Comment 22 for bug 1827696

Um, another quick question: The AbstractWaresDisplay now recalculates its columns when notified of a GraphicResolutionChanged. This works already, but when it becomes wider due to lower yres, the additional columns disappear behind the window´s border.
Which method(s) do I now have to call to make sure the parent Window resizes itself? layout(), update_desired_size(), set_layout_toplevel(), ... , and on what object (this, get_parent(), ...)?
