Double Titlebar for JFrame in Swing

Yeah! I am excited to share this, a silly thing, but weird. Here is how to set a double titlebar for JFrame in swing, one comes with a default look and feel and the other is a normal title bar (based on OS).

Now, just see the image before the program.

import javax.swing.*;
import java.awt.*;

class DoubleTitleBar extends JFrame
{
JButton b;

    public DoubleTitleBar()

    {

        createAndShowGUI();

    }



    private void createAndShowGUI()

    {

        setTitle("Double Title bar");

        setLayout(new FlowLayout());

        setDefaultCloseOperation(EXIT_ON_CLOSE);

        b=new JButton("Button");

        add(b);



        setSize(400,400);

        setVisible(true);



        // This does the thing!!

        getRootPane().setWindowDecorationStyle(JRootPane.FRAME);

    }



    public static void main(String args[])

    {

        new DoubleTitleBar();

    }

}

getRootPane().setWindowDecorationStyle(): This method takes an int which can be a FRAME, PLAIN_DIALOG etc and sets the window decoration style, i.e. styles the title bar. Also see using setDefaultLookAndFeelDecorated()
