<p>
Pmw is a toolkit 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 foundation for building
megawidgets.</p>
<li><p>A library of flexible and extensible megawidgets built on
the base classes, such as buttonboxes, notebooks,
comboboxes, selection widgets, paned widgets, scrolled
widgets and dialog windows.</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 through 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 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, Pmw
megawidgets may themselves be extended, using either inheritance or
composition.</p>
<p> The use of the Pmw megawidgets replaces common widget combinations
with higher level abstractions. This simplifies code, making it
more readable and maintainable. The ability to extend Pmw
megawidgets enables developers to create new megawidgets based on
previous work.</p>
