[Help] How to catch "Lock screen" event in SDL event loop?

[zhx]

Hi all,

I'm developing a game for n900. However, I think the question is general enough to be placed in the Applications category.

How do I catch system events (like lock screen switch turned on/off, screen gets locked automatically, or incoming call during game play)? Thanks!


The current codes are implemented in SDL. A typical event loop looks like:


SDL_Event event;
int running = 1;
*
while(running) {
while(SDL_PollEvent(&event)) {
switch(event.type){
case SDL_KEYDOWN:
case SDL_KEYUP:
DisplayState(&event.key);
DisplayModifiers(&event.key);
DisplayKey(&event.key);
break;
case SDL_QUIT:
running = 0;
break;
}
}
}
