/* For every key on the keyboard that has a known character correspondence, we define the character-of-keysym property of its XEmacs keysym, and make the default binding for the key be self-insert-command. The following magic is based on intimate knowledge of some of X11/keysymdef.h. The keysym mappings defined by X11 are based on the iso8859 standards, except for Cyrillic and Greek. In a non-Mule world, a user can still have a multi-lingual editor, by doing (set-face-font "...-iso8859-2" (current-buffer)) for all their Latin-2 buffers, etc. and the X11 keysyms corresponding to characters in those character sets will still do the right thing (because of the make_char (code + 0x80) non-Mule case below.) Of course, X11 keysyms in other character sets will not do the right thing, because XEmacs won't support the right thing. This code is also called when a command lookup is about to fail, and the X11 platform code has worked out that it previously wasn't aware the keysym of that command could be generated by the user's keyboard; in that case, we bind its XEmacs keysym to self-insert-command if it has a character correspondence we know about, and tell the general event code that we've done so, so it can try the lookup again. Called from the GTK code because GTK 1 has no defined way of doing the same thing, and this works for it on X11. It should be moved back into event-Xt.c when and if the GTK port moves to GTK 2. */ #ifndef THIS_IS_GTK static Lisp_Object x_keysym_to_character (KeySym keysym) #else Lisp_Object gtk_keysym_to_character (guint keysym) #endif { Lisp_Object charset = Qzero; int code = 0; /* Markus Kuhn's spec says keysyms in the range #x01000100 to #x0110FFFF and only those should correspond directly to Unicode code points, in the range #x100-#x10FFFF; actual implementations can have the Latin 1 code points do the same thing with keysyms #x01000000-#x01000100. */ if (keysym >= 0x01000000 && keysym <= 0x0110FFFF) return Funicode_to_char (make_fixnum (keysym & 0xffffff), Qnil); if ((keysym & 0xff) < 0xa0) return Qnil; switch (keysym >> 8) { #define USE_CHARSET(var,cs) \ ((var) = charset_by_leading_byte (LEADING_BYTE_##cs)) case 0: /* ASCII + Latin1 */ USE_CHARSET (charset, LATIN_ISO8859_1); code = keysym & 0x7f; break; case 1: /* Latin2 */ USE_CHARSET (charset, LATIN_ISO8859_2); code = keysym & 0x7f; break; case 2: /* Latin3 */ USE_CHARSET (charset, LATIN_ISO8859_3); code = keysym & 0x7f; break; case 3: /* Latin4 */ USE_CHARSET (charset, LATIN_ISO8859_4); code = keysym & 0x7f; break; case 4: /* Katakana */ USE_CHARSET (charset, KATAKANA_JISX0201); if ((keysym & 0xff) > 0xa0) code = keysym & 0x7f; break; case 5: /* Arabic */ USE_CHARSET (charset, ARABIC_ISO8859_6); code = keysym & 0x7f; break; case 6: /* Cyrillic */ { USE_UNICODE_MAP (keysym, CYRILLIC); break; } case 7: /* Greek */ { static UExtbyte const greek[] = /* 0x20 - 0x7f */ {0x00, 0x36, 0x38, 0x39, 0x3a, 0x5a, 0x00, 0x3c, 0x3e, 0x5b, 0x00, 0x3f, 0x00, 0x00, 0x35, 0x2f, 0x00, 0x5c, 0x5d, 0x5e, 0x5f, 0x7a, 0x40, 0x7c, 0x7d, 0x7b, 0x60, 0x7e, 0x00, 0x00, 0x00, 0x00, 0x00, 0x41, 0x42, 0x43, 0x44, 0x45, 0x46, 0x47, 0x48, 0x49, 0x4a, 0x4b, 0x4c, 0x4d, 0x4e, 0x4f, 0x50, 0x51, 0x53, 0x00, 0x54, 0x55, 0x56, 0x57, 0x58, 0x59, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x61, 0x62, 0x63, 0x64, 0x65, 0x66, 0x67, 0x68, 0x69, 0x6a, 0x6b, 0x6c, 0x6d, 0x6e, 0x6f, 0x70, 0x71, 0x73, 0x72, 0x74, 0x75, 0x76, 0x77, 0x78, 0x79, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00}; USE_CHARSET (charset, GREEK_ISO8859_7); code = greek[(keysym & 0x7f) - 0x20]; break; } case 8: USE_UNICODE_MAP (keysym, TECHNICAL); break; case 9: USE_UNICODE_MAP (keysym, SPECIAL); break; case 10: USE_UNICODE_MAP (keysym, PUBLISHING); break; case 11: USE_UNICODE_MAP (keysym, APL); break; case 12: /* Hebrew */ USE_CHARSET (charset, HEBREW_ISO8859_8); code = keysym & 0x7f; break; case 13: /* Thai */ /* #### This needs to deal with character composition.
