Problem With Setting Font to Display Text in a TextView

[Jim Orcheson <jim va3hj ca>]

Suppose I have an application with a window containing both a TextView 
and a FontButton. I want to display the text in the TextView using the 
font selected via the FontButton.

The Textview is called textview, and the FontButton is called 
fontbutton. Here is sample code in the on_font_set routine:

Pango::FontDescription *fd = new Pango::FontDescription;

fd->set_family(fontbutton.get_font_name());

textview.modify_font(*fd);


This works for a limited set of the fonts listed in the font selection 
dialog opened by clicking on the FontButton. If I select Arial, Arial 
Black, orTimes New Roman., the text in the TextView is displayed in the 
requested font; if I select any other font, the text remains in the old 
font.

What am I missing here?
