/*
* Nano-X GrGrabKey() demo program.
*
* Copyright(C) 2003 Jon Foster <jon@jon-foster.co.uk>
* Based on demo2.c
*
* This program allows the GrGrabKey() API to be tested.
* It creates a window, and displays key and hotkey events it recieves
* in that window. At startup it registers a key with GrGrabKey().
* The key and the registration type can both be specified on the
* command line.
*
* Usage:
* grabdemo key {n|h|x|s}
* Key is numerical MWKEY value (default 55='a').
* The second parameter is a single letter indicating the reservation
* type. Valid values:
* n - Normal (GR_GRAB_HOTKEY_EXCLUSIVE) (default)
* h - Hotkey (GR_GRAB_HOTKEY)
* x - eXclusive (GR_GRAB_EXCLUSIVE)
* m - Mouse (GR_GRAB_EXCLUSIVE_MOUSE)
