for classes that create user interfaces at run-time.</p>
<p>QAbstractFormBuilder provides a standard interface and a default
implementation for constructing forms from user interface files. It
is not intended to be instantiated directly. Use the <a href="qformbuilder.html">QFormBuilder</a> class to create user
interfaces from UI files at run-time. For example:</p>
<pre class="cpp">
MyForm<span class="operator">.</span>MyForm(<span class="type"><a href="qwidget.html">QWidget</a></span> <span class="operator">*</span>parent)
: <span class="type"><a href="qwidget.html">QWidget</a></span>(parent)
{
<span class="type"><a href="qformbuilder.html">QFormBuilder</a></span> builder;
<span class="type"><a href="qfile.html">QFile</a></span> file(<span class="string">":/forms/myWidget.ui"</span>);
file<span class="operator">.</span>open(<span class="type"><a href="qfile.html">QFile</a></span><span class="operator">.</span>ReadOnly);
<span class="type"><a href="qwidget.html">QWidget</a></span> <span class="operator">*</span>myWidget <span class="operator">=</span> builder<span class="operator">.</span>load(<span class="operator">&</span>file<span class="operator">,</span> <span class="keyword">this</span>);
file<span class="operator">.</span>close();
<span class="type"><a href="qvboxlayout.html">QVBoxLayout</a></span> <span class="operator">*</span>layout <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qvboxlayout.html">QVBoxLayout</a></span>;
layout<span class="operator">-</span><span class="operator">></span>addWidget(myWidget);
setLayout(layout);
}
</pre>
<p>To override certain aspects of the form builder's behavior,
subclass QAbstractFormBuilder and reimplement the relevant virtual
functions:</p>
<ul>
<li><a href="qabstractformbuilder.html#load">load</a>() handles
reading of UI format files from arbitrary QIODevices, and
construction of widgets from the XML data that they contain.</li>
<li><a href="qabstractformbuilder.html#save">save</a>() handles
saving of widget details in UI format to arbitrary QIODevices.</li>
<li><a href="qabstractformbuilder.html#workingDirectory">workingDirectory</a>()
and <a href="qabstractformbuilder.html#setWorkingDirectory">setWorkingDirectory</a>()
control the directory in which forms are held. The form builder
looks for other resources on paths relative to this directory.</li>
</ul>
<p>The <a href="qformbuilder.html">QFormBuilder</a> class is
typically used by custom components and applications that embed
<i>Qt Designer</i>. Standalone applications that need to
dynamically generate user interfaces at run-time use the <a href="quiloader.html">QUiLoader</a>, found in the <a href="qtuitools.html">QtUiTools</a> module.</p>
