Detailed Description

       displays a single surface per output

       Displays a single surface per output.

       This interface provides a mechanism for a single client to display simple full-screen
       surfaces. While there technically may be multiple clients bound to this interface, only
       one of those clients should be shown at a time.

       To present a surface, the client uses either the present_surface or
       present_surface_for_mode requests. Presenting a surface takes effect on the next
       wl_surface.commit. See the individual requests for details about scaling and mode
       switches.

       The client can have at most one surface per output at any time. Requesting a surface to be
       presented on an output that already has a surface replaces the previously presented
       surface. Presenting a null surface removes its content and effectively disables the
       output. Exactly what happens when an output is 'disabled' is compositor-specific. The same
       surface may be presented on multiple outputs simultaneously.

       Once a surface is presented on an output, it stays on that output until either the client
       removes it or the compositor destroys the output. This way, the client can update the
       output's contents by simply attaching a new buffer.

       Warning! The protocol described in this file is experimental and backward incompatible
       changes may be made. Backward compatible changes may be added together with the
       corresponding interface version bump. Backward incompatible changes are done by bumping
       the version number in the protocol and interface names and resetting the interface
       version. Once the protocol is to be declared stable, the 'z' prefix and the version number
       in the protocol and interface names are removed and the interface version number is reset.

Member Enumeration Documentation

   enum class wayland::proxy_t::wrapper_type [strong],  [inherited]
       Underlying wl_proxy type and properties of a proxy_t that affect construction,
       destruction, and event handling

       Enumerator

       standard
              C pointer is a standard type compatible with wl_proxy*. Events are dispatched and
              it is destructed when the proxy_t is destructed. User data is set.

       display
              C pointer is a wl_display*. No events are dispatched, wl_display_disconnect is
              called when the proxy_t is destructed. User data is set.

       foreign
              C pointer is a standard type compatible with wl_proxy*, but another library owns it
              and it should not be touched in a way that could affect the operation of the other
              library. No events are dispatched, wl_proxy_destroy is not called when the proxy_t
              is destructed, user data is not touched. Consequently, there is no reference
              counting for the proxy_t. Lifetime of such wrappers should preferably be short to
              minimize the chance that the owning library decides to destroy the wl_proxy.

       proxy_wrapper
              C pointer is a wl_proxy* that was constructed with wl_proxy_create_wrapper. No
              events are dispatched, wl_proxy_wrapper_destroy is called when the proxy_t is
              destroyed. Reference counting is active. A reference to the proxy_t creating this
              proxy wrapper is held to extend its lifetime until after the proxy wrapper is
              destroyed.

Member Function Documentation

   wl_proxy * wayland::proxy_t::c_ptr () const [inherited]
       Get a pointer to the underlying C struct.

       Returns
           The underlying wl_proxy wrapped by this proxy_t if it exists, otherwise an exception
           is thrown

   std::string wayland::proxy_t::get_class () const [inherited]
       Get the interface name (class) of a proxy object.

       Returns
           The interface name of the object associated with the proxy

   uint32_t wayland::proxy_t::get_id () const [inherited]
       Get the id of a proxy object.

       Returns
           The id the object associated with the proxy

   uint32_t wayland::proxy_t::get_version () const [inherited]
       Get the protocol object version of a proxy object. Gets the protocol object version of a
       proxy object, or 0 if the proxy was created with unversioned API.

       A returned value of 0 means that no version information is available, so the caller must
       make safe assumptions about the object's real version.

       display_t will always return version 0.

       Returns
           The protocol object version of the proxy or 0

   wrapper_type wayland::proxy_t::get_wrapper_type () const [inline],  [inherited]
       Get the type of a proxy object.

   std::function< void(zwp_fullscreen_shell_v1_capability)> &
       zwp_fullscreen_shell_v1_t::on_capability ()
       advertises a capability of the compositor

       Parameters
           capability

       Advertises a single capability of the compositor.

       When the wl_fullscreen_shell interface is bound, this event is emitted once for each
       capability advertised. Valid capabilities are given by the wl_fullscreen_shell.capability
       enum. If clients want to take advantage of any of these capabilities, they should use a
       wl_display.sync request immediately after binding to ensure that they receive all the
       capability events.

       Definition at line 4271 of file wayland-client-protocol-unstable.cpp.

   wayland::proxy_t::operator bool () const [inherited]
       Check whether this wrapper actually wraps an object.

