In my application, I'd like do something when a user has been inactive/idle for a while - in this case, I want the application to actually lock and request a pincode or password to let the user back in again.
This kept me busy for quite a while, just to find out that there is a hidden gem in Lazarus Pascal that does it all ...
Simply use TIdleTime, set the proper Interval (in milliseconds) and set Enabled:=TRUE and AutoEnabled:=TRUE.
After the user (keyboard and mouse) has been idle for the given time then the OnTimer event will fire.
Note: I have the impression that it was not specifically designed for this purpose, but it works.
