<p> This page documents the <em>User Interface Compiler</em> for the Qt GUI
toolkit. The <em>uic</em> reads a user interface definition
(.ui) file in XML as generated by <a href="designer-manual.html">Qt
Designer</a> and creates corresponding C++ header or source files.
It can also generate an image file to embed raw image data in C++
source code.
<p> <h2> Options
</h2>
<a name="1"></a><p> <h3> File Generation Options
</h3>
<a name="1-1"></a><p> Generate declaration:
<pre>
uic  [options]  &lt;file&gt;
</pre>
 
<p> Generate implementation:
<pre>
uic  [options] -impl &lt;headerfile&gt; &lt;file&gt;
</pre>
 
<ul>
<li> &lt;headerfile&gt; - name of the declaration file
</ul>
<p> Generate image collection:
<pre>
uic  [options] -embed &lt;project&gt; &lt;image1&gt; &lt;image2&gt; &lt;image3&gt; ...
</pre>
 
<ul>
<li> &lt;project&gt; - project name
<li> &lt;image[0..n]&gt; - image files
</ul>
<p> For convenience, <em>uic</em> can also generate declaration or
implementation stubs for subclasses.
<p> Generate subclass declaration:
<pre>
uic  [options] -subdecl &lt;classname&gt; &lt;headerfile&gt; &lt;file&gt;
</pre>
 
<ul>
<li> &lt;classname&gt; - name of the subclass to generate
<li> &lt;headerfile&gt; - declaration file of the <b>baseclass</b>
</ul>
<p> Generate subclass implementation:
<pre>
uic  [options] -subimpl &lt;classname&gt; &lt;headerfile&gt; &lt;file&gt;
</pre>
 
<ul>
<li> &lt;classname&gt; - name of the subclass to generate
<li> &lt;headerfile&gt; - declaration file of the <b>subclass</b>
</ul>
<p> <h3> General Options
</h3>
<a name="1-2"></a><p> <ul>
<li> <tt>-o file</tt> - write output to 'file' rather than to stdout.
<li> <tt>-nofwd</tt> - omit forward declarations of custom classes in the
generated header file. This is necessary if typedef classes are used.
<li> <tt>-tr func</tt> - use <tt>func(sourceText, comment)</tt> rather than
trUtf8(sourceText, comment) for <a href="i18n.html#internationalization">internationalization</a>.
<li> <tt>-pch file</tt> - add <tt>#include "file"</tt> as the first statement in the implementation file.
</ul>
<p> <h2> Usage
</h2>
<a name="2"></a><p> <em>uic</em> is almost always invoked by <tt>make (1)</tt>, rather than by hand.
<p> Here are useful makefile rules if you only use GNU make:
<pre>
    %.h: %.ui
        uic $&lt; -o $@

    %.cpp: %.ui
        uic -impl $*.h $&lt; -o $@
</pre>
 
If you want to write portably, you can use individual rules of the
following form:
<pre>
    NAME.h: NAME.ui
        uic $&lt; -o $@

    NAME.cpp: NAME.ui
        uic -impl $*.h $&lt; -o $@
</pre>
 
You must also remember to add <tt>NAME.cpp</tt> to your SOURCES (substitute
your favorite name) variable and <tt>NAME.o</tt> to your OBJECTS variable.
<p> (While we prefer to name our C++ source files .cpp, the <em>uic</em> doesn't
care, so you can use .C, .cc, .CC, .cxx or even .c++ if you prefer.)
