Overriden methods of C/C++ extensions

When subclassing a method of a class defined in a C/C++ extension, such as this example using the PyQt GUI framework:

from PyQt5.QtCore import QSize
from PyQt5.QtWidgets import QLineEdit, QApplication


class LineEdit(QLineEdit):

    def sizeHint(self):
        return QSize(128, 128)

app = QApplication([])
le = LineEdit()
le.show()
app.exec_()

vulture doesn’t detect that sizeHint is called via C++:

foo.py:7: Unused function 'sizeHint'

Maybe if a class inherits from a non-Python class, and an existing method is overridden, it should always be considered used?

Now that we have a repository for whitelist generators at https://github.com/RJ722/vulture-whitelist-generators, I think we can close this issue.

Hey Jendrik,

Ongoing action occurring at https://github.com/RJ722/vulture-whitelist-generators/tree/generate. I’ve an ongoing PR which is just one final review from @The-Compiler away from alpha release 1. 😛
