Interface (GI Interface)

Gio-2.0GioMount

The Gio.Mount interface represents a user-visible mount, such as a mounted file system.

Gio.Mount is a ‘mounted’ filesystem that you can access. Mounted is in quotes because it’s not the same as a UNIX mount, it might be a GVFS mount, but you can still access the files on it if you use GIO.

A Gio.Mount might be associated with a Gio.Volume (such as a USB flash drive) which hosts it.

Unmounting a Gio.Mount instance is an asynchronous operation. For more information about asynchronous operations, see Gio.AsyncResult and Gio.Task. To unmount a Gio.Mount instance, first call Gio.Mount.unmount_with_operation with (at least) the Gio.Mount instance and a Gio.AsyncReadyCallback. The callback will be fired when the operation has resolved (either with success or failure), and a Gio.AsyncResult structure will be passed to the callback. That callback should then call Gio.Mount.unmount_with_operation_finish with the Gio.Mount and the Gio.AsyncResult data to see if the operation was completed successfully. If an error is present when Gio.Mount.unmount_with_operation_finish is called, then it will be filled with any error information.

Note, when porting from GnomeVFS, Gio.Mount is the moral equivalent of GnomeVFSVolume.

Properties - Inherited from GObject

Compile-time signal type information.

This instance property is generated only for TypeScript type checking. It is not defined at runtime and should not be accessed in JS code.

Methods

  • Checks if mount can be ejected.

    Returns boolean

    true if the mount can be ejected.

  • Checks if mount can be unmounted.

    Returns boolean

    true if the mount can be unmounted.

  • Finishes ejecting a mount. If any errors occurred during the operation, error will be set to contain the errors and false will be returned.

    Parameters

    Returns boolean

    true if the mount was successfully ejected. false otherwise.

  • Finishes ejecting a mount. If any errors occurred during the operation, error will be set to contain the errors and false will be returned.

    Parameters

    Returns boolean

    true if the mount was successfully ejected. false otherwise.

  • Gets the default location of mount. The default location of the given mount is a path that reflects the main entry point for the user (e.g. the home directory, or the root of the volume).

    Returns Gio.File

    a Gio.File. The returned object should be unreffed with g_object_unref() when no longer needed.

  • Gets the drive for the mount.

    This is a convenience method for getting the Gio.Volume and then using that object to get the Gio.Drive.

    Returns Gio.Drive

    a Gio.Drive or null if mount is not associated with a volume or a drive. The returned object should be unreffed with g_object_unref() when no longer needed.

  • Gets the name of mount.

    Returns string

    the name for the given mount. The returned string should be freed with g_free() when no longer needed.

  • Gets the sort key for mount, if any.

    Returns string

    Sorting key for mount or null if no such key is available.

  • Gets the UUID for the mount. The reference is typically based on the file system UUID for the mount in question and should be considered an opaque string. Returns null if there is no UUID available.

    Returns string

    the UUID for mount or null if no UUID can be computed. The returned string should be freed with g_free() when no longer needed.

  • Tries to guess the type of content stored on mount. Returns one or more textual identifiers of well-known content types (typically prefixed with "x-content/"), e.g. x-content/image-dcf for camera memory cards. See the shared-mime-info specification for more on x-content types.

    This is an asynchronous operation (see g_mount_guess_content_type_sync() for the synchronous version), and is finished by calling g_mount_guess_content_type_finish() with the mount and Gio.AsyncResult data returned in the callback.

    Parameters

    • force_rescan: boolean

      Whether to force a rescan of the content. Otherwise a cached result will be used if available

    • Optionalcancellable: Gio.Cancellable

      optional Gio.Cancellable object, null to ignore

    Returns Promise<string[]>

  • Tries to guess the type of content stored on mount. Returns one or more textual identifiers of well-known content types (typically prefixed with "x-content/"), e.g. x-content/image-dcf for camera memory cards. See the shared-mime-info specification for more on x-content types.

    This is an asynchronous operation (see g_mount_guess_content_type_sync() for the synchronous version), and is finished by calling g_mount_guess_content_type_finish() with the mount and Gio.AsyncResult data returned in the callback.

    Parameters

    Returns void

  • Tries to guess the type of content stored on mount. Returns one or more textual identifiers of well-known content types (typically prefixed with "x-content/"), e.g. x-content/image-dcf for camera memory cards. See the shared-mime-info specification for more on x-content types.

    This is an asynchronous operation (see g_mount_guess_content_type_sync() for the synchronous version), and is finished by calling g_mount_guess_content_type_finish() with the mount and Gio.AsyncResult data returned in the callback.

    Parameters

    Returns void | Promise<string[]>

  • Finishes guessing content types of mount. If any errors occurred during the operation, error will be set to contain the errors and false will be returned. In particular, you may get an Gio.IOErrorEnum.NOT_SUPPORTED if the mount does not support content guessing.

    Parameters

    Returns string[]

    a null-terminated array of content types or null on error. Caller should free this array with g_strfreev() when done with it.

