java中能实现当界面最小化后，仍能进行监听？

Question

急？如果有应该怎么做？如果没有又要怎么做？

Answer 1

最小化后的程序工作状态是不一样的，比如java程序无法监听界面外的鼠标事件
应该牵涉到操作系统一些监听事件

Answer 2

mainFrame.addWindowListener(new WindowListener() {   
            public void windowOpened(WindowEvent e) {   
                System.out.println("window opened");   
            }   
  
            public void windowClosing(WindowEvent e) {   
                System.out.println("window closing");   
            }   
  
            public void windowClosed(WindowEvent e) {   
                System.out.println("window closed");   
            }   
  
            public void windowIconified(WindowEvent e) {   
                System.out.println("window iconified");   
            }   
  
            public void windowDeiconified(WindowEvent e) {   
                System.out.println("window deiconified");   
            }   
  
            public void windowActivated(WindowEvent e) {   
                System.out.println("window activated");   
            }   
  
            public void windowDeactivated(WindowEvent e) {   
                System.out.println("window deactivated");   
            }   
        })
