<p>
An about dialog is a dialog window which displays information
about the application, such as name, version, copyright and
contact details.</p>
<p> The text of the message is constructed from the application name
(given by the <strong>applicationname</strong> option) followed by the values
supplied in the most recent calls to <code>Pmw.aboutversion()</code>,
<code>Pmw.aboutcopyright()</code> and <code>Pmw.aboutcontact()</code> functions.</p>
<p> The icon of the message defaults to <strong>'info'</strong>, but may be changed
using the <strong>icon_bitmap</strong> component option.</p>

</dd></dl>
<a name=option.command></a>
<dl><dt> <strong>command
</strong></dt><dd>
Specifies a function to call whenever a button in the button box
is invoked or the window is deleted by the window manager. The
function is called with a single argument, which is the name of
the button which was invoked, or <strong>None</strong> if the window was deleted
by the window manager.</p>
<p> If the value of <strong>command</strong> is not callable, the default behaviour
is to deactivate the window if it is active, or withdraw the
window if it is not active. If it is deactivated, <code>deactivate()</code>
is called with the button name or <strong>None</strong> as described above. The default is <strong>None</strong>.</p>
</dd></dl>
<a name=option.deactivatecommand></a>
<dl><dt> <strong>deactivatecommand
</strong></dt><dd>
If this is callable, it will be called whenever the megawidget is
deactivated by a call to <code>deactivate()</code>. The default is <strong>None</strong>.</p>
</dd></dl>
<a name=option.defaultbutton></a>
<dl><dt> <strong>defaultbutton
</strong></dt><dd>
Specifies the default button in the button box. If the <strong><Return></strong>
key is hit when the dialog has focus, the default button will be
invoked. If <strong>defaultbutton</strong> is <strong>None</strong>, there will be no default

<a name=option.separatorwidth></a>
<dl><dt> <strong>separatorwidth
</strong></dt><dd>

width will be created between the button box and the child site,

</dd></dl>
<a name=component.icon></a>
<dl><dt> <strong>icon
</strong></dt><dd>
