PSUTIL Desktop Widget
|
|
Creates a floating CPU utilization window that is always on top of other windows
|
|
You move it by grabbing anywhere on the window
|
|
Good example of how to do a non-blocking, polling program using PySimpleGUI
|
|
Use the spinner to adjust the number of seconds between readings of the CPU utilizaiton
|
|
|
|
NOTE - you will get a warning message printed when you exit using exit button.
|
|
It will look something like:
|
|
invalid command name "1616802625480StopMove"
