I am a little out of the loop but the way it used to work was you made a font object and in there you can define its color, which font (eg courier new or system or whatever), size, and so on, and you apply that to the object in question (status bar's font, for example). If you don't have a font object it uses the window's default for that type of widget, which I think is tied to your current theme these days. I do not know if there is a way to get/set the existing font object without applying your own, you can poke around to see. It will be trivial to do once you find the command to change it or once you over-ride it and have your own variable.
