<hr><a name="details"></a><h2>Detailed Description</h2>
 
<p> The TQFileIconProvider class provides icons for <a href="tqfiledialog.html">TQFileDialog</a> to
use.
<p> 
<p> By default TQFileIconProvider is not used, but any application or
library can subclass it, reimplement <a href="#pixmap">pixmap</a>() to return a suitable
icon, and make all TQFileDialog objects use it by calling the static
function <a href="tqfiledialog.html#setIconProvider">TQFileDialog::setIconProvider</a>().
<p> It is advisable to make all the icons that TQFileIconProvider 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="tqfiledialog.html">TQFileDialog</a> and <a href="misc.html">Miscellaneous Classes</a>.

<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQFileIconProvider"></a>TQFileIconProvider::TQFileIconProvider ( <a href="tqobject.html">TQObject</a>&nbsp;*&nbsp;parent = 0, const&nbsp;char&nbsp;*&nbsp;name = 0 )
</h3> Constructs an empty file icon provider called <em>name</em>, with the
parent <em>parent</em>.

<h3 class=fn>const&nbsp;<a href="ntqpixmap.html">TQPixmap</a>&nbsp;* <a name="pixmap"></a>TQFileIconProvider::pixmap ( const&nbsp;<a href="tqfileinfo.html">TQFileInfo</a>&nbsp;&amp;&nbsp;info )<tt> [virtual]</tt>
</h3>
Returns a pointer to a pixmap that should be used to
signify the file with the information <em>info</em>.
<p> If <a href="#pixmap">pixmap</a>() returns 0, <a href="tqfiledialog.html">TQFileDialog</a> draws the default pixmap.
<p> The default implementation returns particular icons for files, directories,
link-files and link-directories. It returns a blank "icon" for other types.
<p> If you return a pixmap here, it should measure 16x16 pixels.
