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.

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 nil, 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.
