[Qt embedded developer]

I am facing below error:

QML Connections: Implicitly defined onFoo properties in Connections are deprecated. Use this syntax instead: function onFoo(<arguments>) { ... }

I want to know when this type of error come ?

How to resolve this type of error ?

@Qt-embedded-developer I think what you're looking for is this:

Connections {
    target: Transition
    function onUnloadSource() {
        qmlFullScreenLoaderId.unloadSource();
        blockUserActivity.visible = ((qmlFullScreenLoaderId.strSourcePath.length == 0) || (Transition.isSys)) ? false : Transition.Timeout;
    }
}

The syntactic differences are subtle, but doing this should eliminate your error.

Hi,

As the message suggests: add the argument list in your onFoo function.

@SGaist can you elaborate this thing with example. because it's simple
code

Connections {
           target: Transition
           onUnloadSource: {
               qmlFullScreenLoaderId.unloadSource();
               blockUserActivity.visible = ((qmlFullScreenLoaderId.strSourcePath.length == 0) || (Transition.isSys)) ? false : Transition.Timeout;
           }
}

@Qt-embedded-developer please provide a minimal complete example.

Anyway, look at this and shows how to do this.
