Implemented Interfaces

TpChannel implements TpChannelIface.

Includes

#include <telepathy-glib/channel.h>

Description

TpChannel objects provide convenient access to Telepathy channels.

Compared with a simple proxy for method calls, they add the following features:

  • calling GetChannelType(), GetInterfaces(), GetHandles() automatically

This section also documents the auto-generated C wrappers for the Channel D-Bus interface. Of these, in general, only tp_cli_channel_call_close() and tp_cli_channel_run_close() are useful (the TpChannel object provides a more convenient API for the rest).

Functions

tp_channel_new ()

TpChannel *
tp_channel_new (TpConnection *conn,
                const gchar *object_path,
                const gchar *optional_channel_type,
                TpHandleType optional_handle_type,
                TpHandle optional_handle,
                GError **error);

tp_channel_new is deprecated and should not be used in newly-written code.

Use tp_simple_client_factory_ensure_channel() instead.

Parameters

conn

a connection; may not be NULL

 

object_path

the object path of the channel; may not be NULL

 

optional_channel_type

the channel type if already known, or NULL if not

 

optional_handle_type

the handle type if already known, or TP_UNKNOWN_HANDLE_TYPE if not

 

optional_handle

the handle if already known, or 0 if not (if optional_handle_type is TP_UNKNOWN_HANDLE_TYPE or TP_HANDLE_TYPE_NONE, this must be 0)

 

error

used to indicate the error if NULL is returned

 

Returns

a new channel proxy, or NULL on invalid arguments.

Since: 0.7.1


tp_channel_new_from_properties ()

TpChannel *
tp_channel_new_from_properties (TpConnection *conn,
                                const gchar *object_path,
                                const GHashTable *immutable_properties,
                                GError **error);

tp_channel_new_from_properties is deprecated and should not be used in newly-written code.

Use tp_simple_client_factory_ensure_channel() instead.

Parameters

conn

a connection; may not be NULL

 

object_path

the object path of the channel; may not be NULL

 

immutable_properties

the immutable properties of the channel, as signalled by the NewChannel D-Bus signal or returned by the CreateChannel and EnsureChannel D-Bus methods: a mapping from strings (D-Bus interface name + "." + property name) to GValue instances.

[transfer none][element-type utf8 GObject.Value]

error

used to indicate the error if NULL is returned

 

Returns

a new channel proxy, or NULL on invalid arguments

Since: 0.7.19


tp_channel_run_until_ready ()

gboolean
tp_channel_run_until_ready (TpChannel *self,
                            GError **error,
                            GMainLoop **loop);

tp_channel_run_until_ready has been deprecated since version 0.11.0 and should not be used in newly-written code.

Use tp_proxy_prepare_async() and re-enter the main loop yourself, or restructure your program in such a way as to avoid re-entering the main loop.

If self is ready for use (introspection has finished, etc.), return immediately. Otherwise, re-enter the main loop until the channel either becomes invalid or becomes ready for use, or until the main loop stored via loop is cancelled.

[skip]

Parameters

self

a channel

 

error

if not NULL and FALSE is returned, used to raise an error

 

loop

if not NULL, a GMainLoop is placed here while it is being run (so calling code can call g_main_loop_quit() to abort), and NULL is placed here after the loop has been run

 

Returns

TRUE if the channel has been introspected and is ready for use, FALSE if the channel has become invalid.

Since: 0.7.1


TpChannelWhenReadyCb ()

void
(*TpChannelWhenReadyCb) (TpChannel *channel,
                         const GError *error,
                         gpointer user_data);

TpChannelWhenReadyCb has been deprecated since version 0.17.6 and should not be used in newly-written code.

Signature of a callback passed to tp_channel_call_when_ready(), which will be called exactly once, when the channel becomes ready or invalid (whichever happens first)

Parameters

channel

the channel (which may be in the middle of being disposed, if error is non-NULL, error->domain is TP_DBUS_ERRORS and error->code is TP_DBUS_ERROR_PROXY_UNREFERENCED)

 

error

NULL if the channel is ready for use, or the error with which it was invalidated if it is now invalid

 

user_data

whatever was passed to tp_channel_call_when_ready()

 

tp_channel_call_when_ready ()

void
tp_channel_call_when_ready (TpChannel *self,
                            TpChannelWhenReadyCb callback,
                            gpointer user_data);

tp_channel_call_when_ready has been deprecated since version 0.17.6 and should not be used in newly-written code.

Use tp_proxy_prepare_async()

If self is ready for use or has been invalidated, call callback immediately, then return. Otherwise, arrange for callback to be called when self either becomes ready for use or becomes invalid.

This is a less general form of tp_proxy_prepare_async(), which should be used in new code. (One important difference is that this function can call callback before it has returned, whereas tp_proxy_prepare_async() always calls callback from the main loop.)

[skip]

Parameters

self

a channel

 

callback

called when the channel becomes ready or invalidated, whichever happens first

 

user_data

arbitrary user-supplied data passed to the callback

 

Since: 0.7.7


tp_channel_init_known_interfaces ()

void
tp_channel_init_known_interfaces (void);

Ensure that the known interfaces for TpChannel have been set up. This is done automatically when necessary, but for correct overriding of library interfaces by local extensions, you should call this function before calling tp_proxy_or_subclass_hook_on_interface_add() with first argument TP_TYPE_CHANNEL.

Since: 0.7.6


tp_channel_is_ready ()

gboolean
tp_channel_is_ready (TpChannel *self);

tp_channel_is_ready has been deprecated since version 0.17.6 and should not be used in newly-written code.

use tp_proxy_is_prepared() with TP_CHANNEL_FEATURE_CORE

Returns the same thing as the “channel-ready” property.

New code should use tp_proxy_is_prepared(), which is a more general form of this method.

For group channels, this method is equivalent to checking for the combination of TP_CHANNEL_FEATURE_CORE and TP_CHANNEL_FEATURE_GROUP; for non-group channels, it's equivalent to checking for TP_CHANNEL_FEATURE_CORE.

One important difference is that after “invalidated” is signalled, “channel-ready” keeps its current value - which might be TRUE, if the channel was successfully prepared before it became invalidated - but tp_proxy_is_prepared() returns FALSE for all features.

[skip]

Parameters

self

a channel

 

Returns

TRUE if introspection has completed

Since: 0.7.12


tp_channel_borrow_connection ()

TpConnection *
tp_channel_borrow_connection (TpChannel *self);

tp_channel_borrow_connection is deprecated and should not be used in newly-written code.

Since 0.19.9. New code should use tp_channel_get_connection() instead.

Returns the connection for this channel. The returned pointer is only valid while this channel is valid - reference it with g_object_ref() if needed.

Parameters

self

a channel

 

Returns

the value of “connection”.

[transfer none]

Since: 0.7.12


tp_channel_borrow_immutable_properties ()

GHashTable *
tp_channel_borrow_immutable_properties
                               (TpChannel *self);

tp_channel_borrow_immutable_properties is deprecated and should not be used in newly-written code.

Since 0.19.9. New code should use tp_channel_dup_immutable_properties() instead.

Returns the immutable D-Bus properties of this channel, the same as “channel-properties”.

The returned hash table should not be altered, and is not necessarily valid after the main loop is next re-entered. Copy it with g_boxed_copy() (its type is TP_HASH_TYPE_QUALIFIED_PROPERTY_VALUE_MAP) if a copy that remains valid must be kept.

If the “channel-properties” property was not set during construction (e.g. by calling tp_channel_new_from_properties()), a reasonable but possibly incomplete version will be made up from the values of individual properties; reading this property repeatedly may yield progressively more complete values until the TP_CHANNEL_FEATURE_CORE feature is prepared.

Parameters

self

a channel

 

Returns

a GHashTable where the keys are strings, D-Bus interface name + "." + property name, and the values are GValue instances.

[transfer none][element-type utf8 GObject.Value]


tp_channel_get_connection ()

TpConnection *
tp_channel_get_connection (TpChannel *self);

Returns the connection for this channel. The returned pointer is only valid while this channel is valid - reference it with g_object_ref() if needed.

Parameters

self

a channel

 

Returns

the value of “connection”.

[transfer none]

Since: 0.19.9


tp_channel_dup_immutable_properties ()

GVariant *
tp_channel_dup_immutable_properties (TpChannel *self);

Returns the immutable D-Bus properties of this channel, in a variant of type G_VARIANT_TYPE_VARDICT where the keys are strings, D-Bus interface name + "." + property name. Use g_variant_lookup() or g_variant_lookup_value() for convenient access to the values.

If the “channel-properties” property was not set during construction (e.g. by calling tp_channel_new_from_properties()), a reasonable but possibly incomplete version will be made up from the values of individual properties; reading this property repeatedly may yield progressively more complete values until the TP_CHANNEL_FEATURE_CORE feature is prepared.

This function should be used only by TpChannel subclasses, otherwise it is recommended to use individual property getters instead.

Parameters

self

a channel

 

Returns

a dictionary where the keys are strings, D-Bus interface name + "." + property name.

[transfer full]

Since: 0.19.9


tp_channel_get_channel_type ()

const gchar *
tp_channel_get_channel_type (TpChannel *self);

Get the D-Bus interface name representing this channel's type, if it has been discovered.

This is the same as the “channel-type” property; it isn't guaranteed to be non-NULL until the TP_CHANNEL_FEATURE_CORE feature has been prepared.

Parameters

self

a channel

 

Returns

the channel type, if the channel is ready; either the channel type or NULL, if the channel is not yet ready.

Since: 0.7.12


tp_channel_get_channel_type_id ()

GQuark
tp_channel_get_channel_type_id (TpChannel *self);

Get the D-Bus interface name representing this channel's type, as a GQuark, if it has been discovered.

This is the same as the “channel-type” property, except that it is a GQuark rather than a string. It isn't guaranteed to be nonzero until the TP_CHANNEL_FEATURE_CORE property is ready.

Parameters

self

a channel

 

Returns

the channel type, if the channel is ready; either the channel type or 0, if the channel is not yet ready.

Since: 0.7.12


tp_channel_get_handle ()

TpHandle
tp_channel_get_handle (TpChannel *self,
                       TpHandleType *handle_type);

Get the handle representing the contact, chatroom, etc. with which this channel communicates for its whole lifetime, or 0 if there is no such handle or it has not yet been discovered.

This is the same as the “handle” property. It isn't guaranteed to have its final value until the TP_CHANNEL_FEATURE_CORE feature is ready.

If handle_type is not NULL, the type of handle is written into it. This will be TP_UNKNOWN_HANDLE_TYPE if the handle has not yet been discovered, or TP_HANDLE_TYPE_NONE if there is no handle with which this channel will always communicate. This is the same as the “handle-type” property.

Parameters

self

a channel

 

handle_type

if not NULL, used to return the type of this handle.

[out]

Returns

the handle

Since: 0.7.12


tp_channel_get_identifier ()

const gchar *
tp_channel_get_identifier (TpChannel *self);

This channel's associated identifier, or the empty string if no identifier or unknown.

This is the same as the “identifier” property, and isn't guaranteed to be set until the TP_CHANNEL_FEATURE_CORE property is ready.

Changed in 0.11.4: as with “identifier”, this could previously either be NULL or the empty string if there was no suitable value. It is now non-NULL in all cases.

Parameters

self

a channel

 

Returns

the identifier

Since: 0.7.21


tp_channel_get_target_contact ()

TpContact *
tp_channel_get_target_contact (TpChannel *self);

tp_channel_get_initiator_handle ()

TpHandle
tp_channel_get_initiator_handle (TpChannel *self);

tp_channel_get_initiator_handle is deprecated and should not be used in newly-written code.

New code should use tp_channel_get_initiator_contact() instead.

                       const gchar *message,
                       GAsyncReadyCallback callback,
                       gpointer user_data);

Join channel self with message as join message.

When we joined the channel, callback will be called. You can then call tp_channel_join_finish() to get the result of the operation.

Note that unlike tp_channel_leave_async(), TP_CHANNEL_FEATURE_GROUP feature must be prepared before calling this function.

Parameters

self

a TpChannel

 

message

the join message

 

callback

a callback to call when we joined the channel

 

user_data

data to pass to callback

 

Since: 0.15.5


tp_channel_join_finish ()

gboolean
tp_channel_join_finish (TpChannel *self,
                        GAsyncResult *result,
                        GError **error);

Completes a call to tp_channel_join_async().

Parameters

self

a TpChannel

 

result

a GAsyncResult passed to the callback for tp_channel_join_async().

 

error

a GError to fill

 

Returns

TRUE if the channel was successfully joined; FALSE otherwise

Since: 0.15.5


tp_channel_leave_async ()

void
tp_channel_leave_async (TpChannel *self,
                        TpChannelGroupChangeReason reason,
                        const gchar *message,
                        GAsyncReadyCallback callback,
                        gpointer user_data);

Leave channel self with reason as reason and message as leave message. If self doesn't implement TP_IFACE_QUARK_CHANNEL_INTERFACE_GROUP or if for any reason we can't properly leave the channel, we close it.

When we left the channel, callback will be called. You can then call tp_channel_leave_finish() to get the result of the operation.

Note that unlike tp_channel_join_async(), TP_CHANNEL_FEATURE_GROUP feature does not have to be prepared and will be prepared for you. But this is a deprecated behaviour.

Parameters

self

a TpChannel

 

reason

the leave reason

 

message

the leave message

 

callback

a callback to call when we left the channel

 

user_data

data to pass to callback

 

Since: 0.13.10

gboolean
tp_channel_leave_finish (TpChannel *self,
                         GAsyncResult *result,
                         GError **error);

Completes a call to tp_channel_leave_async().

