Open JFrame from JDialog and it shows on top of JDialog

Question

This is the scenario, My JFrame has a button it will open a JDialog when click it and it is a model dialog. JDialog has another button and i want to open another JFrmae open when click it.

Result : another Jframe open but it will not come to the top.It shows under the dialog.I want to open the 2nd JFrame on top of that dialog.

can use secondFrame.setAlwaysOnTop(true); but i don't have control to close it or move it.

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

import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JFrame;
public class FrameTest
{
    public static void main(String args[])
    {
        JFrame firstFrame = new JFrame("My 1st Frame");
        JButton button = new JButton("Frame Click");

        button.addActionListener(new ActionListener()
        {

            @Override
            public void actionPerformed(ActionEvent e)
            {
                JDialog dialog = new JDialog();
                dialog.setSize(100, 100);
                dialog.setModal(true);
                JButton button1 = new JButton("Dialog Click");

                button1.addActionListener(new ActionListener()
                {
                    @Override
                    public void actionPerformed(ActionEvent e)
                    {
                        JFrame secondFrame = new JFrame("My 2nd Frame");
                        secondFrame.setVisible(true);
                        secondFrame.setSize(400, 200);
                        secondFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                        secondFrame.setAlwaysOnTop(true);
                     }
                });

                dialog.add(button1);
                dialog.setVisible(true);
            }
        });

        firstFrame.add(button);
        firstFrame.setVisible(true);
        firstFrame.setSize(400, 200);
        firstFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }
}

look into modal types. Also, have you considered simply not using a jdialog and just using a frame instead? You have significantly more control over a frame (in my opinion). — TheOneWhoPrograms, Mar 07 '14 at 12:04

JDialog has another button and i want to open another JFrmae open when click it.

Don't do that. A tipical Swing application has a single main JFrame and several JDialogs. See this topic The Use of Multiple JFrames, Good/Bad Practice?

Result : another Jframe open but it will not come to the top.It shows under the dialog.I want to open the 2nd JFrame on top of that dialog.

Of course it does because the dialog is modal.

can use secondFrame.setAlwaysOnTop(true); but i don't have control to close it or move it.

It won't solve anything because the problem has to do with modality in dialogs. See this article: How to Use Modality in Dialogs to understand how modality works. There's an explanation in this answer too.

Try

secondFrame.setModalExclusionType(ModalExclusionType.APPLICATION_EXCLUDE);

It worked for me in the same situation.
