Constant KEYCODE_OPTIONS

pub const KEYCODE_OPTIONS: &'static str;

Available on crate feature dep_sdl3 only.

A variable that controls keycode representation in keyboard events.

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.
