Description

A TpAccountChannelRequest object is used to request a channel using the ChannelDispatcher. Once created, use one of the create or ensure async method to actually request the channel.

Note that each TpAccountChannelRequest object can only be used to create one channel. You can't call a create or ensure method more than once on the same TpAccountChannelRequest.

Once the channel has been created you can use the TpAccountChannelRequest::re-handled: signal to be notified when the channel has to be re-handled. This can be useful for example to move its window to the foreground, if applicable.

Using this object is appropriate for most channel types. For a contact search channel, use tp_contact_search_new_async() instead.

Configure this channel request to include the given property, as documented in the Telepathy D-Bus API Specification or an implementation-specific extension.

Using this method is not recommended, but it can be necessary for experimental or implementation-specific interfaces.

If the property is not supported by the protocol or channel type, the channel request will fail. Use TpCapabilities and the Telepathy D-Bus API Specification to determine which properties are available.

If value is a floating reference, this method takes ownership of it by using g_variant_ref_sink(). This allows convenient inline use of GVariant constructors:

It is an error to provide a value which contains types not supported by D-Bus.

This function can't be called once self has been used to request a channel.

self :

name :

a D-Bus property name

value :

an arbitrary value for the property

Convenience function to create a new TpAccountChannelRequest object which will yield a Text channel.

After creating the request, you will also need to set the "target" of the channel by calling one of the following functions:

account :

a TpAccount

user_action_time :

the time of the user action that caused this request, or one of the special values TP_USER_ACTION_TIME_NOT_USER_ACTION or TP_USER_ACTION_TIME_CURRENT_TIME (see "user-action-time")

Returns :

Convenience function to create a new TpAccountChannelRequest object which will yield a Call channel, initially carrying audio only.

After creating the request, you will usually also need to set the "target" of the channel by calling one of the following functions:

To call a contact, either use tp_account_channel_request_set_target_contact() or one of the generic methods that takes a handle type argument. To check whether this is possible, use tp_capabilities_supports_audio_call() with handle_type set to TP_HANDLE_TYPE_CONTACT.

In some protocols, it is possible to create a Call channel without setting a target at all, which will result in a new, empty conference call. To test whether this is possible, use tp_capabilities_supports_audio_call() with handle_type set to TP_HANDLE_TYPE_NONE.

account :

a TpAccount

user_action_time :

the time of the user action that caused this request, or one of the special values TP_USER_ACTION_TIME_NOT_USER_ACTION or TP_USER_ACTION_TIME_CURRENT_TIME (see "user-action-time")

Returns :

a new TpAccountChannelRequest object

Convenience function to create a new TpAccountChannelRequest object which will yield a Call channel, initially carrying both audio and video.

This is the same as tp_account_channel_request_new_audio_call(), except that the channel will initially carry video as well as audio, and instead of using tp_capabilities_supports_audio_call() you should test capabilities with tp_capabilities_supports_audio_video_call().

See the documentation of tp_account_channel_request_new_audio_call() for details of how to set the target (contact, chatroom etc.) for the call.

account :

a TpAccount

user_action_time :

the time of the user action that caused this request, or one of the special values TP_USER_ACTION_TIME_NOT_USER_ACTION or TP_USER_ACTION_TIME_CURRENT_TIME (see "user-action-time")

Returns :

a new TpAccountChannelRequest object

Convenience function to create a new TpAccountChannelRequest object, which will yield a FileTransfer channel to send a file to a contact.

After creating the request, you will also need to set the "target" of the channel by calling one of the following functions:

account :

a TpAccount

filename :

a suggested name for the file, which should not contain directories or directory separators (for example, if you are sending a file called /home/user/monkey.pdf, set this to monkey.pdf)

mime_type :

the MIME type (content-type) of the file; a NULL value is allowed, and is treated as "application/octet-stream". [allow-none]

size :

the file's size in bytes

user_action_time :

the time of the user action that caused this request, or one of the special values TP_USER_ACTION_TIME_NOT_USER_ACTION or TP_USER_ACTION_TIME_CURRENT_TIME (see "user-action-time")

                                                         const gchar *description);

Configure this channel request to provide the recipient of the file with the given description.

If file descriptions are not supported by the protocol, or if this method is used on a request that is not actually a file transfer, the channel request will fail. Use tp_capabilities_supports_file_transfer_description() to determine whether outgoing file transfers can have a description.

This function can't be called once self has been used to request a channel.

                                                         guint64 offset);

Configure this channel request to inform the recipient of the file that this channel will not send the first offset bytes of the file. In some protocols, this can be used to resume an interrupted transfer.

If this method is not called, the default is to start from the beginning of the file (equivalent to offset = 0).

If offsets greater than 0 are not supported by the protocol, or if this method is used on a request that is not actually a file transfer, the channel request will fail. Use tp_capabilities_supports_file_transfer_initial_offset() to determine whether offsets greater than 0 are available.

This function can't be called once self has been used to request a channel.

                                                         guint64 timestamp);

Configure this channel request to accompany the file transfer with the given modification timestamp for the file.

If file timestamps are not supported by the protocol, or if this method is used on a request that is not actually a file transfer, the channel request will fail. Use tp_capabilities_supports_file_transfer_date() to determine whether outgoing file transfers can have a timestamp.

