New page

== Background ==

[http://tktreectrl.sourceforge.net/ TkTreeCtrl] is a pretty amazing set of interface functionality for displaying trees where each row can be a multi-column list and/or a set of interface widgets. The interface is highly configurable (as shown in the demos) and very efficient. It is a cross-platform tcl extension.

As of late June 2007, TkTreeCtrl is built as part of KWWidgets and is exposed for use in Slicer3. Note that it does not yet have a C++ API so any use of TkTreeCtrl must be implemented in tcl (this code can be invoked from C++ using the Script() method on a KWWidget).

== Running the Demo in Slicer3 ==

First, download and unpack the package from [http://tktreectrl.sourceforge.net/ TkTreeCtrl]. Version 2.2.3 or later should work.

In Slicer3:
* open the tcl console (Control-T or use the menu)
* cd to the directory where you unpacked TkTreeCtrl
* cd to the demos directory
* type the following commands
proc console {args} {}
source demo.tcl
wm deiconify .
* experiment and have fun!
** note that the File menu includes options for viewing the source of each demo (note how brief and elegant each demo is!)
** you can even watch the events as you interact with the tree demos
** you can edit the configuration parameters of the trees on the fly and see the visual result

== Plans ==

* Test the widget
** Example MRML tree (Steve) (see the ColorTree example described below)
** Model Hierarchy display properties (Alex)
** EMSegment (Brad)
** QueryAtlas (Wendy)
* Propose useful C++ API (all) for implementation by Sebastien and Yumin

* [http://tktreectrl.sourceforge.net/Understanding%20TkTreeCtrl.html a tutorial]
* [http://tktreectrl.sourceforge.net home page]

Note there is an HTML manpage with the source distribution that you can load into a browser to use as a reference.

== Example ==

The simple example below is taken from [http://wiki.tcl.tk/6064] and can be pasted directly into the slicer3 tcl console:

catch "destroy .t"
toplevel .t
package require treectrl
treectrl .t.t
pack .t.t
.t.t column create
.t.t column configure 0 -text Items -expand yes -button no
.t.t element create el1 text
.t.t style create s1
.t.t style elements s1 el1
set itm [.t.t item create]
.t.t item style set $itm 0 s1
.t.t item text $itm 0 "Hello World"
.t.t item lastchild root $itm

A more sophisticated example has been checked into the slicer3 svn (see [http://www.na-mic.org/ViewVC/index.cgi/trunk/Base/GUI/Tcl/ColorTree.tcl?view=log]). To try this, open the tcl interactor and type:
source $::env(SLICER_HOME)/../Slicer3/Base/GUI/Tcl/ColorTree.tcl
::ColorTree::ShowDialog
