  Progress Bar
  ============
  
  .. versionadded:: 1.0.8
  
  .. image:: images/progressbar.jpg
      :align: right
  
  The :class:`ProgressBar` widget is used to visualize the progress of some task.
  Only the horizontal mode is currently supported: the vertical mode is not
  yet available.
  
  The progress bar has no interactive elements and is a display-only widget.
  
  To use it, simply assign a value to indicate the current progress::
  
      from kivy.uix.progressbar import ProgressBar
      pb = ProgressBar(max=1000)
  
      # this will update the graphics automatically (75% done)
      pb.value = 750
