+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
