Detailed Description

A specialization of QTreeView for manipulate layers.

This is a component used to manipulate layers in a visual way. You can add, remove, reparent items, changes its visibility, add folders and some other operations over a set of layers. It can be feeded by the LayersSelector or projects of TerraLib-5.
