[pygtk] How to increase font size of all widgets

[Volker Helm]

Hi,

I stumbled over a problem, that some people didn't like to use their googles or lenses. 
So I need to increase the size of the widget fonts by a factor. 
I tried to do it with pango. For me it is only working when I define for each widget a new class where the new size is defined.
Are there some general methods for it (I'd prefer not to generate a new gtkrc file for each user).

Thanks in advance,

Volker
