[WINTCL] how to display line number in a text widget?

[Bruno V. <br...@sd...>]

Hello,
I would like to know how can I display each line number from a text =
entry box? Should I create an additional text entry box, close the the =
main one, just to display the number of each line (and link the scroll =
bar to the main scroll bar)?
Thanks for your help.
