Re: Non-UI events?

Hi,

I thing you have a simple way of doing this but I don't test it. If you
insensitive a widget which contains sub widgets, then sub widget are
also insensitive. So If all your widget are in a table, just do:

$table->set_state('insensitive');

and:

$table->set_state('active');

to reactivate them. You can also do it on the window or any other
widget.

Hope it works.
