gtk_object_set_data

["Lourdes Maldonado" <maldonado ibiquity com>]

I am using gtk_object_set_data to store some data and I want this
function call to trigger a callback but I can't figure which signal to
detect.  I was able to trigger the callback using the event signal but
then the callback gets triggered by a bunch of other events.

The widget sent to gtk_object_set_data is a GtkButton.

Thanks for any help
