I don't know about Gtk--, but in C I do this:

int cbSelectTable(GtkWidget *lista, int row, int col, GdkEventButton *ev,
gpointer data);

gtk_signal_connect_after(GTK_OBJECT(lista), "select_row",
GTK_SIGNAL_FUNC(cbSelectTable), NULL);


As you see, I can treat the GdkEvent as a GdkEventButton (GdkEvent is a "union"
type) which has time and button fields.
