With VCL 15.2.3, you can use the ExpressSpellChecker (the TdxSpellChecker component) to check spelling in the Rich Edit control.
To start spell checking, add the TdxSpellChecker component (if none already exists) to your form and do one of the following:
- Use the spell checker's API (call the Check method or enable the Check As You Type or AutoCorrect mode);
- Execute the new TdxRichEditControlCheckSpelling action available in the Rich Edit control.
In Check As You Type or AutoCorrect mode, end-users can check spelling and correct spelling errors by invoking the Rich Edit control's context menu for a misspelled word (which is highlighted with a line) and clicking the Spelling or AutoCorrect menu item.
