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.

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.
Gets a named field from the objects table of associations (see g_object_set_data()).

Gets a property of an object.

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.

Checks whether object has a [floating][floating-ref] reference.
Return %TRUE if feature has been prepared successfully, or %FALSE if
feature has not been requested, has not been prepared yet, or is not
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.
the name of a property installed on the class of object.
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:
g_object_notify_by_pspec (self, properties[PROP_FOO]);
the #GParamSpec of a property installed on the class of object.
#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.
an array of desired features, ending with 0; %NULL is equivalent to an array containing only 0
if not %NULL, called exactly once, when the features have all been prepared or failed to prepare, or after the proxy is invalidated
Check for error in a call to tp_proxy_prepare_async(). An error here
generally indicates that either the asynchronous call was cancelled,
or self has emitted #TpProxy::invalidated.
the result passed to the callback of tp_proxy_prepare_async()
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().
Request that a remote contact stops or starts sending on this stream.
The #TpCallStream:can-request-receiving property defines whether the protocol allows the local user to request the other side start sending on this stream.
If receive is %TRUE, request that the given contact starts to send media.
If receive is %FALSE, request that the given contact stops sending media.

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.

Remove a specified datum from the object's data associations, without invoking the association's destroy handler.
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().
A #GQuark, naming the user data pointer
Reverts the effect of a previous call to
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 #TpCallStream 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_CALL_STREAM.
Find the #GParamSpec with the given name for an

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.
