Scroll_Bar 아이템 사용

ListView {
    id: list;
 
    anchors.fill: parent;
 
    model: 100;
 
    delegate: Rectangle {
        height: 95;
        width: parent.width;
        color: (model.index %2 === 0 ? "darkgray" : "lightgreen");
    }
}
 
 
Rectangle{
    x: 1257 - 276
    y: 199 - 165
 
    Scroll_Bar {

        flickable: list;
    }
}
