[PySide] What if a slot is not decorated with @Slot()?

[Cristián Maureira-Fredes]

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:
https://bugreports.qt.io/browse/PYSIDE-315
with some discussion as well.

I hope that helps,
Cheers
