Aside from the normal desktop shell for Wayland's Weston reference compositor, open-source Intel developers have resurrected work on a tablet-oriented shell for this fledging display server.
Juan Zhao wrote on Friday to the Wayland developers about
bringing tablet-shell back to life. The Intel OTC developers have added sliding support to this Wayland tablet shell built around the Weston compositor plus simple-egl and toytoolkit applications. The tablet shell handles applications different in terms of full-screen support or otherwise blacking out the surface around the centered application.
Developers are still working on improving the Wayland tablet experience and are currently soliciting for feedback.
The code for the weston-tablet-shell can currently be found on
Gitorious. Those wanting to see this new shell in action can find a short video recorded by Intel via
this Google Docs page.
