  50  * @has_media: Returns %TRUE if the #GDrive has media inserted.
  51  * @is_media_check_automatic: Returns %TRUE if the #GDrive is capabable of automatically detecting media changes.
  52  * @can_poll_for_media: Returns %TRUE if the #GDrive is capable of manually polling for media change.
  53  * @can_eject: Returns %TRUE if the #GDrive can eject media.
  54  * @eject: Ejects a #GDrive.
  55  * @eject_finish: Finishes an eject operation.
  56  * @poll_for_media: Poll for media insertion/removal on a #GDrive.
  57  * @poll_for_media_finish: Finishes a media poll operation.
  58  * @get_identifier: Returns the identifier of the given kind, or %NULL if
  59  *    the #GDrive doesn't have one.
  60  * @enumerate_identifiers: Returns an array strings listing the kinds
  61  *    of identifiers which the #GDrive has.
  62  * @get_start_stop_type: Gets a #GDriveStartStopType with details about starting/stopping the drive. Since 2.22.
  63  * @can_stop: Returns %TRUE if a #GDrive can be stopped. Since 2.22.

  69  * @start_finish: Finishes a start operation. Since 2.22.
  70  * @stop_button: Signal emitted when the physical stop button (if any) of a drive have been pressed. Since 2.22.
  71  * @eject_with_operation: Starts ejecting a #GDrive using a #GMountOperation. Since 2.22.
  72  * @eject_with_operation_finish: Finishes an eject operation using a #GMountOperation. Since 2.22.
  73  * @get_sort_key: Gets a key used for sorting #GDrive instances or %NULL if no such key exists. Since 2.32.
  74  * @get_symbolic_icon: Returns a symbolic #GIcon for the given #GDrive. Since 2.34.
