NAME¶

SDL_HINT_KEYCODE_OPTIONS - A variable that controls keycode representation in keyboard events.

HEADER FILE¶

Defined in SDL3/SDL_hints.h

SYNOPSIS¶

#include "SDL3/SDL.h"

#define SDL_HINT_KEYCODE_OPTIONS SDL_KEYCODE_OPTIONS"

DESCRIPTION¶

This variable is a comma separated set of options for translating keycodes in events:

• "none": Keycode options are cleared, this overrides other options.

• "hide_numpad": The numpad keysyms will be translated into their
non-numpad versions based on the current NumLock state. For example,

SDLK_KP_4
would become SDLK_4
if

SDL_KMOD_NUM
is set in the event modifiers, and

SDLK_LEFT
if it is unset.

• "french_numbers": The number row on French keyboards is inverted, so
pressing the 1 key would yield the keycode SDLK_1 , or '1',
instead of SDLK_AMPERSAND , or '&'

• "latin_letters": For keyboards using non-Latin letters, such as Russian
or Thai, the letter keys generate keycodes as though it had an en_US
layout. e.g. pressing the key associated with

SDL_SCANCODE_A
on a Russian keyboard would yield 'a'
instead of a Cyrillic letter.

The default value for this hint is "french_numbers,latin_letters"

Some platforms like Emscripten only provide modified keycodes and the options are not used.

These options do not affect the return value of

SDL_GetKeyFromScancode () or

SDL_GetScancodeFromKey (), they just apply to the keycode included in key events.

This hint can be set anytime.

AVAILABILITY¶

This hint is available since SDL 3.1.3.
