Why do you only show the core or main parts of example code and not the imports? Every time I add a new line per your tutorial, I get an error trying to run it. I need to add to the import line. This causes more problems as often I do not know what to add.
Currently I am stuck on the toolbar QSize() line that was added. Python is complaining it doesn’t know what that is. This has happened the last 3 times I added something new. No one has mentioned this before? Everyone else knows what to add to their import lines but me? Very frustrating.
