Disable mouse wheel scrolling shifting window

[LJHerskowitz]

I am trying to use the mouse wheel to zoom in on a graph. It isn't too hard to do using the mouse wheel event, but my problem is that when I scroll over the graph, the entire window shifts since its vertical scrollbar is visible. I do not want to turn this off, but I do want mouse wheel scroll functionality. When I scroll over a text box, the window does not shift. Is there a way to prevent the window from shifting so using the mouse wheel over the graph acts like using the mouse wheel over the text box?

Okay how about you detect the wheel move, and then if you saw a wheel move, move the pane back to where it should be.  Attached is a quick example that modifies the shipped example.  When you scroll the mouse wheel when over the picture the pane will shift, then shift back.  As a result you'll see a small shift up then back to where it was.  Not very clean but its a start.

That is true. I was thinking along those lines of turning off scrollbars and turning them back on, but for that to work I would need a Mouse Wheel? event (the mouse wheel does not trigger Mouse Down? event). But I was hoping for a less messy solution. Maybe I should suggest this in the idea forum.

An idea exchange would be a great idea.  Having a Mouse Wheel?  with a discard would be great.
