Description Jelle Geerts 2012-01-09 04:55:46 EET

If one wants to connect to the QObject 'destroyed' signal, it seems one can't
use an instance method. One instead needs to use a @staticmethod or
@classmethod (or lambda, etc.).

See the attached 'example.py'.

Comment 1 Jelle Geerts 2012-01-09 16:57:16 EET

In C++, Qt behaves the same, it just fails silently when using an instance
method of the same object that is destroyed after the 'destroyed' signal is
emitted.

It makes sense when reading the Qt source code, since the signal is emitted at
the very end in the QObject destructor.