  • Tries to guess the type of content stored on mount. Returns one or more textual identifiers of well-known content types (typically prefixed with "x-content/"), e.g. x-content/image-dcf for camera memory cards. See the shared-mime-info specification for more on x-content types.

    This is a synchronous operation and as such may block doing IO; see g_mount_guess_content_type() for the asynchronous version.

    Parameters

    • force_rescan: boolean

      Whether to force a rescan of the content. Otherwise a cached result will be used if available

    • Optionalcancellable: Gio.Cancellable

      optional Gio.Cancellable object, null to ignore

    Returns string[]

    a null-terminated array of content types or null on error. Caller should free this array with g_strfreev() when done with it.

  • Determines if mount is shadowed. Applications or libraries should avoid displaying mount in the user interface if it is shadowed.

    A mount is said to be shadowed if there exists one or more user visible objects (currently Gio.Mount objects) with a root that is inside the root of mount.

    One application of shadow mounts is when exposing a single file system that is used to address several logical volumes. In this situation, a Gio.VolumeMonitor implementation would create two Gio.Volume objects (for example, one for the camera functionality of the device and one for a SD card reader on the device) with activation URIs gphoto2://[usb:001,002]/store1/ and gphoto2://[usb:001,002]/store2/. When the underlying mount (with root gphoto2://[usb:001,002]/) is mounted, said Gio.VolumeMonitor implementation would create two Gio.Mount objects (each with their root matching the corresponding volume activation root) that would shadow the original mount.

    The proxy monitor in GVfs 2.26 and later, automatically creates and manage shadow mounts (and shadows the underlying mount) if the activation root on a Gio.Volume is set.

    Returns boolean

    true if mount is shadowed.

  • Remounts a mount. This is an asynchronous operation, and is finished by calling g_mount_remount_finish() with the mount and GAsyncResults data returned in the callback.

    Remounting is useful when some setting affecting the operation of the volume has been changed, as these may need a remount to take affect. While this is semantically equivalent with unmounting and then remounting not all backends might need to actually be unmounted.

    Parameters

    Returns Promise<boolean>

  • Remounts a mount. This is an asynchronous operation, and is finished by calling g_mount_remount_finish() with the mount and GAsyncResults data returned in the callback.

    Remounting is useful when some setting affecting the operation of the volume has been changed, as these may need a remount to take affect. While this is semantically equivalent with unmounting and then remounting not all backends might need to actually be unmounted.

    Parameters

    Returns void

  • Remounts a mount. This is an asynchronous operation, and is finished by calling g_mount_remount_finish() with the mount and GAsyncResults data returned in the callback.

    Remounting is useful when some setting affecting the operation of the volume has been changed, as these may need a remount to take affect. While this is semantically equivalent with unmounting and then remounting not all backends might need to actually be unmounted.

    Parameters

    Returns void | Promise<boolean>

  • Finishes remounting a mount. If any errors occurred during the operation, error will be set to contain the errors and false will be returned.

    Parameters

    Returns boolean

    true if the mount was successfully remounted. false otherwise.

  • Increments the shadow count on mount. Usually used by Gio.VolumeMonitor implementations when creating a shadow mount for mount, see g_mount_is_shadowed() for more information. The caller will need to emit the Gio.Mount.SignalSignatures.changed | Gio.Mount::changed signal on mount manually.

    Returns void

  • Finishes unmounting a mount. If any errors occurred during the operation, error will be set to contain the errors and false will be returned.

    Parameters

    Returns boolean

    true if the mount was successfully unmounted. false otherwise.

  • Finishes unmounting a mount. If any errors occurred during the operation, error will be set to contain the errors and false will be returned.

    Parameters

    Returns boolean

    true if the mount was successfully unmounted. false otherwise.

  • Decrements the shadow count on mount. Usually used by Gio.VolumeMonitor implementations when destroying a shadow mount for mount, see g_mount_is_shadowed() for more information. The caller will need to emit the Gio.Mount.SignalSignatures.changed | Gio.Mount::changed signal on mount manually.

    Returns void

Methods - Inherited from GObject

  • 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.

    A GObject.Object can have multiple bindings.

    Parameters

    Returns GObject.Binding

    the GObject.Binding instance representing the binding between the two GObject.Object instances. The binding is released whenever the GObject.Binding reference count reaches zero.

  • Complete version of g_object_bind_property().

    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.

    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 for each transformation function, please use g_object_bind_property_with_closures() instead.

    Parameters

    • source_property: string

      the property on source to bind

    • target: GObject.Object

      the target GObject.Object

    • target_property: string

      the property on target to bind

    • flags: GObject.BindingFlags

      flags to pass to GObject.Binding

    • Optionaltransform_to: BindingTransformFunc

      the transformation function from the source to the target, or null to use the default

    • Optionaltransform_from: BindingTransformFunc

      the transformation function from the target to the source, or null to use the default

    • Optionalnotify: DestroyNotify

      a function to call when disposing the binding, to free resources used by the transformation functions, or null if not required

    Returns GObject.Binding

    the GObject.Binding instance representing the binding between the two GObject.Object instances. The binding is released whenever the GObject.Binding reference count reaches zero.

  • 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.