This function can't be called once self has been used to request a channel.

self :

a TpAccountChannelRequest

timestamp :

the modification timestamp of the file, in seconds since the Unix epoch (the beginning of 1970 in the UTC time zone), as returned by g_date_time_to_unix()

                                                         const gchar *uri);

Configure this channel request to provide other local Telepathy components with the URI of the file being sent. Unlike most properties on a file transfer channel, this information is not sent to the recipient of the file; instead, it is signalled on D-Bus for use by other Telepathy components.

The URI should usually be a file URI as defined by RFC 1738 §3.10 (for instance, file:///path/to/file or file://localhost/path/to/file). If a remote resource is being transferred to a contact, it may have a different scheme, such as http.

Even if this method is used, the connection manager will not read the file from disk: the handler for the channel is still responsible for streaming the file. However, providing the URI allows a local logger to log which file was transferred, for instance.

If this functionality is not supported by the connection manager, or if this method is used on a request that is not actually a file transfer, the channel request will fail. Use tp_capabilities_supports_file_transfer_uri() to determine whether outgoing file transfers can have a URI.

This function can't be called once self has been used to request a channel.

self :

a TpAccountChannelRequest

uri :

the source URI for the file

Asynchronously calls CreateChannel on the ChannelDispatcher to create a channel with the properties defined in "request" that you are going to handle yourself. When the operation is finished, callback will be called. You can then call tp_account_channel_request_create_and_handle_channel_finish() to get the result of the operation.

(Behind the scenes, this works by creating a temporary TpBaseClient, then acting like tp_account_channel_request_create_channel_async() with the temporary TpBaseClient as the preferred_handler.)

Property Details

The "account" property

  "account"                  TpAccount*            : Read / Write / Construct Only

The TpAccount used to request the channel. Read-only except during construction.

This property can't be NULL.

Since 0.11.12


The "channel-request" property

  "channel-request"          TpChannelRequest*     : Read

The TpChannelRequest used to request the channel, or NULL if the channel has not be requested yet.

This can be useful for example to compare with the TpChannelRequest objects received from the requests_satisfied argument of TpSimpleHandlerHandleChannelsImpl to check if the client is asked to handle the channel it just requested.

Note that the TpChannelRequest objects may be different while still representing the same ChannelRequest on D-Bus. You have to compare them using their object paths (tp_proxy_get_object_path()).

Since 0.13.13


The "request" property

  "request"                  GHashTable_gchararray+GValue_*  : Read / Write / Construct Only

The desired D-Bus properties for the channel, represented as a GHashTable where the keys are strings and the values are GValue.

When constructing a new object, one of "request" or "request-vardict" must be set to a non-NULL value, and the other must remain unspecified.

Since 0.11.12


The "request-vardict" property

  "request-vardict"          GVariant*             : Read / Write / Construct Only

The desired D-Bus properties for the channel.

When constructing a new object, one of "request" or "request-vardict" must be set to a non-NULL value, and the other must remain unspecified.

Allowed values: GVariant<a{sv}>

Default value: NULL

Since 0.19.10


The "user-action-time" property

  "user-action-time"         gint64                : Read / Write / Construct Only

The user action time that will be passed to the channel dispatcher when requesting the channel.

This may be the time at which user action occurred, or one of the special values TP_USER_ACTION_TIME_NOT_USER_ACTION or TP_USER_ACTION_TIME_CURRENT_TIME.

If TP_USER_ACTION_TIME_NOT_USER_ACTION, the action doesn't involve any user action. Clients should avoid stealing focus when presenting the channel.

If TP_USER_ACTION_TIME_CURRENT_TIME, clients SHOULD behave as though the user action happened at the current time, e.g. a client may request that its window gains focus.

On X11-based systems, GDK 2, GDK 3, Clutter 1.0 etc., tp_user_action_time_from_x11() can be used to convert an X11 timestamp to a Telepathy user action time.

If the channel request succeeds, this user action time will be passed on to the channel's handler. If the handler is a GUI, it may use tp_user_action_time_should_present() to decide whether to bring its window to the foreground.

Default value: 0

Since 0.11.12

Emitted when the channel created using self has been "re-handled".

This means that a Telepathy client has made another request for a matching channel using an "ensure" API like tp_account_channel_request_ensure_channel_async(), while the channel still exists. Instead of creating a new channel, the channel dispatcher notifies the existing handler of channel, resulting in this signal.

Most GUI handlers should respond to this signal by checking user_action_time, and if appropriate, moving to the foreground.

context can be used to obtain extensible information about the channel via tp_handle_channels_context_get_handler_info(), and any similar methods that are added in future. It is not valid for the receiver of this signal to call tp_handle_channels_context_accept(), tp_handle_channels_context_delay() or tp_handle_channels_context_fail().

self :

a TpAccountChannelRequest

channel :

the TpChannel being re-handled

user_action_time :

the time at which user action occurred, or one of the special values TP_USER_ACTION_TIME_NOT_USER_ACTION or TP_USER_ACTION_TIME_CURRENT_TIME; see "user-action-time"

context :

a TpHandleChannelsContext representing the context of the HandleChannels() call.

user_data :

user data set when the signal handler was connected.
