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.Object instance to be updated with the same value of the "active" property of the action GObject.Object instance.
If flags contains GObject.BindingFlags.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
GObject.Binding 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.

If flags contains GObject.BindingFlags.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 transform_from function is only used in case
of bidirectional bindings, otherwise it will be ignored
The binding will automatically be removed when either the source or the
target instances are finalized. This will release the reference that is
being held on the GObject.Binding instance; if you want to hold on to the
GObject.Binding instance, you will need to hold a reference to it.
To remove the binding, call g_binding_unbind().
A GObject.Object can have multiple bindings.
The same user_data parameter will be used for both transform_to
and transform_from transformation functions; the notify function will
be called once, when the binding is removed. If you need different data

This function is intended for GObject.Object 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.Object::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.

Initializes the object implementing the interface.
This method is intended for language bindings. If writing in C,
g_initable_new() should typically be used instead.
The object must be initialized before any real use after initial
construction, either with this function or g_async_initable_init_async().
Implementations may also support cancellation. If cancellable is not null,
then initialization can be cancelled by triggering the cancellable object
from another thread. If the operation was cancelled, the error
Gio.IOErrorEnum.CANCELLED will be returned. If cancellable is not null and
the object doesn't support cancellable initialization the error
Gio.IOErrorEnum.NOT_SUPPORTED will be returned.
If the object is not initialized, or initialization returns with an
error, then all operations on the object except g_object_ref() and
g_object_unref() are considered to be invalid, and have undefined
behaviour. See the [description][iface@Gio.Initable#description] for more details.
Callers should not assume that a class which implements Gio.Initable can be
initialized multiple times, unless the class explicitly documents itself as
supporting this. Generally, a class’ implementation of init() can assume
(and assert) that it will only be called once. Previously, this documentation
recommended all Gio.Initable implementations should be idempotent; that
recommendation was relaxed in GLib 2.54.
If a class explicitly supports being initialized multiple times, it is recommended that the method is idempotent: multiple calls with the same arguments should return the same results. Only the first call initializes the object; further calls return the result of the first call.
One reason why a class might need to support idempotent initialization is if
it is designed to be used via the singleton pattern, with a
GObject.ObjectClass.constructor that sometimes returns an existing instance.
In this pattern, a caller would expect to be able to call g_initable_init()
on the result of g_object_new(), regardless of whether it is in fact a new
instance.

true if successful. If an error has occurred, this function will return false and set error appropriately if present.
Starts asynchronous initialization of the object implementing the
interface. This must be done before any real use of the object after
initial construction. If the object also implements Gio.Initable you can
optionally call g_initable_init() instead.
This method is intended for language bindings. If writing in C,
g_async_initable_new_async() should typically be used instead.
When the initialization is finished, callback will be called. You can
then call g_async_initable_init_finish() to get the result of the
initialization.
Implementations may also support cancellation. If cancellable is not
null, then initialization can be cancelled by triggering the cancellable
object from another thread. If the operation was cancelled, the error
Gio.IOErrorEnum.CANCELLED will be returned. If cancellable is not null, and
the object doesn't support cancellable initialization, the error
Gio.IOErrorEnum.NOT_SUPPORTED will be returned.
As with Gio.Initable, if the object is not initialized, or initialization
returns with an error, then all operations on the object except
g_object_ref() and g_object_unref() are considered to be invalid, and
have undefined behaviour. They will often fail with g_critical() or
g_warning(), but this must not be relied on.
Callers should not assume that a class which implements Gio.AsyncInitable can
be initialized multiple times; for more information, see g_initable_init().
If a class explicitly supports being initialized multiple times,
implementation requires yielding all subsequent calls to init_async() on the
results of the first call.
For classes that also support the Gio.Initable interface, the default
implementation of this method will run the g_initable_init() function
in a thread, so if you want to support asynchronous initialization via
threads, just implement the Gio.AsyncInitable interface without overriding
any interface methods.

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.:
typedef enum
{
PROP_FOO = 1,
PROP_LAST
} MyObjectProperty;
static GParamSpec *properties[PROP_LAST];
static void
my_object_class_init (MyObjectClass *klass)
{
properties[PROP_FOO] = g_param_spec_int ("foo", NULL, NULL,
0, 100,
50,
G_PARAM_READWRITE | G_PARAM_STATIC_STRINGS);
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 GObject.ParamSpec of a property installed on the class of object.
Increases the reference count of object.
Since GLib 2.56, if GLIB_VERSION_MAX_ALLOWED is 2.56 or greater, the type
of object will be propagated to the return type (using the GCC typeof()
extension), so any casting the caller needs to do on the return type must be
explicit.
the same object
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.
Sets multiple properties of an object at once. The properties argument should be a dictionary mapping property names to values.
Object containing the properties to set
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 GLib.Quark 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 GLib.Quark storage growing unbounded.

the data if found, or null if no such data exists.
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().

