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.

- 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.

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

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
