有没有可能在QML中找到TextFiled中文本的起始和结束几何位置？

import QtQuick 2.15
import QtQuick.Controls 2.15

ApplicationWindow {
    visible: true
    width: 400
    height: 200
    title: "QML TextField Text Position Example"

    TextField {
        id: textField
        anchors.centerIn: parent
        width: parent.width * 0.8
        placeholderText: "Enter text"

        onTextChanged: {
            var metrics = textField.fontMetrics
            var startPosition = metrics.leftBearing(textField.text)
            var endPosition = metrics.width(textField.text)

            console.log("Start position: ", startPosition)
            console.log("End position: ", endPosition)
        }
    }
}
