Description
Processes mouse wheel motion.
If the ribbon is visible and the key tips are not, DoMouseWheelEx is called automatically when the user rotates the mouse wheel.
The Shift parameter indicates the current state of the Shift, Alt, and Ctrl keys.
The WheelDelta parameter indicates the distance the wheel was rotated. WheelDelta is positive if the mouse was rotated upward, negative if the mouse was rotated downward.
The MousePos parameter indicates the current position of the mouse pointer.
DoMouseWheelEx returns True if an event handler indicates that the event was found.
