[pygtk] Updating a window

[Brian Rowlands (Greymouth High School)]

Thanks for that.

Do_stuff consists of things like:

	Impersonate a user
	Copy Db to c: drive
	Read sql DB and obtain PC settings
	Log-off certain types of users
	Change the registry
	Set printers inc default printer
	Write to a log file

	Etc

So event handlers doesn't seem to fix the bill in my mind. 

Roughly speaking, the GUI window displays a message to the user. Periodically, this changes as the login script runs through it's tasks. Even displays a goodbye message on the occasions the user shouldn't be allowed to log in.

When I used Perl, there was a window update function. Alas, I'm unsure of where to go now.

BTW, wrote GUI window in Glade if that makes any difference.

Would appreciate feedback

Thanks

The right answer really depends on what sort of things you are doing
inside do_stuff. If it's work that makes sense to move piecewise to
signal handlers, then do that. If it's a batch of work with convenient
locations to do event processing (say every time through a loop), call
gtk.main_iteration() from time to time, possibly within a while
gtk.events_pending().

Welcome to event-based programming!
