Mouse wheel for scrolling in subpanel

[gstanczak]

Can anyone tell me if there is a way to use the mouse wheel to scroll vertically in a subpanel window in 7.1? (I have the vertical scroll bar enable, and I have key focus set to true.)   I read that this is suppose to work for listboxes, is it suppose to apply to subpanels as well?

Thanks!

Greg

No way without writing code as far as I know. When I wanted to do something like this in LabVIEW 7.0, I had a loop which polled the wheel using the input VIs, and used that to generate a user event whenever there was a scroll. I then used that to set the FP.Origin property in the subVI to simulate a scroll. Note that you have to remove the subVI from the panel first, because you can't write the origin property to a VI in a SP.

So the order was -

1. defer updates in the caller (so the user doesn't see the VI being removed).
2. remove SP.
3. set origin (and make sure the user doesn't scroll past the end of the allowed area).
4. insert VI into SP.
5. undefer updates.

Great!  I will give that a try.
