Hi

Can any body let me know how can i write listener on ArrowButtons in Basic ScrollBarUI. in 1.5.(JscrollBar)

I Hope you tested it before you give.Becuse a Runtime Error is screwing me.

Iam attaching code how tried it and failed to solve.

Isn't AdjustmentListener enough for your purpose? At the end the position should only be changed by clicking the arrow buttons.
