But show doesn't show the widget, it only schedules it to be shown during
the next run of the eventloop. Until that happens nothing is actually
drawn. And in your code you're adding the items directly after calling
show, so the eventloop doesn't run in between.

And btw, I didn't mean to say that adding 600 rows when the widget has
already been painted once should be slow.
