Detailed Description

A collapsible treelist widget.

KTreeView is a class that provides a way to display hierarchical data in a single-inheritance tree, similar to tree controls in Microsoft Windows and other GUIs. It is most suitable for directory trees or outlines, but I'm sure other uses will come to mind. It was designed mostly with the above two functions in mind, but I have tried to make it as flexible as I can to make it easy to adapt to other uses.

Please read the source code if you have time. I have tried to comment it adequately and make the source understandable.

The class features the following:
