This sample creates a button that displays itself with one of three different bitmaps, depending on its state. The button has a bitmap for: the unpushed state; the hover state (when the mouse moves over the button); and the pushed state. Default bitmaps are included with the sample, but you can override these properties to use your own bitmaps.
This sample uses the following keywords:
