Putting the comment at the bottom so that you can see that the code is indeed 7 lines long. And, there is nothing
done out of the ordinary to make it 7 lines long. There are no ; for example. OK, so the if statement is on one line
but that's the only place that you would traditionally see one more line. So, call it 8 if you want.
NOTE - the encoding format PPM has been shown to be significantly less CPU intensive than using PNG (thank you reporting PySimpleGUI user!)
In some cases however, PPM may not be supported. If you have problems with PPM encoding, then change ".ppm" to ".png" on line 8.

System Tray Icon
Your very own personsal status monitor in your system tray
Your very own peronsal status monitor in your system tray
Super easy to use.
1. Find an icon file or use this default
2. Create your menu definition
2. Create your menu defintion
3. Add if statements to take action based on your input
Note from the imports that this code works on all PySimpleGUI ports (except Web).
For the tkinter port, however, the icon isn't located in the system tray. Instead it's located just above
the system tray in the form of what looks like an "icon" on your desktop. It's actually a very small window.
In June 2021 a new package was added to the PySimpleGUI family - psgtray
With this package, you can get a real system tray icon while using tkinter rather than a desktop-icon that this
demo is demonstrating. The Demo Program - Demo_psgtray_Tray_Icon_Tkinter - shows how to integrate it with PySimpleGUI
