GUI - Change contentpane when button pressed

Hi everyone

I'm trying to change what shows up in the contentpane depending on what button you press. Say you press a button labeled "Customer", it would add textfields to the content pane.

I thought I could just add the action int eh actionPerformed method but doesn't seem to work.

Thanks for your help!

  1. public class ButtonDemo extends JFrame implements ActionListener
  2. {
  3.     public static final int WIDTH = 400;
  4.     public static final int HEIGHT = 300;
  5.     private JTextField nameField; 
  7.     public ButtonDemo()
  8.     {
  9.         setSize(WIDTH, HEIGHT);
  10.         WindowDestroyer listener = new WindowDestroyer();
  11.         addWindowListener(listener);
  13.         Container contentPane = getContentPane();
  14.         contentPane.setBackground(Color.WHITE);
  16.         contentPane.setLayout(new FlowLayout());
  18.         JButton customerButton = new JButton("Customer");
  19.         customerButton.addActionListener(this);
  20.         contentPane.add(customerButton); 
  21.     }
  23.     public void actionPerformed(ActionEvent e)
  24.     {
  25.         String actionCommand = e.getActionCommand();
  26.         Container contentPane = getContentPane();
  28.         if (actionCommand.equals("Customer"))
  29.         {
  30.             nameField = new JTextField("Hi everyone");
  31.             nameField.addActionListener(this);
  32.             contentPane.add(nameField);
  33.         }
  34.         else
  35.             System.out.println("Error in button interface.");

Call pack() after adding stuff to the content pane.

Sorry for the noob question but how would I do that? What would I put in the parameter of the Window header?

Thanks for the help!

Do you know where I can read up more of the pack method? It sort of does what I want but I'll have more than 1 button on the window, each button should populate the content pane with new fields. The pack() method displays the field and when I press the button again, it'll duplicate the fields. Also it breaks the set size of the window.

Better read up on Layout managers again then.Perhaps you could use CardLayout for this?
