Am I doing something wrong or is this approach a dead end?
My guess is that the TableMatrix widget keeps two copies of the text. One that reflects the applications view of that text; and one that gets manipulated for the display purposes. And what you are querying is the former rather than the latter.
Maybe if you could work out the appropriate incantations for using the windowCget() method to obtain the text from the cells directly rather than via the TableMatrix, it might return the wrapped text.
But, I'm guessing. I pretty much gave up trying to do anything clever with Tk because the (perl/tk) docs are so bad; and half of what you see in the tcl samples doesn't translate. Sorry.
