Replacing virtual method of existing Gtk object in python

Question

My program has a DrawingArea which comes out of a UI file and is already existing when I want to replace get_preferred_height_for_width() of it.

My goal is to get a fixed aspect ratio of a child window (DrawingArea).

I've already tried Adding a Method to an Existing Object Instance but that does not seem to work. I can call the overridden function of the object by myself, but Gtk does not call it.

There must be a way to attach get_preferred_height_for_width behaviour to an existing Gtk object which comes out of a UI file.

What am I doing wrong? Any help?

I used Gtk.AspectFrame now. Seems to work ;) – pat Feb 18 '19 at 10:26 — pat, Feb 18 '19 at 10:26
