Detailed Description

       data transfer interface

       The wl_data_device_manager is a singleton global object that provides access to inter-
       client data transfer mechanisms such as copy-and-paste and drag-and-drop. These mechanisms
       are tied to a wl_seat and this interface lets a client get a wl_data_device corresponding
       to a wl_seat.

       Depending on the version bound, the objects created from the bound wl_data_device_manager
       object will have different requirements for functioning properly. See
       wl_data_source.set_actions, wl_data_offer.accept and wl_data_offer.finish for details.

   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(data_source_t)> & data_device_manager_t::on_create_data_source ()
       create a new data source

       Parameters
           id data source to create

       Create a new data source.

       Definition at line 2169 of file wayland-server-protocol.cpp.

   std::function< void(data_device_t, seat_t)> & data_device_manager_t::on_get_data_device ()
       create a new data device

       Parameters
           id data device to create
           seat seat associated with the data device

       Create a new data device for a given seat.

       Definition at line 2175 of file wayland-server-protocol.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
