Re: How can I access gtk_tree_view declared in interface.c from callback.c ?

[André Pedralho <apedralho gmail com>]

I don't know if it will work, but you may try to use a pointer for
user_data like:
void on_new1_activate (GtkMenuItem *menuitem, gpointer *user_data)
then you can access an internal structure of this...
