示例1: AddStateBits
void
nsSVGOuterSVGFrame::Init(nsIContent* aContent,
nsContainerFrame* aParent,
nsIFrame* aPrevInFlow)
{
NS_ASSERTION(aContent->IsSVG(nsGkAtoms::svg),
"Content is not an SVG 'svg' element!");
AddStateBits(NS_STATE_IS_OUTER_SVG |
NS_FRAME_FONT_INFLATION_CONTAINER |
NS_FRAME_FONT_INFLATION_FLOW_ROOT);
// Check for conditional processing attributes here rather than in
// nsCSSFrameConstructor::FindSVGData because we want to avoid
// simply giving failing outer <svg> elements an nsSVGContainerFrame.
// We don't create other SVG frames if PassesConditionalProcessingTests
// returns false, but since we do create nsSVGOuterSVGFrame frames we
// prevent them from painting by [ab]use NS_FRAME_IS_NONDISPLAY. The
// frame will be recreated via an nsChangeHint_ReconstructFrame restyle if
// the value returned by PassesConditionalProcessingTests changes.
SVGSVGElement *svg = static_cast<SVGSVGElement*>(aContent);
