I discovered that the semantics with signals taking typedefs as
arguments has changed with respect to previous releases of PyQt and SIP.
To make one of PyQwt's examples (PickerDemo) work with PyQt v4.5 and
earlier releases I have code like:
if PYQT_VERSION < 0x040500:
picker.connect(picker, SIGNAL('selected(const QwtPolygon&)'), slot)
else:
picker.connect(picker, SIGNAL('selected(const QPolygon&)'), slot)
where I have the following typedef
typedef QPolygon QwtPolygon;
in one of my SIP files. Is this change a bug or a feature?
