C++ (Cpp) notifyTargetAboutAnimValChange示例

示例#1

文件： SVGAnimateElement.cpp 项目： aobzhirov/ChromiumGStreamerBackend

static inline void notifyTargetAndInstancesAboutAnimValChange(SVGElement* targetElement, const QualifiedName& attributeName)
{
    ASSERT(targetElement);
    if (attributeName == anyQName() || !targetElement->inDocument() || !targetElement->parentNode())
        return;

    SVGElement::InstanceUpdateBlocker blocker(targetElement);
    notifyTargetAboutAnimValChange(targetElement, attributeName);

    // If the target element has instances, update them as well, w/o requiring the <use> tree to be rebuilt.
    for (SVGElement* element : targetElement->instancesForElement())
        notifyTargetAboutAnimValChange(element, attributeName);
}
