Or am I missing smth?
Hmm, maybe I'm missing something. The initial window isn't a "dialog", it's an application window. They follow slightly different rules (mainly, they don't have a parent window), but they still follow *rules*. > > > So why I somewhat agree with such a notion - it is not always a useful > > > feature. > > > Also, such an algorithm better allow me to save and restore the > > > geometry of the TLW. > > > > Why save and restore the geometry when the window manager can do a > > better job of positioning it?

In the second scenario, the primary monitor is at position (1920, 0). So you've just described exactly what a window manager does - follow rules to decide where the window appears - and NOT what happens if you remember geometry, which would be to put the window somewhere in the top left.

That's the WM's job. Let it do its job, and everyone's lives will be easier. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
