<h2>Detailed Description</h2>
<p>The Q3FileIconProvider class provides icons for <a href="q3filedialog.html">Q3FileDialog</a> to use.</p>
<p>By default Q3FileIconProvider is not used, but any application or library can subclass it, reimplement <a href="q3fileiconprovider.html#pixmap">pixmap</a>() to return a suitable icon, and make all <a href="q3filedialog.html">Q3FileDialog</a> objects use it by calling the static function <a href="q3filedialog.html#setIconProvider">Q3FileDialog::setIconProvider</a>().</p>
<p>It is advisable to make all the icons that Q3FileIconProvider returns be the same size or at least the same width. This makes the list view look much better.</p>
<p>See also <a href="q3filedialog.html">Q3FileDialog</a>.</p>

<h2>Member Function Documentation</h2>
<a name="//apple_ref/cpp/instm/Q3FileIconProvider/Q3FileIconProvider"></a>
<h3 class="fn"><a name="Q3FileIconProvider"></a>Q3FileIconProvider::Q3FileIconProvider ( <a href="qobject.html">QObject</a> * <i>parent</i> = 0, const char * <i>name</i> = 0 )</h3>
<p>Constructs an empty file icon provider called <i>name</i>, with the parent <i>parent</i>.</p>
<a name="//apple_ref/cpp/instm/Q3FileIconProvider/pixmap"></a>
<h3 class="fn"><a name="pixmap"></a>const <a href="qpixmap.html">QPixmap</a> * Q3FileIconProvider::pixmap ( const <a href="qfileinfo.html">QFileInfo</a> & <i>info</i> ) <tt> [virtual]</tt></h3>
<p>Returns a pointer to a pixmap that should be used to signify the file with the information <i>info</i>.</p>
<p>If pixmap() returns 0, <a href="q3filedialog.html" class="compat">Q3FileDialog</a> draws the default pixmap.</p>
<p>The default implementation returns particular icons for files, directories, link-files and link-directories. It returns a blank "icon" for other types.</p>
<p>If you return a pixmap here, it should measure 16x16 pixels.</p>
