Question

When I want to output colorized string (red color) in terminal I use:

puts "\033\[00;31m Test String \033\[0m"

But when I print this string in text widget I get:

[00;31m Test String [0m

How to print the same colorized string in text widget?

Answer 1

As far as I understand the question it is about applying formatting to content of text widget which has to do with Tk and not with escape sequences. This can be achieved through tags. Here is the code that would create a text widget, put two lines into it and highlight the second line with red.

set t [text .t -height 10 -width 40]
pack $t
$t insert end "text1\n"
$t insert end "text2\n"
$t tag add my_red 2.0 2.end
$t tag configure my_red -foreground red

I hope this helps if the question is just about formatting.
