在Qt Qml控件，ApplicationWindow缺乏本机主题运行时

问题描述

Qml控件在默认情况下提供了一个很好的类似native的主题。当我通过解释器运行我的程序作为qml文件，它看起来不错，但是，一旦我复制我的代码到c + +后端和构建它，它看起来完全没有温柔和非常平淡。此外，我没有启用任何类型的控制样式，以使原生的主题无效。

Qml Controls comes with a nice native-like theme by default. When I run my program as qml files through the interpreter, it looks great, however, once I copy my code over to c++ backend and build it, it looks completely unthemed and very bland. Also I did not enable any sort of Control Styles to void the native looking theme.

我改变的唯一的事情是，因为我的根对象在我的主qml文件是一个ApplicationWindow，我改变了main.cpp文件从加载qmlviewer，到创建我自己的应用程序引擎。我认为这可能是问题，但我不确定。

The only thing that I changed was since my root object in my main qml file is a ApplicationWindow, I changed the main.cpp file from loading qmlviewer, to creating my own application engine. I was thinking that this might be the issue but i'm not sure.

#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QQuickWindow>

int main(int argc, char *argv[]) {
    QGuiApplication app(argc, argv);
    QQmlApplicationEngine engine;

    engine.load(QUrl("src/qml/main.qml"));
    QObject *topLevel = engine.rootObjects().value(0);
    QQuickWindow *window = qobject_cast<QQuickWindow *>(topLevel);

    window->show();
    return app.exec();
}
