pub struct VolumeMonitor { /* private fields */ }
Expand description
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 (see
[glib::MainContext::push_thread_default()
][crate::glib::MainContext::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.
§Signals
§drive-changed
Emitted when a drive changes.
§drive-connected
Emitted when a drive is connected to the system.
§drive-disconnected
Emitted when a drive is disconnected from the system.
§drive-eject-button
Emitted when the eject button is pressed on @drive.
§drive-stop-button
Emitted when the stop button is pressed on @drive.
§mount-added
Emitted when a mount is added.
§mount-changed
Emitted when a mount changes.
§mount-pre-unmount
May be emitted when a mount is about to be removed.
This signal depends on the backend and is only emitted if GIO was used to unmount.
§mount-removed
Emitted when a mount is removed.
§volume-added
Emitted when a mountable volume is added to the system.
§volume-changed
Emitted when mountable volume is changed.
§volume-removed
Emitted when a mountable volume is removed from the system.
§Implements
VolumeMonitorExt
, [trait@glib::ObjectExt

GLib type: GObject with reference counted clone semantics.
Implementations§
Source§impl VolumeMonitor
impl VolumeMonitor
pub const NONE: Option<&'static VolumeMonitor> = None
Sourcepub fn get() -> VolumeMonitor
pub fn get() -> VolumeMonitor
Gets the volume monitor used by gio.
§Returns
a reference to the #GVolumeMonitor used by gio. Call g_object_unref() when done with it.
