[maemo-developers] How to catch “lock screen event”?

[From: Xin Zhang]

Hi all,

I'm developing a game for n900 using SDL. How do I catch system events (like lock screen switch turned on/off, screen gets locked automatically, or incoming call during game play)? 

Right now when the game is running, I could not catch the system events (like lock screen switch turned on/off, screen gets locked automatically, or incoming call during game play). Therefore, the game is still active running even screen is locked. I hope I can catch these system events and make the game paused. Could anyone give me some direction in fixing the problem? 

I've posted a thread in [http://talk.maemo.org/showthread.php?t=59238]. Many thanks!

Best regards,
Zhang Xin
