Unsolved Using "parent->findChild<QObject*>("objectName")"function,return null,when I find a ItemDelegate QML

[Daryl_X]

ListView {
            id: listView
            objectName: "mainListView"
            currentIndex: -1
            anchors.fill: parent
            anchors.top: parent.Top
            anchors.topMargin: 0.22*parent.height

            delegate: ItemDelegate {
                id: mainItemDelegate
                objectName: "mainItemDelegate"
                width: parent.width
                anchors.horizontalCenter: parent.horizontalCenter

                Image {
                    width: 0.1*parent.width
                    height: 0.8*parent.height
                    anchors.left: parent.left
                    anchors.leftMargin: 0.1*parent.width
                    source: model.icon
                }
                Label {
                    width: 0.5*parent.width
                    height: parent.height
                    text: model.title
                    anchors.horizontalCenter: parent.horizontalCenter
                }

                highlighted: ListView.isCurrentItem
                onClicked: {
                    if (listView.currentIndex != index) {
                        listView.currentIndex = index
                        mainStackView.replace(model.source)
                        if(2==index)
                        {
                            mainMenu.drawerItemChanged(index)
//                            toolBarTop.visible = fasle
                        }
                    }
                    mainDrawer.close()
                }
            }

This is my code in QML.
