public virtual void DoWheel( 
   GoInputEventArgs evt
)

Parameters

evt

When the Control key is held down, rotating the mouse wheel changes the DocScale to "zoom" the view in or out at the current mouse point. Otherwise rotating the mouse wheel scrolls the view by calling ScrollLine. If the Shift key is held down, the scrolling is horizontal instead of vertical.

This is normally called from the GoToolManager.GoToolManager.DoMouseWheel method, to handle mouse wheel turns in the standard manner.
