<h2>Detailed Description</h2>
<p>The QPixmapCache::Key class can be used for efficient access to the <a href="qpixmapcache.html">QPixmapCache</a>.</p>
<p>Use <a href="qpixmapcache.html#insert">QPixmapCache::insert</a>() to receive an instance of Key generated by the pixmap cache. You can store the key in your own objects for a very efficient one-to-one object-to-pixmap mapping.</p>
