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));

I figured it out:

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

Or

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

but watch out for the encoding.

This is better (conserves encoding): std::stod(ui->lineEdit->text().toUtf8()); – Jesko Jun 26 '22 at 09:56
