Qt Creator draw lines in tab widget

[Slofware]

Hello,

I am running python 3.4 with Qt Creator 5.
I can already draw some lines but that's all on the background.
Is there a way to always draw lines on the foreground or on a QTabWidget?

Thanks

I would guess that you need to create a widget inside the tab widget like QPainter to be able to draw lines

So I need to make a paintevent for the QTabWidget.
How do I do that in python and how can I update it every second?
