visibility mode for the scrollbars.













Fields
------

.. rst-class:: interim-class

.. class:: PolicyType
   :no-index:
   

   .. attribute:: ALWAYS

      The scrollbar is always visible. The view size is
      independent of the content.







   .. attribute:: AUTOMATIC

      The scrollbar will appear and disappear as necessary.
      For example, when all of a ``GtkTreeView`` can not be seen.







   .. attribute:: EXTERNAL

      Don't show a scrollbar, but don't force the
      size to follow the content. This can be used e.g. to make multiple
      scrolled windows share a scrollbar.







   .. attribute:: NEVER

      The scrollbar should never appear. In this mode the
      content determines the size.
