inserting rows performance with custom widget

How to improve loading data, inserting list items with custom widget using setIndexWidget(). The speed is terrible slow, without widget inserts much faster. The widget is a QLabel, which I need it to make a text as a hyper link.

Qt Code:

Switch view

QLabel *link = new QLabel(this);
    connect(link , SIGNAL(linkActivated(QString)), this, SLOT(openLink(QString)));
    nameLink->setText("<html><a href='"+fileID+"'><font color='#616E7F'>"+text+"</font></a></html>");
 
    QStandardItem *item = new QStandardItem;
    nameItem->setData(name, ListView::SORTBYFILEDATE);
    nameItem->setData(linkID, ListView::LINKID);
 
    model()->setItem(row, col, item);
    setIndexWidget(nameItem->index(),link);

QLabel *link = new QLabel(this);
    connect(link , SIGNAL(linkActivated(QString)), this, SLOT(openLink(QString)));
    nameLink->setText("<html><a href='"+fileID+"'><font color='#616E7F'>"+text+"</font></a></html>");
    
    QStandardItem *item = new QStandardItem;
    nameItem->setData(name, ListView::SORTBYFILEDATE);
    nameItem->setData(linkID, ListView::LINKID);
    
    model()->setItem(row, col, item);
    setIndexWidget(nameItem->index(),link);

To copy to clipboard, switch view to plain text mode

inserting about 20 items takes about a second

How QML about adding QML widget there ?
Thanks
