Class Gio.Permission

Import line:	Gio = imports.gi.Gio;
GIR File:	Gio-2.0.gir
C documentation:	GPermission
Class :	Permission
Extends:	GObject.Object

A GPermission represents the status of the caller's permission to
perform a certain action.
You can query if the action is currently allowed and if it is
possible to acquire the permission so that the action will be allowed
in the future.
There is also an API to actually acquire the permission and one to
release it.
As an example, a GPermission might represent the ability for the
user to write to a GSettings object. This GPermission object could
then be used to decide if it is appropriate to show a "Click here to
unlock" button in a dialog and to provide the mechanism to invoke
when that button is clicked.

Properties
Properties		Defined By
	allowed : gboolean read only TRUE if the caller currently has permission to perform the action that TRUE if the caller currently has permission to perform the action that	Gio.Permission
	can_acquire : gboolean read only TRUE if it is generally possible to acquire the permission by calling g_permission_acquire(). TRUE if it is generally possible to acquire the permission by calling g_permission_acquire().	Gio.Permission
	can_release : gboolean read only TRUE if it is generally possible to release the permission by calling g_permission_release(). TRUE if it is generally possible to release the permission by calling g_permission_release().	Gio.Permission
	parent_instance : GObject.Object read only	Gio.Permission
	priv : Gio.PermissionPrivate read only	Gio.Permission

Methods / Constructors
Method / Constructor		Defined By
	new Gio.Permission (Object *properties) Create a new Gio.Permission Create a new Gio.Permission Parameters: Object properties*
	acquire (Cancellable *cancellable) : gboolean Attempts to acquire the permission represented by permission. Attempts to acquire the permission represented by permission. The precise method by which this happens depends on the permission and the underlying authentication mechanism. A simple example is that a dialog may appear asking the user to enter their password. You should check with g_permission_get_can_acquire() before calling this function. If the permission is acquired then TRUE* is returned. Otherwise, FALSE is returned and error is set appropriately. This call is blocking, likely for a very long time (in the case that user interaction is required). See g_permission_acquire_async() for the non-blocking version. Parameters: Gio.Cancellable cancellable a GCancellable, or NULL Returns: gboolean TRUE if the permission was successfully acquired	Gio.Permission
	acquire_async (Cancellable *cancellable, Function callback, void *user_data) : none Attempts to acquire the permission represented by permission. Attempts to acquire the permission represented by permission. This is the first half of the asynchronous version of g_permission_acquire(). Parameters: Gio.Cancellable cancellable* a GCancellable, or NULL Function (Object *source_object, AsyncResult res, void *user_data) : none Required (not null) the GAsyncReadyCallback* to call when done void* user_data Required (not null) the user data to pass to callback Returns: none	Gio.Permission
	acquire_finish (AsyncResult *result) : gboolean Collects the result of attempting to acquire the permission represented by permission. Collects the result of attempting to acquire the permission represented by permission. This is the second half of the asynchronous version of g_permission_acquire(). Parameters: Gio.AsyncResult result* Required (not null) the GAsyncResult given to the GAsyncReadyCallback Returns: gboolean TRUE if the permission was successfully acquired	Gio.Permission
	get_allowed () : gboolean Gets the value of the 'allowed' property. Gets the value of the 'allowed' property. This property is TRUE if the caller currently has permission to perform the action that Returns: gboolean the value of the 'allowed' property	Gio.Permission
	get_can_acquire () : gboolean Gets the value of the 'can-acquire' property. Gets the value of the 'can-acquire' property. This property is TRUE if it is generally possible to acquire the permission by calling g_permission_acquire(). Returns: gboolean the value of the 'can-acquire' property	Gio.Permission
	get_can_release () : gboolean Gets the value of the 'can-release' property. Gets the value of the 'can-release' property. This property is TRUE if it is generally possible to release the permission by calling g_permission_release(). Returns: gboolean the value of the 'can-release' property	Gio.Permission
	impl_update (gboolean *allowed, gboolean can_acquire, gboolean can_release) : none This function is called by the GPermission* implementation to update the properties of the permission. This function is called by the GPermission implementation to update the properties of the permission. You should never call this function except from a GPermission implementation. GObject notify signals are generated, as appropriate. Parameters: gboolean allowed Required (not null) the new value for the 'allowed' property gboolean can_acquire Required (not null) the new value for the 'can-acquire' property gboolean can_release Required (not null) the new value for the 'can-release' property Returns: none	Gio.Permission
	release (Cancellable *cancellable) : gboolean Attempts to release the permission represented by permission. Attempts to release the permission represented by permission. The precise method by which this happens depends on the permission and the underlying authentication mechanism. In most cases the permission will be dropped immediately without further action. You should check with g_permission_get_can_release() before calling this function. If the permission is released then TRUE* is returned. Otherwise, FALSE is returned and error is set appropriately. This call is blocking, likely for a very long time (in the case that user interaction is required). See g_permission_release_async() for the non-blocking version. Parameters: Gio.Cancellable cancellable a GCancellable, or NULL Returns: gboolean TRUE if the permission was successfully released	Gio.Permission
	release_async (Cancellable *cancellable, Function callback, void *user_data) : none Attempts to release the permission represented by permission. Attempts to release the permission represented by permission. This is the first half of the asynchronous version of g_permission_release(). Parameters: Gio.Cancellable cancellable* a GCancellable, or NULL Function (Object *source_object, AsyncResult res, void *user_data) : none Required (not null) the GAsyncReadyCallback* to call when done void* user_data Required (not null) the user data to pass to callback Returns: none	Gio.Permission
	release_finish (AsyncResult *result) : gboolean Collects the result of attempting to release the permission represented by permission. Collects the result of attempting to release the permission represented by permission. This is the second half of the asynchronous version of g_permission_release(). Parameters: Gio.AsyncResult result* Required (not null) the GAsyncResult given to the GAsyncReadyCallback Returns: gboolean TRUE if the permission was successfully released	Gio.Permission
