wl-proxy 0.1.2

//! 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.
