Hi Abhishek, A textured quad doesn't have any lines so won't be affected by glLineWidth/osg::LineWidth, only line primitives are affected by this bit of OpenGL state.
If you want a line outline around your quad you'll need to create an geometry with a line around it. Have a look at the osggeometry for a guide to how to create various types of geometry. Robert.
