A list tree is a widget that can contain a number of items arranged in a tree structure.

The items are represented by small folder icons that can be either open or closed.

The TGListTree is user callable. The TGListTreeItem is a service class of the list tree.

A list tree can generate the following events:

kC_LISTTREE, kCT_ITEMCLICK, which button, location (y<<16|x).
kC_LISTTREE, kCT_ITEMDBLCLICK, which button, location (y<<16|x).
