<h2>Detailed Description</h2>
|
|
<p>The QAbstractFormBuilder class provides a default implementation 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>
