Output parameter:

Misspelled, must be set to True if this word is misspelled.

 

Example (using Addict 3 spelling checker):

procedure TMyForm.MyRichViewEditSpellingCheck(Sender: TCustomRichView;

  const AWord: TRVUnicodeString; StyleNo: Integer;

  var Misspelled: Boolean);

begin

  Misspelled := not MyRVAddictSpell3.WordAcceptable(AWord);

end;

This event is called in thread context.

 

Using with TRVSpellChecker

You have two options:

▪register this TRichView component using RVSpelllChecker.RegisterEditor method (and this event will be processed automatically), or

▪process this event and use RVSpelllChecker.IsWordValid method.

 

FireMonkey note:

If the current platform provides a spelling checking service, TRichViewEdit can use it (see CheckSpelling property). In this case, checking does not require this event (however, if this event is assigned, it has a higher priority than a platform service).
