This seems to assume that there are \n characters in the strings. I am using -wrap => 1, to get automatic line wraps, and I don't think that it inserts \n in the string.

Hm. I could be wrong, but I'd bet my bottom dollar that wrap is implemented by inserting newlines into the text.

This part of the tcl code:if {[set n [llength [split [.table get $r,$c] \n]]]>1 && $maxh<$n} { breaks down to:

  1. Get the text from cell $r, $c: [.table get $r,$c]
  2. Split that text on newlines: [split $text \n]
  3. Calculate the list length of the result from split: [llength <list> ]
  4. Set n to that value: [set n $length ]
  5. If the number of lines is greater than one; and greater than the current value of maxh(eight), then set maxh to n;

    (Note: that first test is redundant.)

You would be wasting your time doing font calculations yourself, cos the tablematrix must already be doing them in order to perform the wrapping.
