JFrame without frame border, maximum button, minimum button and frame icon

Question

I would like to create a without frame border, maximum button, minimum button and frame icon.

Answer 1

Call setUndecorated(true) on your JFrame.

This method can only be called while the frame is not displayable (see JavaDoc).

Answer 2

This code Explains how you can achieve it.

Note: setUndecorated(true); statement in the constructor.

You cannot undecorate the Frame while it is already displayed.

public class MyFrame extends JFrame {

private JPanel contentPane;
private JTextField textField;

/**
 * Launch the application.
 */
public static void main(String[] args) {

                MyFrame frame = new MyFrame();
                frame.setVisible(true);

}
/**
 * Create the frame.
 */
public MyFrame() {
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setBounds(100, 100, 450, 300);
    contentPane = new JPanel();
    contentPane.setBackground(Color.ORANGE);
    contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));


    /* important Statement */
    setUndecorated(true);
}

}

Answer 3

Inside the constructor you can put code setUndecorated(true) it will disappear Frame.

For example: //This is constructor

public freak() {    
    super("Images");
    panel = new JPanel();
    ImageIcon image = new ImageIcon("C:\\Users\\shilu.shilu-PC\\Desktop\\2.jpg");
    label = new JLabel(image);
    add(panel);
    add(label);

    //Main thing is this one
    setUndecorated(true);
    //Just add this code in your constructor
}

Answer 4

You can the java.awt.Window class. A Window is like a JFrame, but with no borders.

Note that the Window class constructor needs a Frame (java.awt.Frame) as an argument, but you can set it to null. You can also extend the Window class to customize it like this:

public class MyWindow extends Window{
   public MyWindow(){
      super(null); // creates a window with no Frame as owner
      setBounds(x, y, width, height);
      setVisible(true);
   }
}

In main, you can create an instance of MyWindow instead of Window.

public static void main (String[] args) {
    Window window = new MyWindow();
    // Other stuff in main
}

I hope this helps!
