Property change notification
xargs1 last edited by xargs1
I found something unexpected with onChange signals. If I have
property int foo: 42 onFooChanged: console.log(foo);
This works as expected and I see nothing in the log unless foo is modified. But if I have
readonly property int init: 42 property int foo: init onFooChanged: console.log(foo);
I will get a change notification in the log when the application starts. Is this expected behavior? Can it be changed?

Well, you could bind to changed after | onCompleted?
I wouldn't get too hung up on just this if I found out unless it is affecting behaviour or functionality. I do act quite defensively to references to c++ null refs etc in qml and really act to cut rebinds away entierly.
To assist me greatly do this, early in main I turn on qt.qml.binding.removal.info category logging. e.g:
That way only the qt/qml objects produce rebind warning or if mine, only very determined rebinds, which I plan on eventually clearing those (currently just one) too.
