35 * Base class for frame, panel, canvas, panel items, dialog box.
40 * Event handler: windows have themselves as their event handlers
41 * by default, but their event handlers could be set to another
42 * object entirely. This separation can reduce the amount of
43 * derivation required, and allow alteration of a window's functionality
44 * (e.g. by a resource editor that temporarily switches event handlers).
