David,
I think you are confused because you chose an unfornunate example.
['Dog','Cow','Coyote']
The length of the lines are 5, 5, and 8 which add to 18. I assume it is the
characters in the line plus a line feed and <cr>. So that Line 0 starts at
offset 0, line 1 starts at offset 5 and line 3 starts at offset 10.
Since the Text_Offset_to_XY keyword in Widget_Info does not seem to work
right, you will have to compute the offsets to each line manually by
accummulating the string lengths plus 2 for all previous lines.
Wouldn't a list widget work better for what you are doing?
