Event Handling

'''Include File(s):''' [http://hg.libsdl.org/SDL/file/default/include/SDL_events.h SDL_events.h]

Introduction

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

SDL_Init(SDL_INIT_VIDEO);

(''see'' [[CategoryInit|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.
