NAME
       itk - framework for building mega-widgets in Tcl/Tk

DESCRIPTION
       Mega-widgets are high-level widgets that are constructed using Tk
       widgets as component parts, usually without any C code.  A
       fileselectionbox, for example, may have a few listboxes, some entry
       widgets and some control buttons.  These individual widgets are put
       together in a way that makes them act like one big widget.  A
       fileselectionbox mega-widget can be created with a command like:
       fileselectionbox .fsb -background blue -foreground white Once it has
       been created, it can be reconfigured with a command like: .fsb
       configure -background green -foreground black and all of its internal
       components will change color.  Each mega-widget has a set of methods
       that can be used to manipulate it.  For example, the current selection
       can be queried from a fileselectionbox like this: set fileName [.fsb
       get] In effect, a mega-widget looks and acts exactly like a Tk widget,
       but is considerably easier to implement.

       [incr Tk] is a framework for building mega-widgets.  It uses [incr Tcl]
       to support the object paradigm, and adds base classes which provide
       default widget behaviors.

       All [incr Tk] widgets are derived from the Archetype base class.  This
       class manages internal component widgets, and provides methods like
       "configure" and "cget" to access configuration options.

       The Widget base class inherits everything from Archetype, and adds a Tk
       frame which acts as a container for the mega-widget.  It is used to
       build mega-widgets that sit inside of other frames and toplevels.
       Derived classes create other internal components and pack them into the
       "hull" frame created by the Widget base class.

       The Toplevel base class inherits everything from Archetype, but adds a
       Tk toplevel which acts as a container for the mega-widget.  It is used
       to build mega-widgets, such as dialog boxes, that have their own
       toplevel window.  Derived classes create other internal components and
       pack them into the "hull" toplevel created by the Toplevel base class.

[incr Widgets] LIBRARY
       [incr Widgets] is a mega-widget library built using [incr Tk].  It can
       be used right out of the box, and contains more than 30 different
       widget classes, including:

       -      fileselectiondialog

       -      tabnotebook

       -      panedwindow

       -      combobox

       -      optionmenu

       -      scrolledlistbox

       -      scrolledframe

       -      messagedialog

       -      and many others...

       The catalog demo in the "iwidgets/demos" directory shows all of the
       available widgets in action.  Each widget class has its own man page
       describing the features available.
