Hi there all, I am having a weird problem in the following Applet
code,

<begin code>

public class MouseInputTester extends java.applet.Applet {
  private String msg = "";
  private int mouseX ;
  private int mouseY;
  static int i = 0;

  public MouseInputTester() {
    this.addMouseListener(new MouseInput());
  }
  private class MouseInput implements java.awt.event.MouseListener{
    private void setMousecoords(java.awt.event.MouseEvent me){
      mouseX = me.getX();
      mouseY = me.getY();
    }
    public void mousePressed(java.awt.event.MouseEvent me ){
      msg += "Mouse Pressed";
      setMousecoords(me);
      repaint();
    }
    public void mouseClicked(java.awt.event.MouseEvent me){
// msg="";
    msg += "Mouse Clicked ";
    setMousecoords(me);
    repaint();
    }
      public void mouseEntered(java.awt.event.MouseEvent me){}
    public void mouseExited(java.awt.event.MouseEvent me){}
    public void mouseReleased(java.awt.event.MouseEvent me){
      msg = "Mouse Released";
      setMousecoords(me);
      repaint();
      System.out.println(msg); // msg should have been set to "" in
paint, but that is justnot happening
    }
  }
  public void paint(java.awt.Graphics g){
    g.drawString(msg, mouseX, mouseY);
    msg = "";
    System.out.println("IN paint" + ++i );
  }
}

<end code>

The calls to System.out.println() are for debugging purposes only.

The problem is that when the applet is running, whenever mouse is
clicked the applet shows MouseRelasedMouseClicked, even though I set
the msg to "" whenever paint is called, the line with
System.out.println(msg) in mouseReleased() shows that somehow the call
to repaint() just did not occur, Am I missing any point on how the
paint method works.

I belive it is possibly because of the paint queue, that might be
maintained and from which only the most recent call to paint is
executed.

Even if you are on the right track you are going to get run over, if
you just keep sitting there.
