[C++-sig] pybindgen and PyQt

Thanks for the reply Gustavo.

Actually, it is the first scenario that I am after. Let me describe in
some detail what I am after (slightly simplified):

We have a C++ class that derives from the C++ Qt class QWidget. Lets
call it OwnWidget.  Several Qt methods expects pointers to subclasses
of QWidget, such as QLayout::addWidget(QWidget*). Using the PyQt
bindings I can create a python QLayout object.  Now, what I want to do
is create a pybindgen wrapped OwnWidget instance and pass it to the
addWidget method of the PyQt QLayout object.

The following pseudo-code illustrates what I want to do.  I tried it
using boost.python but without any luck.

C++:

    #include <qt/QWidget.h>
    class OwnWidget : public QWidget { ... }

python:

    import pyqt
    import ownwidget    # wrapped using pybindgen

    myWidget = ownwidget.OwnWidget()
    layout = pyqt.QLayout()
    layout.addWidget(myWidget)

Regards,
