The D-Bus bus name for this object. Read-only except during construction.
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 #TpProxy::invalidated is signalled, #TpChannel: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.
The #TpConnection to which this #TpChannel belongs. Used for e.g. handle manipulation.
The D-Bus daemon for this object (this object itself, if it is a TpDBusDaemon). Read-only except during construction.
The #TpSimpleClientFactory used to create this proxy, or %NULL if this proxy was not created through a factory.
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.
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.
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.
This channel's associated identifier, or the empty string if it has handle type %TP_HANDLE_TYPE_NONE.
For channels where #TpChannelIface:handle is non-zero, this is the result of inspecting #TpChannelIface: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.
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 #TpChannel: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, #TpChannel:requested will be %TRUE, and this property may be the #TpChannel:group-self-contact or #TpConnection: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.
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 #TpChannel: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, #TpChannel:requested will be %TRUE, and this property may be the #TpChannel:group-self-handle or #TpConnection: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.
If #TpChannel:initiator-handle is 0, this will always be "". Otherwise, this will be the #TpContact: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.
Known D-Bus interface names for this object.
The D-Bus object path for this object. Read-only except during construction.
A %G_VARIANT_TYPE_VARDICT representing the parameters of the tube.
Will be %NULL for outgoing tubes until the tube has been offered.
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.
%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 #TpChannel: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.
A string representing the service name that will be used over the tube.
If this channel is for communication with a single contact (that is, #TpChannelIface: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.
Accept an incoming D-Bus tube. When the tube has been accepted
callback will be called. You can then call
tp_dbus_tube_channel_accept_finish() to get the #GDBusConnection that will
be used to communicate through the tube.
a callback to call when the tube has been offered
Finishes to accept an incoming D-Bus tube. The returned #GDBusConnection is ready to be used to exchange data through the tube.
a #GAsyncResult
Creates a binding between source_property on source and target_property
on target.
Whenever the source_property is changed the target_property is
updated using the same value. For instance:
g_object_bind_property (action, "active", widget, "sensitive", 0);
Will result in the "sensitive" property of the widget #GObject instance to be updated with the same value of the "active" property of the action #GObject instance.
If flags contains %G_BINDING_BIDIRECTIONAL then the binding will be mutual:
if target_property on target changes then the source_property on source
will be updated as well.
The binding will automatically be removed when either the source or the
target instances are finalized. To remove the binding without affecting the
source and the target you can just call g_object_unref() on the returned
#GBinding instance.
Removing the binding by calling g_object_unref() on it must only be done if
the binding, source and target are only used from a single thread and it
is clear that both source and target outlive the binding. Especially it
is not safe to rely on this if the binding, source or target can be
finalized from different threads. Keep another reference to the binding and
use g_binding_unbind() instead to be on the safe side.
A #GObject can have multiple bindings.

Creates a binding between source_property on source and target_property
on target, allowing you to set the transformation functions to be used by
the binding.
This function is the language bindings friendly version of g_object_bind_property_full(), using #GClosures instead of function pointers.

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.
Returns the immutable D-Bus properties of this channel, the same as #TpChannel: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 #TpChannel: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.
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.
a callback to call when we closed the channel, or %NULL to ignore any reply
Finishes a call to tp_channel_leave_async().
a #GAsyncResult passed to the callback for tp_channel_close_async().
Convert a D-Bus error name into a GError as if it was returned by a method on this proxy. This method is useful when D-Bus error names are emitted in signals, such as Connection.ConnectionError and Group.MembersChangedDetailed.

a debug message that accompanied the error name, or %NULL
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.
a callback to call when we left the channel
Completes a call to tp_channel_destroy_async().
a #GAsyncResult passed to the callback for tp_channel_destroy_async().
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 #TpChannel: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.
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.
This function is intended for #GObject implementations to re-enforce a [floating][floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling g_object_ref_sink().
Increases the freeze count on object. If the freeze count is
non-zero, the emission of "notify" signals on object is
stopped. The signals are queued until the freeze count is decreased
to zero. Duplicate notifications are squashed so that at most one
#GObject::notify signal is emitted for each property modified while the
object is frozen.
This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.
Get the D-Bus interface name representing this channel's type, if it has been discovered.
This is the same as the #TpChannelIface:channel-type property; it isn't guaranteed to be non-%NULL until the %TP_CHANNEL_FEATURE_CORE feature has been prepared.
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 #TpChannelIface: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.
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.
a contact handle
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.
Gets a named field from the objects table of associations (see g_object_set_data()).
name of the key for that association
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 #TpChannelIface: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
#TpChannelIface:handle-type property.
This channel's associated identifier, or the empty string if no identifier or unknown.
This is the same as the #TpChannel: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 #TpChannel: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.
Gets a property of an object.
The value can be:
In general, a copy is made of the property contents and the caller is responsible for freeing the memory by calling g_value_unset().
Note that g_object_get_property() is really intended for language bindings, g_object_get() is much more convenient for C programming.

