I have put a large tree (1500 items), on the left hand side of a horizontal split panel. Scrollbars appear, and it is scrollable. Nice! However, when I refresh the data in the tree, i would like to position it back to the top. Horizontal Split Panel doesn't have a setScrollPosition method.
I have tried wrapping my tree in a panel, and putting that in the horizontal split panel, but this doesn't work as the horizontal split panel appears to be showing the scroll bars, not the panel!
Can anyone tell me how to set the scroll position of the compenents in a split panel?
