Java Swing，模拟事件驱动

EventQueue   queue   =   Toolkit.getDefaultToolkit().getSystemEventQueue();

 queue.postEvent(new   ActionEvent(CloseButton,   ActionEvent.ACTION_PERFORMED,   "close"));

 

ActionEvent can be replaced by MouseEvent below:

MouseEvent(btn,MouseEvent.MOUSE_RELEASED,0,MouseEvent.BUTTON1_MASK,1,1,1,false);  

 

There is better way to simulate Event in JAVA,  that is Robot.  Using it to capture screen and simulate mouse/keyboard event.  Below is an example to implement them which are mess and simple, but experienced programer should be able to understand it easily.
