示例1: styleDidChange
void RenderSVGGradientStop::styleDidChange(StyleDifference diff, const RenderStyle* oldStyle)
{
RenderObject::styleDidChange(diff, oldStyle);
if (!diff.hasDifference())
return;
// <stop> elements should only be allowed to make renderers under gradient elements
// but I can imagine a few cases we might not be catching, so let's not crash if our parent isn't a gradient.
SVGGradientElement* gradient = gradientElement();
if (!gradient)
return;
RenderObject* renderer = gradient->renderer();
if (!renderer)
return;
RenderSVGResourceContainer* container = toRenderSVGResourceContainer(renderer);
container->removeAllClientsFromCache();
}示例2: clientStyleChanged
void SVGResourcesCache::clientStyleChanged(LayoutObject* layoutObject, StyleDifference diff, const ComputedStyle& newStyle)
{
ASSERT(layoutObject);
ASSERT(layoutObject->node());
ASSERT(layoutObject->node()->isSVGElement());
if (!diff.hasDifference() || !layoutObject->parent())
return;
// In this case the proper SVGFE*Element will decide whether the modified CSS properties require a relayout or paintInvalidation.
if (layoutObject->isSVGResourceFilterPrimitive() && !diff.needsLayout())
return;
// Dynamic changes of CSS properties like 'clip-path' may require us to recompute the associated resources for a layoutObject.
// FIXME: Avoid passing in a useless StyleDifference, but instead compare oldStyle/newStyle to see which resources changed
// to be able to selectively rebuild individual resources, instead of all of them.
if (layoutObjectCanHaveResources(layoutObject)) {
SVGResourcesCache* cache = resourcesCacheFromLayoutObject(layoutObject);
cache->removeResourcesFromLayoutObject(layoutObject);
cache->addResourcesFromLayoutObject(layoutObject, newStyle);
}
LayoutSVGResourceContainer::markForLayoutAndParentResourceInvalidation(layoutObject, false);
}
