Because QList make use of much more stuff in QListData that is not template type (hence, not generated for every types) However, I beleive it is possible to do the same optimisation for movable type within QVector, if we want to. _______________________________________________ Qt5-feedback mailing list [email protected] http://lists.qt.nokia.com/mailman/listinfo/qt5-feedback
