There was no QVector in Qt3. QValueVector and early Qt 4 QVector didn't support overalignment. Sometime along Qt 4.x, I added the necessary support and it has been carried over ever since. I just never bothered to write it down in the docs. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