    Parameters

    Returns GObject.Binding

    the GObject.Binding instance representing the binding between the two GObject.Object instances. The binding is released whenever the GObject.Binding reference count reaches zero.

  • Disconnects a handler from an instance so it will not be called during any future or currently ongoing emissions of the signal it has been connected to.

    Parameters

    • id: number

      Handler ID of the handler to be disconnected

    Returns void

  • This function is intended for GObject.Object implementations to re-enforce a floating 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().

    Returns void

  • 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.

    Returns void

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

    Parameters

    • key: string

      name of the key for that association

    Returns any

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

  • Gets a property of an object.

    The value can be:

    • an empty GObject.Value initialized by G_VALUE_INIT, which will be automatically initialized with the expected type of the property (since GLib 2.60)
    • a GObject.Value initialized with the expected type of the property
    • a GObject.Value initialized with a type to which the expected type of the property can be transformed

    In general, a copy is made of the property contents and the caller is responsible for freeing the memory by calling GObject.Value.unset.

    Note that GObject.Object.get_property is really intended for language bindings, GObject.Object.get is much more convenient for C programming.

    Parameters

    • property_name: string

      The name of the property to get

    • value: any

      Return location for the property value. Can be an empty GObject.Value initialized by G_VALUE_INIT (auto-initialized with expected type since GLib 2.60), a GObject.Value initialized with the expected property type, or a GObject.Value initialized with a transformable type

    Returns any

  • This function gets back user data pointers stored via g_object_set_qdata().

    Parameters

    • quark: number

      A GLib.Quark, naming the user data pointer

    Returns any

    The user data pointer set, or null

  • Gets n_properties properties for an object. Obtained properties will be set to values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.

    Parameters

    • names: string[]

      the names of each property to get

    • values: any[]

      the values of each property to get

    Returns void

  • 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.

    Parameters

    • property_name: string

      the name of a property installed on the class of object.

    Returns void

  • 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.:

    Parameters

    Returns void

  • 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.

    Returns GObject.Object

    the same object

  • Increase the reference count of object, and possibly remove the floating 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().

    Returns GObject.Object

    object

  • Releases all references to other objects. This can be used to break reference cycles.

    This function should only be called from object system implementations.

    Returns void

  • Sets multiple properties of an object at once. The properties argument should be a dictionary mapping property names to values.

    Parameters

    • properties: { [key: string]: any }

      Object containing the properties to set

    Returns void

  • 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.

    Parameters

    • key: string

      name of the key

    • Optionaldata: any

      data to associate with that key

    Returns void

  • Sets a property on an object.

    Parameters

    • property_name: string

      The name of the property to set

    • value: any

      The value to set the property to

    Returns void

  • Remove a specified datum from the object's data associations, without invoking the association's destroy handler.

    Parameters

    • key: string

      name of the key

    Returns any

    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().

    Parameters

    • quark: number

      A GLib.Quark, naming the user data pointer

    Returns any

    The user data pointer set, or null

  • Stops a signal's emission by the given signal name. This will prevent the default handler and any subsequent signal handlers from being invoked.

    Parameters

    • detailedName: string

      Name of the signal to stop emission of

    Returns void

  • 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.

    Returns void

  • 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.

    Returns void

  • 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.

    Returns void

  • 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.

    Returns void

  • instance finalization function, should finish the finalization of the instance begun in dispose and chain up to the finalize method of the parent class.

    Returns void

  • 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.

    Parameters

    Returns void

  • 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.

    Parameters

    Returns void

  • 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.

    Parameters

    Returns void

Methods - Inherited from Gio.Mount.Interface

  • Gets the UUID for the mount. The reference is typically based on the file system UUID for the mount in question and should be considered an opaque string. Returns null if there is no UUID available.

    Returns string

  • Tries to guess the type of content stored on mount. Returns one or more textual identifiers of well-known content types (typically prefixed with "x-content/"), e.g. x-content/image-dcf for camera memory cards. See the shared-mime-info specification for more on x-content types.

    This is an asynchronous operation (see g_mount_guess_content_type_sync() for the synchronous version), and is finished by calling g_mount_guess_content_type_finish() with the mount and Gio.AsyncResult data returned in the callback.

    Parameters

    Returns void

  • Tries to guess the type of content stored on mount. Returns one or more textual identifiers of well-known content types (typically prefixed with "x-content/"), e.g. x-content/image-dcf for camera memory cards. See the shared-mime-info specification for more on x-content types.

    This is a synchronous operation and as such may block doing IO; see g_mount_guess_content_type() for the asynchronous version.

    Parameters

    • force_rescan: boolean

      Whether to force a rescan of the content. Otherwise a cached result will be used if available

    • Optionalcancellable: Gio.Cancellable

      optional Gio.Cancellable object, null to ignore

    Returns string[]

  • The ::pre-unmount signal that is emitted when the Gio.Mount will soon be emitted. If the recipient is somehow holding the mount open by keeping an open file on it it should close the file.

    Returns void

  • The unmounted signal that is emitted when the Gio.Mount have been unmounted. If the recipient is holding references to the object they should release them so the object can be finalized.

    Returns void
