D3- Invisible Scrollbars in ScrollBox


I am trying to make the scrollbars in my scrollbox invisible.
The scrollbox actually holds an image and the scrollbars are used as
a way of scrolling the image...  direct manipulation of the scrollbars
is not needed however so I would like to make the scrollbars invisiblee.

Currently I am moving the image using the code:

ScrollBox1.HorzScrollBar.Position := SCrollBox1.HorzScrollbar.ScrollPos
+ 10;

etc...  however... as soon as I make the scrollbars invisible the
image will not move..

Any suggestions on why this is happening and how to overcome this??

I have also tried to cover the scrollbars with panels or frames but the
scrollbox will not allow anything to be painted over the top of the

Thanks for your help :)
