Re: [gtk-list] synchronous exposure (how to do?)

[Joe Pfeiffer <pfeiffer cs nmsu edu>]

   Our program does a hard job at fetching a lot of data from a database at
   load time. So a progress bar would be the right thing to show. But since
   the expose event is handled at idle time (is this right?) the progress
   bar will not be drawn untill everything is loaded.

You want something like this:

void StatusWin::progress(int sofar, int total) {
	progressBar->update(((gfloat)sofar)/((gfloat)total));
	while (m->events_pending() >0)
		m->iteration();
}

(naturally, you'll want to translate into C)
