Thank you Boris. I have been looking at the code for nsViewManager::RenderDisplayListElement(), nsView::Paint(), PresShell::Paint() in Gecko 1.8. But I don't see any where which it walks thru the nsView hierarchy during painting? For the iframe case, it will paint the iframe's nsView and then walk thru its children nsView (the content of iframe, right)? My question is how does iframe content getting paint? Thank you for any more pointers. _______________________________________________ dev-tech-layout mailing list [email protected] https://lists.mozilla.org/listinfo/dev-tech-layout
