And at my code is:
QApplication::setStyleSheet("new style: QTreeWidget {
background-image        :
url(/home/user/Desktop/Desktop3/ultracopier-general/ultracopier/src/styles/Oxygen/extra/background-playlist.png);
background-position     : center;
background-repeat       : no-repeat;
background-color        : #fff;
background-attachment   : fixed;
}");
