QScrollBar within a QMessageBox

[schall_l]

Hi,

I would like to use a QMessageBox in order to display the content of a txt file.
I am wondering if there is a possibility to activate an horizontal and/or a vertical scrollbar if the text from the file exceeds certain limits ?

This is my current code:

void 
MainWindow::credits() {
   QFile file(":/credits.txt");
 
   if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
      return;
 
   QMessageBox credits(QString("My Application"),file.readAll(),
                      QMessageBox::NoIcon,
                      QMessageBox::Ok,
                      QMessageBox::NoButton,
                      QMessageBox::NoButton,
                      this
                      );
 
   credits.exec();
 
   file.close();
}

void 
MainWindow::credits() {
   QFile file(":/credits.txt");
   
   if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
      return;
   
   QMessageBox credits(QString("My Application"),file.readAll(),
                      QMessageBox::NoIcon,
                      QMessageBox::Ok,
                      QMessageBox::NoButton,
                      QMessageBox::NoButton,
                      this
                      );

   credits.exec();
   
   file.close();
}

To copy to clipboard, switch view to plain text mode
