Do you need to use idle_add()?
I have a Progress class I use to draw a progress bar on the screen and
show a spinner and all that. It does the while pending / iterate thing
too. My code looks something like:
init:
photo = gtk.Button('RTI Capture ...')
photo.connect('clicked', self.rti_capture_cb, None)
rti_capture_cb:
mark gui insensitive
enable progress feedback
while long_job():
do a bit of work
self.progress.update(percent)
hide progress feedback
mark gui active again
Code here, if it's any help:
