<p>Pmw.Blt -
    interface to some BLT widgets and commands</p>
<p></p>


</dd>
<dt> <h3>Description</h3></dt><dd>
<p>
    This module contains function interfaces to the BLT <code>busy</code> command
    as well as the classes <strong>Pmw.Blt.Vector</strong>, <strong>Pmw.Blt.Graph</strong>,
    <strong>Pmw.Blt.Stripchart</strong> and <strong>Pmw.Blt.Tabset</strong>, which are interfaces to
    the vector, graph, stripchart and tabset commands of version 2.4
    of the <strong>BLT</strong> extension to Tk.  The interfaces are complete except
    for <strong>Pmw.Blt.Vector</strong> where several creation options, methods and
    operations have not been implemented.</p>

<p>    The blt graph and barchart widgets are essentially the same and so
    only the graph widget has been ported.  The <code>element_create()</code>
    method is not implememted for <strong>Pmw.Blt.Graph</strong>, so instead:</p>
<ul><li><p>to create a <em>line</em> element, use the <code>line_create()</code> method and</p>

</li>
<li><p>to create a <em>bar</em> element, use the <code>bar_create()</code> method.</p>

</li></ul>

<p>    To operate on elements, use the <code>element_*()</code> methods, such as
    <code>element_bind()</code>, <code>element_activate()</code>, etc.</p>

<p>    <strong>Note:</strong> Full documentation of Pmw.Blt.Graph is available in
    <a href="http://www.ifi.uio.no/~hpl/Pmw.Blt/doc/">A User's Guide to Pmw.Blt</a>
    written by Bjørn Ove Thue and Hans Petter Langtangen.
