我有一个名为 AddressModel 的 ListModel 和一个 Listview 来显示模型内容，Delegate 包含两个矩形组件（充当向上和向下按钮）和一个 Text 组件，我的要求是将焦点转移到单击的委托我已经list.currentIndex = index在委托中添加了行，但它不工作。请帮我解决这个问题。
这是我的 ListView.Qml 文件
import QtQuick 2.0
Rectangle {
id: idRect
width: 600 ; height: 300
Component {
id: idCompDelegate
Item {
id: idItmRow

Rectangle {
id: idRectUp

height: 50

radius: 8
Text {
anchors.centerIn: parent
text: "Up"
}
MouseArea {
id: idMouseAreaUp
anchors.fill: parent
propagateComposedEvents: true
onClicked: {
list.currentIndex = index //it's not working
((list.currentIndex)===0) ? console.log("Cannot Move towards Up"):list.model.move(list.currentIndex,list.currentIndex-1,1)
}
}
}
Text {
id: idCenterText

(list.count === (list.currentIndex)+1)? console.log("Cannot Move towards Down"):list.model.move(list.currentIndex,list.currentIndex+1,1)
}
}
}
}
}
}
