Is there anyway to detect user inactivity in java?

Question

I am writing a desktop application in which I want to perform an operation if user doesn't use the computer for X number of minutes. Just like auto idle in MSN messager or skype. Any hints?

Answer 1

I found https://code.google.com/p/fiat-lux/source/browse/Fiat+Lux/src/fiatlux/os/time/ that served my purpose.

Thanks

Answer 2

you need to:

• listen for events at the application level
• track the time interval between these events

read here this article. you have the code under InactivityListener.java

And there is even a similar thread: How to detect inactivity/idle time since last keypressed on j2me

Answer 3

You can use a background thread that basically only sleeps idle or a quartz task if you are not already using any timer/job scheduler library.
