Hi,
I am able to get nsWidget not nsWindow interface but unable to repaint
the invalid region after that also.
Can I overload chrome window event loop and then inside trap NS_PAINT to draw
my own drawing .
If posible please help me wth some code.
Neeraj

Hi,
IMO, the nsWindow interface is being hidden for security reason.
Note that nsWindow.h is not in the mozilla/dist/ directory.
The only way to redraw is when the region is part of
your own widget. And to create your own widget, do a
search on "custom widget" in the xpfe mailing list.
(I've tried to compile and include nsWindow and BaseWidget libs
independent of mozilla and it did not seem to work.)
Steve
just my 2 cents.
