This is in part one-half of the issue I tried to raise
earlier in my email regarding "Smart Objects"... and it's the
tougher half.
One might not really 'need' to add "event objects" to
a smart object - smart objects themselves could be made to
"feed" events, "respond" to events, etc..
Right now, they do little of this since they are not
considered to be in the list of 'event-objects' that the pointer
lies in, even though they can be set, or not, to "pass" events..
a somewhat complex state of affairs.
Making smart objs "own" their member objects, thus helping
to solve some stacking-order issues, raises the other question:
What then for event-handling?
Should the current model be maintained? Or should smart
objs attempt to have the same event model as say one sees in
window systems?
