示例1: updateDescendantDependentFlagsForEntireSubtree
// The descendant-dependent flags system is badly broken because we clean dirty
// bits in upward tree walks, which means we need to call updateDescendantDependentFlags
// at every node in the tree to fully clean all the dirty bits. While we'll in
// the process of fixing this issue, updateDescendantDependentFlagsForEntireSubtree
// provides a big hammer for actually cleaning all the dirty bits in a subtree.
//
// FIXME: Remove this function once the descendant-dependent flags system keeps
// its dirty bits scoped to subtrees.
void updateDescendantDependentFlagsForEntireSubtree(PaintLayer& layer)
{
layer.updateDescendantDependentFlags();
for (PaintLayer* child = layer.firstChild(); child; child = child->nextSibling())
updateDescendantDependentFlagsForEntireSubtree(*child);
}
示例2: paintLayers
static void paintLayers(PaintLayer& layer, SimDisplayItemList& displayList)
{
if (layer.isAllowedToQueryCompositingState() && layer.compositingState() == PaintsIntoOwnBacking) {
CompositedLayerMapping* mapping = layer.compositedLayerMapping();
GraphicsLayer* graphicsLayer = mapping->mainGraphicsLayer();
if (graphicsLayer->hasTrackedPaintInvalidations()) {
ContentLayerDelegate* delegate = graphicsLayer->contentLayerDelegateForTesting();
delegate->paintContents(&displayList, WebRect(0, 0, layer.size().width(), layer.size().height()));
graphicsLayer->resetTrackedPaintInvalidations();
}
}
for (PaintLayer* child = layer.firstChild(); child; child = child->nextSibling())
paintLayers(*child, displayList);
}
