Timer Desktop Widget Creates a floating timer 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 SimpleGUI Can be used to poll hardware when running on a Pi
|
|
|
|
While the timer ticks are being generated by PySimpleGUI's "timeout" mechanism, the actual value
|
|
of the timer that is displayed comes from the system timer, time.time(). This guarantees an
|
|
accurate time value is displayed regardless of the accuracy of the PySimpleGUI timer tick. If
|
|
this design were not used, then the time value displayed would slowly drift by the amount of time
|
|
it takes to execute the PySimpleGUI read and update calls (not good!)
|
|
|
|
NOTE - you will get a warning message printed when you exit using exit button.
|
|
It will look something like: invalid command name \"1616802625480StopMove\"
