class Gio::VolumeMonitor

Overview

#GVolumeMonitor is for listing the user interesting devices and volumes on the computer. In other words, what a file selector or file manager would show in a sidebar.

#GVolumeMonitor is not [thread-default-context aware][g-main-context-push-thread-default], and so should not be used other than from the main thread, with no thread-default-context active.

In order to receive updates about volumes and mounts monitored through GVFS, a main loop must be running.

def self.new #

Initialize a new VolumeMonitor.


Class Method Detail

def self.adopt_orphan_mount(mount : Gio::Mount) : Gio::Volume #

This function should be called by any #GVolumeMonitor implementation when a new #GMount object is created that is not associated with a #GVolume object. It must be called just before emitting the @mount_added signal.

If the return value is not %NULL, the caller must associate the returned #GVolume object with the #GMount. This involves returning it in its g_mount_get_volume() implementation. The caller must also listen for the "removed" signal on the returned object and give up its reference when handling that signal

Similarly, if implementing g_volume_monitor_adopt_orphan_mount(), the implementor must take a reference to @mount and return it in its g_volume_get_mount() implemented. Also, the implementor must listen for the "unmounted" signal on @mount and give up its reference upon handling that signal.

There are two main use cases for this function.

One is when implementing a user space file system driver that reads blocks of a block device that is already represented by the native volume monitor (for example a CD Audio file system driver). Such a driver will generate its own #GMount object that needs to be associated with the #GVolume object that represents the volume.

The other is for implementing a #GVolumeMonitor whose sole purpose is to return #GVolume objects representing entries in the users "favorite servers" list or similar.


def self.g_type : UInt64 #

Returns the type id (GType) registered in GLib type system.


def self.get : Gio::VolumeMonitor #

Gets the volume monitor used by gio.


Instance Method Detail

def connected_drives : GLib::List #

Gets a list of drives connected to the system.

The returned list should be freed with g_list_free(), after its elements have been unreffed with g_object_unref().


def drive_changed_signal #

def drive_connected_signal #

def drive_disconnected_signal #

def drive_eject_button_signal #

def drive_stop_button_signal #

def mount_added_signal #

def mount_changed_signal #

def mount_for_uuid(uuid : String) : Gio::Mount? #

Finds a #GMount object by its UUID (see g_mount_get_uuid())


def mount_pre_unmount_signal #

def mount_removed_signal #

def mounts : GLib::List #

Gets a list of the mounts on the system.

The returned list should be freed with g_list_free(), after its elements have been unreffed with g_object_unref().


def volume_added_signal #

def volume_changed_signal #

def volume_for_uuid(uuid : String) : Gio::Volume? #

Finds a #GVolume object by its UUID (see g_volume_get_uuid())


def volume_removed_signal #

def volumes : GLib::List #

Gets a list of the volumes on the system.

The returned list should be freed with g_list_free(), after its elements have been unreffed with g_object_unref().
