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 );
