You need to call QWidget's reparent() method. You can either do it in
Python or in C++...

- pass the address of the C++ parent into Python, use sip.wrapinstance()
to convert it to a Python object and call QWidget.reparent(), or...

- in Python extract the address of the C++ child using
sip.unwrapinstance(), pass it to C++ as a Python int object, convert it to
a C++ long, cast it to a QWidget pointer, and call QWidget::reparent,

- pass the Python objetc to C++, convert it to a void * using
sipConvertToCpp(), cast it to a QWidget pointer, and call
