[Interest] How to combine glLineWidth call with Qt3D in QML?

Hi, Guys,
I am evaluating Qt3D with a new project. I wrote a customised Qt3D object for loading and displaying triangle mesh lines in 3d scene and wondering where I can put in glLineWidth to change the line width.
What I am doing is inheriting from Qt3D::QAbstractMesh, and providing a Qt3D::QAbstractMeshFunctorPtr to return Qt3D::QMeshData constructed with Qt3D::QMeshData::Lines.
I can’t find anywhere I can specify the line width in any Qt3D QML objects.
I know I can achieve that by shaders but I think using glLineWidth is a simpler way to do it.
Does Qt3D allow me to specify any OpenGL function calls during rendering for a particular object?
Thanks very much!
