Detailed Description

       an exported surface handle

       An xdg_exported object represents an exported reference to a surface. The exported surface
       may be referenced as long as the xdg_exported object not destroyed. Destroying the
       xdg_exported invalidates any relationship the importer may have established using
       xdg_imported.

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 zxdg_exported_v2_t::handle (std::string const & handle, bool post = true)
       the exported surface handle

       Parameters
           handle the exported surface handle

       The handle event contains the unique handle of this exported surface reference. It may be
       shared with any client, which then can use it to import the surface by calling
       xdg_importer.import_toplevel. A handle may be used to import the surface multiple times.

   std::function< void()> & zxdg_exported_v2_t::on_destroy ()
       unexport the exported surface Revoke the previously exported surface. This invalidates any
       relationship the importer may have set up using the xdg_imported created given the handle
       sent via xdg_exported.handle.

       Definition at line 7968 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
