WPTools comes with an integrated spell check interface which can be used by the third party products Addict Spell and EDSSpell. (Please see latest partner links)
Our own product WPSpell also uses this procedures and events.

To activate the spell check interface all you have to do:
| • | with Addict Spell: add unit WPTAddict to the project and use the WPTools spell check actions. |
| • | with EDSSpell: add unit eds_wptools to the project |
| 1. | Drop the component TWPSpellController  (activate symbol WPSEPLL in file WPINC.INC to compile it into the WPTools package) |
| 2. | Set the property WPSpellController1.Active to TRUE |
| 3. | Add the unit wpspell_link to the uses clause |
| 4. | Use the command WPRichText1.StartSpellCheck() to start/stop spellcheck |
| • | with WPSpell: (demo version) |
