Weird problem with QComboBox signal

Does anybody know how this message is possible at all?

Object::connect: No such signal QComboBox::"editTextChanged(const QString &)"

I also tried editTextChanged(QString &) and even editTextChanged(QString)

This happened when I tried to:

Code:

---

setDefaultProperty("QComboBox", "currentText", SIGNAL("editTextChanged(const QString &)"));

---

in order to:

Code:

---

wpage->registerField("ManufacturerName*", d->ui.manufacturerNameCombo);

---

Does anybody have a clue why this should not work? I'm using Qt 4.6.3 on Gentoo Linux. Thanks.

Skip the quotation marks. Then it should work.

Oops, beginner's problem. Thanks a lot.
