As far as I can see, you do not interact with the Qt API and thus need QList for them, or am I missing something? QModelIndex is too large, and thus you'll allocate every item in the list on the heap. int is, on 64bit, too small and thus you waste space (factor of 2).</p></pre>

You're right about int though. QIdentityProxyModel has the same problem then.
You're right about this being internal.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I'll change it to QVector for both, although I maintain that the QPMI one was fine ;)</p></pre>
