Event Handling

Include File(s): SDL_events.h


Event handling allows your application to receive input from the user. Event handling is initialized (along with video) with a call to:


(see Initialization & Shutdown and SDL_Init() for details)

Internally, SDL stores all the events waiting to be handled in an event queue. Using functions like SDL_PollEvent(), SDL_PeepEvents() and SDL_WaitEvent() you can observe and handle waiting input events.

The event queue itself is composed of a series of SDL_Event structures, one for each waiting event. SDL_Event structures are read from the queue with the SDL_PollEvent() function and it is then up to the application to process the information stored with them.
