<p>The QFormBuilder class provides a mechanism for dynamically creating user interfaces at run-time, based on UI files created with <i>Qt Designer</i>. For example:</p>
<pre> MyForm.MyForm(QWidget *parent)
: QWidget(parent)
{
QFormBuilder builder;
QFile file(":/forms/myWidget.ui");
file.open(QFile.ReadOnly);
QWidget *myWidget = builder.load(&file, this);
file.close();
QVBoxLayout *layout = new QVBoxLayout;
layout->addWidget(myWidget);
setLayout(layout);
}</pre>
<p>By including the user interface in the example's resources (<tt>myForm.qrc</tt>), we ensure that it will be present when the example is run:</p>
<pre> <!DOCTYPE RCC><RCC version="1.0">
<qresource prefix="/forms">
<file>mywidget.ui</file>
</qresource>
</RCC></pre>
<p>QFormBuilder extends the <a href="qabstractformbuilder.html">QAbstractFormBuilder</a> base class with a number of functions that are used to support custom widget plugins:</p>
<ul>
<li><a href="qformbuilder.html#pluginPaths">pluginPaths</a>() returns the list of paths that the form builder searches when loading custom widget plugins.</li>
<li><a href="qformbuilder.html#addPluginPath">addPluginPath</a>() allows additional paths to be registered with the form builder.</li>
<li><a href="qformbuilder.html#setPluginPath">setPluginPath</a>() is used to replace the existing list of paths with a list obtained from some other source.</li>
<li><a href="qformbuilder.html#clearPluginPaths">clearPluginPaths</a>() removes all paths registered with the form builder.</li>
<li><a href="qformbuilder.html#customWidgets">customWidgets</a>() returns a list of interfaces to plugins that can be used to create new instances of registered custom widgets.</li>
</ul>
<p>The QFormBuilder 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> class, found in the <a href="qtuitools.html">QtUiTools</a> module.</p>
