Hi,
Not sure if this will solve your particular problem, but I had a similar issue
with images disappearing at one point. The solution was to put the image widget
into an event box so it would get the redraw event.

Subject: Re: expose event
Does the image/video area have its own widget or is it on the same widget to
which the boxes/spin buttons were added ? If it is shares the same area then
you should consider putting the images/video area in its own widget i.e:
GtkWidget *drawing_area = gtk_drawing_area_new();
or write a widget class yourself.
It could also be your goal to let the boxes/spin buttons overlap the image
area... in that case I think its a little harder to get it fixed. Since i'm a
so called 'newbie' in Gtk/Gdk myself I can only base this answer on my Java/SWT
experience.

Douwe

Douwe,
Thank you so much for your response--that fixed my problem.
Another quick question that I think is related to this problem.
When I click on checkboxes or spin buttons, my image disappears. The
callback functions that are registered/connected for these check
boxes/spin buttons are defined to return void so I cannot return FALSE
with them to prevent a paint. Any idea how to resolve this one?
Thank again for your time.
