I would like to know if it is possible to minimise my python program to the system tray.
Basically what it does is at every hour it takes a screenshot but I don't want it to stay on the task bar taking space. Could I make it go to the system tray area next to the clock but keep it running?
I am not using tkinter or anything like that.
Since you are running on Windows, you may simply want to rename your script to have a .pyw extension, so there is no console window. If you try to make a system tray application, you will need to pick a GUI toolkit like you've suggested, and your simple script will become a LOT bigger and far more complicated.
