Thanks for your comment. Yes I know, and I'm sorry for that but I pretty much had to explain everything in comments because it was a high school project and our teacher wasn't really familiar with Qt framework. And about the switch statement, you're right, I should have used an if in that case. The code looks kind of funny but at least it's good to see how much I've progressed during these months. I'll publish some of my recent projects soon!
