<h2>Member Function Documentation</h2>
<h3 class="fn"><a name="erase-2"></a>void QMap::erase ( const Key & <i>key</i> )</h3>
<p>Use remove(<i>key</i>) instead.</p>
<h3 class="fn"><a name="insert-2"></a><a href="qmap-iterator.html">iterator</a> QMap::insert ( const Key & <i>key</i>, const T & <i>value</i>, bool <i>overwrite</i> )</h3>
<p>Use the two-argument <a href="qmap.html#insert">insert</a>() overload instead. If you don't want to overwrite, call <a href="qmap.html#contains">contains</a>() beforehand.</p>
<p>For example, if you have code like</p>
<pre><font color="#404040"> QMap<QString, int> map;
...
map.insert("delay", 30000, false);</font></pre>
<p>you can rewrite it as</p>
<pre> QMap<QString, int> map;
...
if (!map.contains("delay"))
map.insert("delay", 30000);</pre>
<h3 class="fn"><a name="remove-2"></a><a href="qmap-iterator.html">iterator</a> QMap::remove ( <a href="qmap-iterator.html">iterator</a> <i>it</i> )</h3>
<p>Use erase(<i>it</i>) instead.</p>
<a name="//apple_ref/cpp/instm/QMap/replace"></a>
<h3 class="fn"><a name="replace"></a><a href="qmap-iterator.html">iterator</a> QMap::replace ( const Key & <i>key</i>, const T & <i>value</i> )</h3>
<p>Use <a href="qmap.html#remove">remove</a>() then <a href="qmap.html#insert">insert</a>().</p>
