When I scroll mouse wheel, map is zoomed in or out.  This is a nice feature.
In our application, there are cases that I want this behavior to be active or inactive.
For instance, I add a map into a "tab view".  If the tab view is NOT active, and I scroll the mouse wheel, I do not want the map to be zoomed in or out.
If the tab view is active, I want the map to be zoomed in/out when I scroll the mouse wheel.

How can I do this?
