QPixmap from QVairant

[Talei]

Hello,
I have QStandardItemModel with QPixmap on first column. I want scale pixmaps but I can't figure out how to copy them back to tmp pixmaps.

QPixmap tmp = QPixmap( model.data( model.index( i, 0 ), Qt::DecorationRole ).toByteArray() );
//tmp is empty
//at index i,0 are Pixmaps

QPixmap tmp = QPixmap( model.data( model.index( i, 0 ), Qt::DecorationRole ).toByteArray() );
//tmp is empty
//at index i,0 are Pixmaps

To copy to clipboard, switch view to plain text mode 

Any suggestion are more then welcome.

EDIT:

qDebug() << model.data( model.index( i, 0 ), Qt::DecorationRole ).type();
//out: QVariant::QPixmap

qDebug() << model.data( model.index( i, 0 ), Qt::DecorationRole ).type();
//out: QVariant::QPixmap
