Description

TpDBusTubeChannel provides API for working with D-Bus tube channels, which allow applications to open D-Bus connections to a contact or chat room.

To create a new outgoing D-Bus tube channel, do something like:

Details

struct TpDBusTubeChannel

struct TpDBusTubeChannel;

Data structure representing a TpDBusTubeChannel.

Since 0.18.0


struct TpDBusTubeChannelClass

struct TpDBusTubeChannelClass {
};

The class of a TpDBusTubeChannel.

Since 0.18.0


TP_DBUS_TUBE_CHANNEL_FEATURE_CORE

#define             TP_DBUS_TUBE_CHANNEL_FEATURE_CORE

Expands to a call to a function that returns a quark representing the core feature of a TpDBusTubeChannel.

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

Since 0.18.0


tp_dbus_tube_channel_get_parameters ()

GHashTable *        tp_dbus_tube_channel_get_parameters (TpDBusTubeChannel *self);

Return the "parameters" property

self :

a TpDBusTubeChannel

Returns :

the value of "parameters". [transfer none][element-type utf8 GObject.Value]

Since 0.18.0


tp_dbus_tube_channel_dup_parameters_vardict ()

GVariant *          tp_dbus_tube_channel_dup_parameters_vardict
                                                        (TpDBusTubeChannel *self);

Return the parameters of the dbus-tube channel in a variant of type G_VARIANT_TYPE_VARDICT whose keys are strings representing parameter names and values are variants representing corresponding parameter values set by the offerer when offering this channel.

The GVariant returned is NULL if this is an outgoing tube that has not yet been offered or the parameters property has not been set.

Use g_variant_lookup(), g_variant_lookup_value(), or tp_vardict_get_uint32() and similar functions for convenient access to the values.

self :

a TpDBusTubeChannel

Returns :

a new reference to a GVariant. [transfer full]

Since 0.19.10


tp_dbus_tube_channel_get_service_name ()

const gchar *       tp_dbus_tube_channel_get_service_name
                                                        (TpDBusTubeChannel *self);

Return the "service-name" property

self :

a TpDBusTubeChannel

Returns :

the value of "service-name". [transfer none]

Since 0.18.0


tp_dbus_tube_channel_offer_async ()

void                tp_dbus_tube_channel_offer_async    (TpDBusTubeChannel *self,
                                                         GHashTable *params,

                                                         gpointer user_data);

Offer an outgoing D-Bus tube. When the tube has been offered and accepted callback will be called. You can then call tp_dbus_tube_channel_offer_finish() to get the GDBusConnection that will be used to communicate through the tube.

self :

an outgoing TpDBusTubeChannel

params :

parameters of the tube, or NULL. [allow-none][transfer none]

callback :

a callback to call when the tube has been offered

user_data :

data to pass to callback

Since 0.18.0


tp_dbus_tube_channel_offer_finish ()

GDBusConnection *   tp_dbus_tube_channel_offer_finish   (TpDBusTubeChannel *self,

Property Details

The "parameters" property

  "parameters"               GHashTable_gchararray+GValue_*  : Read

A string to GValue GHashTable representing the parameters of the tube.

Will be NULL for outgoing tubes until the tube has been offered.

In high-level language bindings, use tp_dbus_tube_channel_dup_parameters_vardict() to get the same information in a more convenient format.

Since 0.18.0


The "parameters-vardict" property

  "parameters-vardict"       GVariant*             : Read

A G_VARIANT_TYPE_VARDICT representing the parameters of the tube.

Will be NULL for outgoing tubes until the tube has been offered.

Allowed values: GVariant<a{sv}>

Default value: NULL

Since 0.19.10


The "service-name" property

  "service-name"             gchar*                : Read

A string representing the service name that will be used over the tube.

Default value: NULL

Since 0.18.0
