Useful methods for a Window widget

  • set_default_size(200, 100) sets the default size of the window to a width of 200 and a height of 100; if instead of a positive number we pass -1 we have the default size.

  • set_position(Gtk.WindowPosition.CENTER) centers the window. Other options are Gtk.WindowPosition.NONE, Gtk.WindowPosition.MOUSE, Gtk.WindowPosition.CENTER_ALWAYS, Gtk.WindowPosition.CENTER_ON_PARENT.
