The lock/unlock frame, an example of which is to the right, can be found near the bottom of any CLEO application that attaches to an YGOR manager. The frame provides security for a manager. It:
Data security is provided by the CLEO Gateway data base system. Only the operator will be able to grant control permission to a user. If you do not have permissions to control a manager you still have the ability to monitor the manager; you only lose the ability to control the device. Unlocking a locked application:When you start an application that has a lock/unlock frame, the screen is generated with the lock on as illustrated in this example from part of the Holography application. You'll notice that all the widgets you might want to control are disabled and have a "misty rose" colored background (e.g., the Attenuator spinboxes). Whenever you quit or close a screen and then reopen it, the lock is turned back on (for safety reasons). To unlock the application so that you can control the device, click on the Locked button. If you have permission to control the device, the screen will unlock for you otherwise you'll get an error message.
AutoPrepare and PrepareThe lock/unlock frame also has an AutoPrepare check button and a Prepare button. (For some applications, the concept of 'Prepare'ing a manager is not applicable and these widgets will be missing from those screens. (See YGOR Fundamentals). In most cases, the application's default is to be in the AutoPrepare mode.
