There doesn't appear to be a list of text-field validators

I was reading the doc for the QML SpinBox, one of whose properties is a "validator." It turns out that there are different kinds of validators, but there is no comprehensive reference to them that I can find. This document says only: "By default, SpinBox uses IntValidator to accept input of integer numbers." But it doesn't provide a list or even mention the other validators.

Version 5 and 6 examples are (there may be other controls that use a validator too):

https://doc.qt.io/qt-5/qml-qtquick-controls2-spinbox.html#validator-prop
https://doc.qt.io/qt-6/qml-qtquick-controls2-spinbox.html#validator-prop

The docs for other validators that I found through a string search for "validator":