Synopsis (see below for further explanation):
self is not a group or contact is not a member of this channel,
result is undefined;self does not have flags that include
%TP_CHANNEL_GROUP_FLAG_PROPERTIES,
result is undefined;contact is channel-specific and its globally valid "owner" is known,
return that owner;contact is channel-specific and its globally valid "owner" is unknown,
return %NULL;contact is globally valid, return contact itselfSome 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).

Return whether this proxy is known to have a particular interface. In versions older than 0.11.11, this was a macro wrapper around tp_proxy_has_interface_by_id().
For objects that discover their interfaces at runtime, this method will indicate that interfaces are missing until they are known to be present. In subclasses that define features for use with tp_proxy_prepare_async(), successfully preparing the "core" feature for that subclass (such as %TP_CHANNEL_FEATURE_CORE or %TP_CONNECTION_FEATURE_CORE) implies that the interfaces are known.
the D-Bus interface required, as a string
Return whether this proxy is known to have a particular interface, by its quark ID. This is equivalent to using g_quark_to_string() followed by tp_proxy_has_interface(), but more efficient.

Checks whether object has a [floating][floating-ref] reference.
Return %TRUE if feature has been prepared successfully, or %FALSE if

available on this object at all.
(For instance, if feature is %TP_CHANNEL_FEATURE_CHAT_STATES and self
is a #TpChannel in a protocol that doesn't actually implement chat states,
or is not a #TpChannel at all, then this method will return %FALSE.)
To prepare features, call tp_proxy_prepare_async().

Emits a "notify" signal for the property property_name on object.
When possible, eg. when signaling a property change from within the class that registered the property, you should use g_object_notify_by_pspec() instead.
Note that emission of the notify signal may be blocked with g_object_freeze_notify(). In this case, the signal emissions are queued and will be emitted (in reverse order) when g_object_thaw_notify() is called.

Emits a "notify" signal for the property specified by pspec on object.
This function omits the property name lookup, hence it is faster than g_object_notify().
One way to avoid using g_object_notify() from within the class that registered the properties, and using g_object_notify_by_pspec() instead, is to store the GParamSpec used with g_object_class_install_property() inside a static array, e.g.:
enum
{
PROP_0,
PROP_FOO,
PROP_LAST
};
static GParamSpec *properties[PROP_LAST];
static void
my_object_class_init (MyObjectClass *klass)
{
properties[PROP_FOO] = g_param_spec_int ("foo", "Foo", "The foo",
0, 100,
50,
G_PARAM_READWRITE);
g_object_class_install_property (gobject_class,
PROP_FOO,
properties[PROP_FOO]);
}
and then notify a change on the "foo" property with:

#TpProxy itself does not support any features, but subclasses like #TpChannel can support features, which can either be core functionality like %TP_CHANNEL_FEATURE_CORE, or extended functionality like %TP_CHANNEL_FEATURE_CHAT_STATES.
Proxy instances start with no features prepared. When features are requested via tp_proxy_prepare_async(), the proxy starts to do the necessary setup to use those features.
tp_proxy_prepare_async() always waits for core functionality of the proxy's class to be prepared, even if it is not specifically requested: for instance, because %TP_CHANNEL_FEATURE_CORE is core functionality of a #TpChannel,
|[ TpChannel *channel = ...;
tp_proxy_prepare_async (channel, NULL, callback, user_data);
is equivalent to
|[
TpChannel *channel = ...;
GQuark features[] = { TP_CHANNEL_FEATURE_CORE, 0 };
tp_proxy_prepare_async (channel, features, callback, user_data);
If a feature represents core functionality (like %TP_CHANNEL_FEATURE_CORE), failure to prepare it will result in tp_proxy_prepare_async() finishing unsuccessfully: if failure to prepare the feature indicates that the proxy is no longer useful, it will also emit #TpProxy::invalidated.
If a feature represents non-essential functionality (like %TP_CHANNEL_FEATURE_CHAT_STATES), or is not supported by the object at all, then failure to prepare it is not fatal: tp_proxy_prepare_async() will complete successfully, but tp_proxy_is_prepared() will still return %FALSE for the feature, and accessor methods for the feature will typically return a dummy value.
Some #TpProxy subclasses automatically start to prepare their core features when instantiated, and features will sometimes become prepared as a side-effect of other actions, but to ensure that a feature is present you must generally call tp_proxy_prepare_async() and wait for the result.

