Override onPropertyChanged in inherited

dextermagnific

Hi all,

I have a specialized SpinBox in a .qml in which I implemented a default onValueModified:

# MySpinBox.qml

SpinBox {
...
  onValueModified: { print("modified in Base") }
}

Now I use this in my QML:

MySpinBox  {
  onValueModified: { print("modified in inherited") }
}

My problem is that I get the two messages printed. I thought that "on property changed" will be overriden in the inherited class. This happens like this for functions.

How can I manage so that only the code in the inherited implementation will be executed ?

Thank you

Can you please tell me why you want to call valueModified() signal from SpinBox { } when you can directly use it from MySpinBox { } ?

To avoid your problem you can define your own signal and use it.

MySpinBox.qml

SpinBox {
    id: root
    
    signal valueChanged()

    onValueModified: {
        root.valueChanged();
    }
}

And in main.qml just use onValueChanged

    MySpinBox {

        onValueChanged: {
            console.log("Value :: ", value)
        }
    }
