Align to the right text from QLabel and QLineEdit

Question

I have a QLabel just below a QLineEdit with the same size and alignment properties:

QLineEdit *lineEdit = new QLineEdit(\"999\");
l

Would you be able to instead of using a QLineEdit and a QLabel to use two QLineEdits?

Consider the following:

QWidget* widget = new QWidget();
// Original line edit
QLineEdit *lineEdit1 = new QLineEdit("999");
lineEdit1->setFixedWidth(100);
lineEdit1->setAlignment(Qt::AlignRight);
lineEdit1->setStyleSheet("border-width: 2px;");
// A suggestion if you want a label
QLabel *label = new QLabel("999");
label->setFixedWidth(100);
label->setAlignment(Qt::AlignRight);
label->setStyleSheet("border: 2px solid rgba(255, 0, 0, 0%)");
// Alternatively if you can use another QLineEdit
QLineEdit *lineEdit2 = new QLineEdit("999");
lineEdit2->setFixedWidth(100);
lineEdit2->setAlignment(Qt::AlignRight);
lineEdit2->setReadOnly(true);
lineEdit2->setStyleSheet("background: rgba(0, 0, 0, 0%);  "
                         "border-width: 2px;              "
                         "border-style: solid;            "
                         "border-color: rgba(0, 0, 0, 0%);");
// Bring it all together
QLayout *layout = new QVBoxLayout(widget);
layout->addWidget(lineEdit1);
layout->addWidget(label);
layout->addWidget(lineEdit2);
widget->show();

It forces all borders to be 2px, so on different platforms it should be the same. The second QLineEdit should not look different than the QLabel (The text color looks slightly darker than that of the label though, which might be a good thing since it matches the original edit)

The added benefit of using a QLineEdit instead of the QLabel is that the value is now selectable...

Disclaimer: I have only tested on Linux and I have not done a pixel level comparison.

Edit: I see the alignment fails with different font sizes.
