After a comparison with the documentation of QML TextInput (inherited by Ubuntu.TextField), I found that some properties/signals are missing.
wrapMode:
Set this property to wrap the text to the TextInput item's width. The text will only wrap if an explicit width has been set.[1]
N.B. Documentation for Ubuntu.TextField's contentHeight/Width reports a wrapMode property that is not actually aliased in the root item.
editingFinished()
This signal is emitted when the Return or Enter key is pressed or the text input loses focus. Note that if there is a validator or inputMask set on the text input and enter/return is pressed, this signal will only be emitted if the input follows the inputMask and the validator returns an acceptable state.[2]
This QML signal was introduced in Qt 5.2.
