有没有办法给占位符文本QML中的特定单词上色？

import QtQuick 2.0

Item {
    width: 200
    height: 200

    Text {
        width: parent.width
        height: parent.height
        text: "Hello World! This is a sample text."
        wrapMode: Text.WordWrap

        function colorText(text, color) {
            var regex = /(\b\w+\b)/g; // 正则表达式匹配单词
            var formattedText = text.replace(regex, "<font color='" + color + "'>$1</font>");
            return formattedText;
        }

        Component.onCompleted: {
            var coloredText = colorText(text, "red"); // 将特定单词上色为红色
            text = coloredText;
        }
    }
}
