Class PanelEvent

java.lang.Object
  java.util.EventObject
      java.awt.AWTEvent
          de.schlichtherle.swing.event.PanelEvent

All Implemented Interfaces:

Serializable

public class PanelEvent
extends AWTEvent

Fired when the ancestor window of an EnhancedPanel is shown or hidden.

Note that since TrueZIP 6.1, this class has been refactored to subclass AWTEvent (which subclasses EventObject) instead of EventObject directly. This has been done in order to allow coalescing multiple events for the same cause by posting them to the AWT's Event Queue, from which the coalesced event would then be dispatched by AWT's Event Dispatching Thread.

However, since TrueZIP 6.4, these events are fired synchronously again, whereby it is ensured that only a single event is fired for each cause. The super class is kept for backwards compatibility only.

Since:

TrueZIP 5.1

Version:

TrueZIP 6.7
