Detailed Description

       context object for input timestamps

       Provides high-resolution timestamp events for a set of subscribed input events. The set of
       subscribed input events is determined by the zwp_input_timestamps_manager_v1 request used
       to create this object.

Member Enumeration Documentation

   enum 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.

       Definition at line 301 of file wayland-client.hpp.

   std::function< void(uint32_t, uint32_t, uint32_t)> & zwp_input_timestamps_v1_t::on_timestamp
       ()
       high-resolution timestamp event

       Parameters
           tv_sec_hi high 32 bits of the seconds part of the timestamp
           tv_sec_lo low 32 bits of the seconds part of the timestamp
           tv_nsec nanoseconds part of the timestamp

       The timestamp event is associated with the first subsequent input event carrying a
       timestamp which belongs to the set of input events this object is subscribed to.

       The timestamp provided by this event is a high-resolution version of the timestamp
       argument of the associated input event. The provided timestamp is in the same clock domain
       and is at least as accurate as the associated input event timestamp.

       The timestamp is expressed as tv_sec_hi, tv_sec_lo, tv_nsec triples, each component being
       an unsigned 32-bit value. Whole seconds are in tv_sec which is a 64-bit value combined
       from tv_sec_hi and tv_sec_lo, and the additional fractional part in tv_nsec as
       nanoseconds. Hence, for valid timestamps tv_nsec must be in [0, 999999999].

   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.

   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.

   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().