Parameters

self

a TpChannel

 

result

a GAsyncResult passed to the callback for tp_channel_leave_async().

 

error

a GError to fill

 

Returns

TRUE if the channel has been left; FALSE otherwise

tp_channel_close_async ()

void
tp_channel_close_async (TpChannel *self,
                        GAsyncReadyCallback callback,
                        gpointer user_data);

Close channel self . In most cases, it's generally cleaner to use tp_channel_leave_async() instead to properly leave and close the channel.

When the channel has been closed, callback will be called. You can then call tp_channel_close_finish() to get the result of the operation.

Parameters

self

a TpChannel

 

callback

a callback to call when we closed the channel, or NULL to ignore any reply

 

user_data

data to pass to callback

 

Since: 0.13.10

                         GError **error);

Finishes a call to tp_channel_leave_async().

Parameters

self

a TpChannel

 

result

a GAsyncResult passed to the callback for tp_channel_close_async().

 

error

a GError to fill

 

Returns

TRUE if the channel has been closed; FALSE otherwise

                          GAsyncReadyCallback callback,
                          gpointer user_data);

Destroy channel self . If self doesn't implement TP_IFACE_QUARK_CHANNEL_INTERFACE_DESTROYABLE or if for any reason we can't destroy the channel, we close it.

When the channel has been destroyed or closed, callback will be called. You can then call tp_channel_destroy_finish() to get the result of the operation.

Parameters

self

a TpChannel

 

callback

a callback to call when we left the channel

 

user_data

data to pass to callback

 

Since: 0.15.2


tp_channel_destroy_finish ()

TpChannelChatState
tp_channel_get_chat_state (TpChannel *self,
                           TpHandle contact);

tp_channel_get_chat_state is deprecated and should not be used in newly-written code.

Use tp_text_channel_get_chat_state() instead.

Return the chat state for the given contact. If tp_proxy_is_prepared() would return FALSE for the feature TP_CHANNEL_FEATURE_CHAT_STATES, the result will always be TP_CHANNEL_CHAT_STATE_INACTIVE.

Parameters

self

a channel

 

contact

a contact handle

 

Returns

the chat state for contact , or TP_CHANNEL_CHAT_STATE_INACTIVE if their chat state is not known

Since: 0.11.3


tp_channel_group_get_flags ()

TpChannelGroupFlags
tp_channel_group_get_flags (TpChannel *self);

Return the “group-flags” property (see the description of that property for notes on validity).

Parameters

self

a channel

 

Returns

the group flags, or 0

Since: 0.7.12


tp_channel_group_get_handle_owner ()

TpHandle
tp_channel_group_get_handle_owner (TpChannel *self,
                                   TpHandle handle);

tp_channel_group_get_handle_owner is deprecated and should not be used in newly-written code.

New code should use tp_channel_group_get_contact_owner() instead.

Synopsis (see below for further explanation):

  • if self is not a group or handle is not a member of this channel, result is undefined;

  • if TP_CHANNEL_FEATURE_GROUP has not yet been prepared, result is undefined;

  • if self does not have flags that include TP_CHANNEL_GROUP_FLAG_PROPERTIES, result is undefined;

  • if handle is channel-specific and its globally valid "owner" is known, return that owner;

  • if handle is channel-specific and its globally valid "owner" is unknown, return zero;

  • if handle is globally valid, return handle itself

Some channels (those with flags that include TP_CHANNEL_GROUP_FLAG_CHANNEL_SPECIFIC_HANDLES) have a concept of "channel-specific handles". These are handles that only have meaning within the context of the channel - for instance, in XMPP Multi-User Chat, participants in a chatroom are identified by an in-room JID consisting of the JID of the chatroom plus a local nickname.

Depending on the protocol and configuration, it might be possible to find out what globally valid handle (i.e. an identifier that you could add to your contact list) "owns" a channel-specific handle. For instance, in most XMPP MUC chatrooms, normal users cannot see what global JID corresponds to an in-room JID, but moderators can.

This is further complicated by the fact that channels with channel-specific handles can sometimes have members with globally valid handles (for instance, if you invite someone to an XMPP MUC using their globally valid JID, you would expect to see the handle representing that JID in the Group's remote-pending set).

This function's result is undefined unless the channel is ready and its flags include TP_CHANNEL_GROUP_FLAG_PROPERTIES (an implementation without extra D-Bus round trips is not possible using the older API).

