My opinion is that every widget inherits its pango context from its container parent. I don't think it makes a copy. But if it does, I would just make a recursive call starting at the top level window.
Maybe use the gtk.Container.get_children() call
The pseudo code might look something like this:
If a child doesn't make a copy, just change the toplevel window's pango context and then maybe call the toplevel window's check_resize().
Check gtk.Container for more info.

window.changePango(window)
def changePango (self, child):
if child is a container:
for subChild in child.get_children():
changePango (subChild)
else:
change the child's pango context

Please note my edits. My first pseudo code was out-to-lunch.
In fact, I changed the menu font and all its children and parents, without any success...
Thanks!

Code:
yes yes no
Code:
import gobject import gtk myContainer = gtk.Window() if gobject.type_is_a(myContainer,gtk.Window): print 'yes' else: print 'no' if gobject.type_is_a(myContainer,gtk.Container): print 'yes' else: print 'no' if gobject.type_is_a(myContainer,gtk.Label): print 'yes' else: print 'no'

However, I have a dialog box, and this changed the font of the "OK" button, but not the dialog text font...
Any clues?
Thanks once again!

From the gtk.Dialog reference page:
So, maybe you have to traverse these containers individually.
myDialog.vbox
myDialog.action_area
Attributes
"vbox" Read A gtk.VBox that is the main container of the dialog - all the other widgets are packed in it.
"action_area" Read A gtk.HBox that contains the buttons of the dialog.
myDialog.vbox
myDialog.action_area

I made a pygtk app, and want to use the +/- buttons to change the whole app font size (yeah, I'm becoming old quickly...). I know how to do that with pango in each widget, but I want to change ALL sizes at once.
Any help will be appreciated!
Thanks,
L.
