    - #### addMouseDownHandler

          HandlerRegistration addMouseDownHandler(MouseDownHandler handler)

      Notification fired when the user presses the left mouse button on this DrawItem.

      Note that if this item is part of a `DrawGroup`, then the group's `useGroupRect` setting affects whether this item receives the notification. If useGroupRect is true, then this item will not receive the notification. Otherwise, the item receives the notification and notification bubbles up to the group.

      Parameters:
        `handler` - the mouseDown handler
      Returns:
        `HandlerRegistration` used to remove this handler
