I have encounted anomalies regarding the delivery of events to
various widgets. By logging results obtained in handleEvent(Event evt)
methods, I saw that a Panel widget gets the full complement of the events
you would expect. Push Buttons only get a "action" event. Labels
donot seem to get any events. The full complement, which is specified
in the handleEvent method of Awt.Component, and perhaps the spec, is
case Event.MOUSE_ENTER:
case Event.MOUSE_EXIT:
case Event.MOUSE_MOVE:
case Event.MOUSE_DOWN:
case Event.MOUSE_DRAG:
case Event.MOUSE_UP:
case Event.KEY_PRESS:
case Event.KEY_ACTION:
It seems to me this event filtering is occuring somewhere in the
Solaris specific peer code. It seems very wrong.
