I wrote a simple Dialog example and tried to add an outline to QLineEdit, but there is no effect.

#include "mainwindow.h"
#include <QLineEdit>
#include <QVBoxLayout>

MainWindow::MainWindow(QWidget *parent) :
    QDialog(parent)
{
   auto layout = new QVBoxLayout(this);
   auto lineEdit = new QLineEdit(this);
   lineEdit->setStyleSheet("QLineEdit { outline-color: red; } ");

   layout->addWidget(lineEdit, 0, Qt::AlignCenter);

   setLayout(layout);
}

what am I doing wrong?

Is this what you want to achieve?

lineEdit->setStyleSheet("border: 1px solid red");

Edit:

It really seems that the outline feature does not work as expected although it is documented in the reference. I think it is documentation bug because it was introduced afterwards, see QTBUG-26673. The outline in the example is for QPushButtons and does a different job than the outline CSS defines. You can see other examples for that here on SO, see: QT - CSS: decoration on focus So in summary I would conclude that the outline property is wrongly documented and can not be used for your purpose. You can file in Qt Bug report and see what the outcome is.
