QDoubleValidator and setDecimals

Why this code not work:

Code:

---

QDoubleValidator *qv= new QDoubleValidator(parent);
qv->setDecimals(2);
editor->setValidator(qv);

---

The number takes all decimals, not only 2

Because you can enter also: 1.234567e4.

Use a reg exp validator with a regexp set to "\d*\.\d{1,2}" instead if you want to disallow the scientific notation. Remember about escaping backslashes.
