<!-- $$$uic.html-description -->
<div class="descr"> <a name="details"></a>
<p>This page documents the <i>User Interface Compiler</i> for the Qt Widgets module. The <code>uic</code> reads an XML format user interface definition (<code>.ui</code>) file as generated by Qt Designer and creates a corresponding C++ header file.</p>
<p>Usage:</p>
<pre class="cpp">
uic <span class="operator">[</span>options<span class="operator">]</span> <span class="operator"><</span>uifile<span class="operator">></span>
</pre>
<a name="options"></a>
<h2 id="options">Options</h2>
<p>The following table lists the command-line options recognized by <code>uic</code>.</p>
<div class="table"><table class="generic">
<thead><tr class="qt-style"><th >Option</th><th >Description</th></tr></thead>
<tr valign="top" class="odd"><td ><code>-o <file></code></td><td >Write output to <code><file></code> instead of to standard output.</td></tr>
<tr valign="top" class="even"><td ><code>-tr <func></code></td><td >Use <code><func></code> for translating strings instead of <code>tr()</code>.</td></tr>
<tr valign="top" class="odd"><td ><code>-p</code></td><td >Don't generate guards against multiple inclusion (<code>#ifndef</code> FOO_H ...).</td></tr>
<tr valign="top" class="even"><td ><code>-h</code></td><td >Display the usage and the list of options.</td></tr>
<tr valign="top" class="odd"><td ><code>-v</code></td><td >Display <code>uic</code>'s version number.</td></tr>
<tr valign="top" class="even"><td ><code>-d</code></td><td >Display the dependencies for the UI.</td></tr>
<tr valign="top" class="odd"><td ><code>-n</code></td><td >Don't generate any #include directives.</td></tr>
<tr valign="top" class="even"><td ><code>--postfix <postfix></code></td><td >Append <code><postfix></code> to all generated classnames.</td></tr>
<tr valign="top" class="odd"><td ><code>--include <file></code></td><td >Add #include <code><file></code> to the output.</td></tr>
</table></div>
<a name="examples"></a>
<h2 id="examples">Examples</h2>
<p>If you use <code>qmake</code>, <code>uic</code> will be invoked automatically for header files.</p>
<p>Here are useful makefile rules if you only use GNU make:</p>
<pre class="cpp">
ui_<span class="operator">%</span><span class="operator">.</span>h: <span class="operator">%</span><span class="operator">.</span>ui
uic $<span class="operator"><</span> <span class="operator">-</span>o $@
</pre>
<p>If you want to write portably, you can use individual rules of the following form:</p>
<pre class="cpp">
ui_foo<span class="operator">.</span>h: foo<span class="operator">.</span>ui
uic $<span class="operator"><</span> <span class="operator">-</span>o $@
</pre>
<p>You must also remember to add <code>ui_foo.h</code> to your <code>HEADERS</code> (substitute your favorite name).</p>
