This is the code I use to increase or decrease font sizes: def font_decrease(self): font_size = self.font_desc.get_size() / 1024 font_size = font_size - 1 if font_size < 1: font_size = 1 self.font_desc.set_size(font_size * 1024) self.textview.modify_font(self.font_desc) def font_increase(self): font_size = self.font_desc.get_size() / 1024 font_size = font_size + 1 self.font_desc.set_size(font_size * 1024) self.textview.modify_font(self.font_desc) Apparently pygtk's idea of font size is based on something other than point size. I don't remember all the details but I'm pretty sure this is from the PyGTK tutorial, and it does work.

Anyway, they're currently running into some issues wrt to setting the font-size in their activity, please see the message below for details. Any help or pointers to possible solutions would be greatly appreciated!
