0042  *
0043  * A very simple event filter that returns when escape and return are pressed,
0044  * and as well, to emit a signal for the mouse event.
0045  *
0046  * This allows us to create our own focus model with widgets inside baskets
0047  * (although I'm not sure how useful this will all be after we port Basket to be
0048  * use QGraphicsView).
0049  *
0050  * Keypresses are filtered (i.e. the widget will not get the key press events),
0051  * but the enterEvent is not (for backwards compatibility).
