How to call QObject.receivers() and QObject.isSignalConnected() in the right way?

[StarterKit]

Hi all,
Could anyone please provide a working example of how to use either QObject.receivers() or QObject.isSignalConnected() in python code?

I've found some examples written in C++ and some old topics for PyQt4... - maybe I'm stupid enough but I can't figure out how to do the same in python (I tried to play with QMetaObject and other things but without any sign of success. So I need help...)

[StarterKit]

The best option I found for isSignalConnected() is:

m_header = header.metaObject()
header.isSignalConnected(m_header.method(m_header.indexOfSignal("sectionDoubleClicked(int)")))

It works, but... looks a bit strange for me...

Just check the example given in the documentation

valueChangedSignal = QMetaMethod.fromSignal(MyObject.valueChanged)
if isSignalConnected(valueChangedSignal):
    data = QByteArray()
    data = get_the_value() # expensive operation
    valueChanged.emit(data)

@Pl45m4 , I tried it. Have it worked for you?
I have:
from PySide6.QtCore import QMetaMethod
signal = QMetaMethod.fromSignal(view_header.sectionDoubleClicked)
and it fails with:
AttributeError: type object 'PySide6.QtCore.QMetaMethod' has no attribute 'fromSignal'
This is the reason for my question.
