Creating a Button in a JDialog

User_AYF65

Hi,

I have created a menuItem & when i press the menuitem a JOptionPane dialog box opens. I want to create a button in a dialog box when menuitem is clicked. I am not interested in JOptionPane. But my example code JOptionPane. Can somebody please guide me how to create a button in a dialog box?

import java.awt.*;

import javax.swing.*;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.JFrame;

import javax.swing.JMenu;

import javax.swing.JMenuBar;

import javax.swing.JMenuItem;

public class MainMenu2 implements ActionListener {

  JFrame f;

  JMenuBar jmb;

  JMenu jmFile;

  JMenuItem jmiOpen;

  MainMenu2() {

    f = new JFrame("Menu Demo");

    f.setSize(220, 200);

    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    jmb = new JMenuBar();

    jmFile = new JMenu("File");

    jmiOpen = new JMenuItem("Open");

    jmFile.add(jmiOpen);

    jmb.add(jmFile);

    jmiOpen.addActionListener(this);

    f.setJMenuBar(jmb);

    f.setVisible(true);

}

public void actionPerformed(ActionEvent ae) {

    ShowDialogBox(jmiOpen);

  }

  public static void main(String args[]) {

    new MainMenu();

  }

   void ShowDialogBox(Component parent)

    {  //JFrame f = new JFrame();

     JOptionPane pane = new JOptionPane(

          "New label", JOptionPane.QUESTION_MESSAGE

       );

      pane.setWantsInput(true);

      JDialog dialog = pane.createDialog(parent, "Enter Text");

      // Uncomment line and comment out next

      //  to see application modal

       JButton btn= new JButton("Send");

       btn.addActionListener(this);

       //pane.add(btn);

       dialog.add(btn);

       dialog.setModalityType(

       Dialog.ModalityType.APPLICATION_MODAL);

      dialog.setModalityType(

         Dialog.ModalityType.DOCUMENT_MODAL);

      dialog.setVisible(true);

    }

}

Right now its creating a JOptionPane style dialog box with OK button. I want to put a "send" button also.

Hi,

Thanks for your response. Sorry in the tutorial, i just found JOptionPane Dialogs. It shows limited features of Java. I thought we cant add Radio buttons  in the dialog box. Then i check it in the book & i got a program which i modified. If possible kindly add this program in the tutorial.

    JMenuBar jmb = new JMenuBar();

   

    JMenu file = new JMenu("File");

    JMenuItem item1= new JMenuItem("New...");

    file.add(item1);

    jmb.add(file);

    f.setVisible(true);

    f.setJMenuBar(jmb);

    MyMenuHandler handler = new MyMenuHandler();

    item1.addActionListener(handler);

   

    //MyWindowAdapter adapter = new MyWindowAdapter(this);

    //addWindowListener(adapter);

   

   

  }

   public static void main(String args[]) {

    new MenuFrameD();

   add(new JRadioButton("Green"));

   add(new JRadioButton("Orange"));

   tf = new JTextField();

    tf.setPreferredSize( new Dimension( 200, 24 ) );

   add(tf);

   JButton b;

   add(b= new JButton("Send"));

   b.addActionListener(this);

  }

  public void actionPerformed(ActionEvent ae){

     String t = tf.getText();

     //System.out.println(t);

     JOptionPane.showMessageDialog(null, t);

     dispose();

  }

}

      this.menuFrame = menuFrame;

    String comStr = ae.getActionCommand();

    if(comStr.equals("New...")){

       SampleDialog d = new SampleDialog(obj , "New Dialog Box");

       d.setVisible(true);

    }

   

  }

}

Oracle has a complete trial on Dialogs in its tutorial collection:
