Detailed Description

       receive relative pointer motion events

       The wp_locked_pointer interface represents a locked pointer state.

       While the lock of this object is active, the wl_pointer objects of the associated seat
       will not emit any wl_pointer.motion events.

       This object will send the event 'locked' when the lock is activated. Whenever the lock is
       activated, it is guaranteed that the locked surface will already have received pointer
       focus and that the pointer will be within the region passed to the request creating this
       object.

       To unlock the pointer, send the destroy request. This will also destroy the
       wp_locked_pointer object.

       If the compositor decides to unlock the pointer the unlocked event is sent. See
       wp_locked_pointer.unlock for details.

       When unlocking, the compositor may warp the cursor position to the set cursor position
       hint. If it does, it will not result in any relative motion events emitted via
       wp_relative_pointer.

       If the surface the lock was requested on is destroyed and the lock is not yet activated,
       the wp_locked_pointer object is now defunct and must be destroyed.

Member Function Documentation

   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.

   void zwp_locked_pointer_v1_t::locked (bool post = true)
       lock activation event Notification that the pointer lock of the seat's pointer is
       activated.

       Definition at line 5450 of file wayland-server-protocol-unstable.cpp.

   std::function< void()> & zwp_locked_pointer_v1_t::on_destroy ()
       destroy the locked pointer object Destroy the locked pointer object. If applicable, the
       compositor will unlock the pointer.

       Definition at line 5432 of file wayland-server-protocol-unstable.cpp.

   std::function< void(double, double)> & zwp_locked_pointer_v1_t::on_set_cursor_position_hint ()
       set the pointer cursor position hint

       Parameters
           surface_x surface-local x coordinate
           surface_y surface-local y coordinate

       Set the cursor position hint relative to the top left corner of the surface.

       If the client is drawing its own cursor, it should update the position hint to the
       position of its own cursor. A compositor may use this information to warp the pointer upon
       unlock in order to avoid pointer jumps.

       The cursor position hint is double buffered. The new hint will only take effect when the
       associated surface gets it pending state applied. See wl_surface.commit for details.

       Definition at line 5438 of file wayland-server-protocol-unstable.cpp.

   std::function< void(region_t)> & zwp_locked_pointer_v1_t::on_set_region ()
       set a new lock region

       Parameters
           region region of surface

       Set a new region used to lock the pointer.

       The new lock region is double-buffered. The new lock region will only take effect when the
       associated surface gets its pending state applied. See wl_surface.commit for details.

       For details about the lock region, see wp_locked_pointer.

       Definition at line 5444 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

   void zwp_locked_pointer_v1_t::unlocked (bool post = true)
       lock deactivation event Notification that the pointer lock of the seat's pointer is no
       longer active. If this is a oneshot pointer lock (see wp_pointer_constraints.lifetime)
       this object is now defunct and should be destroyed. If this is a persistent pointer lock
       (see wp_pointer_constraints.lifetime) this pointer lock may again reactivate in the
       future.
