Re: [g-a-devel] Focus problems

Ashu,

If you are creating your own AtkObjects you will also need to deal with
focus notification. If you want gnopernicus to become aware that an
object has received focus you need to call atk_focus_tracker_notify()
for the object which has focus.

You could look at how we deal with this in gail.c.
