Hi Josh,
After playing around with Tracking Events and
Sensitising/De-sensitising
slider widgets, I don't think that's the way to go.
However, I altered the properties of my Logitech wheelmouse's scroll
wheel from "click/select" to "horizontal scroll", and Voila!, on a test
GUI with a vertical and horizontal slider, only one slider would
respond
to the wheel button, whilst the other had to be clicked on as per
normal.
Setting the whell button property to "vertical scroll" had the expected
opposite effect, in that the other slider responded to the wheel, etc.
Not exactly platform or user independent though.
I seem to recall a recent post from one of the IDL Guri saying that he
was in the process of creating a DLM for mouse control. A search on
that
might prove fruitful.
HTH,
Andrew
