Remarks
The OnMouseHover method performs a hit test to see whether the mouse is located over a TreeNode, and if it is, raises the NodeMouseHover event.
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
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(EventArgs) in a derived class, be sure to call the base class's OnMouseHover(EventArgs) method so that registered delegates receive the event.
