<p>
    Pmw is a framework for building high-level compound widgets, or
    <em>megawidgets</em>, constructed using other widgets as component parts. 
    It promotes consistent look and feel within and between graphical
    applications, is highly configurable to your needs and is easy to
    use.</p>

<p>    Pmw consists of:</p>
<ul><li><p>A few base classes, providing a framework for building
          megawidgets.</p>


<li><p>A library of flexible and extensible megawidgets built on
          the base classes, such as ButtonBox, ComboBox,
          MessageDialog, etc.</p>


<li><p>A lazy importer/dynamic loader which is automatically
          invoked when Pmw is first imported.  This gives unified
          access to all Pmw classes and functions though the <strong>Pmw.</strong>
          prefix.  It also speeds up module loading time by only
          importing Pmw sub-modules when needed.</p>


<li><p>Reference documentation, consisting of complete listings of
          megawidget options, methods and components.  Full
          descriptions are also available for all the base classes and
          several other megawidget classes.  Descriptions of the other
          megawidgets will be released soon.</p>


<li><p>A test framework and tests for both the Tkinter module and
          all the Pmw megawidgets.</p>


<li><p>A slick demonstration of the megawidgets.</p>


<li><p>An interface to the BLT busy, graph and vector commands.</p>

</ul>

<p>    The interface to Pmw megawidgets is similar to basic Tk widgets, so it
    is easy for developers to include both megawidgets and basic Tk
    widgets in their graphical applications.  In addition, all Pmw
    megawidgets may themselves be extended, using either inheritance or
    composition.</p>

<p>    The use of the Pmw framework and megawidgets replaces common
    widget combinations with higher level abstractions.  This
    simplifies code, making it more readable and maintainable and more
    easily modifiable.  The ability to extend Pmw megawidgets enables
    developers to create new megawidgets based on previous work.</p>
