How can I get the application QmlEngine ?

@KroMignon I'm on QT 5.12.3 so that could save me. Will tell you, thanks !

@KroMignon My binding loop error hasn't changed at all even with "qputenv("QT_LOGGING_RULES", "qt.qml.binding.removal.info=true");" in my main.cpp file .. Am I condemned to live in this infinite binding loop ? haha

Can you show the QML code which is not working well?

Here is my main.qml file :

Item {
id:root
visible: true
width: 640
height: 480
property var mainMenu: Menu{rootStack: root}

StackView {
    anchors.fill: parent
    id: menuStack

    property var button: hmiclass.button
    initialItem: mainMenu

    onButtonChanged: {
        mainMenu.onButtonPushed(button)
    }
}
}

EDIT: I need to find where that loop is coming from.. Or to find a patch to refresh only the bindings which are in the translation file.

This is the one

@kmarconi And what is the binding loop error message? I can't see any obvious error on this code extract.

@KroMignon Sorry, the error is : QML StackView: Binding loop detected for property "button"

According to your code, it looks like mainMenu.onButtunPushed() will change hmiclass.button content, which will recall mainMenu.onButtunPushed()...

@KroMignon Yeah that's what I tought but why this error is only showing on retranslate and not on the app boot too ?

Because there have to be a first change to start the loop!
I don't know what is changing hmiclass.button?

I suppose hmiclass is a C++ class instance and button is a property of this class.
In some way the attached signal to this property is emitted, which will start the loop.

That is just an hypothesis, I don't have a clue about your code.

@KroMignon Yeah sorry I know that I'm asking a lot of help without any clue of my code. But I canno't share more information about it, I'm sorry... Will try to solve my problem with what you gave me today and will keep you updated. Thanks a lot
