But I suppose I should add that not *all* attempts at widget trickery
fail. One of the trickiest widget manipulations I've come up with is
the hotkey widget, which allows textual events to be processed on draw
(or other) widgets, by hiding a text widget behind it (see posts from
last year). I use this technique in almost all of my widget
applications. So, by all means, keep pushing the limits.
Just don't be surprised if the limits snap.
