How to display in a QListWidget for each item of a QStringList a QLabel and another QString? Qt c++

I retrieve a file list from a folder. For each file I would like to put its date (QString) and a QLabel. For each file these three elements would be put in a QListWidget. I recover all the files and the date correctly. The problem is that these two elements are in two different items. Moreover with this method, I can not put the QLabel in the QListWidget.

Here is my code :

viewList.h :

class viewList : public QWidget{
Q_OBJECT

public:
viewList();
QString getDate();

private:
QGridLayout *gridlayout;
QHBoxLayout *hboxList;
QVBoxLayout *vboxlist;
QPushButton *button;
QLabel *myLabel;
QListWidget *listwidget;

};

viewList.cpp:

viewList::viewList(){

gridlayout=new QGridLayout;
vboxlist=new QVBoxLayout;
hboxList=new QHBoxLayout;
//Button is outside the list 
button=new QPushButton("test",this);
myLabel=new QLabel("ok",this);

QString path="/home/myFolder";
listwidget=new QListWidget;

foreach(QString file, files){
    listwidget->addItem(file);
    listwidget->addItem(getDate());
}
vboxlist->addWidget(listwidget);
gridlayout->addWidget(button,0,0,1,1);
gridlayout->addLayout(vboxlist,1,0,1,1);
this->setLayout(gridlayout);

}

QString viewList::getDate(){
  return QDateTime::currentDateTime().toString("yyyy-MM-dd hh:mm:ss");
}

My three problems is that if I do listwidget-> addItem (myLabel) it does not work.In addition I would like to put the file and the label in a QHBoxLayout and the QHBoxLayout in a QVBoxLayout. But with my method I can not do it. Finally I would like QLabel, QString (date) and QString (file) to be in the same item.

Would anyone have an idea of ​​the method for doing this? For now I just show the file and the date in two different items.
