Detect User Activity in Mac OS X from SWT/RCP [message #715221]

I want to create a time/task-tracking type application (a planned opensource project) using either SWT or Eclipse RCP, and need to determine the best route to take to detect user activity/inactivity on the different native platforms, starting with Mac OS X.

Worst case one probably have to go the JNI and native code per platform route, but I would like to find out if there is a easier route, perhaps some existing libs our there or some support for this in SWT that I have not discovered yet.

I basically would like to keep track of when a user is actively using the computer, and when not so the timers could be paused/resumed.

Any help would be appreciated.

SWT sends UI events while your app has focus. If you want to be made
aware of UI events (or their absence) while a non-SWT app has focus then
you'll need some OS-specific code, as SWT doesn't provide
platform-common API that would enable this.

There was a previous request for this with some discussion at
https://bugs.eclipse.org/bugs/show_bug.cgi?id=37061 .

Thanks Grant, I expected your answer, just wanted to confirm.

So the way forward seems to be some native code and then using JNI to interact with it. Perhaps I could extend it a bit on the SWT native-to-java level.
Now just to find the time to do this...
