Mouse Wheel [message #437003]

What events does a mouse wheel generate? It doesn't seem to be any of the
Mouse events listed in the API for SWT, or any of the obvious keyboard
events.

Thanks,

Ken

It doesn't generate any events. See
https://bugs.eclipse.org/bugs/show_bug.cgi?id=7101 for details.

When you create a widget with V_SCROLL, the mouse wheel controls the
widget's vertical scroll bar. This works even when the scroll bar is
hidden (at least on Windows). I suppose you could listen for events on a
hidden scrollbar and reset it to a center position after receiving an event.
