前提: 不使用 mouseMove来完成.

getPoint
public Point getPoint()

Returns the x,y position of the event relative to the source component.
Returns:a Point object containing the x and y coordinates 
         relative to the source component

应该可以的，所有的组件基本上都继承于java.awt.component，在这个类中，processEvent方法是专门用来传递各种awtEvent的事件的，如果你重载这个方法的话，每当有事件产生，这个方法就会被call，这是你就可以通过参数得到。方法如下。不过兄弟你这样何苦来的呢？

protected void processEvent(AWTEvent e) {
        if (e instanceof FocusEvent) {
            processFocusEvent((FocusEvent)e);

        } else if (e instanceof MouseEvent) {
            switch(e.getID()) {
              case MouseEvent.MOUSE_PRESSED:
              case MouseEvent.MOUSE_RELEASED:
              case MouseEvent.MOUSE_CLICKED:
              case MouseEvent.MOUSE_ENTERED:
              case MouseEvent.MOUSE_EXITED:
                processMouseEvent((MouseEvent)e);
                break;
              case MouseEvent.MOUSE_MOVED:
              case MouseEvent.MOUSE_DRAGGED:
                processMouseMotionEvent((MouseEvent)e);
                break;
            }

        } else if (e instanceof KeyEvent) {
            processKeyEvent((KeyEvent)e);

        } else if (e instanceof ComponentEvent) {
            processComponentEvent((ComponentEvent)e);
        } else if (e instanceof InputMethodEvent) {
            processInputMethodEvent((InputMethodEvent)e);
        } else if (e instanceof HierarchyEvent) {
    switch (e.getID()) {
      case HierarchyEvent.HIERARCHY_CHANGED:
processHierarchyEvent((HierarchyEvent)e);
break;
      case HierarchyEvent.ANCESTOR_MOVED:
      case HierarchyEvent.ANCESTOR_RESIZED:
processHierarchyBoundsEvent((HierarchyEvent)e);
break;
    }
}
    }
