Use the Add method to add or replace skins to the control. The skin method, in it's simplest form, uses a single graphic file (*.ebn) assigned to a part of the control. By using a collection of objects laid over the graphic, it is possible to define which sections of the graphic will be used as borders, corners and other possible elements, fixing them to their proper position regardless of the size of the part.

The skin method may change the visual appearance for the following parts in the control:

• selected node, SelColor property
• borders of the nodes, Background property
• the background for all nodes, BackColorNode property
• node's background, BackColor property
