ScrollBar::OnMouseWheel Method (MouseEventArgs^)
.NET Framework (current version)
Raises the MouseWheel event
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
Parameters
The ScrollBar control will convert mouse wheel movements to scrolling when the ScrollBar is in focus.
Raising an event invokes the event handler through a delegate. For more information, see NIB: Raising an Event.
The OnMouseWheel method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors:
When overriding OnMouseWheel in a derived class, be sure to call the base class’s OnMouseWheel method so that registered delegates receive the event.
