Thank you for giving this some thought. I think it is not the case
however that the gtk_widget_show_all() call causes the "widget to be
realized" in gtk-speak, it just sets a flag on the widget to say it
should be visible (I am guessing).

I think I have just made a breakthrough with my problem however -
setting the configure-event signal handler on the parent GtkWindow
widget instead of the GtkLayout window it contains causes it to fire
off. I have tried this with the scroll-event too and that works. Why
this should be different from the case where I use a GtkDrawingArea I
have no idea, but it looks like I am cooking with gas!

Thank you once more

Richard