Parameters

self

a channel

 

handle

a handle which is a member of this channel

 

Returns

the global handle that owns the given handle, or 0

tp_channel_group_get_contact_owner ()

TpContact *
tp_channel_group_get_contact_owner (TpChannel *self,
                                    TpContact *contact);

Synopsis (see below for further explanation):

  • if self is not a group or contact is not a member of this channel, result is undefined;

  • if TP_CHANNEL_FEATURE_CONTACTS has not yet been prepared, result is undefined;

  • if self does not have flags that include TP_CHANNEL_GROUP_FLAG_PROPERTIES, result is undefined;

  • if contact is channel-specific and its globally valid "owner" is known, return that owner;

  • if contact is channel-specific and its globally valid "owner" is unknown, return NULL;

  • if contact is globally valid, return contact itself

Some channels (those with flags that include TP_CHANNEL_GROUP_FLAG_CHANNEL_SPECIFIC_HANDLES) have a concept of "channel-specific contacts". These are contacts that only have meaning within the context of the channel - for instance, in XMPP Multi-User Chat, participants in a chatroom are identified by an in-room JID consisting of the JID of the chatroom plus a local nickname.

Depending on the protocol and configuration, it might be possible to find out what globally valid contact (i.e. a contact that you could add to your contact list) "owns" a channel-specific contact. For instance, in most XMPP MUC chatrooms, normal users cannot see what global JID corresponds to an in-room JID, but moderators can.

This is further complicated by the fact that channels with channel-specific contacts can sometimes have members with globally valid contacts (for instance, if you invite someone to an XMPP MUC using their globally valid JID, you would expect to see the contact representing that JID in the Group's remote-pending set).

Parameters

self

a channel

 

contact

                           GObject *weak_object);

Start a Close method call.

Request that the channel be closed. This is not the case until the <tp:member-ref>Closed</tp:member-ref> signal has been emitted, and depending on the connection manager this may simply remove you from the channel on the server, rather than causing it to stop existing entirely. Some channels such as contact list channels may not be closed.

Parameters

proxy

the TpProxy

 

timeout_ms

the timeout in milliseconds, or -1 to use the default

 

callback

called when the method call succeeds or fails; may be NULL to make a "fire and forget" call with no reply tracking

 

user_data

user-supplied data passed to the callback; must be NULL if callback is NULL

 

destroy

called with the user_data as argument, after the call has succeeded, failed or been cancelled; must be NULL if callback is NULL

 

weak_object

If not NULL, a GObject which will be weakly referenced; if it is destroyed, this call will automatically be cancelled. Must be NULL if callback is NULL

 

Returns

a TpProxyPendingCall representing the call in progress. It is borrowed from the object, and will become invalid when the callback is called, the call is cancelled or the TpProxy becomes invalid.

tp_cli_channel_run_close is deprecated and should not be used in newly-written code.

Call the method Close and run the main loop until it returns. Before calling this method, you must add a reference to any borrowed objects you need to keep, and generally ensure that everything is in a consistent state.

Request that the channel be closed. This is not the case until the <tp:member-ref>Closed</tp:member-ref> signal has been emitted, and depending on the connection manager this may simply remove you from the channel on the server, rather than causing it to stop existing entirely. Some channels such as contact list channels may not be closed.

Parameters

proxy

A TpChannel or subclass

 

timeout_ms

Timeout in milliseconds, or -1 for default

 

error

If not NULL, used to return errors if FALSE is returned

 

loop

If not NULL, set before re-entering the main loop, to point to a GMainLoop which can be used to cancel this call with g_main_loop_quit(), causing a return of FALSE with error set to TP_DBUS_ERROR_CANCELLED

tp_cli_channel_run_get_channel_type is deprecated and should not be used in newly-written code.

Use the ChannelType property if possible.

Call the method GetChannelType and run the main loop until it returns. Before calling this method, you must add a reference to any borrowed objects you need to keep, and generally ensure that everything is in a consistent state.

Returns the interface name for the type of this channel. Clients SHOULD use the <tp:member-ref>ChannelType</tp:member-ref> property instead, falling back to this method only if necessary. <tp:rationale> The GetAll method lets clients retrieve all properties in one round-trip. </tp:rationale>

Parameters

proxy

A TpChannel or subclass

 

timeout_ms

Timeout in milliseconds, or -1 for default

 

out_Channel_Type

Used to return an 'out' argument if TRUE is returned: The interface name

 

error

If not NULL, used to return errors if FALSE is returned

 

loop

If not NULL, set before re-entering the main loop, to point to a GMainLoop which can be used to cancel this call with g_main_loop_quit(), causing a return of FALSE with error set to TP_DBUS_ERROR_CANCELLED

 

Returns

TRUE on success, FALSE and sets error on error


tp_cli_channel_run_get_handle ()

gboolean
tp_cli_channel_run_get_handle (TpChannel *proxy,
                               gint timeout_ms,

                               GMainLoop **loop);

tp_cli_channel_run_get_handle is deprecated and should not be used in newly-written code.

