Spell checker for Qt application Editor

Hi All we would like to have spelling checker mechanism embedded in our one of the small editor in our application, we were wondering is there any class/any thing available in Qt?

I am unable to reach on this link it seems not working. Is this any third party stuff or is this gitorius link?

As I see several years ago there was a similar question on Trolltech discussion "here":http://lists.trolltech.com/qt-interest/2003-03/thread01029-0.html

Thank you for the pointer, it looks like there is nothing inbuilt in Qt for this. Has any one does this before using some third party library or what ever, I would really appreciate if I get some example or good tutorial how to do it

"This":http://bugreports.qt.nokia.com/browse/QTBUG-14462 should help you get some references and background.

We've added "hunspell":http://hunspell.sourceforge.net/ to QTextEdit in our application. For that we created a small Qt-ish C++ wrapper around a Hunspell object. There are methods spell() for correct spelling yes/no, suggest() for suggestion for replacement words, put_word() for temporarily putting a word into the dictionary to ignore it and addToUserWordlist() for creating a user dictionary. It's quite straightforward.

Maybe I'll make a wiki page, once I have extracted the code for a small standalone app.

volker that would so great if you could find some time to put up one small stand alone example which demonstrate how it can be done. Though I have just downloaded it and will be playing around. Any thing from existing user is ++ as they know the small glitches which saves others time

Nice to see that you are using some Hungarian developed resources :)

VCsala, yes, I know the fact. And it indeed fits well in our German needs, as the structure of both languages is quite similar. And it's LGPL/MIT licensed and thus usable in our commercial project.

Thanx Qtk, I am able to checkout now. Hope this serve my Need.

The sources on gitorious seem to be a Qt libs project, that means it's the regular Qt libs enhanced with some built-in spell checkers. Unfortunately I doubt it is usable for mort than some tests at the moment.

I've added the spell checker example on the wiki page "Spell Checking with Hunspell ":http://developer.qt.nokia.com/wiki/Spell_Checking_with_Hunspell. It's not the most beautiful code in the world, but it works for me :-) Hopefully it's useful for someone else.

@Volker
is it allowed in an commercial app (like you also use) to embed the hunspell libs into the application as a static lib?

afaik lgpl says, it has to be replace able?

goetz · wrote on 16 Nov 2011, 13:23

It just works the same with using dynamic/shared libs (DLLs).

Jupiter · wrote on 16 Nov 2011, 20:57

well actually when i change it to @LIBS += -L<myLibPath> -lhunspell@ it doesn't link also tried -llibhunspell -lhunspell-1.3 almost every combination. but it does not link. any ideas about that?

What files do you have in your lib path?
