Thanks Chris!
The question originated from the issue :
In my project, self.sender() in the downloadFinished slot sometimes returns
None instead of QNetworkReply, if comment the @Slot() ahead it seems to always
return QNetworkReply - works well. The same issue also happened to the slot
connected

History. Qt on Python predates decorators in Python.

Hi Zhao,
there is a configuration problem between Qt and PySide signals and
slots. The Qt signals and slots are assigned once at compile time.
On PySide, initialization is different since some things happen
earlier or later. There *can* be situations constructed which go wrong,
although doing
I initially expect that the aim of the decorator @Slot() is to make things
easier like this

and without the decorator , you'd expect write a little more code like
Hello,
The answer can be found in
https://code.qt.io/cgit/pyside/pyside-setup.git/tree/sources/pyside6/libpyside/dynamicqmetaobject.cpp#n557
The main idea is to register Slots (and signals) at parsing time,
before the connection is done.
An old issue can be find here:
The doc says:
It is really important to decorate each method declaration with a @Slot(), in
that way PySide6 knows internally how to register them into Qt.
But the method used as the slot works well even without the @Slot() decorator ,
I wonder if there is a risk in doing
