+"""
+    A System Tray Icon using pystray - No visible window version
+
+    Import the SystemTray object with this line of code:
+    from psgtray import SystemTray
+
+    Key for the system tray icon is: 
+        tray = SystemTray()
+        tray.key
+
+    values[key] contains the menu item chosen.
+
+    One trick employed here is to change the window's event to be the event from the System Tray.
+
+    This demo program keeps the Window hidden all the time so that it's a pure "System Tray" application.
+    Because the PySimpleGUI architecture implemented the tray icon using the psgtray package combined with the
+    overall window event loop, a Window object is still required.  The point of this demo is to show that this
+    window does not need to ever appear to the user.
