Creation/Dev/Script/Client/GuiTreeViewCtrl
Inherits GuiArrayCtrl.
Description
The TreeView control can display a tree structure similar to the Windows Explorer file view. Each node can have an icon and the text can be divided into several columns by using the columns offset array and tabulators in the node name. The TreeView control must be put into a GuiScrollCtrl to work properly.
