I think JideScrollPane (as well as JScrollPane) supports horizontal wheel scroll. However vertical wheel scroll has a high priority. Only if there is no vertical scroll bar, it will scroll horizontally using wheel. So I guess you are looking for an option to make horizontal scroll a higher priority, aren't you?
I'm unsing a Microsoft mouse that allows to scroll horizontal and vertical. With this mouse I can scroll for example in Eclipse without problem. I'm looking for same behaviour.
I see. I wonder if Java MouseWheelEvent supports it at all. I didn't see a field in MouseWheelEvent tells if it's horizonal or vertical. It's no surprise that Eclipse works because it usually gets the native behavior.
