well then, to avoid using casts to fool the compiler:
typedef gint (*this_particular_function_type)(GtkWidget *,
GdkEventButton *);
though this would also be possible:
typedef gint (*this_particular_function_type)(GtkWidget *,
GdkEventButton *,
gpointer extra_arg);
You can get this from the documentation at www.gtk.org, where it
describes each signal.
Or you could choose not to obey orders and use Gtk-- and forget all
this nonsense :))
