Whoops.

The line which in my code-fragment read:

gtk_signal_connect_object(GTK_OBJECT(button),"clicked",GTK_SIGNAL_FUNC(title_change), (gpointer) mainwindow);

SHOULD choke and die - I was casting to (gpointer) instead of GTK_OBJECT
(mainwindow).

However, this still gives:

Gtk-WARNING **: invalid cast from `(unknown)' to `GtkWindow'

Gtk-CRITICAL **: file gtkwindow.c: line 402 (gtk_window_set_title):
assertion `GTK_IS_WINDOW (window)' failed.

Hmmm...  Is the problem with my understanding of the GObject system?  I
suspect
that GTK_OBJECT "extracts" a part of the mainwindow.  If so, what is the
appropriate way to do this?  is it to create another window variable
which I then assign to the data variable?

Thanks again,
Bradley.
