NListtree class

This NListtree class is an ALPHA version.

The NListtree class is used to manipulate trees of lists.

A NListtree object can only be added to a NListview object at NListview creation time.

Despite NListtree class is declaretd to be subclass of NList class, just the attribute DropMark may be used wit a NListtree object and no NList class method may be used.

NListtree is a subclass of NListtree.mcc so you must have NListtree.mcc in MUI:libs/mui to use it. NListtree.mcc is copyright of Carsten Scholling.
