Closing java program properly when JDialog is the main window

Question

I have JDialog as the main window in my application (originally it was a JFrame, but it displayed in the taskbar, which I don't need).

I am currently doing:

setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);

and when I press the exit button:

frame.dispose();

But the process still seems to be hanging in the background

JFrame had JFrame.EXIT_ON_CLOSEthat seemed to do what I wanted.

How can I close the application correctly?

Answer 1

You can add

  System.exit(0);

where you want to end the program, possibly right after the dispose () line.

WindowListener, System.exit(0), .

JDialog dialog = ...;
dialog.addWindowListener(new WindowAdapter() { 
    @Override public void windowClosed(WindowEvent e) { 
      System.exit(0);
    }
  });
