List Scrolling

["Demetris Zavorotnichenko" <fgcity4652 cytanet com cy>]

Hi to all.

I have a Tree View on a scrolling window. I need to be able to scroll it by
pressing on the tree and dragging it.

I need this since the application runs on a Touchscreen device so I don't
want to Drag the window Up and Down from the scroll bars but by pressing on
it and dragging.

How would I do this? I mean, if I take an event->y then I don't know the
direction. So how would this be done ?

Please help out guys.
