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.

      Should cpanminus be part of the standard Perl release?
