Coding QML where properties like 'parent.horizontalCenter' are not being auto-completed in my QtCreator

The auto-completed Can`t give me parent.horizontalCenter or bottom When I write "parent.hor" or "parent.bot" but other parameter can show such as height,width.

my Qt version is 6.7.1 which compile with msvc2022-pe-64bit,QtCreator version is 10.0.2

import QtQuickimport QtQuick.WindowWindow {    width: 640    height: 480    visible: true    title: qsTr("Hello World")    Image {        anchors.fill: parent        id: backgroud        source: "./images/background.png"    }    Image {        anchors.bottom: parent.bottom        anchors.horizontalCenter: parent.horizontalCenter        id: pole        source: "./images/pole.png"    }}

I tried import QtQuick.Layout but it not work
