Java Swing adding Action Listener for EXIT_ON_CLOSE
59,350
Solution 1
Try this.
addWindowListener(new WindowAdapter()
{
@Override
public void windowClosing(WindowEvent e)
{
System.out.println("Closed");
e.getWindow().dispose();
}
});
Solution 2
Another possibility could be to override dispose()
from the Window
class. This reduces the number of messages sent around and also works if the default close operation is set to DISPOSE_ON_CLOSE
.
Concretely this means adding
@Override
public void dispose() {
System.out.println("Closed");
super.dispose();
}
to your class MyGUI
.
Note: don't forget to call super.dispose()
as this releases the screen resources!
Solution 3
Write this code within constructor of your JFrame:
this.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
this.addWindowListener(new java.awt.event.WindowAdapter() {
@Override
public void windowClosing(java.awt.event.WindowEvent e) {
System.out.println("Uncomment following to open another window!");
//MainPage m = new MainPage();
//m.setVisible(true);
e.getWindow().dispose();
System.out.println("JFrame Closed!");
}
});

I have a simple GUI:
public class MyGUI extends JFrame{ public MyGUI(){ run(); } void run(){ setSize(100, 100); setVisible(true); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);// maybe an action listener here } }
I would like to print out this message:
System.out.println("Closed");
When the GUI is closed (when the X is pressed). How can I do that?
