    Default why bitBlt() deleted in Qt4

    I want to use bitBlt in Qt4,but I find it deleted by "#ifdef QT3_SUPPORT" by default.

    Is it replaced by RaW bitmap operation with the same efficiency.??

    Thanks.

    QPainter::drawPixmap is the suggested alternative. It should be the same speed when there is no rotation matrix or similar that alters the image before blitting.
    It's nice to be important but it's more important to be nice.
