# Class InternalFrameEvent

java.lang.Object
java.util.EventObject
java.awt.AWTEvent
javax.swing.event.InternalFrameEvent

All Implemented Interfaces:
  `Serializable`

public class InternalFrameEvent extends AWTEvent
An `AWTEvent` that adds support for `JInternalFrame` objects as the event source. This class has the same event types as `WindowEvent`, although different IDs are used. Help on handling internal frame events is in How to Write an Internal Frame Listener, a section in The Java Tutorial.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans has been added to the `java.beans` package. Please see `XMLEncoder`.

  - `WindowEvent`
  - `WindowListener`
