Parameters
- e
- An EventArgs that contains the event data.
Raising an event invokes the event handler through a delegate. The OnShapeChanged 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 OnShapeChanged in a derived class, be sure to call the base class's OnShapeChanged method so that registered delegates receive the event.
