<p>This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.</p>
<p>Use bool find(const <a href="../qtcore/qstring.html">QString</a>&, <a href="qpixmap.html">QPixmap</a>*) instead.</p>

<h3 class="fn" id="find-2"><a name="find-2"></a><code>[static] </code><span class="type"><a href="qpixmap.html">QPixmap</a></span> *QPixmapCache::<span class="name">find</span>(const <span class="type"><a href="../qtcore/qstring.html">QString</a></span> &<i>key</i>)</h3>
<p>This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.</p>
<p>This is an overloaded function.</p>
<p>Returns the pixmap associated with the <i>key</i> in the cache, or null if there is no such pixmap.</p>
<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 bool find(const <a href="../qtcore/qstring.html">QString</a>&, <a href="qpixmap.html">QPixmap</a>*) instead.</p>
<p>Example:</p>
<pre class="cpp">
<span class="type"><a href="qpixmap.html">QPixmap</a></span><span class="operator">*</span> pp;
<span class="type"><a href="qpixmap.html">QPixmap</a></span> p;
