@martin I take this opportunity to thank you for your tutorials, very good. One more time i take your code and modified it :blush:. For testing news scripts that is good, but i only have one problem. When I assign the code to a new button I need to restart my IDE. I use pycharm. Is it possible to solve this without other ways ? Thanks

Hi @DosSantos I missed this when you originally posted it -- I've fixed up the code now so it's clearer. Do you still have this problem/have you found a solution?
You're not the only person who has reported it, but I've not been able to reproduce it myself. That said, normally what I do when developing with Qt is to open a separate terminal (command prompt) and run the code from there. I started doing that when I was using an IDE which would die if the Qt app hung -- it's now just a habit!
Since you're usually just running the same command over and over, it's just a case of hitting the ^ arrow on the keyboard (recall last command) and pressing Enter to repeat.
Would be great to hear of other solutions though.
