How can I remove all the listeners associated with a component?

John Zukowski

Prior to 1.3, there was no way to ask a component for its list of listeners. You had to manually track them yourself. Starting with 1.3, you can ask certain AWT/Swing objects for said list of listeners, then remove them. Since Component has a getListeners(Class) method, all components have support this. See http://java.sun.com/j2se/1.3/docs/guide/swing/ListenerChanges.html for a list of non-component objects that support this.

[FAQ Manager Note] To remove all listeners prior to 1.3, you can simply create a new instance of the component in question and replace the old component with the new one.

Note that the getListeners() method will only work for the standard AWT events that Component tracks (and is overridden for each subclass). If you create your own subclass, you must override it to access any events that you add. See the source for java.awt.Button for an example of how to properly override getListeners().
