GtkMountOperation is an implementation of GMountOperation.
The functions and objects described here make working with GTK and GIO more convenient.
GtkMountOperation is needed when mounting volumes: It is an implementation of GMountOperation that can be used with GIO functions for mounting volumes such as g_file_mount_enclosing_volume(), g_file_mount_mountable(), g_volume_mount(), g_mount_unmount_with_operation() and others.
When necessary, GtkMountOperation shows dialogs to let the user enter passwords, ask questions or show processes blocking unmount.
