I think I understand what you're describing, but forgive me if
I don't!
You have one application window that contains a number of other
widgets (buttons, etc.) It's when you move the mouse into
and out of this window (the application) that you want to change
colour table, but at present it's changing as you move around
WITHIN this application. Is that correct?
have you tried creating a large base widget for the whole application
in which all the otehr widgets sit and turn on event_tracking
for this base widget, and turn it off for all the others. (I use
event_tracking in a similar way for a context sensitive help,
and I group a set of widgets in this way and connect the help to
their base widget instead of each individual widget so that I
can desribe them all in one go).
I don't know. This sounds like something you probably tried.
But then it might just be one of those obvious DUH! things :)
