Hi Xing,
Are you sure that all applications for your daemon would want polling to
stop when they are in the background? Can we not imagine an application
that runs in background (e.g., as an icon) and displays a pop-up message
when some sensor event is detected? If so, instead of the daemon deciding
how all application(s) must behave, why not allow each application to tell
the daemon when to stop polling (or what polling rate is required)? This
seems possible since there is already a connection between the application
and the daemon.

My application is a sensor daemon supplying data to application, e.g.
accelerometer data.
If an application connects to my daemon, the daemon will poll driver in a
high sample rate which obviously kills power.
so if I could know which application is viewable to user, I could stop
polling since sensor awareness application is running at background
My thought is to write a context provider of window manager to provide
such feature.
Thank you your suggestion. I will take a look of Libwnck first.

Libwnck may be worth a look, but I don't know if it's available in all
versions... If you explain what you want to achieve (and in what
context), you might get better suggestions.
HTH,
