This class is used for setting the unlock string (also called "license string" or "password") programmatically. Master passwords and encrypted passwords must be specified via this mechanism.

If your application uses any of the Open Inventor extensions (e.g., MeshViz, VolumeViz, etc.), you will need to specify the necessary license strings using a colon-separated list or a newline-separated list. For encrypted passwords, you must use a newline-separated list. (Since SoLockManager stores only a single string, it would not work to make multiple calls, each specifying a single license string; each call would overwrite the previously specified value.)

You must set the unlock string before any other call to OpenInventor framework. This means the password string should typically be specified in your application's main.
