Hi Matt yes, I want to bind a wl_surface to a subsurface first, then create a shell surface for it.
I want to do that is because if the wl surface is created by another compositor, it had been declared as a subsurface to map its position of original compositor. Then weston shell can't manage the surface as a window directly, I was just wondering how can make weston shell could manage these kind of surfaces as separate windows too. It seems create shell surface for each wl surface is not a good idea in this case. Thank you for confirmation!
