Indeed. Paint() calls nsLayoutUtils::PaintFrame with the root frame of the subtree to paint. PaintFrame() does BuildDisplayListForStackingContext(), and building the display list is what walks the frame tree, because some of the display items walk kids. See, for example, nsHTMLContainerFrame::DisplayTextDecorationsAndChildren. -Boris _______________________________________________ dev-tech-layout mailing list [email protected] https://lists.mozilla.org/listinfo/dev-tech-layout
