class TGListTreeItem


TGListTree and TGListTreeItem

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).
