Add interface ivi_application, which creates ivi_surface objects tied to a given wl_surface with a given id. The given id can be used in a shell to identify which application is assigned to a wl_surface and layout the surface wherever the shell wants. ivi_surface objects can be used to receive status of wl_surface in the scenegraph of the compositor.
Signed-off-by: Nobuhiko Tanibata <[email protected]> --- Changes for v2: - Rename "error" to "warning" because meaning of "error" in wayland is fatal. Changes for v3: - Move "warning" from ivi_application to ivi_surface. - Squash Makefile. - Add description to ivi_surface:destroy. - Update description of ivi_application:surface_create. protocol/Makefile.am | 3 +- protocol/ivi-application.xml | 96 ++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 98 insertions(+), 1 deletion(-) create mode 100644 protocol/ivi-application.xml diff --git a/protocol/Makefile.am b/protocol/Makefile.am index 5e331a7..9913f16 100644 --- a/protocol/Makefile.am +++ b/protocol/Makefile.am @@ -8,7 +8,8 @@ protocol_sources = \ text-cursor-position.xml \ wayland-test.xml \ xdg-shell.xml \ - scaler.xml + scaler.xml \ + ivi-application.xml if HAVE_XMLLINT .PHONY: validate diff --git a/protocol/ivi-application.xml b/protocol/ivi-application.xml new file mode 100644 index 0000000..8f5c23d --- /dev/null +++ b/protocol/ivi-application.xml @@ -0,0 +1,96 @@ +<?xml version="1.0" encoding="UTF-8"?> +<protocol name="ivi_application"> + + <copyright> + Copyright (C) 2013 DENSO CORPORATION + Copyright (c) 2013 BMW Car IT GmbH + + Permission is hereby granted, free of charge, to any person obtaining a copy + of this software and associated documentation files (the "Software"), to deal + in the Software without restriction, including without limitation the rights + to use, copy, modify, merge, publish, distribute, sublicense, and/or sell + copies of the Software, and to permit persons to whom the Software is + furnished to do so, subject to the following conditions: + + The above copyright notice and this permission notice shall be included in + all copies or substantial portions of the Software. + + THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
