成员函数文档
[explicit] QQmlAspectEngine::QQmlAspectEngine(QObject *parent = nullptr)
用parent 构建一个新的 QQmlAspectEngine。
Qt3DCore::QAspectEngine *QQmlAspectEngine::aspectEngine() const
返回 aspectEngine。
QQmlEngine *QQmlAspectEngine::qmlEngine() const
返回发动机。
[signal] void QQmlAspectEngine::sceneCreated(QObject *rootObject)
当场景被实例化后，rootObject 。这样就可以在将场景传递给方面引擎之前对其进行操作。方便窗口类在框架图上设置摄像机和曲面，以及为输入方面等设置事件源。
void QQmlAspectEngine::setSource(const QUrl &source)
将source 设置为要创建的 QML 组件的源。
Qt3DCore::Quick::QQmlAspectEngine::Status QQmlAspectEngine::status() const
返回状态。
[signal] void QQmlAspectEngine::statusChanged(Qt3DCore::Quick::QQmlAspectEngine::Status status)
当发动机状态发生变化时，该信号会通过status 发送。