Use the TargetHandleType and TargetHandle properties if possible.

Call the method GetHandle and run the main loop until it returns. Before calling this method, you must add a reference to any borrowed objects you need to keep, and generally ensure that everything is in a consistent state.

Returns the handle type and number if this channel represents a communication with a particular contact, room or server-stored list, or zero if it is transient and defined only by its contents. Clients SHOULD use the <tp:member-ref>TargetHandle</tp:member-ref> and <tp:member-ref>TargetHandleType</tp:member-ref> properties instead, falling back to this method only if necessary. <tp:rationale> The GetAll method lets clients retrieve all properties in one round-trip. </tp:rationale>

Parameters

proxy

A TpChannel or subclass

 

timeout_ms

Timeout in milliseconds, or -1 for default

 

out_Target_Handle_Type

Used to return an 'out' argument if TRUE is returned: The same as TargetHandleType.

 

out_Target_Handle

Used to return an 'out' argument if TRUE is returned: The same as TargetHandle.

 

error

If not NULL, used to return errors if FALSE is returned

 

loop

If not NULL, set before re-entering the main loop, to point to a GMainLoop which can be used to cancel this call with g_main_loop_quit(), causing a return of FALSE with error set to TP_DBUS_ERROR_CANCELLED

 

Returns

TRUE on success, FALSE and sets error on error

Parameters

proxy

A TpChannel or subclass

 

callback

Callback to be called when the signal is received

 

user_data

User-supplied data for the callback

Types and Values

struct TpChannel

struct TpChannel;

A proxy object for a Telepathy channel. A proxy object for a Telepathy channel. There are no interesting public struct fields.

(Changed in 0.7.12: the layout of the structure is visible, allowing subclassing.)

Since: 0.7.1


struct TpChannelClass

struct TpChannelClass {
    TpProxyClass parent_class;
};

The class of a TpChannel. In addition to parent_class there are four pointers reserved for possible future use.

(Changed in 0.7.12: the layout of the structure is visible, allowing subclassing.)

Members

Since: 0.7.1


TP_CHANNEL_FEATURE_CORE

#define             TP_CHANNEL_FEATURE_CORE

Expands to a call to a function that returns a quark for the "core" feature on a TpChannel.

When this feature is prepared, the basic Channel properties of the Channel have been retrieved and are available for use.

Specifically, this implies that:

(These are a subset of the guarantees offered by the older “channel-ready” and tp_channel_call_when_ready() mechanisms, which are now equivalent to (TP_CHANNEL_FEATURE_CORE, TP_CHANNEL_FEATURE_GROUP) if the channel is a group, or just TP_CHANNEL_FEATURE_CORE otherwise.)

One can ask for a feature to be prepared using the tp_proxy_prepare_async() function, and waiting for it to callback.

Since: 0.11.3


TP_CHANNEL_FEATURE_CONTACTS

#define             TP_CHANNEL_FEATURE_CONTACTS

Expands to a call to a function that returns a quark representing the Contacts features of a TpChannel.

When this feature is prepared, the TpContact objects of this channel are guaranteed to have all of the features previously passed to tp_simple_client_factory_add_contact_features() prepared.

On older connection managers, this feature may fail to prepare.

One can ask for a feature to be prepared using the tp_proxy_prepare_async() function, and waiting for it to callback.

Since: 0.15.6


TP_CHANNEL_FEATURE_CHAT_STATES

#define             TP_CHANNEL_FEATURE_CHAT_STATES

TP_CHANNEL_FEATURE_CHAT_STATES is deprecated and should not be used in newly-written code.

Use TP_TEXT_CHANNEL_FEATURE_CHAT_STATES instead.

Expands to a call to a function that returns a quark representing the chat states feature on a TpChannel.

When this feature is prepared, tp_channel_get_chat_state() and the “chat-state-changed” signal become useful.

One can ask for a feature to be prepared using the tp_proxy_prepare_async() function, and waiting for it to callback.

Since: 0.11.3


TP_CHANNEL_FEATURE_GROUP

#define             TP_CHANNEL_FEATURE_GROUP

Expands to a call to a function that returns a quark representing the Group features of a TpChannel.

