    <p>I've looked at similar problems but I simply can not see what is going wrong. I've tried <strong>::const_iterator</strong> as well. But gcc will not compile either way.</p> <p>it's about : i = allFunctions.erase(i);</p> <pre><code>void removeEventListener(const std::string &amp;type, function listener){ if(!hasEventListener(type)) return; std::map&lt;int, std::list&lt;function&gt; &gt; &amp;allFunctions = eventHandlerList[type]; std::map&lt;int, std::list&lt;function &gt; &gt;::iterator i; for(i=allFunctions.begin(); i!=allFunctions.end(); ++i) { i-&gt;second.remove(listener); if(i-&gt;second.empty()) { i = allFunctions.erase(i); } } if(allFunctions.empty()) eventHandlerList.erase(type); } </code></pre> <p>error with const_iterator:</p> <pre><code> Error: passing const std::list&lt;void (*)(const st::event::Event&amp;)&gt; as this argument of void std::list&lt;_Tp, _Alloc&gt;::remove(const value_type&amp;) [with _Tp = void (*)(const st::event::Event&amp;), _Alloc = std::allocator&lt;void (*)(const st::event::Event&amp;)&gt;, std::list&lt;_Tp, _Alloc&gt;::value_type = void (*)(const st::event::Event&amp;)] discards qualifiers [-fpermissive] Error: no matching function for call to std::map&lt;int, std::list&lt;void (*)(const st::event::Event&amp;)&gt; &gt;::erase(std::map&lt;int, std::list&lt;void (*)(const st::event::Event&amp;)&gt; &gt;::const_iterator&amp;) </code></pre> <p>error with iterator:</p> <pre><code>no match for operator= in i = (&amp; allFunctions)-&gt;std::map&lt;_Key, _Tp, _Compare, _Alloc&gt;::erase [with _Key = int, _Tp = std::list&lt;void (*)(const st::event::Event&amp;)&gt;, _Compare = std::less&lt;int&gt;, _Alloc = std::allocator&lt;std::pair&lt;const int, std::list&lt;void (*)(const st::event::Event&amp;)&gt; &gt; &gt;, std::map&lt;_Key, _Tp, _Compare, _Alloc&gt;::iterator = std::_Rb_tree_iterator&lt;std::pair&lt;const int, std::list&lt;void (*)(const st::event::Event&amp;)&gt; &gt; &gt;](i) </code></pre> <p>Any suggestions?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
