TpAccountChannelRequestTpAccountChannelRequest — Object used to request a channel from a TpAccount |
TpAccount * | account | Read / Write / Construct Only |

GVariant * | request | Read / Write / Construct Only |
gint64 | user-action-time | Read / Write / Construct Only |
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.
TpAccountChannelRequest * tp_account_channel_request_new (TpAccount *account
,GVariant *request
,gint64 user_action_time
);
Convenience function to create a new TpAccountChannelRequest object.
If request
is a floating reference, this function will
take ownership of it, much like g_variant_ref_sink()
. See documentation of
that function for details.

void tp_account_channel_request_set_request_property (TpAccountChannelRequest *self
,const gchar *name
,GVariant *value
);
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:
1 2 3 4 |
tp_account_channel_request_set_request_property (acr, "com.example.Int", g_variant_new_int32 (17)); tp_account_channel_request_set_request_property (acr, "com.example.String", g_variant_new_string ("ferret")); |
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.
Since 0.19.0
TpAccountChannelRequest * tp_account_channel_request_new_text (TpAccount *account
,gint64 user_action_time
);
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:
tp_account_channel_request_set_target_contact()
tp_account_channel_request_set_target_id()

);
If is_sms_channel
is set to TRUE, messages sent and received on the
requested channel will be transmitted via SMS.
This function can't be called once self
has been used to request a
channel.
Since 0.23.2
TpAccountChannelRequest * tp_account_channel_request_new_audio_call (TpAccount *account
,gint64 user_action_time
);
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:
tp_account_channel_request_set_target_contact()
tp_account_channel_request_set_target_id()
To call a contact, either use
tp_account_channel_request_set_target_contact()
or one of the generic
methods that takes a entity type argument. To check whether this
is possible, use tp_capabilities_supports_audio_call()
with
entity_type
set to TP_ENTITY_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 entity_type
set to
TP_ENTITY_TYPE_NONE
.

TpAccountChannelRequest * tp_account_channel_request_new_audio_video_call (TpAccount *account
,gint64 user_action_time
);
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.

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:
tp_account_channel_request_set_target_contact()
tp_account_channel_request_set_target_id()

void tp_account_channel_request_set_file_transfer_description (TpAccountChannelRequest *self
,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.
Since 0.19.0
void tp_account_channel_request_set_file_transfer_initial_offset (TpAccountChannelRequest *self
,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.
Since 0.19.0
void tp_account_channel_request_set_file_transfer_timestamp (TpAccountChannelRequest *self
,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.

Since 0.19.0
void tp_account_channel_request_set_file_transfer_uri (TpAccountChannelRequest *self
,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
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.

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.

still exists. Instead of creating a new channel, the channel dispatcher
notifies the existing handler of channel
