32/** Sligtly modified QApplication class.
33 *
34 * The sole purpose of this class (ATM) is to hook the macEventFilter
35 * in order to intercept Command-Q, Command-H and similar menu hot-keys
36 * before the HI Manager translate them into (menu) command events and
37 * start blinking menus in the menu bar.
38 *
39 * @remark
40 * A special hack in qeventloop_mac.cpp is required for this
41 * to work. Overloading QEventLoop::processEvents isn't feasable
42 * unfortunately, thus the horrible hacks. Qt 4 does seem to provide
43 * an interface similar to the one we create here.
44 *
45 * Btw. is QI* the right right way to do this? Or should it perhapse
46 * be called VBoxQApplication or something?
