18// TGListTree and TGListTreeItem //
19// //
20// A list tree is a widget that can contain a number of items //
21// arranged in a tree structure. The items are represented by small //
22// folder icons that can be either open or closed. //
23// //
24// The TGListTree is user callable. The TGListTreeItem is a service //
25// class of the list tree. //
26// //
27// A list tree can generate the following events: //
28// kC_LISTTREE, kCT_ITEMCLICK, which button, location (y<<16|x). //
29// kC_LISTTREE, kCT_ITEMDBLCLICK, which button, location (y<<16|x). //
