code: public void refresh()
      {
          final WiresShapeControlHandleList list = _loadControls(IControlHandle.ControlHandleStandardType.RESIZE);
  
          if (null != list)
          {
              list.refresh();
          }
      }
docs: If the shape's path parts/points have been updated programmatically (not via human events interactions),
  you can call this method to update the children layouts, controls and magnets.
  The WiresResizeEvent event is not fired as this method is supposed to be called by the developer.
