How to modify ScrollPane example2 to enable scrolling by scroll wheel?

Hello,

I can not figure out how to get scrolling by scroll wheel to work in ScrollPane example2. I have been poking around using explorer to try and figure out how the scroll wheel works in the Browser but have not discovered/recognized how it is supposed to work.

I have built an application based on ScrollPane example2 and it is working well, but it would be nice to get the scroll wheel to work before I get started on version 2.0. If I can get scrolling to work in the example, I think I can get it to work in my app.

Thanks,

John-Reed

The scroll wheel actually generates keyboard events (ctrl-up/down/left/right). You need to make sure the ScrollPane gets these keyboard events. See ScrollPane>>keyStroke:. Or you could call the ScrollPane's scrollByKeyboard: method in your own key stroke handler.
