I don’t see a Popup in the code.   The code also seems to be missing the kv definitions for login and signup.

 

Please be clear about the issue you have having, and share a minimal runnable example.

Surely.

I am only working on the front end for now hence just doing the clicking and navigation.

So when you run the application it works, you will get the screen below

Click Login and no code is done to check this for now and this will take you to the home page like below

Click on CALENDAR and you will go to that section

CLICK THE + sign to right corner to add an event at this point the pop up menu will appear like below

And an event will be added to the main screen like above BUT when I press Cancel I want the event to be removed but the event stays like the image below.

The questions is how do I remove that event in the main screen when the Cancel button is clicked. Thank you.

how do I remove that event in the main screen when the Cancel button is clicked

 

From the layout that contains the event entry, call remove_widget(), and pass in the widget to remove.
