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();
}
});
