示例1: removeFlavorListener
import sun.awt.EventListenerAggregate; //导入依赖的package包/类
public synchronized void removeFlavorListener(FlavorListener listener) {
if (listener == null) {
return;
}
AppContext appContext = AppContext.getAppContext();
EventListenerAggregate contextFlavorListeners = (EventListenerAggregate)
appContext.get(CLIPBOARD_FLAVOR_LISTENER_KEY);
if (contextFlavorListeners == null){
//else we throw NullPointerException, but it is forbidden
return;
}
if (contextFlavorListeners.remove(listener) &&
--numberOfFlavorListeners == 0) {
unregisterClipboardViewerChecked();
currentDataFlavors = null;
}
}
示例2: removeFlavorListener
import sun.awt.EventListenerAggregate; //导入依赖的package包/类
public synchronized void removeFlavorListener(FlavorListener listener) {
if (listener == null) {
return;
}
AppContext appContext = AppContext.getAppContext();
EventListenerAggregate contextFlavorListeners = (EventListenerAggregate)
appContext.get(CLIPBOARD_FLAVOR_LISTENER_KEY);
if (contextFlavorListeners == null){
//else we throw NullPointerException, but it is forbidden
return;
}
if (contextFlavorListeners.remove(listener) &&

}
}
示例3: getFlavorListeners
import sun.awt.EventListenerAggregate; //导入依赖的package包/类
