示例1: swap

{
    using std::swap;
    RefPtrWillBeRawPtr<Frame> oldFrame = toCoreFrame(this);

    // All child frames must be detached first.
    oldFrame->detachChildren();

    // If the frame has been detached during detaching its children, return
    // immediately.
    // FIXME: There is no unit test for this condition, so one needs to be
    // written.
    if (!oldFrame->host())
        return false;

    if (m_parent) {
        if (m_parent->m_firstChild == this)

    }

    // Finally, clone the state of the current Frame into one matching
    // the type of the passed in WebFrame.
    // FIXME: This is a bit clunky; this results in pointless decrements and
    // increments of connected subframes.
    FrameOwner* owner = oldFrame->owner();

                ownerElement->setWidget(toLocalFrame(newFrame)->view());
