Hi and welcome to devnet,

What about using Qt3D ?

@SGaist Oh, sorry, I previously mistakenly believe that QOpenGLWidget belongs to Qt:3D module。

Now I have already seen 3 examples：
qt3d-basicshapes-cpp-example
qt3d-materials-cpp-example
qt3d-simple-cpp-example

1. Is like this to embedded 3D windows to app ?，Is this the only way？:

    Qt3DExtras::Qt3DWindow view;

    // Scene Root
    Qt3DCore::QEntity *sceneRoot = new Qt3DCore::QEntity();
    ...
    RenderableEntity *chest = new RenderableEntity(sceneRoot);
    chest->transform()->setScale(0.03f);
    // load obj file
    chest->mesh()->setSource(QUrl(QStringLiteral("qrc:/assets/chest/Chest.obj")));
    ...
    view.setRootEntity(sceneRoot);
    view.show();

2. And if i use Qt:3D ，how can i control a 3D model(*.obj) using a QTimer，because I need to use a timer to control the gesture of the 3D model in my project，including mouse event, key event and repaint, resize etc.

how to do control it using Qt:3D，is there a reference example?

You should start here. You can find there amongst other things the Input and Animation module that will likely contain what you are looking for.
