TRVACustomSpellInterface

A base class for RichViewActions spelling check interface components.

Unit RVADownloadInterface;

TRVACustomDownloadInterface = class (TComponent);

Description

This component is not used directly. Instead, use one of the following components inherited from it:

•TRVAAddictSpellInterface (to use Addict)

•TRVAASpellInterface (to use ASpell)

•TRVADXSpellInterface (to use ExpressSpellChecker)

•TRVAHunSpellInterface (to use HunSpell)

•TRVAPolarSpellInterface (to use Polar SpellChecker)

To use a spelling check interface component, assign it to SpellInterface property of TRVAControlPanel component.

Then you can:

•use TrvActionSpellingCheck action

•use TrvActionThesaurus action (if the chosen interface component supports a thesaurus)

•call its AutoCorrectInKeyDown in the editor's OnKeyDown event and AutoCorrectInKeyPress in the editor's OnKeyPress (in OnUTF8KeyPress for Lazarus) event to perform auto-correction on typing (if the chosen interface component supports an auto-correction)

•assign the inverted result of its IsWordValid method to the Misspelled parameter of the editor's OnSpellingCheck event to perform a live spelling check.
