PySide Qt4 widget exchange in a hboxlayout

Question

I'd like to exchange a widget inside a QHBoxLayout. This code seems to work, but as soon as I do the actual app._exec(), the code crashes with terminate called after throwing an instance of 'boost::python::error_already_set'. Is there any way to get the actual error message? (or to resolve this problem)

gaParent = gameArea.parent().layout()
gaParent.removeWidget(gameArea)
gameArea = DrawingScreen()
gameArea.setObjectName("gameArea")
gaParent.insertWidget(0, gameArea)

Answer 1

I'm a C++ guy and not so much of a Pythonist, so excuse me if this makes no sense. However, from my perspective, it looks as if gameArea.parent().layout() returns a QLayout. That object does not have the insertWidget method.

Apart from that, I'm not sure where the boost::python::error_alread_set comes from. Can you do some intelligent printf-ing to try to determine when that boost error enters the picture?
