Checking current font?

[Rick Forrester <Richard Forrister jpl nasa gov>]

I need to determine the current font in use so that I can calculate the 
allowable line length for displayed text.  Have dug around in gdk & noted the 
font related width functions; but all have font as a parameter.

Have been wrestling my way through gdk & haven't managed to find a clean way 
to determine the font in use.  Would someone kindly point me at the correct 
way to make this determination?

TIA
