Thanks for the suggestions. I won't be able to try
this for a bit but while I have your attention let me
ask some followup questions (hope you don't mind me
pickin your brain a bit!):
Does the ancestor event mean that the component is
displayed and in some kind of state of readiness?
I know JTable will propogate the event
isCellEditable() checked and blessed, but why is the
popup menu recieving it? Didn't the button consume
the event or doesn't the popup care if the event is
consumed?
If I return null, what happens to the display, I ask
because if my renderer is called to fast it messes up
some state information?
Do you know if I can use something like
getCellRect(row, col) to get a location for the popup?
The whole table is in a scrollpane, if the rectangle
is in table coordinates and if the table is the
invoker, where will the popup get displayed? Do I map
the rectangle x,y to the scrollpane or something?
Thanks for your time, really do appreciate it!
