Python / glade fundamentals

[Doug]

Hi all,
Can someone tell me why I do not get a connection between the events and
the functions in the sample below. GUI window appears OK, just no
connections seem to be made.
I am new to this so may be missing something fundamental.
Thanks,
Doug

OK, I have solved the problem. The reference was a help. The clue is that
the events may not get passed through the parent. For reference here is
the code that worked.
It's good to finally get the basics working.

import gtk
import gtk.glade

def key_press(widget,event):
print "keypress"

xml = gtk.glade.XML('pgtest.glade')
widget = xml.get_widget('drawingarea1')

xml.signal_autoconnect({
"on_page_key_press_event": key_press,
"on_page_destroy_event": gtk.main_quit
})

gtk.main()

Hi Doug,
mabe you will find it easyer to use GladeGen to generate the
skeleton of your application rather then coding it yourself. Take a
look here: http://www.linuxjournal.com/article/7421

You may also use my PyGG module: http://freshmeat.net/projects/pygg

Franck:
PyGG seems pretty cool, thanks for the link!
