<h2>Member Function Documentation</h2>

<h3 class="fn"><a name="find-2"></a><a href="qpixmap.html">QPixmap</a> * QPixmapCache::find ( const <a href="qstring.html">QString</a> & <i>key</i> ) <tt> [static]</tt></h3>

<p>This is an overloaded member function, provided for convenience. It behaves essentially like the above function.</p>
31
<p>Returns the pixmap associated with the <i>key</i> in the cache, or null if there is no such pixmap.</p>
32
<p><b>Warning:</b> If valid, you should copy the pixmap immediately (this is fast). Subsequent insertions into the cache could cause the pointer to become invalid. For this reason, we recommend you use find(const <a href="qstring.html">QString</a>&, <a href="qpixmap.html">QPixmap</a>&) instead.</p>
