NSTextView has this:

- (NSRange)selectionRangeForProposedRange:(NSRange)proposedSelRange granularity:(NSSelectionGranularity)granularity

So if the proposedSelRange is a zero-length range at the character index determined before, and granularity is NSSelectByWord, it should return the range of the word.

hth,

Graham,

Thanks for your reply! But how can I "find the range of the word" given
the glyph index?  I just can not find an API doing so.

So I don't think this is the underlying implementation.  Any comments
from others?

I imagine it uses some API such as NSLayoutManager's:

- (NSUInteger)glyphIndexForPoint:(NSPoint)point
inTextContainer:(NSTextContainer *)container
fractionOfDistanceThroughGlyph:(CGFloat *)partialFraction


One you have the glyph index you can find the range of the word it belongs
to.

One you have the string of the word it belongs to, you can look it up in
dictionary.app using the Application Services API.


hth, though I am guessing to some extent.