       Returns
           true if there is an underlying object, false if this wrapper is empty

   bool wayland::proxy_t::operator!= (const proxy_t & right) const [inherited]
       Check whether two wrappers refer to different objects.

   bool wayland::proxy_t::operator== (const proxy_t & right) const [inherited]
       Check whether two wrappers refer to the same object.

   void zwp_fullscreen_shell_v1_t::present_surface (surface_t const & surface,
       zwp_fullscreen_shell_v1_present_method const & method, output_t const & output)
       present surface for display

       Parameters
           surface
           method
           output

       Present a surface on the given output.

       If the output is null, the compositor will present the surface on whatever display (or
       displays) it thinks best. In particular, this may replace any or all surfaces currently
       presented so it should not be used in combination with placing surfaces on specific
       outputs.

       The method parameter is a hint to the compositor for how the surface is to be presented.
       In particular, it tells the compositor how to handle a size mismatch between the presented
       surface and the output. The compositor is free to ignore this parameter.

       The 'zoom', 'zoom_crop', and 'stretch' methods imply a scaling operation on the surface.
       This will override any kind of output scaling, so the buffer_scale property of the surface
       is effectively ignored.

       This request gives the surface the role of a fullscreen shell surface. If the surface
       already has another role, it raises a role protocol error.

       Definition at line 4258 of file wayland-client-protocol-unstable.cpp.

   zwp_fullscreen_shell_mode_feedback_v1_t zwp_fullscreen_shell_v1_t::present_surface_for_mode
       (surface_t const & surface, output_t const & output, int32_t framerate)
       present surface for display at a particular mode

       Parameters
           surface
           output
           framerate

       Presents a surface on the given output for a particular mode.

       If the current size of the output differs from that of the surface, the compositor will
       attempt to change the size of the output to match the surface. The result of the mode-
       switch operation will be returned via the provided wl_fullscreen_shell_mode_feedback
       object.

       If the current output mode matches the one requested or if the compositor successfully
       switches the mode to match the surface, then the mode_successful event will be sent and
       the output will contain the contents of the given surface. If the compositor cannot match
       the output size to the surface size, the mode_failed will be sent and the output will
       contain the contents of the previously presented surface (if any). If another surface is
       presented on the given output before either of these has a chance to happen, the
       present_cancelled event will be sent.

       Due to race conditions and other issues unknown to the client, no mode-switch operation is
       guaranteed to succeed. However, if the mode is one advertised by wl_output.mode or if the
       compositor advertises the ARBITRARY_MODES capability, then the client should expect that
       the mode-switch operation will usually succeed.

       If the size of the presented surface changes, the resulting output is undefined. The
       compositor may attempt to change the output mode to compensate. However, there is no
       guarantee that a suitable mode will be found and the client has no way to be notified of
       success or failure.

       The framerate parameter specifies the desired framerate for the output in mHz. The
       compositor is free to ignore this parameter. A value of 0 indicates that the client has no
       preference.

       If the value of wl_output.scale differs from wl_surface.buffer_scale, then the compositor
       may choose a mode that matches either the buffer size or the surface size. In either case,
       the surface will fill the output.

       This request gives the surface the role of a fullscreen shell surface. If the surface
       already has another role, it raises a role protocol error.

   bool wayland::proxy_t::proxy_has_object () const [inherited]
       Check whether this wrapper actually wraps an object.

       Returns
           true if there is an underlying object, false if this wrapper is empty

   void wayland::proxy_t::proxy_release () [inherited]
       Release the wrapped object (if any), making this an empty wrapper. Note that display_t
       instances cannot be released this way. Attempts to do so are ignored.

       Examples
           foreign_display.cpp.

   void zwp_fullscreen_shell_v1_t::release ()
       release the wl_fullscreen_shell interface Release the binding from the wl_fullscreen_shell
       interface.

       This destroys the server-side object and frees this binding. If the client binds to
       wl_fullscreen_shell multiple times, it may wish to free some of those bindings.

       Definition at line 4252 of file wayland-client-protocol-unstable.cpp.

   void wayland::proxy_t::set_queue (event_queue_t queue) [inherited]
       Assign a proxy to an event queue.

       Parameters
           queue The event queue that will handle this proxy

       Assign proxy to event queue. Events coming from proxy will be queued in queue instead of
       the display's main queue.

       See also: display_t::dispatch_queue().

       Examples
           proxy_wrapper.cpp.
