Shutter:Events

Below is a list of all available events.

Remember that Shutter is often used with a set of multiple events (rather than a single event); and these events have a  pre-defined relationship between them.

Event	Definition	Typical uses
Countdown	User enters some amount of time (in terms of Hours:Miutes:seconds).Shutter counts down to zero. This Event is considered "triggered" when the timer reaches zero. This is the only event that is controlled by Shutter: All other events are external to Shutter, and Shutter only monitors them.	If you suffer from RSI, set timer to take a break every few minutes and exercise your hands, shoulder and neck. Use Shutter as a count-down timer clock (to give alarm at the end of specified time). Play a pre-recorded sound every few minutes (to calm down a baby or a pet).
On Time	Event is triggered when the current time (as displayed in the system tray) reaches the specified time. Note: Prior to v3.00 Beta 35, the On Time event worked in the same manner as the Countdown event, counting down the initial time difference between the current time and the target time. However, that method prevented the On Time event from working correctly if the system time was changed or if Windows entered a suspended state.	Launch an application (e.g. a downloader) at certain time. Share your PC on LAN till a particular time, and then turn it off at certain time.
Winamp Stops	Event periodically checks the playback state of Winamp. The event is triggered once it is detected that application is no longer playing the media. Note: Winamp Messaging API is used to achieve this.	When the WinAmp playlist is over, pause for a specified time period and then play another playlist, or hibernate the PC.
Low CPU Usage	Periodically check the processor usage and trigger event when the usage stays below the specified mark for the specified amount of time.	Launch a CPU-intensive application (e.g. Blender rendering) to get the benefit of full CPU power.
User Inactive	Track the time of user's last mouse and keyboard activity. Trigger event when user is inactive for the specified period of time.	Play WinAmp when no one is using the PC (turn the PC into entertainment center). Launch a task that can otherwise slow down the PC.
Battery Low	Monitor power battery level and trigger event when level drops below specified level.	Take backup of critical data. Close specified applications gracefully. Remind the user to plug in the laptop charger.
Window Closes	Monitor opened windows for the specified title match. Event is triggered when specified title does not match any of the opened windows. The name is NOT case-sensitive. You can specify wildcards to find a partial match. For example, *Firefox* If you do not use wildcards, Shutter will look for an exact match (if the actual Window name has more characters compared to the specified string, Shutter will treat it as "not matching"). Note: Be careful when specifying the window name: The text should match with what you see in the Title Bar of the application (the top bar of the application's window). Sometimes the Title Bar shows the file that is opened in the application, instead of the application's name.	Warn the user that the desired application has stopped running. Launch the process only if the application is not running already (to avoid multiple instances running simultaneously)
Process Stops	Monitor all processes that match the specified filename. Event is triggered when the specified filename is not found in the list of executing processes.	Warn the user that the process has stopped. Launch the next process in sequence.
Ping Stops	Ping the specified host and trigger when host is not responding for the specified period of time. Useful for monitoring availability of network services.	Warn the user that the reote PC is not communicating any more (either bad link or crash).
File Size Limit	Periodically check the size of the specified file and trigger event when file reaches the specified size. Size "0" can be used to check whether file exists or not.	Take a backup of the file. Warn the user that the file size has reached the limit.
