QSettings::value: Empty key passed messages

[TomFryers]

Specification

• pywebview version: 3.5
• operating system: Manjaro Linux KDE
• web renderer: Qt

Description

Running this simple example

import webview


class App:
    pass


webview.start(lambda _: None, webview.create_window("Test", html="", js_api=App()))

outputs

QSettings::value: Empty key passed
QSettings::value: Empty key passed

to the console. This is not a huge problem, but it’s a bit of noise.

Sorry for the late response. I could not reproduce this with QT 5.15.2 and latest master.

[TomFryers]

Neither can I, now, it seems! I had to reinstall my system, so it could be that, or an update or something.

The messages have returned. I've done some debugging and discovered that they are caused by calling QApplication([]) on line 659 in qt.py. The examples in the PySide2 docs always pass QApplication sys.argv, so I think it doesn't like being given an empty list.

I tried with the latest master and 3.6.2. The messages seem only to appear with QT_API=pyqt5 (which is the default). I'm using Arch Linux, KDE, Wayland.
