Hi, Mr Sven Neumann has given an excellent answer. Now I understand the difference between two functions (gtk_signal_connect and gtk_signal_connect_object).
I changed the parameters as suggested by Mr Neumann and viola! I am drawing the lines without "expose" event and only with pushing a button. Thanks. I Must also thank Jeff Trefftzs who gave similar views though in too abbreviated a form.
