From: Rafael Antognolli <[email protected]> Hello all,
After some discussions about how to add some features to the wl_shell protocol and how it would possibly break existing behavior, the idea of a xdg_shell protocol appeared, similar to what ewmh is to X11. It would be a shell interface defined by features needed by the desktop shells that would implement a Wayland compositor, with the needs defined by the toolkits implementing a Wayland backend. This shell protocol will not be part of the Wayland core protocol, thus it can keep being developed and have its API changed until we reach a point where it is good enough from the point of view of more than only one compositor. The following patch only adds the xdg_shell.xml as a copy of the original wl_shell protocol, but keep in mind that it will be changed and have its API broken. It also only installs the .xml file, but does not necessarily generate the headers and lib using wayland_scanner. The idea would be to generate these from the compositor and toolkit implementing such API, but I wasn't able to use wayland_scanner to generate the code from more than one path. It means that we would have to copy the xdg_shell.xml just like what is done with some other protocol extensions. Please let me know if there's a way to use it directly from its installation path. Neil and Rob, please add any comments if possible. I don't know if I was clear enough about the intention of this change. At least in the beginning, the xdg_shell would have some surface types removed, in favor of adding surface states, and the transient surface type would possibly be changed too. There's still a discussion if this would be a minimal common denominator that all desktop shells would implement, with additional features being added to <another_desktop>_shell.xml, or if it would be a set of features that some desktop shells could not necessarily implement. Thanks for any comments.
