[CLOSED] I am not sure ,and is this a bug?

I want to control a window when it is dragged,so I add a dragListener to it,this is my test code:

public class WindowTest implements EntryPoint {
private Window w;
public void onModuleLoad() {
w = new Window();
w.setSize(300, 300);
w.setUrl("http://www.163.com");
w.show();
DragListener dragListener = new DragListener() {
@Override
public void dragStart(DragEvent de) {
System.out.println("start"+"***"+w.getHeight());
}

@Override
public void dragMove(DragEvent de) {
System.out.println("move"+"***"+w.getHeight());
}

@Override
public void dragEnd(DragEvent de) {
System.out.println("end"+"***"+w.getHeight());
}
};
w.getDraggable().addDragListener(dragListener);
}
}


after I drag it the print result is:

start***0
move***0
move***0
end***300

that means the size of the window is missing when dragStart and dragMove,but I really need to know it because I want to control the region where window can be dragged to.Is this a bug? If not what can I do if I want to satisfy my purpose?

No it is not a bug. The window is not visible while dragging as you drag the proxy
