Struct gio::VolumeMonitor

source ·
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.
