erasing a character in a text box

[erixire]

Hi,

Is it possible to erase (backspace) a character in a text box, because I tried the "\b" with no effect like this:

$text insert end "before"
$text insert end "\b\b\b\b\b\b after"

Thanks for any help.

The \b char has no binding yet.
You need to add one:

pack [text .t]
bind .t <Control-KeyPress-b> { 
  # delete the char
  .t delete {insert - 1 char}
  # set the insert point
  .t mark set insert {insert + 1 char}
}
.t insert end &quot;a text to insert xx\n&quot;

For this to work fine be sure the text ends with a \n.

Good luck
