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     } }
