+    Demo Window Config Events
+
+    The Window object has a parameter enable_window_config_events that when set to True will
+    cause sg.WINDOW_CONFIG_EVENT events to be generated when the window is moved or resized.
+
+    Note that if you move the window using the Titlebar supplied by the operating system, then you
+    will only get an event at the end of the window being moved.  If you want to receive numerous
+    events during the movement, then you can achieve this using a grab_anywhere setting either
+    at the window level or on a single element as shown in this demo.