Provide password so that self can be joined.
This function must be called with the correct password in order for
channel joining to proceed if the TpChannel:password-needed property
is set.

called. You can then call tp_channel_provide_password_finish()
to get the result of the operation.

Increase the reference count of object, and possibly remove the
[floating][floating-ref] reference, if object has a floating reference.
In other words, if the object is floating, then this call "assumes ownership" of the floating reference, converting it to a normal reference by clearing the floating flag while leaving the reference count unchanged. If the object is not floating, then this call adds a new normal reference increasing the reference count by one.
Since GLib 2.56, the type of object will be propagated to the return type
under the same conditions as for g_object_ref().
Releases all references to other objects. This can be used to break reference cycles.
This function should only be called from object system implementations.
Each object carries around a table of associations from strings to pointers. This function lets you set an association.
If the object already had an association with that name, the old association will be destroyed.
Internally, the key is converted to a #GQuark using g_quark_from_string().
This means a copy of key is kept permanently (even after object has been
finalized) — so it is recommended to only use a small, bounded set of values
for key in your program, to avoid the #GQuark storage growing unbounded.

Sets a property on an object.

name of the key
This function gets back user data pointers stored via
g_object_set_qdata() and removes the data from object
without invoking its destroy() function (if any was
set).
Usually, calling this function is only required to update
user data pointers with a destroy notifier, for example:
void
object_add_to_user_list (GObject *object,
const gchar *new_string)
{
// the quark, naming the object data
GQuark quark_string_list = g_quark_from_static_string ("my-string-list");
// retrieve the old string list
GList *list = g_object_steal_qdata (object, quark_string_list);
// prepend new string
list = g_list_prepend (list, g_strdup (new_string));
// this changed 'list', so we need to set it again
g_object_set_qdata_full (object, quark_string_list, list, free_string_list);
}
static void
free_string_list (gpointer data)
{
GList *node, *list = data;
for (node = list; node; node = node->next)
g_free (node->data);
g_list_free (list);
}
Using g_object_get_qdata() in the above example, instead of g_object_steal_qdata() would have left the destroy function set, and thus the partial string list would have been freed upon g_object_set_qdata_full().

g_object_freeze_notify(). The freeze count is decreased on object
and when it reaches zero, queued "notify" signals are emitted.
Duplicate notifications for each property are squashed so that at most one #GObject::notify signal is emitted for each property, in the reverse order in which they have been queued.
It is an error to call this function when the freeze count is zero.
Decreases the reference count of object. When its reference count
drops to 0, the object is finalized (i.e. its memory is freed).
If the pointer to the #GObject may be reused in future (for example, if it is an instance variable of another object), it is recommended to clear the pointer to %NULL rather than retain a dangling pointer to a potentially invalid #GObject instance. Use g_clear_object() for this.
This function essentially limits the life time of the closure to
the life time of the object. That is, when the object is finalized,
the closure is invalidated by calling g_closure_invalidate() on
it, in order to prevent invocations of the closure with a finalized
(nonexisting) object. Also, g_object_ref() and g_object_unref() are
added as marshal guards to the closure, to ensure that an extra
reference count is held on object during invocation of the
closure. Usually, this function will be called on closures that
use this object as closure data.
#GClosure to watch
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.
Find the #GParamSpec with the given name for an
interface. Generally, the interface vtable passed in as g_iface
will be the default vtable from g_type_default_interface_ref(), or,
if you know the interface has already been loaded,
g_type_default_interface_peek().
any interface vtable for the interface, or the default vtable for the interface
name of a property to look up.
Add a property to an interface; this is only useful for interfaces that are added to GObject-derived types. Adding a property to an interface forces all objects classes with that interface to have a compatible property. The compatible property could be a newly created #GParamSpec, but normally g_object_class_override_property() will be used so that the object class only needs to provide an implementation and inherits the property description, default value, bounds, and so forth from the interface property.
This function is meant to be called from the interface's default
vtable initialization function (the class_init member of
#GTypeInfo.) It must not be called after after class_init has
been called for any object types implementing this interface.
If pspec is a floating reference, it will be consumed.
