Most come from the union-attr check, throwing errors because PyQt returns, for example, "QObjecet | None", so code is using attributes on the PyQt object that don't exist on None. In some cases, classes gained new overridden method implementations that do type narrowing to ensure a non-None object is returned. This also includes a new QListView subclass with the above overrides. With the new class, there is some light refactoring in ListCriteriaWidget, moving the selection methods to the new class. The test code (unit tests and module __main__) simply ignore union-attr errors, since we want that kind of runtime error to pop loudly. There are some remaining issues, but they seem to be issues in the PyQt5 typing. Signed-off-by: Chris PeBenito <pebenito@ieee.org>
