Non-wrapping Tumbler
The default contentItem of Tumbler is a PathView, which wraps when it reaches the top and bottom. To achieve a non-wrapping Tumbler, use ListView as the contentItem:
Tumbler { id: listViewTumbler contentItem: ListView { anchors.fill: parent model: listViewTumbler.model delegate: listViewTumbler.delegate snapMode: ListView.SnapToItem highlightRangeMode: ListView.StrictlyEnforceRange preferredHighlightBegin: height / 2 - (height / listViewTumbler.visibleItemCount / 2) preferredHighlightEnd: height / 2 + (height / listViewTumbler.visibleItemCount / 2) clip: true } }
Note: Types in the Qt.labs module are not guaranteed to remain compatible in future versions.
