Ok, here is what I found, it seems that using bindings in QML, values
are transfered to child components but when changed inside child the
value is not sent back to the parent:
//Parent.qml
Rectangle{
property string title: "initial value"
id: root
Child{
title: root.title
}
}
//Child.qml
Rectangle{
property string title
id:child
...
//JS script
{
child.title = "Child modified value";
// I expected this to reflect back in parent or
// whatever component was bound to it
}
...
}
Is this normal? Is there a workaround
Regards,
Cristi
