How to get the files that not appear in the QTreeView

I'm use QTreeView with setFilter() function to allow to display the directories and drivers only but files does not allowed.

But I want to get the files that don't appear in QTreeView, with continue display the directories and drivers only without files in QTreeView.

QFileSystemModel dirsModel = new QFileSystemModel;
dirsModel->setRootPath("");
ui->treeView->setModel(dirsModel);
dirsModel->setFilter(QDir::AllDirs | QDir::NoDotAndDotDot);

How can I do that ?

As I said earlier you need to get entryList. For example:

void MainWindow::on_pushButton_clicked()
{
    QModelIndex ind = ui->treeView->currentIndex();
    QFileSystemModel *sys = qobject_cast<QFileSystemModel*>( ui->treeView->model());
    QString path = sys->filePath(ind);
    qDebug() << path;
    QDir dir(path);
    QStringList files = dir.entryList(QStringList(), QDir::Files);
    if(!files.size())
         qDebug()<< "Empty";
    else
        for(int i=0 ; i<files.size();i++)
            qDebug() << files.at(i);
}

We used QFileSystemModel here only to get current path, entryList is absolutely separate from this.
