Subject: [Lablgtk] Predicting width of rendered text

I want to calculate how many pixels of width would be needed to render a 
string in the current default font within a lablgtk app.  So far, I 
haven't been able to figure out how to do this.  I've tried looking at 
the styles of various on-screen widgets to get the font that they use, 
but this font seems unrelated to what is really displayed, as it stays 
the same even when I alter my system font defaults to change the real 
fonts used by the widgets.  I've also tried Gdk.Screen.get_pango_context 
and looking at the font within that context, but this font also seems to 
have no connection to what is really displayed.

Can anyone suggest code that would let me measure the pixels needed to 
render a string in the font that is being used in all of my widgets?
