I am new to Python and PySimpleGUI. I'm just playing around at the moment with the Everything Bagel sample program available from the PySImpleGUI website.
I have got the second window to work for changing the current theme, but I have been looking around for a way to update the main window, and all I can find is that the window needs to be closed and reopened.
I have attempted to put in a main function, but I expect this is where I have gone wrong.
I am getting the following error:
==== RESTART: C:\Users\brett\Dropbox\bmw\Lighting Programming\example 11c.py === Traceback (most recent call last): File "C:\Users\brett\Dropbox\bmw\Lighting Programming\example 11c.py", line 112, in 'The button clicked was "{}"'.format(event), NameError: name 'event' is not defined
The code I have manipulated from the main example is below:
