    Default What should be the fastest QList operation?

    Hello!

    This is a quesiton similar to this old one: http://www.qtcentre.org/threads/5927...ation?p=263368

    What should be the fastest operation to make? (provided that the QList is at least a little big, lets say 100 items or more)


    1. QList::reserve()
    2. QList::resize()
    3. QList::insertAt()

    vs.

    1. QList::reserve()
    2. QList::append() repeatedly, till QList::size() == reserved
    May the Lord be with you. Always.

    First of all there is no resize() in QList. Second of all when appending QList behaves the same was as QVector. Third of all, RTFM: http://doc.qt.digia.com/qq/qq19-containers.html
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.

    Oh, my mistake! Sorry! :S (I guess I did a confusion because the source code from which I took the question has both a QVector and a QList implemented)

    Well, that was a documentation I never heard about; thanks for the link! (Btw wouldn't there be any Qt5 changes that could invalidate part of this article?)

    Thanks,
