Description
qmllint wrongfully complains about the tumbler attached property on the example from the documentation at https://doc.qt.io/qt-6/qml-qtquick-controls-tumbler.html:
import QtQuick import QtQuick.Controls Rectangle { // modified from the Tumbler documentation at https://doc.qt.io/qt-6/qml-qtquick-controls-tumbler.html Component { id: delegateComponent Label { text: formatText(Tumbler.tumbler.count, modelData) opacity: 1.0 - Math.abs(Tumbler.displacement) / (Tumbler.tumbler.visibleItemCount / 2) horizontalAlignment: Text.AlignHCenter verticalAlignment: Text.AlignVCenter } } }
with following warnings:
Warning: /Users/sami/tmp/untitled69/Main.qml:23:34: Tumbler: attached properties of Tumbler must be accessed through a delegate item [Quick.attached-property-type]
text: formatText(Tumbler.tumbler.count, modelData)

import QtQuick
Note that replacing the Rectangle above with a Tumbler does not make the warning go away, despite the attached property being inside a Tumbler delegate:
Tumbler {
delegate: Component {
id: delegateComponent
Label {
text: formatText(Tumbler.tumbler.count, modelData)
opacity: 1.0 - Math.abs(Tumbler.displacement) / (Tumbler.tumbler.visibleItemCount / 2)
horizontalAlignment: Text.AlignHCenter
verticalAlignment: Text.AlignVCenter
font.pixelSize: fontMetrics.font.pixelSize * 1.25
}
}
}
