I'm using pylint on a program. It keeps pointing out an error of no emit

The code seems to work, so I am not sure if it is a false pylint error
or it is working some other way, even though I have subclassed setData
and as specified emitted dataChanged explicitly.
Could this be an artifact of the python/c++ nature of pyside?
Thanks,

Hey Ed,
most of the linters work mainly at a Python level,
and I expect them to fail when looking for Qt-inherited
members, which are usually not explicit.
In the case of a Signal,
we create that Python type with C-extensions,
so most of the behavior is manually written
https://code.qt.io/cgit/pyside/pyside-setup.git/tree/sources/pyside6/libpyside/pysidesignal.cpp
There you can see that we create the "emit" method of the type Signal
(line 177), so it should be picked up by autocomplete tools,
for example (in some IDE).
I'm not certain what's the process of pylint to detect the members,
but maybe you can ask the developers (or maybe on a public channel?)
to see what does they expect for the detection of members.
Do you have similar problems with Slots or Properties?
Cheers
