using mark-up in a combobox

[Ron Lockwood-Childs <rchilds vctlabs com>]

Hello,

I have an application in which it would be useful to display some 
entries within a combobox in bold type.  I have figured out how to do 
this with toggle buttons (get the label and turn on markup with 
gtk_label_set_use_markup( label, TRUE )).  However, I haven't found in 
the tutorials or API reference how to do the same in a combobox.  It's 
just a text combobox (I filled in the entries, including mark-up tags, 
using the glade-2 dialog box), which appears to contain a GtkListStore, 
but I'm a bit puzzled about how to enable markup for the entries.  Is 
markup the way to go for this, or is there some way to access individual 
text entries and change the pango properties?
