Dear Florian,
Part 1 (module not found) I could solve by changing the Python
Interpreter in
Pycharm: '
File->Settings->Prioject Interpreter-> to C:\Program
Files\Python37\python.exe (Same as before, but other path)
Seems to be a virtual environment hassle.
Part 2:
Aarghhh, you are right. In that testing module I forgot the
QApplication... I've got it just a minute before your mail.
Thanks a lot for your attention
Hans
I have to shut down earlier ;-)

You most likely need to create a QApplication before using QPrinter.

Those paths are different. It looks like you have two PyQt5 installs
now, one
in C:\Users\myname\IR-Check_Tablet\ (without QtChart) and one in
c:\Program
Files\Python37 (with QtChart). According to the ImportError, you're
using the
former.
