NAME
       Tk::TraceText - Text contents defined by a traced variable.

SYNOPSIS
        $tt = $parent->TraceText(-option => value, ... );

DESCRIPTION
       Create a new TraceText widget that is derived from the standard Text
       widget. Because it inherits all the base options and methods it behaves
       just like a Text widget.  Additionally, TraceText adds a -textvariable
       option, which is a reference to a Perl scalar that defines the contents
       of the widget.

       Based on the Tcl/Tk TracedText "overridden widget" by Kevin Kenny.

       -textvariable
           A scalar reference.  The value of the variable defines the contents
           of the TraceText widget.  Using the keyboard to insert or delete
           text changes the value of the variable, and changing the variable
           alters the contents of the TraceText widget.

METHODS
       Standard Text widget methods.

ADVERTISED SUBWIDGETS
       None.

EXAMPLE
        my $tt = $mw->TraceText( -textvariable => \$scalar );
