addTabSelectedHandler() or addTabDeselectedHandler() if those tabs are part of the same tabset.

Thanks very much for your reply. They are not part of same tab. Somehow I want to check whether the grid is loosing focus. Please let me know How can I do it.


Thanks

Well there are things like FocusChangedHandler() and BlurHandler() but it seems like what are looking for is really when the user does something that makes the grid no longer visible correct?

Thanks for your reply svjard. Yes. When the user chages something and get his mouse out of the grid the I want to display some message..I tried FocusChangedHandler()..but it doesn't seem working..I don't see BlurHandler() in the grid. Pelase let me know how can I fix it.

Thanks
