This is not as complicated as it may look. It is still just gtk.rc_parse_string(), There is also the link to F7/F8 but the rest is really just a wrapper ( just copy/paste/chmod/run ) designed to test it.

I do think that if you were changing font size using daperls method and the container was not growing in size to accomodate it then you must be restricting it somehow. Are
you using set_default_size or set_size_request at all ?
