And there's the use case I was missing :-)

I read the doc for contentWidth a bit differently.
I believe it only gives width greater than Text.width if the wrapping is unable to wrap the text completely.
IE. If you have wrapMode: Text.WordWrap enabled and have a complete word that is longer than width, contentWidth will be set to that width.
If the wrap succeeds it will give the width of the wrapped content.

This is a bit clearer if you see the doc for wrapMode:
[quote]Text.WordWrap - wrapping is done on word boundaries only. If a word is too long, contentWidth will exceed a set width.[/quote]


I guess one workaround would be to center the MouseArea in the Text element and set the width of it to Text.contentWidth. (Have not tested it tho)
