## javax.swing.event
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 JavaBeansTM has been added to the `java.beans` package. Please see `XMLEncoder`.

  `WindowEvent`, `WindowListener`, `JInternalFrame`, `InternalFrameListener`

### INTERNAL_FRAME_CLOSED

    public static final int INTERNAL_FRAME_CLOSED

  The "window closed" event. This event is delivered after the internal frame has been closed as the result of a call to the `setClosed` or `dispose` method.

  See Also:
    `JInternalFrame.setClosed(boolean)`, `JInternalFrame.dispose()`, Constant Field Values

### INTERNAL_FRAME_ICONIFIED

    public static final int INTERNAL_FRAME_ICONIFIED

  The "window iconified" event. This event indicates that the internal frame was shrunk down to a small icon.
