Is TRVHunSpell thread-safe and can be used for multiple editors?

Hi Sergey,

Can one TRVHunSpell object (alone with a TRVAHunSpellInterface) be used by multiple editors for live spell check? As we know, the OnSpellingCheck event is called in a background thread.

According to the RichViewAtions document:

Create TRVAHunSpellInterface component, assign it to SpellInterface property of TRVAControlPanel component.

Create TRVHunSpell component, assign it to HunSpell property of this TRVAHunSpellInterface component.

Currently I have only a single TRVAControlPanel but have multiple editors. By looking at the TRichViewEdit source code, I found that each editor has its own spell check thread. Does it mean with the approach above, there will be multiple threads accessing the same TRVAHunSpellInterface/TRVHunSpell pair?

Yes, there will be one thread for each editor.
So I recommend to protect OnSpellingCheck code by a TCriticalSection.

Great, it's a piece of cake!
