如何启用多重采样，当我创建的窗口？ 我应该如何初始化的OpenGL搭配？
Answer 1:
我花了一段时间才能弄清楚这一个。
诀窍是使用QSurfaceFormat在QWindow的构造就像这样：
setSurfaceType(QWindow::OpenGLSurface);
QSurfaceFormat format;
format.setSamples(4); // Set the number of samples used for multisampling
setFormat(format); // Note we set the format on the window...
create(); // Create the window
context = new QOpenGLContext(this);
context->setFormat(format); // ...and set the format on the context too
context->create();
后来，OpenGL的初始化时：
glEnable(GL_MULTISAMPLE); // This seems to be the default given the configuration above, but just in case that's not universal...
