But it doesn't work, like it works with DevExress controls.
After execution of code above, the red wave lines disappear, but if you type any char they became visible.
I See only one solution, make free all dictionary's from RvDxSpellChecker1 and then free RvDxSpellChecker1.
What do you think about it? It's seems to be a noobish solution but I can't find alternative
Yes, the current version of TRvDxSpellChecker always checks TcxTRichViewEdit controls, ignoring CheckAsYouTypeOptions.Active.
It will be fixed in the next update (planned in the beginning of the next week).
Due some reasons, it's quite tricky to stop checking while TcxTRichViewEdit is already being checked, so I'll add a new method
TRvDxSpellChecker.StopLiveSpelling
To start checking again, you will need to assign CheckAsYouTypeOptions.Active := True.
