Components in a JApplet

Question

im not so sure if i should use a layout or anything, but basicly what i have is a JApplet, and i want to put text fields so that they are aligned in the center at the bottom. i want to add 6 components the the bottom and reserve the top portion of my applet for drawing. i want a 3 text fields and a JLabel for each and im having two problems setting this up.
1: i cannot get them on the bottom(the are created in the top center(with default layout)
2: after the applet is constructed and the fields and whatnot added, the Textfields wont show unless you click on where they are supposed to be(or you press tab while in one of the other text fields. after the textfields are shown for the first time i have no problems after this.
can anyone possibly suggest a solution to what i might be doing wrong?

Answer 1

this is my constructor and init methods
public class ThreeD extends JApplet implements MouseMotionListener, ActionListener, MouseListener
     private int windowWidth;
     private int windowHeight;
     private JTextField xval;
     private JTextField yval;
     private JTextField zval;
     public ThreeD(int width, int height)
          windowWidth = width;
          windowHeight = height;
          JFrame f = new JFrame("Window");//create new window
        f.addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent e) {System.exit(0);}//add a window listener
        this.setLayout(new BorderLayout());
        JPanel InfoPanel1 = new JPanel(new BorderLayout());
          JPanel InfoPanel2 = new JPanel(new GridLayout(1,6));//textfields
          JPanel InfoPanel3 = new JPanel(new BorderLayout());
          xval = new JTextField(4);
        yval = new JTextField(4);
        zval = new JTextField(4);
        xval.addActionListener(this);
        yval.addActionListener(this);
        zval.addActionListener(this);
        JLabel xtext = new JLabel("X:");
        JLabel ytext = new JLabel("Y:");
        JLabel ztext = new JLabel("Z:");
        xval.addActionListener(this);
        yval.addActionListener(this);
        zval.addActionListener(this);
          InfoPanel2.add(xtext);
          InfoPanel2.add(xval);
          InfoPanel2.add(ytext);
          InfoPanel2.add(yval);
          InfoPanel2.add(ztext);
          InfoPanel2.add(zval);
          JPanel bottomPanel = new JPanel(new GridLayout(1,3));
          bottomPanel.add(InfoPanel1);
          bottomPanel.add(InfoPanel2);
          bottomPanel.add(InfoPanel3);
          add(bottomPanel,BorderLayout.SOUTH);
          f.getContentPane().add(this,0);
          getContentPane().validate();
          f.pack();
        f.setSize(new Dimension(getWindowWidth(),(getWindowHeight())));//set the window size
        f.show();
          init();
     public void init()
          addMouseListener(this);
            addMouseMotionListener(this);
          setBackground(Color.BLACK);
        setForeground(Color.WHITE);
     my action listeners that are currently set to help me test this appletpublic void actionPerformed(ActionEvent e)
     public void mouseExited(MouseEvent e)
     {repaint();}
     public void mouseEntered(MouseEvent e)
     {repaint();}
     public void mouseReleased(MouseEvent e)
     {repaint();}
     public void mousePressed(MouseEvent e)
     {repaint();}
     public void mouseClicked(MouseEvent e)
     {repaint();}
     public void mouseMoved(MouseEvent e)
          System.out.println(e.getX() + " " +e.getY());
          repaint();}
     public void mouseDragged(MouseEvent e)
     {repaint();}paint and update     public void paint(Graphics g)
          System.out.println("Paint " + num);
          Graphics2D g2 = (Graphics2D)g;
          g2.setPaint(Color.BLACK);
          g2.fill(new Rectangle2D.Double(99,90,120,101));//repaints the backround
          g2.setPaint(Color.WHITE);
          g2.drawString(""+num, 100,100);
          num++;
     public void update(Graphics g)
          paint(g);
     and main
public static void main(String[] args) throws IOException , ClassNotFoundException
          JApplet applet = new ThreeD(1000,700, Objects1);
}note:not all code shown(just code that i think helps create and draw the applet)
