Binding loops sucks, but with some refactoring we always get to an alternative.
Try this:
Rectangle {
width: parent.width
height: label.paintedHeight*2
Text {
id: label
text: “title
anchors.centerIn: parent
}
}
If the binding loops persists maybe the dependency is being caused by
anchors.centerIn: parent
