Qt 5.4/Qml: Prevent binding loop

Question

I have a global singleton \"Settings\" which holds application settings. When I try to run the following code I get a QML CheckBox: Binding loop detected for property \"ch

Answer 1

If you don't want to make a binding loop - don't make a binding, use a proxy variable, for example. Other simple solution can be to check the value:

CheckBox {
    checked: Settings.someSetting                         
    onCheckedChanged: {
        if (checked !== Settings.someSetting) {
            Settings.someSetting = checked;
        }
    }
}
