Slicer3:GUI Experiments:TkTreeCtrl

Background

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 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)
  • Model Hierarchy display properties (Alex)
  • EMSegment (Brad)
  • QueryAtlas (Wendy)
• Propose useful C++ API (all) for implementation by Sebastien and Yumin
