Get the value from a QLineEdit

Question

I have a QLineEdit that only allows numbers and I want to get the current value from it. I can't figure out how.

ui->lineEdit->setValidator(new QIntValidator(this));

Answer 1

I figured it out:

QString XMAX=ui->lineEdit->text();
xMax=XMAX.toDouble();

Answer 2

Or

std::stod(ui->lineEdit->text().toStdString());

but watch out for the encoding.

Answer 3

Try this:

ui->leNome->displayText()
