Thanks. Though it seems I would be duplicating the job of the window
manager, which generally figures out where to put the new window.

I wonder if it's possible to ask the window manager to place new
window on a specific screen programmatically. If not, I guess I
can juse use QDesktopWidget and pick a position at random :-)
