I'm a recent user of the gtk package and I found troubles trying to change the font in a multiline widget. I've seen the documentation for modules TexTag [1] and TextTagTable [2], but I was not able to do it. No compilation error, no runtime error, but no changes in the font.

Can anyone give me some pointers?
