OK, I'm trying to get dialogs to work the way I want. I have a 800x600 main window. I want to create a 400x200 dialog window in the center of the main window. I need to transfer data from the dialog back to the main window. I've been able to do this using a global. However I cannot fix the size of the dialog and center it in the main window. It appears at the bottom of the main window and covers the entire width.
Code is running on a RPi3 Raspbian w.matchbox window manager.

Gtk.main()As you can see, there's a bunch of redundant code I've played with trying to get the dialog to the size and location I want. Interestingly. self.get_size does return the size I want. It just doesn't display that size.
