40
Convert an SDL keysym to an ANSI/ASCII character.
41
This is used to type text and numeric values in input boxes.
42
@param keysym SDL symbol to convert
44
word Keysym_to_ANSI(SDL_keysym keysym);
47
Convert an SDL keysym to an internal keycode number.
48
This is needed because SDL tends to split the information across the unicode sym, the regular sym, and the raw keycode.
49
We also need to differenciate 1 (keypad) and 1 (regular keyboard), and some other things.
50
See the notice at the beginning of keyboard.h for the format of a keycode.
51
@param keysym SDL symbol to convert
53
word Keysym_to_keycode(SDL_keysym keysym);
56
Helper function to convert between SDL system and the old coding for PC keycodes.
57
This is only used to convert configuration files from the DOS version of
58
Grafx2, where keyboard codes are in in the IBM PC AT form.
59
@param scancode Scancode to convert
61
word Key_for_scancode(word scancode);
64
Returns key name in a string. Used to display them in the helpscreens and in the keymapper window.
65
@param Key keycode of the key to translate, including modifiers
67
const char * Key_name(word Key);
70
Gets the modifiers in our format from the SDL_Mod information.
71
Returns a combination of ::MOD_SHIFT, ::MOD_ALT, ::MOD_CONTROL
72
@param mod SDL modifiers state
74
word Key_modifiers(SDLMod mod);
