43 * @short_description: an object representing a File Transfer
44 * @include: libempathy/empathy-ft-handler
46 * #EmpathyFTHandler is the object which represents a File Transfer with all
48 * The creation of an #EmpathyFTHandler is done with
49 * empathy_ft_handler_new_outgoing() or empathy_ft_handler_new_incoming(),
50 * even though clients should not need to call them directly, as
51 * #EmpathyFTFactory does it for them. Remember that for the file transfer
52 * to work with an incoming handler,
53 * empathy_ft_handler_incoming_set_destination() should be called after
54 * empathy_ft_handler_new_incoming(). #EmpathyFTFactory does this
56 * It's important to note that, as the creation of the handlers is async, once
57 * an handler is created, it already has all the interesting properties set,
58 * like filename, total bytes, content type and so on, making it useful
59 * to be displayed in an UI.
60 * The transfer API works like a state machine; it has three signals,
61 * ::transfer-started, ::transfer-progress, ::transfer-done, which will be
62 * emitted in the relevant phases.
63 * In addition, if the handler is created with checksumming enabled,
64 * other three signals (::hashing-started, ::hashing-progress, ::hashing-done)
65 * will be emitted before or after the transfer, depending on the direction
66 * (respectively outgoing and incoming) of the handler.
67 * At any time between the call to empathy_ft_handler_start_transfer() and
68 * the last signal, a ::transfer-error can be emitted, indicating that an
69 * error has happened in the operation. The message of the error is localized
