QPixmap from data in QStandardItemModel (QVariant)

[Talei]

Hello,
I have QStandardItemModel with some QPixmap (thumbnails) in it. What I want to do is to display that QPixmap into i.e. QLabel (setPixmap()) but I can't do that because model data() gave me a QVariant instead of QPixmap.
How can I convert/retrieve data from the model to QPixmap (data in model is as QPixmap).
Example:

ui->label_Img->setPixmap( model->data( model->index( 0, 1 ), Qt::DecorationRole ) );

ui->label_Img->setPixmap( model->data( model->index( 0, 1 ), Qt::DecorationRole ) );

To copy to clipboard, switch view to plain text mode 

Error, data is returned as QVariant.

Regards
