Qml PathView 要怎么限制显示的范围

我想让图片只显示在黄框里，黄框外的不显示，要怎么弄？试过 ListView 也有同样的问题

PathView { id: _pathView x: 490 y: 260 width: 300 height: 200 snapMode: PathView.SnapOneItem model: _model delegate: _delegate pathItemCount: 5 path: _horizontalPath Path { id: _horizontalPath startX: -_pathView.currentItem.width / 2 * 3 startY: _pathView.currentItem.height / 2 PathLine { relativeX: _pathView.currentItem.width * _pathView.pathItemCount relativeY: _pathView.currentItem.y } }
