    Some questions after reading the code:

    Your rotext seems to disable interactive editing (i.e. anything done through the bindings), and allow non-interactive (programmatic) editing. Is that right ?

    Is this based per-chance on some code on the Tcler's Wiki (http://wiki.tcl.tk) ?
    If yes, that are the page numbers ?

    Note that an alternative way of doing a rotext is wrap around text and disable the 'insert' and 'delete' method, without touching the bindings . This will disable all editing, interactive and programmatic. The latter can then be restored by providing differently named methods for programmatic access.

    Yes, you are right.

    I write this code myself, but idea is so simple, so may be wiki contains simular code.

    I saw such alternative code on the Tcl wiki, but my idea was leave text api as is, just disable interactive editing. Example, in my application I have one text widget for code editing, one other text widget for viewing this code after some preprocessor. Also, I found this widget useful in some other situations.

    P.S: may be it will be good to add my code to widget::scrolledtext, but this at your discretion.
