add Pixmap to QueryModel

[janus]

Hi,
I get a bool from the database and would like to display an image instead. But returning a Pixmap (or Icon) shows an empty cell. If i return the pic for the DecorationRole it is displayed. Any idea?
I have a subclass of QSqlQueryModel an the data() funktion looks like this:

QVariant SqlQueryModel::data(const QModelIndex & index, int role) const
{
	QString curr(QSqlQueryModel::data(index, Qt::DisplayRole).toString());
 
		if ( index.column() == 2 && role == Qt::DisplayRole ){
 
//			return QVariant(QString("sometext"));  // is displayed 
			return QVariant(QPixmap(":/somepic.png")); // is not displayed 
 
		}else{
 
			return QSqlQueryModel::data(index, role);
}
		}

QVariant SqlQueryModel::data(const QModelIndex & index, int role) const
{
	QString curr(QSqlQueryModel::data(index, Qt::DisplayRole).toString());
	
		if ( index.column() == 2 && role == Qt::DisplayRole ){

//			return QVariant(QString("sometext"));  // is displayed 
			return QVariant(QPixmap(":/somepic.png")); // is not displayed 

		}else{

			return QSqlQueryModel::data(index, role);
}
		}

To copy to clipboard, switch view to plain text mode

DisplayRole is meant to hold text and text only. Icons are displayed using DecorationRole. If you want to change this behaviour, you'll have to provide your own item delegate or use a proxy model that will take the icon from DisplayRole and return it as DecorationRole.
