[Qt-interest] QVariant conversion problem

[Scott Aron Bloom]

QList< quint32 > is not a QList< QVariant >

I have some code where the relevant defns are as follows:

const QList<quint32> storytranslation_ids_by_lang

QMap<QString, QVariant>   where_data;
where_data["fk_storytranslation_id"] = QVariant(storytranslation_ids_by_lang);

g++ is complaining about the assignment in the final line, with the
following message:

error: no matching function for call to ?QVariant::QVariant(const QList<unsigned int>&)?
/usr/local/Trolltech/Qt-4.6.1/include/QtCore/qvariant.h:432: note: candidates are: QVariant::QVariant(bool, int)
/usr/local/Trolltech/Qt-4.6.1/include/QtCore/qvariant.h:425: note:                 QVariant::QVariant(void*)
/usr/local/Trolltech/Qt-4.6.1/include/QtCore/qvariant.h:222: note:                 QVariant::QVariant(Qt::GlobalColor)

<etc>

I can't see why, as there is a QVariant ctor as follows:

QVariant ( const QList<QVariant> & val )

Can someone suggest what I'm missing ?
