|
|
* @should_automount: Returns %TRUE if the #GVolume should be automatically mounted.

|
|
* @eject_with_operation: Starts ejecting a #GVolume using a #GMountOperation. Since 2.22.

|
|
* @get_sort_key: Gets a key used for sorting #GVolume instance or %NULL if no such key exists. Since 2.32.
|
|
* @get_symbolic_icon: Gets a symbolic #GIcon for the #GVolume. Since 2.34.
