      We embed qt and python in our application. When we run python code we don't need to create a QApplication (it already exists).

      Running:
       

      from PySide6 import QtCore, QtWidgets
combo = QtWidgets.QComboBox()
view = combo.view()
print(view.style())

      will throw:

      
RuntimeError: Internal C++ object (PySide6.QtWidgets.QCommonStyle) already deleted.

      The workaround consists in calling:

      QtWidgets.QApplication.instance()

      once (just after the import).

      But it would be nice not having to do that.
