Determining When a Frame or Window Is Opened or Closed |
|
|
Determination of opening or closing events of frames can be done by adding an instance of java.awt.event.WindowListener interface to that frame.
// Create the frame
Frame frame = new Frame();
// Create a listener for window events
WindowListener listener = new WindowAdapter() {
// This method is called after a window has been opened
public void windowOpened(WindowEvent evt) {
}
// This method is called when the user clicks the close button
public void windowClosing(WindowEvent evt) {
}
// This method is called after a window is closed
public void windowClosed(WindowEvent evt) {
}
};
// Register the listener with the frame
frame.addWindowListener(listener);
