Detecting mouse scroll in an XControl

[GregSands]

Does anyone know whether it is possible to detect a mouse scroll in an XControl? Or do we need to wait for this event to be added?

Like I said in the idea, you can use the mouse input VIs to detect scrolling. It would just be a matter of ANDing that with the mouse cursor being over the XControl.

Definitely not a big issue, but this solution is not multi-platform (mouse input VIs are not available on Linux and Mac)

I've been trying to get this to work, but the Facade VI only runs in response to events, so I'm not quite sure where to put the mouse input VIs. I know I can do this outside the XControl, but I wanted to have all the functionality built into the XControl itself.

A valid point. Have a look at this recent thread which discussed spawning a parallel process and communicating with it. The daemon can be part of the XControl, so the users never see it.

Thanks, I hadn't connected that thread with what I was wanting to do. Will give it a go.
