[Sugar-devel] Screen Reposition?

[Art Hunkins]

With gtk.Label and gtk.Frame, I've been able to use the set_use_markup() 
property to get larger fonts, bold, italics, etc - by including XML markup 
in my text strings.

However, this property does not exist for gtk.Button.

Here is the relevent portion of a callback button that works fine (but no 
markup capability):

   def cbbutton(self,box,callback,title=""):
       butt = gtk.Button(" %s " % title)

I tried unsuccessfully to add markup capability to the title by modifying 
like this:

   def cbbutton(self,box,callback,title=""):
       label = gtk.Label(title)
       label.set_use_markup(True)
       butt = gtk.Button(" %s " % label)

Can this be made to work? (Sorry my PyGTK chops are so rudimentary.)
