how to serialize QMimeData

[Cyrille de Brebisson]

Hello,

I need to save and load a QMimeData object.

What is the easiest way to do this?

Thanks,
Cyrille

@Cyrille-de-Brebisson I would say you need to implement << and >> operators for QMimeData (see http://doc.qt.io/qt-5/qdatastream.html)

QDataStream &operator<<(QDataStream &stream, const QMimeData &data)
{
const QStringList formats = data.formats();
stream << (qint32)formats.size();
for(const QString& format : formats)
stream << format << data.data(format);
return stream;
}
QDataStream &operator>>(QDataStream &stream, QMimeData &data)
{
data.clear();
qint32 size;
QString format;
QByteArray formatData;
stream >> size;
while(size-->0){
stream >> format >> formatData;
data.setData(format,formatData);
}
return stream;
}
