Hello Phil,
While working on integrating Python into KDE4's Plasma I hit a crasher
when using @pyqtSignature where one of the arguments for the slot is a
typedef which in turn in a mapped type:
@pyqtSignature("dataUpdated(const QString &, const
Plasma::DataEngine::Data &)")
Plasma::DataEngine::Data is a typedef for QHash<QString,QVariant>.
This would crash when the signal is sent to the slot. After a heap of
debugging I've figured out goes wrong. When the signal comes in the
Plasma::DataEngine::Data type was being converted to QHash. Later when
sip looks for the mapped type in order to do the conversion, it can't
find what it is looking for but sip continues and dereferences a null
pointer.
The cause is in the code generated for the plasma module. The
typedefsTable looks something like this:
static sipTypedefDef typedefsTable[] = {
...
{"Plasma::DataEngine::Data", mtype_sat, "QHash", NULL},
...
};
The extra types for the QHash are stripped off. The table should look
more like:
static sipTypedefDef typedefsTable[] = {
...
{"Plasma::DataEngine::Data", mtype_sat, "QHash<QString,QVariant>", NULL},
...
};
cheers,
