QSQLQueryModel + ListView in iconmode

Code:

iconmodel = new QSqlQueryModel();
    iconmodel->setQuery("SELECT `PictureForButtonMode` FROM `dictionary` WHERE `PictureForButtonMode` LIKE '%.%'");
 
    while(iconmodel->query().next())
    {
        QString buttonFV = iconmodel->query().value(0).toString();
 
            QString bttnPath = QApplication::applicationDirPath();
            bttnPath = "/home/dev/ttm/directory/icon/" + buttonFV;
 
 
                    // HERE IS WHERE I NEED TO TAKE buttonFV and make it into an icon i already 
                   // have it getting the string i just need to set it to a icon maybe how to set it in stylesheet ?
 
    }
 
 
 
    }
 
    if(!db.open()){
        qDebug() << db.lastError();
    }

I need to set the icon from my query if i could use my dir location + my string in a stylesheet that would be awesome or if theres another work around please let me know
