PySide2 not updating QLabel text when asked

Question

I am upgrading from Python 2.7 to Python 3.6 and from PySide to PySide2. I started by trying to get the \"Hello World\" from the \"Getting Started\" site (https://doc-snapsh

Answer 1

Fixed this problem on my Mac under python3.6 by adjusting the magic function:

def magic(self):
    self.text.setText(random.choice(self.hello))
    self.repaint()

The self.repaint() is needed for some reason, but at least works.

Answer 2

If you are running PySide2==5.15.0 then you need to upgrade it to 5.15.1 and thats what solved my problem.

Command to upgrade PySide2:

pip/pip3 install --upgrade PySide2
