示例1: removeAWTEventListener
import java.awt.event.AWTEventListenerProxy; //导入方法依赖的package包/类
/**
* Removes an AWT event listener from this toolkit. This listener is no
* longer informed of any event types it was registered in.
*
* If a security manager is installed, it is asked first if an
* <code>AWTPermission("listenToAllAWTEvents")</code> is allowed.
* This may result in a <code>SecurityException</code> beeing thrown.
*
* It is not recommended to use this kind of notification for normal
* applications. It is intended solely for the purpose of debugging and to
* support special facilities.
*
* @param listener the listener to remove
*
* @throws SecurityException if there is a <code>SecurityManager</code> that
* doesn't grant
* <code>AWTPermission("listenToAllAWTEvents")</code>
*
* @since 1.2
*
* @see #addAWTEventListener(AWTEventListener, long)
* @see #getAWTEventListeners()
* @see #getAWTEventListeners(long)
