hard time with swing

[Faiz Abdelhafid]

Hello Guys

How can I make the drawn text moving with this thread ?


thread class

 

public class MovingThread extends Thread {

  InsidePane pane=new InsidePane();

    public MovingThread() {
    }


    @Override
    public void run(){

      int x=pane.getPosX();
      int y=pane.getPosY();

      while(x<pane.getWidth()){
          x++;

      }

      pane.setPosX(x);
      pane.repaint();


      try{

          Thread.sleep(2000);

      }catch(InterruptedException e){

          e.printStackTrace();
      }


    }

}



  

panel class

   

public class InsidePane extends JPanel{


    private int posX=20;
    private int posY=20;
    private String str="Test";

    public int getPosX() {
        return posX;
    }

    public void setPosX(int posX) {
        this.posX = posX;
    }

    public int getPosY() {
        return posY;
    }

    public void setPosY(int poxY) {
        this.posY = poxY;
    }


    public void paintComponent(Graphics g){

        g.drawString(this.str,this.posX, this.posY);

    }

}



 

frame class

   


import gui.newpackage.*;
import threads.newpackage.*;
import javax.swing.JFrame;


public class MainWindow extends JFrame {

    InsidePane pane= new InsidePane();


    public MainWindow() {

        Thread mvt=new MovingThread();
        this.setSize(400,400);
        this.setContentPane(pane);
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        this.setVisible(true);
        mvt.start();


    }



}




 

test class

    

public class test {

    public static void main(String args[]){

            MainWindow mw=new MainWindow();
            

    }




}

Thanks
