        button=new JButton("Cancel");
        c.fill=GridBagConstraints.HORIZONTAL;
        c.insets=new Insets(10,0,0,0);
        c.gridx=4;
        c.gridy=2;
        pane.add(button,c);
     * Create the GUI and show it. For thread safety,
     * this method should be invoked from the
     * event-dispatching thread.
    private static void createAndShowGUI(){
        JFrame frame= new JFrame("GridBagLayoutDemo");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        addComponentsToPane(frame.getContentPane());
        frame.pack();
        frame.setVisible(true);
    public static void main(String[] args){
        javax.swing.SwingUtilities.invokeLater(new Runnable(){
            public void run(){
                createAndShowGUI();
}masters can you tell me what method I add to make the object never move once you maximize the frame?

Answer 1

If you want the JComponents to stay in the upper left of the JFrame, then just add the GridBagLayout JPanel to a JPanel that uses FLowLayout(FlowLayout.LEFT), then add this to the contentPane.
