HI Larry
Thanks for the reply. I have already implemented that using
Accessibility API. My red border windows dynamically move with the
shared windows. I get the size of the windows using accessibility API
and also the events corresponding to window move/minimise/maximise. So
this part is done with.
The problem I am facing now is to calculate the visible region
corresponding to the shared windows. SInce I am dynamically keeping my
windows over the shared windows, if i calculate the vis region of my
transparent red border windows on top of them then that will
effectively be the visible region of the shared windows.
