<p>
If you already use HTML_QuickForm you certainly know that the QF
default renderer has limited possibilities. But of course
HTML_QuickForm provides other renderers that can be used with template
engines such as Smarty, Sigma, ... And of course
HTML_Progress2_Generator has two interfaces (SmartyDynamic, ITDynamic)
to use these QF renderers.
</p>
<p>
Don't forget that you can also use the PEAR <a class="external" href=
"http://pear.php.net/package/HTML_Page2" title=
"http://pear.php.net/package/HTML_Page2">HTML_Page2</a> package and
since the version 2.1.0 the new Tableless QF renderer (PEAR package
<a class="external" href=
"http://pear.php.net/package/HTML_QuickForm_Renderer_Tableless" title=
"http://pear.php.net/package/HTML_QuickForm_Renderer_Tableless">HTML_QuickForm_Renderer_Tableless</a>).
</p>
<p>
In this example, we will see how it's so easy to include an instance of
HTML_Progress2_Generator in a user page (with header and menus, body,
footer); see screenshot below. We will use <a class="external" href=
"http://pear.php.net/package/HTML_Template_Sigma" title=
"http://pear.php.net/package/HTML_Template_Sigma">Sigma</a>, but there
is no much more difficulty to implement Smarty, or any other template
engine.
</p>
<p>
Color, font, size and position are defined by default in stylesheet
<span class="bold"><strong>itdynamic.css</strong></span> you can find
into PEAR HTML_Progress2 data directory.
</p>
<div class="screenshot">
<img src="img/generator1.png" alt="" />
</div>
<p>
Essantial difference with previous examples is to include the right
driver (ITDynamic).

<p>
Adding this line allow to define an ActionDisplay class (default
name to display driver) that will create a new instance of Sigma
with current directory '.' as template root dir, and 'cache/' as
template cache dir. The template itself is named
'itdynamic.html'.

You can, of course reuse such values with your own
documents, or use new ones. In such condition, you will
have to create a copy of ActionDisplay class
