SDL_KeyboardEvent(3)						 SDL API Reference					      SDL_KeyboardEvent(3)

NAME
SDL_KeyboardEvent - Keyboard event structure STRUCTURE DEFINITION
typedef struct{ Uint8 type; Uint8 state; SDL_keysym keysym; } SDL_KeyboardEvent; STRUCTURE DATA
type SDL_KEYDOWN or SDL_KEYUP state SDL_PRESSED or SDL_RELEASED keysym Contains key press information DESCRIPTION
SDL_KeyboardEvent is a member of the SDL_Event union and is used when an event of type SDL_KEYDOWN or SDL_KEYUP is reported. The type and state actually report the same information, they just use different values to do it! A keyboard event occurs when a key is released (type=SDK_KEYUP or state=SDL_RELEASED) and when a key is pressed (type=SDL_KEYDOWN or state=SDL_PRESSED). The information on what key was pressed or released is in the keysym structure. Note: Repeating SDL_KEYDOWN events will occur if key repeat is enabled (see SDL_EnableKeyRepeat). SEE ALSO

NAME
SDL_keysym - Keysym structure STRUCTURE DEFINITION
typedef struct{ Uint8 scancode; SDLKey sym; SDLMod mod; Uint16 unicode; } SDL_keysym; STRUCTURE DATA
scancode Hardware specific scancode sym SDL virtual keysym mod Current key modifiers unicode Translated character DESCRIPTION
The SDL_keysym structure is used by reporting key presses and releases since it is a part of the SDL_KeyboardEvent. The scancode field should generally be left alone, it is the hardware dependent scancode returned by the keyboard. The sym field is extremely useful. It is the SDL-defined value of the key (see SDL Key Syms. This field is very useful when you are checking for certain key presses, like so: . . while(SDL_PollEvent(&event)){ switch(event.type){ case SDL_KEYDOWN: if(event.key.keysym.sym==SDLK_LEFT) move_left(); break; . . . } } . . mod stores the current state of the keyboard modifiers as explained in SDL_GetModState. The unicode is only used when UNICODE translation is enabled with SDL_EnableUNICODE. If unicode is non-zero then this a the UNICODE character corresponding to the keypress. If the high 9 bits of the character are 0, then this maps to the equivalent ASCII character: char ch; if ( (keysym.unicode & 0xFF80) == 0 ) { ch = keysym.unicode & 0x7F; } else { printf("An International Character. "); } UNICODE translation does have a slight overhead so don't enable it unless its needed. SEE ALSO
