<span><a name="intro"></a><h2 class="title">Introduction</h2><p>On February 15, 2004 and for release 1.1 of HTML_Progress, the <i><b>HTML_Progress_Monitor</b></i>
class improved a lot. Features are :
<ul><li>both modes determinate/indeterminate supported for the progress meter</li>
<li>easy communication with your user-process</li>
<li>follow standard of QuickForm rendering</li>
<li>buttons size, dialog box and buttons title, all are customizable</li>
<li>different captions on user-process progress are allowed</li></ul>
User-end command actions to begin and cancel process. The progress bar won't start if the user
did not click on the 'Start' button. Once the process begun the start button is disabled.</p></span>
<span><a name="basic-concept"></a><h2 class="title">Basic concept</h2><p>Form and progress bar output are now contained in classes that extend
<i><b>HTML_QuickForm_Renderer</b></i>. Design pattern is much easier to manage
and change, and you can choose your favorite template engine.</p>
<p>There are 8 renderers available since release 3.1.1 of QuickForm. The following template engines
are directly suported: Smarty, HTML_Template_Sigma, HTML_Template_IT, HTML_Template_Flexy.
Among these 8 renderers, we will have a look on 3 examples in next chapters :
'default', 'default improved', 'template integration'.</p></span>
<span><a name="useit"></a><h2 class="title">Using Progress Monitor</h2><p><a name="useit.renderer-default"></a><h3 class="title">Default renderer</h3><p>Without any changes, you may obtains a decent dialog box with a default progress meter
such as :

<p>To make it possible, we have changed buttons size and internal QuickForm name
on <strong>lines 26 to 29</strong> (class constructor options), and written the
QF renderer on <strong>lines 71 to 84</strong>.
The progress bar look and feel is defined on <strong>lines 38 to 42</strong>.
Our user-process which run an indeterminate progress switching back to determinate mode
is defined by the 'myFunctionHandler' function (<strong>lines 4 to 24</strong>),
linked to the monitor on <strong>line 30</strong>.<br /></p><hr />
<a name="useit.renderer-template"></a><h3 class="title">Template engine integration</h3><p>Using Progress Monitor with a template engine supported by QF rendering system is very easy.
We will show you how to do with ITx (<a href="http://pear.php.net/package/HTML_Template_IT">http://pear.php.net/package/HTML_Template_IT</a>).
Example below will simulate a picture upload operation (3 steps: picture 1 at 10%,

<p><i><b>HTML_Progress_Monitor</b></i> class constructor options (<strong>lines 33 to 39</strong>)
allows to change buttons name and size, the dialog box title, and the internal QuickForm name.
User-process is now defined by a method-class on <strong>lines 6 to 31</strong>, and
linked to the monitor on <strong>line 40</strong>.<br />
The ITx template engine is initialized <strong>line 53</strong>, and loaded with template
<a href="http://pear.laurent-laville.org/HTML_Progress/apidoc/HTML/monitor_itdynamic_tpl.php">monitor_itdynamic.html</a>
(<strong>line 54</strong>).<br />
Finally we get the QF renderer on <strong>lines 61 to 64</strong>.<br /></p><hr /></p></span></div>
