e565. 关闭的时候隐藏窗口

By default, when the close button on a frame is clicked, nothing happens. This example shows how to make the action hide the frame. One reason for hiding rather than disposing a frame would be to reuse the frame later.

    // Create a frame
    Frame frame = new Frame();
    
    // Add a listener for the close event
    frame.addWindowListener(new WindowAdapter() {
        public void windowClosing(WindowEvent evt) {
            Frame frame = (Frame)evt.getSource();
    
            // Hide the frame
            frame.setVisible(false);
    
            // If the frame is no longer needed, call dispose
            frame.dispose();
        }
    });