When this feature is prepared, the Group properties of the Channel have been retrieved and are available for use, and change-notification has been set up for those that can change:

  • the initial value of the “group-self-handle” property will have been fetched and change notification will have been set up

  • the initial value of the “group-flags” property will have been fetched and change notification will have been set up

(These are the same guarantees offered for Group channels by the older “channel-ready” and tp_channel_call_when_ready() mechanisms.)

One can ask for a feature to be prepared using the tp_proxy_prepare_async() function, and waiting for it to callback.

Since: 0.11.3


TP_ERRORS_REMOVED_FROM_GROUP

#define TP_ERRORS_REMOVED_FROM_GROUP (tp_errors_removed_from_group_quark ())

GError domain representing the local user being removed from a channel with the Group interface. The code in a GError with this domain must be a member of TpChannelGroupChangeReason.

This error may be raised on non-Group channels with certain reason codes if there's no better error code to use (mainly TP_CHANNEL_GROUP_CHANGE_REASON_NONE).

This macro expands to a function call returning a GQuark.

Since: 0.7.1


TP_CHANNEL_FEATURE_PASSWORD

#define             TP_CHANNEL_FEATURE_PASSWORD

Expands to a call to a function that returns a quark representing the password feature on a TpChannel.

When this feature is prepared, tp_channel_password_needed() and the “password-needed” property become useful.

One can ask for a feature to be prepared using the tp_proxy_prepare_async() function, and waiting for it to callback.

Since: 0.15.2

Property Details

The “channel-properties” property

  “channel-properties”       GHashTable_gchararray+GValue_*

The immutable D-Bus properties of this channel, represented by a GHashTable where the keys are D-Bus interface name + "." + property name, and the values are GValue instances.

Read-only except during construction. If this is not provided during construction, a reasonable (but possibly incomplete) version will be made up from the values of individual properties; reading this property repeatedly may yield progressively more complete values until tp_proxy_prepare_async() has finished preparing TP_CHANNEL_FEATURE_CORE.

Owner: TpChannel

Flags: Read / Write / Construct Only


The “channel-ready” property

  “channel-ready”            gboolean

Initially FALSE; changes to TRUE when tp_proxy_prepare_async() has finished preparing TP_CHANNEL_FEATURE_CORE, and if the channel is a group, TP_CHANNEL_FEATURE_GROUP.

This is a less general form of tp_proxy_is_prepared(), which should be used in new code.

One important difference is that after “invalidated” is signalled, “channel-ready” keeps its current value - which might be TRUE, if the channel was successfully prepared before it became invalidated - but tp_proxy_is_prepared() returns FALSE for all features.

Change notification is via notify::channel-ready.

TpChannel:channel-ready has been deprecated since version 0.17.6 and should not be used in newly-written code.

use tp_proxy_is_prepared() with TP_CHANNEL_FEATURE_CORE for checks, or tp_proxy_prepare_async() for notification

Owner: TpChannel

Flags: Read

Default value: FALSE


The “connection” property

  “connection”               TpConnection *

The TpConnection to which this TpChannel belongs. Used for e.g. handle manipulation.

Owner: TpChannel

Flags: Read / Write / Construct Only


The “group-flags” property

  “group-flags”              guint

If the TP_CHANNEL_FEATURE_GROUP feature has been prepared successfully, TpChannelGroupFlags indicating the capabilities and behaviour of that group.

Otherwise, this may be 0.

Change notification is via notify::group-flags or TpChannel::group-flags-changed.

Owner: TpChannel

Flags: Read

Default value: 0

Since: 0.7.12


The “group-self-contact” property

  “group-self-contact”       TpContact *

If this channel is a group and TP_CHANNEL_FEATURE_CONTACTS has been prepared, and the user is a member of the group, the TpContact representing them in this group.

Otherwise, the result may be either a contact representing the user, or NULL.

Change notification is via notify::group-self-contact.

Owner: TpChannel

Flags: Read

Since: 0.15.6


The “group-self-handle” property

  “group-self-handle”        guint

If this channel is a group and TP_CHANNEL_FEATURE_GROUP has been prepared, and the user is a member of the group, the TpHandle representing them in this group.

Otherwise, the result may be either a handle representing the user, or 0.

Change notification is via notify::group-self-handle.

TpChannel:group-self-handle is deprecated and should not be used in newly-written code.

Use “group-self-contact” instead.

Owner: TpChannel

Flags: Read

Default value: 0

Since: 0.7.12


The “identifier” property

  “identifier”               gchar *

This channel's associated identifier, or the empty string if it has handle type TP_HANDLE_TYPE_NONE.

