another PySide.jl question, how to set the parent to None
after removing a widget? If I attempt it I get the following error:
julia> pw_prm_sizer_0[:removeWidget](wd["fieldLabel"][1])
julia> wd["fieldLabel"][1][:setParent](None)
ERROR: PyError (PyObject_Call) <type 'exceptions.TypeError'>
TypeError("'PySide.QtGui.QWidget.setParent' called with wrong argument
