Detailed Description

       a hold gesture object

       A hold gesture object notifies a client about a single- or multi-finger hold gesture
       detected on an indirect input device such as a touchpad. The gesture is usually initiated
       by one or more fingers being held down without significant movement. The precise
       conditions of when such a gesture is detected are implementation-dependent.

       In particular, this gesture may be used to cancel kinetic scrolling.

       A hold gesture consists of two stages: begin and end. Unlike pinch and swipe there is no
       update stage. There cannot be multiple simultaneous hold, pinch or swipe gestures on a
       same pointer/seat, how compositors prevent these situations is implementation-dependent.

       A gesture may be cancelled by the compositor or the hardware. Clients should not consider
       performing permanent or irreversible actions until the end of a gesture has been received.

   void zwp_pointer_gesture_hold_v1_t::begin (uint32_t serial, uint32_t time, surface_t const &
       surface, uint32_t fingers, bool post = true)
       multi-finger hold begin

       Parameters
           serial
           time timestamp with millisecond granularity
           surface
           fingers number of fingers

       This event is sent when a hold gesture is detected on the device.

       Definition at line 5727 of file wayland-server-protocol-unstable.cpp.

   bool zwp_pointer_gesture_hold_v1_t::can_begin () const
       Check whether the begin function is available with the currently bound version of the
       protocol.

       Definition at line 5732 of file wayland-server-protocol-unstable.cpp.

   bool zwp_pointer_gesture_hold_v1_t::can_end () const
       Check whether the end function is available with the currently bound version of the
       protocol.

       Definition at line 5742 of file wayland-server-protocol-unstable.cpp.

   void zwp_pointer_gesture_hold_v1_t::end (uint32_t serial, uint32_t time, int32_t cancelled,
       bool post = true)
       multi-finger hold end

       Parameters
           serial
           time timestamp with millisecond granularity
           cancelled 1 if the gesture was cancelled, 0 otherwise

       This event is sent when a hold gesture ceases to be valid. This may happen when the
       holding fingers are lifted or the gesture is cancelled, for example if the fingers move
       past an implementation-defined threshold, the finger count changes or the hold gesture
       changes into a different type of gesture.

       When a gesture is cancelled, the client may need to undo state changes caused by this
       gesture. What causes a gesture to be cancelled is implementation-dependent.

   std::string wayland::server::resource_t::get_class () [inherited]
       Retrieve the interface name (class) of a resource object.

       Returns
           Interface name of the resource object.

   client_t wayland::server::resource_t::get_client () const [inherited]
       Get the associated client

       Returns
           the client that owns the resource.

   uint32_t wayland::server::resource_t::get_id () const [inherited]
       Get the internal ID of the resource

       Returns
           the internal ID of the resource

   unsigned int wayland::server::resource_t::get_version () const [inherited]
       Get interface version

       Returns
           Interface version this resource has been constructed with.

   std::function< void()> & zwp_pointer_gesture_hold_v1_t::on_destroy ()
       destroy the hold gesture object

       Definition at line 5721 of file wayland-server-protocol-unstable.cpp.

   void wayland::server::resource_t::post_no_memory () const [inherited]
       Post 'not enough memory' error to the client

       If the compositor has not enough memory to fulfill a certail request of the client, this
       function can be called to notify the client of this circumstance.

   bool wayland::server::resource_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
