[Octave-bug-tracker] [bug #59829] Wrong font setting after start up in GUI

[Hg200]

Follow-up Comment #3, bug #59829 (project octave):

In stackoverflow they also say monospace causes problems with Qt5. The Qt
behaviour is very weired. I tried a bit and it seems to work for me with
following changes:

1.) Detect "monospace 9" instead of "DejaVu Sans Mono 9"

change
default_family = fixed_font.defaultFamily ();
to
default_family = fixed_font.family ();

2.) Set "monospace 9" instead of "DejaVu Sans 12". For this provide size when
QFont is called

change
QFont font = QFont (default_family);
to
QFont font (family, fixed_font.pointSize());

If i put this into Octave it starts with "DejaVu Sans Mono 9" in the editor
preferences. I have attached the code, but it is broken for Mac. And I don't
think it's a good idea to rely on a "try and fail" code. Who guarantees that
the code will work on other computers?
