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.

Called by an approver to accept a channel bundle and request that the given handler be used to handle it.
If successful, this method will cause the #TpProxy::invalidated signal to be emitted with the TP_DBUS_ERROR_OBJECT_REMOVED error code.
However, this method may fail because the dispatch has already been completed and the object has already gone. If this occurs, it indicates that another approver has asked for the bundle to be handled by a particular handler. The approver MUST NOT attempt to interact with the channels further in this case, unless it is separately invoked as the handler.
Approvers which are also channel handlers SHOULD use tp_channel_dispatch_operation_claim_async() instead of tp_channel_dispatch_operation_handle_with_async() to request that they can handle a channel bundle themselves.

a #GAsyncResult
A variant of tp_channel_dispatch_operation_handle_with_async() allowing the approver to pass an user action time. This timestamp will be passed to the Handler when HandleChannels is called.
If an X server timestamp for the user action causing this method call is
available, user_action_time
should be this timestamp (for instance, the
result of gdk_event_get_time() if it is not %GDK_CURRENT_TIME). Otherwise, it
may be %TP_USER_ACTION_TIME_NOT_USER_ACTION to behave as if there was no
user action or it happened a long time ago, or
%TP_USER_ACTION_TIME_CURRENT_TIME to have the Handler behave as though the
user action had just happened (resembling, but not numerically equal to,
%GDK_CURRENT_TIME).

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.

Return %TRUE if feature

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.

Check for error in a call to tp_proxy_prepare_async(). An error here
generally indicates that either the asynchronous call was cancelled,

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.

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 TpChannelDispatchOperation 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_DISPATCH_OPERATION.
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.

One of the channel dispatcher's functions is to offer incoming channels to Approver clients for approval. An approver should generally ask the user whether they want to participate in the requested communication channels (join the chat or chatroom, answer the call, accept the file transfer, or whatever is appropriate). A collection of channels offered in this way is represented by a ChannelDispatchOperation object.
If the user wishes to accept the communication channels, the approver should call tp_cli_channel_dispatch_operation_call_handle_with() to indicate the user's or approver's preferred handler for the channels (the empty string indicates no particular preference, and will cause any suitable handler to be used).
If the user wishes to reject the communication channels, or if the user accepts the channels and the approver will handle them itself, the approver should call tp_cli_channel_dispatch_operation_call_claim(). If this method succeeds, the approver immediately has control over the channels as their primary handler, and may do anything with them (in particular, it may close them in whatever way seems most appropriate).
There are various situations in which the channel dispatch operation will be closed, causing the #TpProxy::invalidated signal to be emitted. If this happens, the approver should stop prompting the user.
Because all approvers are launched simultaneously, the user might respond to another approver; if this happens, the #TpProxy::invalidated signal will be emitted with the domain %TP_DBUS_ERRORS and the error code %TP_DBUS_ERROR_OBJECT_REMOVED.
If a channel closes, the #TpChannelDispatchOperation::channel-lost signal is emitted. If all channels close, there is nothing more to dispatch, so the #TpProxy::invalidated signal will be emitted with the domain %TP_DBUS_ERRORS and the error code %TP_DBUS_ERROR_OBJECT_REMOVED.
If the channel dispatcher crashes or exits, the #TpProxy::invalidated signal will be emitted with the domain %TP_DBUS_ERRORS and the error code %TP_DBUS_ERROR_NAME_OWNER_LOST. In a high-quality implementation, the dispatcher should be restarted, at which point it will create new channel dispatch operations for any undispatched channels, and the approver will be notified again.
Creating a #TpChannelDispatchOperation directly is deprecated: it should only be created via a #TpBaseClient.
Since 0.16, #TpChannelDispatchOperation always has a non-%NULL #TpProxy:factory, which will be propagated to the #TpAccount, #TpConnection and #TpChannel.
