Just for the fun of it I've been playing with this for a few more minutes
and finally found something that seems almost usable ;)
The trick seems to be that we must use a timer to make sure the geometry
is set only after the dialog window shows up, which however causes an ugly
"flashing" effect. Besides that this code snippet seems to work ok, the
geometry is set to one third of the screen's width and height and the
dialog is centered on the screen.
