backward-compatibility now.

I&#39;ve written a small C++ library to provide a simplified API to make sc=

In several places, I create a QList&lt;SomeObject*&gt; and return that, lik=

QList&lt;Document*&gt; documents() const;<br>

Now the Document* objects apparently aren&#39;t deleted when the list go ou=

Is there a generally &quot;right&quot; way of handling this situation?<br>
