Arrow Return.png Shutter  

The workflow of Shutter is a simple 3-step process:

  1. Add events that are to be monitored, and
  2. Add actions that are to be executed when the specified events occur.
  3. Start monitoring for the specified events.

The details are as follows:

Step 1: Load Events

Events are usually based on periodic checking of a system state, execution state of a process, or system time.

Note that this step only loads the events; Shutter will not start monitoring for the event till you press the ShutterStartButton.png button (see Step 3).

Step 2: Load Actions

Actions are executed one by one, from top to bottom.

You can add as many actions as you want, but please be aware of the following factors:

  • Each action can affect the execution of the other actions listed below it.
    To avoid that, you may have to change the order of the Actions by moving them up/down.
  • Some of these actions are terminal: They close Shutter, log out the Windows user or shut down the PC. For example: the Shutdown action.
    Therefore, such Actions must be placed at the very end of the Actions stack. Otherwise the actions listed below them will never be executed!

Step 3: Start monitoring

Press the ShutterStartButton.png button. Shutter starts monitoring for the events. The button changes to ShutterStopButton.png. Press it if you want to stop Shutter in an emergency.

  • Shutter also has a ShutterNowButton.png button, which starts all actions without waiting for triggering the event-set.
This is useful to check how the specified actions would actually work.
