+    Demo Time Chooser
+
+    A sample window for choosing a time.
+
+    This particular implementation uses a Spin element.  Numerous possibilities exist for entering a time of day.  Instead
+    of Spin elements, Input or Combo Elements could be used.
+
+    If you do not want your user to be able to manually enter values using the keyboard, then set readonly=True in
+    the Spin elements.
