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.
VolumeMonitor is not thread-default-context aware, 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.
Example: Volume monitoring:
public static int main (string[] args) {
MainLoop loop = new MainLoop ();
VolumeMonitor monitor = VolumeMonitor.get ();
//
// The Volume (=logical drive):
//
// Print a list of the volumes on the system:
print ("Volumes:\n");
List<Volume> volumes = monitor.get_volumes ();
foreach (Volume volume in volumes) {
print (" - %s\n", volume.get_name ());
}
// * Signals:
monitor.volume_added.connect ((volume) => {
print ("Volume added: %s\n", volume.get_name ());
});
monitor.volume_changed.connect ((volume) => {
print ("Volume changed: %s\n", volume.get_name ());
});
monitor.volume_removed.connect ((volume) => {
print ("Volume removed: %s\n", volume.get_name ());
});
//
// Drive: (connected hardware)
//
// Print a list of drives connected to the system:
print ("Drives:\n");
List<Drive> drives = monitor.get_connected_drives ();
foreach (Drive drive in drives) {
print (" - %s\n", drive.get_name ());
}
// * Signals:
monitor.drive_changed.connect ((drive) => {
print ("Drive changed: %s\n", drive.get_name ());
});
monitor.drive_connected.connect ((drive) => {
print ("Drive connected: %s\n", drive.get_name ());
});
monitor.drive_disconnected.connect ((drive) => {
print ("Drive disconnected: %s\n", drive.get_name ());
});
monitor.drive_eject_button.connect ((drive) => {
print ("Drive eject-button: %s\n", drive.get_name ());
});
monitor.drive_stop_button.connect ((drive) => {
print ("Drive stop-button:%s\n", drive.get_name ());
});
//
// Mount: (user-visible mounted filesystem that you can access)
//
// Print a list of the mounts on the system:
List<Mount> mounts = monitor.get_mounts ();
foreach (Mount mount in mounts) {
print (" - %s\n", mount.get_name ());
}
// * Signals:
monitor.mount_added.connect ((mount) => {
print ("Mount added: %s\n", mount.get_name ());
});
monitor.mount_changed.connect ((mount) => {
print ("Mount changed: %s\n", mount.get_name ());
});
monitor.mount_pre_unmount.connect ((mount) => {
print ("Mount pre-unmount: %s\n", mount.get_name ());
});
monitor.mount_removed.connect ((mount) => {
print ("Mount removed: %s\n", mount.get_name ());
});
loop.run ();
return 0;
