[Qt-creator] A really minor observation about QML & properties

I don't _think_ this is how Qt APIs work though? Maybe I missed something, Qt classically has not used getXXXX() as a getter, but still provide properties and getters of the same name?  I had expected to be told something about how to change my declaration.

For example, QML Item instantiates QQuickItem. both have "clip".
 Q_PROPERTY(bool clip READ clip WRITE setClip NOTIFY clipChanged)

This is a property of Item, and a public function (getter) of QQuickItem. I assume there is some magic that tells QtC to know that when completing clip, to not add "()" ?

Also, for the member version, the docs don't say it, but I assume there is a standard setter generated with the if-value-change notify guard?
