From: Daniel Pitts on 15 Jul 2010 14:36 I'd like to emulate the Firefox/thunderbird real-time spell-checking feature in a (signed) Java applet. Right now, the user is entering data in a JTextArea, but I'm willing to replace that, as long as the replacement has word-wrap. If there are good libraries available that don't have UI integration, that's fine too, I can probably handle that part myself. Grammar suggestion is a nice-to-have. I only need, and will probably only ever need English correction. To be specific, The goal is to provide red-underlined text for misspelled words, and allow easy correction from a pop up/context menu. -- Daniel Pitts' Tech Blog: <http://virtualinfinity.net/wordpress/>

I did forget to mention that free is very important, and open-source is a big nice-to-have. -- Daniel Pitts' Tech Blog: <http://virtualinfinity.net/wordpress/>

Hunspell is what Mozilla code is currently using, and Google suggests that there exists Java bindings: <http://dren.dk/hunspell.html>. That only gets whether or not a word is misspelled as well as suggestions for the word. The UI should be fairly simple. You can use the Highlighter class (DefaultHighlighter is probably sufficient to use), as well as text modification listener to figure out when words are being added, to tell the text to only highlight a portion of the text. I'm not sure if highlighters shift their ranges in response to text modification, though... -- Beware of bugs in the above code; I have only proved it correct, not tried it. -- Donald E. Knuth
