Glade editing

I think this may fall under newbe guestion.
Trying to edit the gaxis.glade. Would like to have the text in the jog increment window a bit larger. I have had the file open in glade editor and not sure if the font size can be edited. Is there documentation some where I could read, or someone who knows if this can be done?

unfortunately it looks like not easily.
You can change the displayed text fairly easily (it requires python code though in the handler file), but changing the displayed popup list seems harder - in fact I didn't find an example.

adding:
self.widgets.jog_speed.child.modify_font(pango.FontDescription("sans 18"))
to the def initialize_widgets(self): function in the handler file and adding
import pango
to the top of the handler file will do the first part.
