You shouldn't be using _get_size() at all in gtk3. This is the new height-for-width stuff that's new in gtk3. It's flexible, useful, and a pain. I learned it once when I ported viewnior to gtk3, but that's been a few years and I've otherwise forgotten it. Things to note that I do remember though are that calling gtk_widget_set_size_request will set the /minimum/ size of a widget and you won't be able to make it smaller than that. This is the best I can find right now that shows what it means:

I can also try to dig up what I did and help you out.
