try this - it should work on both PC (F7/F8) and N8*0
Code:
#!/usr/bin/env python2.5
import gtk
from gtk import gdk
Has_hildon=False
try:
import hildon,osso
Has_hildon=True
except:
pass
class fontsize():
def on_key_press(self,widget,event,*args):
if event.keyval == gtk.keysyms.F7: self.fsize += 1 #inc
if event.keyval == gtk.keysyms.F8: self.fsize -= 1 #dec
Settings=gtk.settings_get_for_screen(gdk.screen_get_default())
Style=self.Style1 + str(self.fsize) + self.Style2
gtk.rc_parse_string(self.Style1 + str(self.fsize) + self.Style2)
gtk.rc_reset_styles(Settings)
def Quit(self,n):
gtk.main_quit()
def __init__(self):
self.fsize=12
self.Style1=\
"""
style "general-font"
{
font_name = "Sans """
self.Style2=\
""" "
}
widget_class "*" style "general-font" """
gtk.rc_parse_string(self.Style1 + str(self.fsize) + self.Style2)
if Has_hildon:
self.program=hildon.Program()
self.program.__init__()
self.window = hildon.Window()
else:
self.window = gtk.Window()
self.window.set_default_size(800,480)
self.window.connect("delete_event",self.Quit)
self.window.connect("key-press-event",self.on_key_press)
self.Lab=gtk.Label("This text should change size ...")
self.Box=gtk.VBox(True,0)
self.CBox = gtk.combo_box_new_text()
for f in ("Some Arbitary Text","Maemo Rules","N900 Rocks"):
self.CBox.append_text(f)
self.Btn=gtk.Button("Quit")
self.Btn.connect("clicked",self.Quit)
self.window.add(self.Box)
self.Box.pack_start(self.Lab,False,False,0) self.Box.pack_start(self.CBox,False,False,0)
self.Box.pack_start(self.Btn,False,False,0) self.window.show_all()
def run(self):
gtk.main()
if __name__ == "__main__":
try:
osso_context = osso.Context("net.nokia.fontsize","0.1",False)
except Exception,e:
if repr(e).find("NameError") == 0:
pass
else:
print "Error when testing for osso"
app=fontsize()
app.run()

This is not as complicated as it may look. It is still just gtk.rc_parse_string(), There is also the link to F7/F8 but the rest is really just a wrapper ( just copy/paste/chmod/run ) designed to test it.
I do think that if you were changing font size using daperls method and the container was not growing in size to accomodate it then you must be restricting it somehow. Are
you using set_default_size or set_size_request at all ?

Thanks Rick, that's a clean and elegant solution. It's the right solution. Theme-level changes are certainly the way to go. Luis, I think this is the solution you've been looking for since early June. Thanks again Rick, it works great.

Yes, it worked! Great.
I have one doubt, though: How can I use two types of fonts in the same app?
Thanks a lot!!

You will need to read up on gtkrc but you are not restricted to one style ie.
Style="""
style "button-font"
{
font_name = "Sans 18"
}
style "entry-font"
{
font_name = "pango_font_description"
}
class "GTKButton" style "button-font"
class "GtkEntry" style "entry-font" """
gtk.rc_parse_string(Style)

Just for the record, this is what I did.
I created a function with the following code:
and I call this function at the initialization of the program, and each time the variable self.font changes.
The only strange thing is that the GtkLabel works fine in the PC, but not on the N800: the label of the buttons remain unchanged, although the labels on the dialogs change. It seems that the gtk.ToggleButton is implemented differently in the different pythons.
Thanks for all your help!
