示例1: layout
void RenderSVGRoot::layout()
{
ASSERT(needsLayout());
// Arbitrary affine transforms are incompatible with LayoutState.
view()->disableLayoutState();
LayoutRepainter repainter(*this, checkForRepaintDuringLayout() && selfNeedsLayout());
int oldWidth = width();
calcWidth();
int oldHeight = height();
calcHeight();
SVGSVGElement* svg = static_cast<SVGSVGElement*>(node());
setWidth(static_cast<int>(width() * svg->currentScale()));
setHeight(static_cast<int>(height() * svg->currentScale()));
calcViewport();
// RenderSVGRoot needs to take special care to propagate window size changes to the children,
// if the outermost <svg> is using relative x/y/width/height values. Hence the additonal parameters.
layoutChildren(this, selfNeedsLayout() || (svg->hasRelativeValues() && (width() != oldWidth || height() != oldHeight)));
repainter.repaintAfterLayout();
view()->enableLayoutState();
setNeedsLayout(false);
