Control.OnMouseHover Method

Raises the MouseHover event.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

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

Parameters

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

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

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

The following code example demonstrates how to override the OnMouseHover and OnMouseMove methods in a derived class. To run the example, paste the following code in a new form and paste this class, forming the same file, after the form. Add a button of type FunButton to the form.
