[pygtk] How to prevent user-interaction with the UI?

[Ajay Garg]

Timo,
I wish to freeze the UI, while an operation is in progress.


Anyways, I am facing another problem. Now, while the root window is
frozen, and if I try to unfreeze a child widget - by
"set_sensitive(True) - it does not work.

Is it expected? If yes, is there a workaround?


Thanks and Regards,
Ajay
