">set canvas [canvas .t.canvas ...]<br>.t item element configure $item $column myElement -window $canvas</pre>
to this:<br>
<pre style="margin-left: 40px;">set frame [frame .t.clip -borderwidth 0]<br>set canvas [canvas $frame.canvas ...]<br>.t item element configure $item $column myElement -window $frame -clip yes</pre>
The <span style="font-weight: bold;">-clip</span>
option tells the window element to manage the geometry of both the <span style="font-weight: bold;">-window</span>
widget (i.e,
the frame) and its first child widget (i.e., the canvas). In this case,
the frame widget is kept sized and positioned so that it is never
out-of-bounds. You can see this in the "Big List" and "Firefox Privacy"
demos.
<h2>Item Descriptions</h2>
New keywords were added to allow multiple items to be specified by an <a href="treectrl.html#item_description">item description</a>:<br>
<ul>
<li>The keyword <span style="font-weight: bold;">list</span>
specifies a list of other item descriptions:
<pre>.t item id "list [list $a $b $c]"</pre>
</li>
<li>The keyword <span style="font-weight: bold;">range</span>
operates like the <span style="font-weight: bold;">item
range</span> command:
<pre>.t item id "range $first $last"</pre>
</li>
<li>The keyword <span style="font-weight: bold;">tag</span>
matches any items that meet a tag expression:
<pre>.t item id "tag $tagExpr"</pre>
</li>
</ul>
New modifiers were added to match multiple items:
<ul>
<li>The modifier <span style="font-weight: bold;">ancestors</span>
operates like the <span style="font-weight: bold;">item
ancestors</span> command:
<pre>.t item id "$item ancestors"</pre>
</li>
<li>The modifier <span style="font-weight: bold;">children</span>
operates like the <span style="font-weight: bold;">item
children</span> command:
<pre>.t item id "$item children"</pre>
</li>
<li>The modifier <span style="font-weight: bold;">descendants</span>
operates like the <span style="font-weight: bold;">item
descendants</span> command:
<pre>.t item id "$item descendants"</pre>
</li>
</ul>
New qualifiers were added to refine which items are matched:<br>
<ul>
<li>The qualifier <span style="font-weight: bold;">!visible</span>
matches items that are not displayed:
<pre>.t item id "first !visible" ; # find the first item that is not displayed</pre>
</li>
<li>The qualifier <span style="font-weight: bold;">state</span>
matches items that have certain states set (or not set if '!' is used):
<pre>.t item id "first state {selected !open}" ; # find the first item that is selected and collapsed</pre>
</li>
<li>The qualifier <span style="font-weight: bold;">tag</span>
matches items that meet a tag expression:
<pre>.t item id "$item children tag $tagExpr" ; # find children of $item that have certain tags</pre>
</li>
</ul>
Also, the keyword <span style="font-weight: bold;">all</span>
may now be followed by a list of qualifiers: For example:<br>
<pre style="margin-left: 40px;">.t item id "all !visible state myState" ; # find every item that is not displayed with user-defined state "myState"</pre>
The following commands can now operate on multiple items in a single
call:<br>
<ul>
<li>item configure</li>
<li> item element configure</li>
<li>item id</li>
<li> item image</li>
<li> item style map</li>
<li> item style set</li>
<li> item state forcolumn</li>
<li> item state set</li>
<li> item remove</li>
<li> item span</li>
<li> item text</li>
</ul>
<h2>Demo Changes</h2>
<ul>
<li>New demo "My Computer". Demonstrates disabled items used as
headers.</li>
</ul>
<h2>Bug Fixes</h2>
<ul>
<li><span style="font-weight: bold;">item create</span>:
Fixed bug where <span style="font-weight: bold;">-nextsibling</span>
and <span style="font-weight: bold;">-prevsibling</span>
options could specify an orphan item.</li>
<li><span style="font-weight: bold;">item delete</span>:
Stopped items possibly being double-deleted by nested calls through <span style="font-weight: bold;"><Selection></span>
and <span style="font-weight: bold;"><ItemDelete></span>
binding scripts.</li>
<li><span style="font-weight: bold;">item expand</span>, <span style="font-weight: bold;">item collapse</span>, <span style="font-weight: bold;">item toggle</span>: Only
operate on items which exist when the command is called, not any that
might get created by <span style="font-weight: bold;"><Expand></span>
or <span style="font-weight: bold;"><Collapse></span>
binding scripts.</li>
<li>When a style with window elements spanned more than one
column, the window might be improperly sized during display updates.</li>
</ul>

