Need help to control scrolling in the gallery [message #589389]

Hi,

I am using a Gallery and am adding (using drag & drop) images into the
gallery but don't seem to be able to stop the gallery repositioning itself
to the top.

I am using SWT.VIRTUAL and gallery.clearAll(); each time I add one or more
items into the middle of the "list";

I have tried: gallery.getVerticalBar().setSelection(scrollPosition);
but that didn't quite work. The scrollbar was set but the gallery was
still positioned at the top.

I also tried gallery.showItem(item); That works pretty well but the shown
Item can be anywhere ( top or bottom) so the page jumps about a bit
unexpectedly for the user.

Any help would be appreciated
Thanks
