【问题描述】：

我是 Qt/QML 编程的新手，正在尝试让以下示例在移动设备上正常运行。当我尝试“向右滑动”然后点击删除按钮时，不会删除“Listview-item”。在桌面上一切正常，但在移动设备上它不能正常工作。谁能帮我解决我的问题？

import QtQuick 2.7
import QtQuick.Controls 2.0

ApplicationWindow 
    id: appWindow
    visible: true

    ListView 
        id: listView
        anchors.fill: parent
        model: ListModel 
            ListElement  name: "Swipe Delegate - Test 1" 
            ListElement  name: "Swipe Delegate - Test 2" 
            ListElement  name: "Swipe Delegate - Test 3" 
            ListElement  name: "Swipe Delegate - Test 4" 
        
        delegate: SwipeDelegate 
            id: swipeDelegate
            text: model.name
            width: parent.width

            ListView.onRemove: SequentialAnimation 
                PropertyAction 
                    target: swipeDelegate
                    property: "ListView.delayRemove"
                    value: true
                
                NumberAnimation 
                    target: swipeDelegate
                    property: "height"
                    to: 0
                    easing.type: Easing.InOutQuad
                
                PropertyAction 
                    target: swipeDelegate;
                    property: "ListView.delayRemove";
                    value: false
                
            

            swipe.right: Label 
                id: deleteLabel
                text: qsTr("Delete")
                color: "white"
                verticalAlignment: Label.AlignVCenter
                padding: 12
                height: parent.height
                anchors.right: parent.right

                SwipeDelegate.onClicked: listView.model.remove(index)

                background: Rectangle 
                    color: deleteLabel.SwipeDelegate.pressed ? Qt.darker("tomato", 1.1) : "tomato"
                
            
        
    

【参考方案1】：

您可以在矩形内添加带有 onClicked 事件的 MouseArea。这是一个例子：

 background: Rectangle 
                color: deleteLabel.SwipeDelegate.pressed ? Qt.darker("tomato", 1.1) : "tomato"
                MouseArea 
                    anchors.fill: parent
                    onClicked: listView.model.remove(index)
