| 563 we define the character-of-keysym property of its XEmacs keysym, and make | |
| 564 the default binding for the key be self-insert-command. | |
| 565 | |
| 566 The following magic is based on intimate knowledge of some of | |
| 567 X11/keysymdef.h. The keysym mappings defined by X11 are based on the | |
| 568 iso8859 standards, except for Cyrillic and Greek. | |
| 569 | |
| 570 In a non-Mule world, a user can still have a multi-lingual editor, by | |
| 571 doing (set-face-font "...-iso8859-2" (current-buffer)) for all their | |
| 572 Latin-2 buffers, etc. and the X11 keysyms corresponding to characters in | |
| 573 those character sets will still do the right thing (because of the | |
| 574 make_char (code + 0x80) non-Mule case below.) Of course, X11 keysyms in | |
| 575 other character sets will not do the right thing, because XEmacs won't | |
| 576 support the right thing. | |
| 577 | |
| 578 This code is also called when a command lookup is about to fail, and the | |
| 579 X11 platform code has worked out that it previously wasn't aware the | |
| 580 keysym of that command could be generated by the user's keyboard; in that | |
| 581 case, we bind its XEmacs keysym to self-insert-command if it has a | |
| 582 character correspondence we know about, and tell the general event code | |
| 583 that we've done so, so it can try the lookup again. | |
| 584 | |
| 585 Called from the GTK code because GTK 1 has no defined way of doing the | |
| 586 same thing, and this works for it on X11. It should be moved back into | |
| 587 event-Xt.c when and if the GTK port moves to GTK 2. */ | |
