GWindow key events are not forwarded to the event queue as GEvents.

[htiek]

The GEvent type supports a KEY_EVENT category which includes KEY_PRESSED, KEY_RELEASED, and KEY_TYPED. The GWindow type, however, does not generate GEvents in response to a KEY_EVENT.

I think (?) it's due to the following. The GWindow type wraps an _Internal_QMainWindow object. The _Internal_QMainWindow::keyPressEvent function forwards to the superclass is a QMainWindow, which does not override keyPressEvent, so the super call goes to QWidget, which only uses keyPressEvent to handle window closures. Afterwards, _Internal_QMainWindow::keyPressEvent calls GWindow::processKeyPressEventInternal, which does nothing. That would probably be the place to add the hook to add a corresponding GEvent to the event queue.
