[Glade-users] glade_xml_signal_autoconnect and manual connection of signals

[giulio at hewle.com (Giulio Bai)]

Hello Tristan adn thanks for the help.

I've added the --export-dynamic flag to the compiler and passed the
info I needed using the user_data parameter and... it works! :)

I also added the g_object_unref () function so that my programs don't
consume ram useless.

Thanks again for the help,
Giulio
