Glib::RefPtr< Gio::VolumeMonitor > | wrap (GVolumeMonitor* object, bool take_copy=false) |
A Glib::wrap() method for this object. |
Monitors a file or directory for changes.
VolumeMonitor 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.
virtual Gio::VolumeMonitor::~VolumeMonitor | ( | ) | [virtual] |
static Glib::RefPtr<Volume> Gio::VolumeMonitor::adopt_orphan_mount | ( | const Glib::RefPtr< Mount >& | mount | ) | [static] |
This function should be called by any VolumeMonitor implementation when a new Mount object is created that is not associated with a Volume object.
It must be called just before emitting the mount_added signal.
If the return value is not 0
, the caller must associate the returned Volume object with the Mount. 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
Similary, 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 Mount object that needs to be assoicated with the Volume object that represents the volume.
The other is for implementing a VolumeMonitor whose sole purpose is to return Volume objects representing entries in the users "favorite servers" list or similar.
mount | A Mount object to find a parent for. |
Deprecated: 2.20: Instead of using this function, VolumeMonitor implementations should instead create shadow mounts with the URI of the mount they intend to adopt. See the proxy volume monitor in gvfs for an example of this. Also see g_mount_is_shadowed(), g_mount_shadow() and g_mount_unshadow() functions.
