python - Dynamically adding checkboxes for each file in a directory PYQT5

Question

I want to dynamically add checkboxes for every file in a directory but when there's more than 10 files it just looks awful. So I need advice on how to tell the program that it should only add 5 checkboxes into one row and then move to the other. Thank you in advance.