For channels where “handle” is non-zero, this is the result of inspecting “handle”.

This is not guaranteed to be set until tp_proxy_prepare_async() has finished preparing TP_CHANNEL_FEATURE_CORE; until then, it may be the empty string.

Changed in 0.11.4: this property is never NULL. Previously, it was NULL before an identifier was known, or when a channel with no TargetID D-Bus property had TargetHandleType TP_HANDLE_TYPE_NONE.

Owner: TpChannel

Flags: Read

Default value: ""


The “initiator-contact” property

  “initiator-contact”        TpContact *

The TpContact of the initiator of this channel, or NULL if there is no particular initiator.

If the channel was initiated by a remote contact, this represents that contact, and “requested” will be FALSE. For instance, for an incoming call this property indicates the caller, and for a chatroom invitation this property indicates who sent the invitation.

If the channel was requested by the local user, “requested” will be TRUE, and this property may be the “group-self-contact” or “self-contact”.

If the channel appeared for some other reason (for instance as a side-effect of connecting to the server), this property may be NULL.

This is not guaranteed to be set until tp_proxy_prepare_async() has finished preparing TP_CHANNEL_FEATURE_CONTACTS; until then, it may be NULL.

Owner: TpChannel

Flags: Read

Since: 0.15.6


The “initiator-handle” property

  “initiator-handle”         guint

The TP_HANDLE_TYPE_CONTACT TpHandle of the initiator of this channel, or 0 if there is no particular initiator.

If the channel was initiated by a remote contact, this handle represents that contact, and “requested” will be FALSE. For instance, for an incoming call this property indicates the caller, and for a chatroom invitation this property indicates who sent the invitation.

If the channel was requested by the local user, “requested” will be TRUE, and this property may be the “group-self-handle” or “self-handle”.

If the channel appeared for some other reason (for instance as a side-effect of connecting to the server), this property may be 0.

This is not guaranteed to be set until tp_proxy_prepare_async() has finished preparing TP_CHANNEL_FEATURE_CORE; until then, it may be 0.

TpChannel:initiator-handle is deprecated and should not be used in newly-written code.

Use “initiator-contact” instead.

Owner: TpChannel

Flags: Read

Default value: 0

Since: 0.11.15


The “initiator-identifier” property

  “initiator-identifier”     gchar *

If “initiator-handle” is 0, this will always be "". Otherwise, this will be the “identifier” of the contact with that handle.

This is not guaranteed to be set until tp_proxy_prepare_async() has finished preparing TP_CHANNEL_FEATURE_CORE; until then, it may be the empty string.

TpChannel:initiator-identifier is deprecated and should not be used in newly-written code.

Use “initiator-contact” instead.

Owner: TpChannel

Flags: Read

Default value: ""

Since: 0.11.15


The “password-needed” property

  “password-needed”          gboolean

If TRUE, tp_channel_provide_password_async() has to be called to be able to join the channel.

This is not guaranteed to be meaningful until tp_proxy_prepare_async() has finished preparing TP_CHANNEL_FEATURE_PASSWORD; until then, it may return FALSE even if the channel is actually protected by a password. Preparing TP_CHANNEL_FEATURE_PASSWORD also ensures that the notify::password-needed signal will be fired when this property changes.

Owner: TpChannel

Flags: Read

Default value: FALSE

Since: 0.15.2


The “requested” property

  “requested”                gboolean

TRUE if this channel was created in response to a local request, such as a call to tp_account_channel_request_create_channel_async(). FALSE if this channel was initiated by a remote contact (the “initiator-handle”), or if it appeared as a side-effect of some other action.

For instance, this is FALSE on incoming calls and file transfers, remotely-initiated 1-1 text conversations, and invitations to chatrooms, and TRUE on outgoing calls and file transfers, locally-initiated 1-1 text conversations, and chatrooms joined by local user action.

This is not guaranteed to be meaningful until tp_proxy_prepare_async() has finished preparing TP_CHANNEL_FEATURE_CORE; until then, it may return FALSE even if the channel was actually requested.

Owner: TpChannel

Flags: Read

Default value: FALSE

Since: 0.11.15


The “target-contact” property

  “target-contact”           TpContact *

If this channel is for communication with a single contact (that is, “handle-type” is TP_HANDLE_TYPE_CONTACT), then a TpContact representing the remote contact. For chat rooms, contact search channels and other channels without a single remote contact, NULL.

This is not guaranteed to be set until tp_proxy_prepare_async() has finished preparing TP_CHANNEL_FEATURE_CONTACTS; until then, it may be NULL.

Owner: TpChannel

Flags: Read

Since: 0.15.6
