Have a problem in Modal dialog

Posted: Jun 27, 2003 3:52 AM

Hi,
In my application i have a JDialog having a default ok button. By pressing the button an error dialog will be shown. The problem is pressing the ok button continuously (holding it), will hang the application. Other than using a timer how can i fix this? pl. give me a solution as early as possible... A sample code is given below, having the same scenario.

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JOptionPane;
import javax.swing.JPanel;

/*
* @ (#)TestModal.java
*
* @version $Revision: $
*
* Date Created : Jun 27, 2003
* Latest Modification $Date: 2003 1:02:45 PM $
*
*/

*
*/
public class TestModal extends JDialog {

/**
* button for performing some action
*/
private JButton mActionButton = new JButton();

/**
* Default constructor
*/
public TestModal() {
super();
mActionButton.setText("Save");
JPanel panel = new JPanel();
panel.add(mActionButton);
this.getContentPane().add(panel);
mActionBu tton.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent e) {
button_actionPerformed();
}
});
this.getRootPane().setDefaultButton(mActionBu tton);
setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);
}

/**
* method invoked when an action is performed on the button
*/
private void button_actionPerformed() {
JOptionPane.showOptionDialog(this,
"Continuously clicking enter will hang the application",
"Title", JOptionPane.DEFAULT_OPTION,
JOptionPane.ERROR_MESSAGE,
null,
null,
null);
}

/**
* main method
*
* @param args command line arguments
*/
public static void main(String[] args) {
TestModal modalObject = new TestModal();
modalObject.setSize(100,100);
modalObject.show();
}
}

Thanks and Regards,
R. Renuka

you have a "dirty" solution... set a flag while the second dialog is opened.... and before opening a new one check for this flag.
