    For QLineEdit , I tested it . I found that it is not suitable because QLineEdit is 1 line text editor . I need to show text with multiple lines .And the text should be read-only text. That's why text edit or text browse is the most suitable for me.
    So is there another widget that textedits can be added ??

    @Kinesis If the text is read-only why not simply add it using http://doc.qt.io/qt-5/qlistwidgetitem.html#QListWidgetItem-2 ?

    QListWidgetItem *item = new QListWidgetItem(icon, "some text");
    listWidget->addItem(item);

      read-only text means text inside textedit is read only.plz take alook my code and u will understand clearly.

      for(const QFileInfo & finfo: directory.entryInfoList()){
          m_textEdit = new QTextEdit;
          QFile data(finfo.absoluteFilePath()) ;
          data.open(QIODevice::ReadOnly);
          QTextStream stream(&data);
          QString content = stream.readAll();
          data.close();
          
          
          m_textEdit->setText(content);
          m_textEdit->show();
          ui->listWidget->addItem(m_textEdit);
      }
      

      The problem is that I cant add textEdit on listWidget easily .

        @Kinesis Sorry, but I still don't get why you need a QTextEdit? QListWidgetItem already can show text:

        for(const QFileInfo & finfo: directory.entryInfoList()){
            QFile data(finfo.absoluteFilePath()) ;
            data.open(QIODevice::ReadOnly);
            QTextStream stream(&data);
            QString content = stream.readAll();
            data.close();
            
            QListWidgetItem *m_textEdit = new QListWidgetItem(content);
            ui->listWidget->addItem(m_textEdit);
        }

            @Kinesis But what is wrong with my code? It should show the text inside the QListWidget.
            Your picture shows each text in its own window - is this what you want?!

                @Kinesis My question was whether you want to show it in a WINDOW like in your picture.
                And can you explain why you need a QTextEdit to show read-only text if you already can show text in QListWidget? I really don't understand that.

                    like this(only example):

                    ui->listWidget->setFlow(QListView::LeftToRight);
                    ui->listWidget->setGridSize(QSize(110, 90));
                    ui->listWidget->setResizeMode(QListView::Adjust);
                    ui->listWidget->setViewMode(QListView::ListMode);
                    ui->listWidget->setWrapping(true);
                    
                    for (const QFileInfo &finfo : directory.entryInfoList()) {
                        [...]
                        auto    item = new QListWidgetItem("", ui->listWidget);
                        auto    text = new QTextEdit(content);
                        text->setMinimumSize(100, 80);
                        ui->listWidget->setItemWidget(item, text);
                    }
