xpMsg_KeyPress"5" The key press message is sent once per key that is pressed. The first parameter is the type of key
code (integer or char) and the second is the code itself. By handling this event, you consume the
key stroke.

Handling this message 'consumes' the keystroke; not handling it passes it to your parent widget.

Dispatching: Up Chain

Param 1: A pointer to an XPKeyState_t structure with the keystroke.
