catching of wheel button / wheel scroll events? [message #38986]

Hi Guys
For a medical application the client requested that he can scroll
through a stack of images with a Logitech Wheel Mouse. Only one is
shown at a given time. That means I'll have to come up with an
solution to catch the wheel event. I have not found any documentation
how this can be done in IDL.

It might be possible to have an empty IDLgrWindow with scroll bars
invisible in back of my Draw Object, and then catch the OnScroll
Events. However, this seems to be a rather awkward solution.

I know that there's a OS issue with that and all, but we're simply
trying to make it as fast as possible for the radiologist.

Solution anyone?

Help is greatly appreciated!
Regards,
Stefan

Bitmask Mouse Button

4 Right
has no other documented options....
