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 );
