Delaying widget update

[Vince Busam <vince phatnoise com>]

  When I change the text on a bunch of labels on a slow computer, you can
see them all change one at a time instead of at once on the average
desktop PC.  Is there a way to delay this so all the labels are updated at
once, or do I have to draw into an offscreen pixmap instead?

Thanks,
Vince
