public class TDesktop
extends TWindow

TDesktop is a special-class window that is drawn underneath everything else. Like a TWindow, it can contain widgets and perform "background" processing via onIdle(). But unlike a TWindow, it cannot be hidden, moved, or resized.

Events are passed to TDesktop as follows:

• Mouse events are seen if they do not cover any other windows.
• Keypress events are seen if no other windows are open.
• Menu events are seen if no other windows are open.
• Command events are seen if no other windows are open.
