- Log:
First stage commit of Typo 4.1, modified for the ROOL site.
Includes all local modifications but a final pass needs to be
made to delete any files left over from earlier Typo versions
that shouldn't be here anymore. See the 'tags' section of the
repository for a clean Typo 4.1 tree.Note that symlinks to shared files in the RISC OS Open theme
directory have been deliberately included this time around; I
decided that on balance it was better to leave them in as
placeholders, since unlike symlinks in app/views/shared, the
Typo theme structure is not a standard Rails concept.

12 | // Autocompleter.Base handles all the autocompletion functionality |
13 | // that's independent of the data source for autocompletion. This |
14 | // includes drawing the autocompletion menu, observing keyboard |
15 | // and mouse events, and similar. |
16 | // |
17 | // Specific autocompleters need to provide, at the very least, |
18 | // a getUpdatedChoices function that will be invoked every time |
19 | // the text inside the monitored textbox changes. This method |
20 | // should get the text for which to provide autocompletion by |
21 | // invoking this.getToken(), NOT by directly accessing |
22 | // this.element.value. This is to allow incremental tokenized |
23 | // autocompletion. Specific auto-completion logic (AJAX, etc) |
24 | // belongs in getUpdatedChoices. |
25 | // |
26 | // Tokenized incremental autocompletion is enabled automatically |
27 | // when an autocompleter is instantiated with the 'tokens' option |
28 | // in the options parameter, e.g.: |
29 | // new Ajax.Autocompleter('id','upd', '/url/', { tokens: ',' }); |
30 | // will incrementally autocomplete with a comma as the token. |
31 | // Additionally, ',' in the above example can be replaced with |
32 | // a token array, e.g. { tokens: [',', '\n'] } which |
33 | // enables autocompletion on multiple tokens. This is most |
34 | // useful when one of the tokens is \n (a newline), as it |
35 | // allows smart autocompletion after linebreaks. |
