我尝试使用 QML ProgressBar。这是文档 https://doc.qt.io/qt-5/qml-qtquick-controls-styles-progressbarstyle.html#details

我尝试这段代码

import QtQuick 2.14
import QtQuick.Controls 2.15
import QtQuick.Window 2.14
import QtQuick.Controls.Styles 1.4

Window {
    id: root
    width: 300; height: 300

    ProgressBar {
        value: 0.5
        style: ProgressBarStyle {
            background: Rectangle {
                radius: 2
                color: "lightgray"
                border.color: "gray"
                border.width: 1
                implicitWidth: 200
                implicitHeight: 24
            }
            progress: Rectangle {
                color: "lightsteelblue"
                border.color: "steelblue"
            }
        }
    }
}

但我有错误invalid property name "style"。我做错了什么？
