Andrew Borodin 83e3945c24 Ticket #2817: add mouse handler to the dialog.
Currently, dialog itself doesn't handle mouse events. It just
resends mouse event to each its widget. If we can several overlapped
widgets (especially, menu bar), there is some problem to decide which
widget must get event at first.
