[Jason Dempsey <jasondempsey insightbb com>]

Ok i've tryed many things. But i keep getting parse errors when i try
something like:

void
on_button1_clicked                     (GtkButton       *button,
                                        gpointer         user_data)
{
void 
gtk_notebook_insert_page (GtkNotebook *notebook,
                                          GtkNotebook *child,
                                          GtkNotebook *tab_label,
                                                  ginit 1);
}

and i just can't seem 2 get it to work. Can anyone help me with this?
