[PyQt] Quick question concerning protected member functions

[Christophe Diericx]

Hello all, 

I have posted a simple code example concerning my question here:
http://paste.pocoo.org/show/104256/.
It fails with a "RuntimeError: no access to protected functions or
signals for objects not created from Python".

I understand that this is in the documentation
(http://riverbankcomputing.co.uk/static/Docs/PyQt4/pyqt4ref.html#access-
to-protected-member-functions) and that this could probably solved in
this specific case by buiding a QLineEdit from Python and inserting it
into the QComboBox with setLineEdit().

But still, I was wondering:

* Does this happen with every C++ protected function /emitting of
signals or just in "some" cases?
* Is this scheduled to be possible in some future version of the
bindings or are there some intricate difficulties involved?

Thanks in advance.
