Problem displaying 2 Frames

Question

So, I've got a little problem with the display.
I've mage a GUI with a frame and all is ok.
The main calls a methods which does a lot of things and after calls an other class which has to display a frame where I draw some lines thanks to paint.
the problem is that in the second frame, the content of the first is shown and on the content there are my paints. Does anyone know how to solve this problem in order that in the second frame , there is just my paint. (Because in the second frame, we see just the content, the buttons and all the things aren't ok.... and if I change the size of the second frame, there are a lot of stange things with the display of this frame...)
Thanks..

Answer 1

So here is some parts of my code.
My main class is UWB( )
It's like that :
package uwbrelease2;
import javax.swing.UIManager;
import java.awt.*;
import java.util.*;
public class Uwb
  //declaration d'une variable de test pour lancer cadre
  boolean packFrame = false;
  // debut du constructeur
  public Uwb()
    Frame1 frame = new Frame1();
    if (packFrame) {frame.pack();}
    else {frame.validate();}
    //Centrer la fen?tre
    Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
    Dimension frameSize = frame.getSize();
    if (frameSize.height > screenSize.height) {
      frameSize.height = screenSize.height;
    if (frameSize.width > screenSize.width) {
      frameSize.width = screenSize.width;
    frame.setLocation((screenSize.width - frameSize.width) / 2, (screenSize.height - frameSize.height) / 2);
    frame.setVisible(true);
  }  // fin du constructeur
  //m?thode principale
  public static void main(String[] args)
    try {UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());}
    catch (Exception e) { e.printStackTrace(); }
    new Uwb();
    Simulation simu = new Simulation();
    }//fin m?thode principale
}//fin class uwb[\code]
Here are some parts of Frame1( ) :[\b]
package uwbrelease2;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.border.*;
import java.io.*;
public class Frame1 extends JFrame {
  //Main UI panel
  JPanel contentPane;
  //Radio buttons that control the current panel
  JRadioButton Panel1Radio = new JRadioButton();
  JRadioButton Panel2Radio = new JRadioButton();
  JRadioButton Panel3Radio = new JRadioButton();
  ButtonGroup buttonGroup1 = new ButtonGroup();
  //Combo box and list of items that control the current panel
  Object[] dataObject = {"1 cm", "10 cm", "50 cm"};
  JComboBox jComboBox1 = new JComboBox(dataObject);
  //Card layout container panel
  JPanel jPanel1 = new JPanel();
  CardLayout cardLayout1 = new CardLayout();
  //Card layout panels and layouts
  JPanel jPanel2 = new JPanel();
  JPanel jPanel3 = new JPanel();
  JPanel jPanel4 = new JPanel();
  GridBagLayout gridBagLayout1_panel3 = new GridBagLayout();
  FlowLayout flowLayout1_panel4 = new FlowLayout();
  ..............................   and so on......
[\code]
Here is some part of simulation( ) :[\b]
package uwbrelease2;
import java.util.*;
import java.awt.*;
import java.io.*;
public class Simulation
//constructeur pour cr?er un objet Simulation
  public Simulation()
    try {
      doSimulation();
    catch (IOException ex) {
public void doSimulation() throws IOException {
    ZoneGraphique zone=new ZoneGraphique(tabMur);
    //zone.validate();
    zone.show();
where tabMur is an ArrayList .....[\b]
[\code]
[b]and finally here is ZoneGraphique ( ):[\b]
package uwbrelease2;
import javax.swing.*;
import java.awt.*;
import java.util.*;
public class ZoneGraphique extends JFrame {
  public ArrayList tabMur;
  public ZoneGraphique(ArrayList tabMur1) {
    super("visualisation");
    tabMur = tabMur1;
    setSize(500,500);
    try {
      DoZoneGraphique zone = new DoZoneGraphique();
      getContentPane().add(zone);
    catch (Exception e) {
      e.printStackTrace();
class DoZoneGraphique extends JPanel {
   public void paintComponent(Graphics comp){
     Graphics2D comp2D=(Graphics2D)comp;
   comp2D.setColor(Color.RED);
    comp2D.drawString("Floride",20,20);
   for (int j=0;j<=tabMur.size()-1;j++)
    Mur mur = (Mur)tabMur.get(j);
    comp2D.drawLine((int)mur.getAbs1(),(int)mur.getOrd1(),(int)mur.getAbs2(),(int)mur.getOrd2());
[\code]
So if you can help me, thanks .....[\b]
