  *       super().__init__()

  * Application.addDockWidgetFactory(DockWidgetFactory("hello", DockWidgetFactoryBase.DockRight, HelloDocker))
  *
  * @endcode
  *
  * One docker per window will be created, not one docker per canvas or view. When the user
  * switches between views/canvases, canvasChanged will be called. You can override that
  * method to reset your docker's internal state, if necessary.
