Protected Overridable Sub OnMouseLeave ( _
	e As EventArgs _
)

protected virtual void OnMouseLeave(
	EventArgs e
)

protected:
virtual void OnMouseLeave(
	EventArgs^ e
)

abstract OnMouseLeave : 
        e:EventArgs -> unit 
override OnMouseLeave : 
        e:EventArgs -> unit

Parameters

e: Type: System..::.EventArgs
An EventArgs that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

The OnMouseLeave 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 OnMouseLeave in a derived class, be sure to call the base class's OnMouseLeave method so that registered delegates receive the event.
