John,
There's no 'gpointer user_data' on GTK2 anymore. But, is there any way to do the same thing ?Yes, this is all the same. Just connect to "clicked".http://developer.gnome.org/doc/API/2.0/gtk/GtkButton.html#GtkButton-clicked
Okay, but then my problem is with Glade2. On Glade 1 we still have the DATA field for the signal.
On Glade 2 is just missing. Thank you Marcos
