Edited text of question.

>> Dear Heyhey,

thanks :)

can you post some small compilable example, so that we can work directly on it ?

what's life without beer ! :)

ok !! i am going to send you the beer to your address at heyhey_@iname.com

thockit.

I can check your code tomorrow - but if you post it here, some other expert may solve the problem ...


beer time :)

where are you located ! :)

I think u can check the direction of movement by comparing the last coordinates of the event and the current one.

here is some drag-theWindow example code that works for me (IBM JDK1.1.7 / WinNT4WS)

you have to change your own code yourself :)

(I couldn't check your code yesterday - I found an old friend in this overcast country and we had very long beer 'discussion' ... :)

        Point p = getLocation();
        log("p: "+ p);
        int newX = p.x + (x - lastX);
        int newY = p.y + (y - lastY);
        log("new: " + newX + ", " + newY);
        setLocation(newX, newY);
        break;
      case MouseEvent.MOUSE_MOVED:
        log("mouseMoved: " + x + ", " + y);
        break;
      default:
        log("ERROR");
    }
  }  

  private void log(String st)
  {
//    System.out.println("" + st);
  }
 
  public static void main(String args[])
  {
    test t = new test(new Frame());
    t.setBounds(10, 10, 110, 110);
    t.setVisible(true);
  }
}

so can I lock this question ? :)

(btw. I won't be angry if you increase the points :)
