I am not able to get any output on the browser

Question

This piece of code calculates the shift that the user will be on a given date. 3 x Shifts (Morning, Evening, Night) rotating every 5 weeks. Each shift has 2 x teams of techs. 1st team works on a Sun-Thu rotation 2nd team works on a Tue-Sat rotation

A GUI has been implemented with PySimpleGUI in order to make the code more user friendly. I tried running this in my web browser using PySipmleGUIWeb.

Starting the app in the browser I have no issues choosing the Day, shift etc. As soon as I hit the submit button nothing happens actually and I get the following output in the Pycharm console:

Returned from Remi Start command... now sending None event

Tried to get rid of the popup windows for the results and tried to just print them. I got no error but only the results in the PyCharm console instead of the web browser.

Any idea on how to make this work using the PySimpleGUIWeb?

Thanks a lot in advance.

Answer 1

The issue was the

window.close()

used in line 24. Moved it in line 111 and this works like a charm right now.
