Question

I’m new to GUI programming with python and gtk, so this is a bit of a beginners question. I have a function that is called when a button is pressed which does various tasks, and a TextView widget which I write to after each task is completed. The problem is that the TextView widget doesn’t update until the entire function has finished. I need it to update after each task.

Answer 1

After each update to the TextView call

while gtk.events_pending():   gtk.main_iteration() 

You can do your update through a custom function:

def my_insert(self, widget, report, text):    report.insert_at_cursor(text)   while gtk.events_pending():     gtk.main_iteration() 

From the PyGTK FAQ: How can I force updates to the application windows during a long callback or other internal operation?
