How to show “spell” cba while user inserting text in T9 mode

Hello,

I am using CEikRichTextEditor to get user input. User input could be in T9 mode. So when user is inserting text in T9 mode and no text match found, it changes the cba button and shows “spell”. If user click spell, it bring one text dialog for user defined word and most probably it stores the word in T9 memory. For instance,

testing?


“Option Back” -> changes to “Spell Back”

I am wondering there must be some kind of flag or something to set in CEikRichTextEditor class to get this kind of options. Does anybody know how to do it? Thanks!