<h1>What's New in TkTreeCtrl 2.1.1</h1>
<h2>Column Command</h2>
<table style="text-align: left; width: 100%;" border="1" cellpadding="2" cellspacing="2">
<tbody>
<tr>
<th style="background-color: rgb(255, 255, 204); width: 50%;">Arguments/Result
Changed</th>
<th style="background-color: rgb(204, 255, 255);">What
changed</th>
</tr>
<tr>
<td>column delete<br>
</td>
<td>Added an optional second argument allowing a range of
columns to be deleted.</td>
</tr>
</tbody>
</table>
<h2>Bug Fixes</h2>
<ul>
<li>The <span style="font-weight: bold;">item sort</span>
command
will be much faster in many cases. There was a silly error in the
pivot-finding code of quicksort which resulted in the slow-down.</li>
<li>A column header will be redisplayed if an image in
the header is altered.</li>
<li>Fixed bus errors on some Unix systems due to alignment
problems.</li>
</ul>
<h2>Other Changes</h2>
<ul>
<li>The Tk caret is now positioned over the active item when it
changes. The Tk caret is used for the Magnifier accessibility
application and IME on Windows, as well as XIM under Unix.</li>
<li>Improved the appearance of the column headers under OSX.</li>
<li>Added <MouseWheel> support to OSX.</li>
<li>Changing the -visible option of an item could be slow if
any
items were selected. That is because non-visible items may not be part
of the selection. A change was made so that changes to the selection
caused by modifying the -visible option of an item do not occur until
the next display update.</li>
</ul>
<h2>Demo Changes</h2>
<ul>
<li>New demo "Column Spanning". Demonstrates a 100-column list
where styles span from 1 to 20 columns each.</li>
<li>The <span style="font-weight: bold;">loupe</span>
command (which performs screen capture to an image) is now implemented
on Windows and OSX thanks to Jeff Hobbs.</li>
<li>The screen-magnifier image now resizes with the "loupe"
window.</li>
</ul>

<h2>Style Layout Changes</h2>
<ul>
<li>Column justification will now affect the position of
elements in 2 situations which previously had no effect (<span style="color: rgb(255, 0, 0);">Potential incompatibility</span>):</li>
</ul>
<ol style="margin-left: 40px;">
<li>If a -detach element had a fixed width larger than the
other elements.</li>
<li>If an element had -iexpand x specified as well as
-maxwidth, leaving some space available.</li>
</ol>
<h2>Element Changes</h2>
<ul>
<li>Bitmap, image and text elements are drawn clipped if given
less space than they need.</li>
<li>Fixed line wrapping of text elements. It did not work for
single lines of text at all (<span style="color: rgb(255, 0, 0);">Potential
incompatibility</span>).</li>
<li>The text -wrap option can now be <span style="font-weight: bold;">none</span> to disable line
wrapping.</li>
</ul>
<h2>Event Changes</h2>
<ul>
<li>The new static event <span style="font-weight: bold;"><ItemVisibility></span>
is generated when items become visible on screen and when items are no
longer visible on screen.
This event allows you to create really big lists by only assigning
styles when items are about to be displayed. See the EVENTS AND SCRIPT
SUBSTITUTIONS section in the help
file, and the new demo "Big List".</li>
</ul>
<h2>Other Changes</h2>
<ul>
<li>On WinXP, the column header sort arrow is drawn like
Explorer draws it if <span style="font-weight: bold;">-usetheme</span>
is true.</li>
</ul>
<h2>Demo Changes</h2>
<ul>
<li>New demo "Big List". Demonstrates the new <span style="font-weight: bold;"><ItemVisibility></span>
event, using <Expand-before> to add items on demand, and
column spanning.</li>
<li>The context menu has a <span style="font-weight: bold;">Span</span>
submenu that lets you manipulate column spanning in items. See
the <span style="font-weight: bold;">item span</span>
command in the help file.</li>
<li>Under WinXP, the "Explorer" demos will use the new <span style="font-weight: bold;">shellicon</span>
extension if available. This extension allows a treectrl to display
file/folder icons using the Win32 Shell API. It may work on other
versions of Windows but it hasn't been tested.</li>

<li>On OSX/Aqua, the column headers and open/close
buttons are
drawn
using the system theme if <span style="font-weight: bold;">-usetheme</span>
is true. The sort arrow will be drawn by the Appearance Manager as
well. This will override the <span style="font-weight: bold;">-arrowside</span>
and <span style="font-weight: bold;">-arrowgravity</span>
options.</li>
<li>Columns can be moved by drag-and-drop. See <span style="font-weight: bold;">column dragconfigure</span>

in the help
file and the new demo "Firefox Privacy".</li>
<li>The new item description <span style="font-weight: bold;">end</span>
is equivalent to <span style="font-weight: bold;">last</span>.</li>
<li><span style="color: rgb(255, 0, 0);">If you
have version 1.1
installed, replace the old pkgIndex.tcl file with the one from this
version (but replace the version number 2.0 with 1.1).<span style="color: rgb(0, 0, 0);"> Otherwise the old pkgIndex.tcl
file will
set the TREECTRL_LIBRARY variable which will override where the library
scripts are found.</span></span></li>
</ul>
