[pygtk] input_add calling function only once?

[Federico Di Gregorio]

sorry if this is a FAQ or has already been discussed here. feel free to
send me to the ML archives. i was using twisted (and the gtk2reactor)
with pygtk 1.99.13 and everything worked fine. after an upgrade to .14
it stopped working and digging into the code i discovered that a
callback added using gtk.input_add does get called only once.

example program (foo will be called when you hit RET, but only once):

import pygtk ; pygtk.require('2.0')
import gtk
                                                                               
def foo(a, b):
    print "foo called with args:", a, b                                                
                                

gtk.input_add(0, gtk.gdk.INPUT_READ, foo)
gtk.main()

is this right? did it changed in latest gtk, pygtk or simply i dreamed
when i saw my glade2/gtk2/twisted application working?

thank you very much,
federico
