The classic hack to update the progress bar without returning to the main loop is by running:

while (gtk_events_pending())

Still, be careful with this code because it can also trigger other queued events, such as user input, in places where you don't expect it.

A better approach is to structure your code so that a long-standing task is done in a separate thread, which uses idle_add to tell the GUI thread to update the progress bar (and anything else that might need updating).