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.Object::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.Object 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.Object instance. Use g_clear_object() for this.

Virtualvfunc_the constructed function is called by g_object_new() as the
final step of the object creation process. At the point of the call, all
construction properties have been set on the object. The purpose of this
call is to allow for object initialisation steps that can only be performed
after construction properties have been set. constructed implementors
should chain up to the constructed call of their parent class to allow it
to complete its initialisation.
Virtualvfunc_Virtualvfunc_the dispose function is supposed to drop all references to other
objects, but keep the instance otherwise intact, so that client method
invocations still work. It may be run multiple times (due to reference
loops). Before returning, dispose should chain up to the dispose method
of the parent class.
Virtualvfunc_instance finalization function, should finish the finalization of
the instance begun in dispose and chain up to the finalize method of the
parent class.
Virtualvfunc_Virtualvfunc_Initializes the object implementing the interface.
This method is intended for language bindings. If writing in C,
g_initable_new() should typically be used instead.
The object must be initialized before any real use after initial
construction, either with this function or g_async_initable_init_async().
Implementations may also support cancellation. If cancellable is not null,
then initialization can be cancelled by triggering the cancellable object
from another thread. If the operation was cancelled, the error
Gio.IOErrorEnum.CANCELLED will be returned. If cancellable is not null and
the object doesn't support cancellable initialization the error
Gio.IOErrorEnum.NOT_SUPPORTED will be returned.
If the object is not initialized, or initialization returns with an
error, then all operations on the object except g_object_ref() and
g_object_unref() are considered to be invalid, and have undefined
behaviour. See the [description][iface@Gio.Initable#description] for more details.
Callers should not assume that a class which implements Gio.Initable can be
initialized multiple times, unless the class explicitly documents itself as
supporting this. Generally, a class’ implementation of init() can assume
(and assert) that it will only be called once. Previously, this documentation
recommended all Gio.Initable implementations should be idempotent; that
recommendation was relaxed in GLib 2.54.
If a class explicitly supports being initialized multiple times, it is recommended that the method is idempotent: multiple calls with the same arguments should return the same results. Only the first call initializes the object; further calls return the result of the first call.
One reason why a class might need to support idempotent initialization is if
it is designed to be used via the singleton pattern, with a
GObject.ObjectClass.constructor that sometimes returns an existing instance.
In this pattern, a caller would expect to be able to call g_initable_init()
on the result of g_object_new(), regardless of whether it is in fact a new
instance.
Optionalcancellable: Gio.Cancellableoptional Gio.Cancellable object, null to ignore.
Virtualvfunc_Starts asynchronous initialization of the object implementing the
interface. This must be done before any real use of the object after
initial construction. If the object also implements Gio.Initable you can
optionally call g_initable_init() instead.
This method is intended for language bindings. If writing in C,
g_async_initable_new_async() should typically be used instead.
When the initialization is finished, callback will be called. You can
then call g_async_initable_init_finish() to get the result of the
initialization.
Implementations may also support cancellation. If cancellable is not
null, then initialization can be cancelled by triggering the cancellable
object from another thread. If the operation was cancelled, the error
Gio.IOErrorEnum.CANCELLED will be returned. If cancellable is not null, and
the object doesn't support cancellable initialization, the error
Gio.IOErrorEnum.NOT_SUPPORTED will be returned.
As with Gio.Initable, if the object is not initialized, or initialization
returns with an error, then all operations on the object except
g_object_ref() and g_object_unref() are considered to be invalid, and
have undefined behaviour. They will often fail with g_critical() or
g_warning(), but this must not be relied on.
Callers should not assume that a class which implements Gio.AsyncInitable can
be initialized multiple times; for more information, see g_initable_init().
If a class explicitly supports being initialized multiple times,
implementation requires yielding all subsequent calls to init_async() on the
results of the first call.
For classes that also support the Gio.Initable interface, the default
implementation of this method will run the g_initable_init() function
in a thread, so if you want to support asynchronous initialization via
threads, just implement the Gio.AsyncInitable interface without overriding
any interface methods.

Virtualvfunc_Finishes asynchronous initialization and returns the result.
See g_async_initable_init_async().
Virtualvfunc_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.
Virtualvfunc_the generic setter for all properties of this type. Should be
overridden for every type with properties. If implementations of
set_property don't emit property change notification explicitly, this will
be done implicitly by the type system. However, if the notify signal is
emitted explicitly, the type system will not emit it a second time.
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.

Polkit.Authority is used for checking whether a given subject is authorized to perform a given action. Typically privileged system daemons or suid helpers will use this when handling requests from untrusted clients.
User sessions can register an authentication agent with the authority. This is used for requests from untrusted clients where system policy requires that the user needs to acknowledge (through proving he is the user or the administrator) a given action. See
PolkitAgentListenerandPolkitAgentSessionfor details.
