I have tried to make a Pixmap scroll on itself by using bitblt but it =
just will not work. If the object is a window then it does work - but, =
of course, this is not what I want.
Can anyone help?

So you are trying to bitblt a pixmap onto itself? If you don't want to
bitblt to the Window, then just create another pixmap buffer that you can
bitblt from one pixmap to the other... (triple buffering?)

I have thought of that and i may solve the problem that way - It just seems
so wasteful <sigh>..

Where is the rest of this Pixmap that is to be scrolled being stored. How is
that buffer maintained. It sounds as if you are doing for yourself what a
window will do for you. What is the purpose?
