    I need showing pictures scaling like drilldown example in qt documents.But I couldnt understand it well.

    Which parts of the example did you not understand? The most interesting methods for you are:
    • ImageItem::hoverEnterEvent()
    • ImageItem::hoverLeaveEvent()
    • ImageItem::setFrame()

    Hover event fires up a forward timeline and leave even fires up a backward timeline. The timeline is connected to aforementioned ImageItem::setFrame() which does the actual scaling.
