[Solved] How can I disable Antialiasing for the Sceen Graph OpenGL Context? [Qt 5.3.1]

[Bugtracker]

I use QQuickFramebufferObject::Renderer to draw my QQuickItem with native OpenGL.
I use the OpenGL context of the Scene Graph.
So how can i disable MSAA for these context?

PS . Is the context version of the scene graph always opengl 4.2?

Problem Solved:

@QOpenGLFramebufferObject* SceneRenderer::createFramebufferObject(const QSize &size)
{
QOpenGLFramebufferObjectFormat format;
format.setAttachment(QOpenGLFramebufferObject::CombinedDepthStencil);
format.setSamples(0);
return new QOpenGLFramebufferObject(size, format);
}@
