JDialog Close button event

Question

For my custom JDialog,

setDefaultCloseOperation(javax.swing.WindowConstants.DISPOSE_ON_CLOSE);

has been set.

There is a button on the JDialog. Based on a condition, it calls dialog.dispose().

Both these actions trigger the windowClosed event. But I want to identify it reached there because the close button was clicked or because the dispose method was invoked.

Answer 1

Add a WindowListener to the JDialog, and on windowClosed set a boolean or something when it is closed. Also have a buttonClicked boolean, if they clicked the button it would be true, if they clicked the exit button at the top of the window it would be false.

boolean closed;
boolean buttonClicked;
JButton exitbutton;
JDialog dialog;
...
public void actionPerformed(ActionEvent arg0) {
    buttonClicked = true;
    dialog.dispose();
}
...
dialog.addWindowListener(new WindowListener() {

                public void windowActivated(WindowEvent arg0) {
                    // Do nothing
                }
                public void windowClosed(WindowEvent arg0) {
                    closed = true;
                    if(buttonClicked) {
                    //They cliked the button to close it.
                    } else {
                    // They didn't click the button, they clicked exit in the top right corner of screen.
                    }
                }
                public void windowClosing(WindowEvent arg0) {
                    // Do nothing
                }
                public void windowDeactivated(WindowEvent arg0) {
                    // Do nothing
                }
                public void windowDeiconified(WindowEvent arg0) {
                    // Do nothing
                }
                public void windowIconified(WindowEvent arg0) {
                    // Do nothing
                }
                public void windowOpened(WindowEvent arg0) {
                    // Do nothing
                }

            });
