Java/JDK 6/Dialog Modality

Demonstrating Modality Types

Improved Dialog Modality

import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JFrame;
public class ApplicationModalDialogDemo {
  public static void main(String[] args) {
    final JFrame parent1 = new JFrame("Parent Frame 1");
    parent1.setLayout(new FlowLayout());
    parent1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    JButton button = new JButton("Application modal dialog");

      public void actionPerformed(ActionEvent e) {
        JDialog dialog = new JDialog(parent1, "Application-Modal Dialog",

        dialog.setVisible(true);
      }
    });
    parent1.add(button);
    parent1.setBounds(100, 100, 200, 150);
    parent1.setVisible(true);
    JFrame parent2 = new JFrame("Parent Frame 2");
    parent2.setBounds(500, 100, 200, 150);

  }
}

Modeless Dialog

 
import java.awt.Dialog;
import java.awt.FlowLayout;
import javax.swing.JDialog;
import javax.swing.JFrame;
public class DocumentModalDialogDemo {
  public static void main(String[] args) {
    final JFrame parent = new JFrame("Parent Frame");

    parent.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    parent.setBounds(100, 100, 300, 200);
    parent.setVisible(true);
    JDialog dialog1 = new JDialog(parent, "Dialog1 - Modeless Dialog");
    dialog1.setBounds(200, 200, 300, 200);
    dialog1.setVisible(true);
    JDialog dialog2 = new JDialog(parent, "Dialog2 - Document-Modal Dialog",
        Dialog.ModalityType.DOCUMENT_MODAL);
    dialog2.setBounds(300, 300, 300, 200);
    JDialog dialog3 = new JDialog(dialog2, "Dialog3 - Modeless Dialog");
    dialog3.setBounds(400, 400, 300, 200);
    dialog3.setVisible(true);
    dialog2.setVisible(true);
  }
}

Using modality exclusion

 
import java.awt.Dialog;
import java.awt.FlowLayout;
import javax.swing.JDialog;
import javax.swing.JFrame;
public class ApplicationModalDialogWithExcludeDemo {
  public static void main(String[] args) {
    final JFrame parent1 = new JFrame("Parent Frame 1");
    parent1.setLayout(new FlowLayout());
    parent1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    parent1.setBounds(100, 100, 200, 150);
    parent1.setVisible(true);
    JFrame parent2 = new JFrame("Parent Frame 2");
    parent2.setBounds(500, 100, 300, 150);
    parent2.setVisible(true);
    JFrame parent3 = new JFrame("Parent Frame 3 - Excluded");
    parent3.setBounds(300, 400, 300, 150);
    parent3.setModalExclusionType(Dialog.ModalExclusionType.APPLICATION_EXCLUDE);
    parent3.setVisible(true);
    JDialog dialog = new JDialog(parent1, "Application-Modal Dialog",
        Dialog.ModalityType.APPLICATION_MODAL);
    dialog.setBounds(300, 200, 300, 150);
    dialog.setVisible(true);
  }
}
