QGraphicItem -> No antialiasing



  • Hi,

    I use the QGraphicsView and have a custom QGraphicItem to display some curves. The problem is that I play with the cache mode :

    • DeviceCoordinateCache : Very slow with a lot of curves, but with antialiasing
    • ItemCoordinateCache: Very slow with a lot of curves, but with antialiasing
    • DeviceCoordinateCache : Fast, but without antialiasing !!

    I don't know why I have no antialiasing with DeviceCoordinateCache !

    Here is the kind of graph I try to display : http://www.spectralpixel.com/images/misc/features_sgraph.png
