Description Lucian 2010-07-23 08:04:34 UTC 
def l_cb():
    print 'hello'

GLib.timeout_add(100, l_cb)

TypeError: Error invoking GLib.timeout_add: Invalid callback given for argument function


Same thing happens with other functions for setting callbacks in GLib, like idle_add.

I'm using pygi 0.6.0.

Make error message less ambiguous

The problem is that timeout_add when accessed through introspection has an additional
priority argument (because it is really timeout_add_full).

Make error message less ambiguous

Accepting this with the note that we should refactor invoke to have a better parameter checking pipeline at some point.

Comment 4 Lucian 2010-07-27 13:39:44 UTC 
Then I suppose the bug is in GLib's introspection data, it should expose both timeout_add and timeout_add_full.
