NAME

       widget - Demonstration of Perl/Tk widgets

SYNOPSYS

	 widget [ directory ]

DESCRIPTION

       This script demonstrates the various widgets provided by Tk, along with many of the features of the Tk toolkit.	This file only contains
       code to generate the main window for the application, which invokes individual demonstrations.  The code for the actual demonstrations is
       contained in separate ".pl" files in the "widget_lib" directory, which are autoloaded by this script as needed.

       widget looks in the directory specified on the command line to load user contributed demonstrations.  If no directory name is specified
       when widget is invoked and the environment variable WIDTRIB is defined then demonstrations are loaded from the WIDTRIB directory. If
       WIDTRIB is undefined then widget defaults to the released user contributed directory, "widtrib".

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 );
