I looks like the SetView() of nsFrame will eventually calls PresContext()->PropertyTable()->SetProperty()... It seems to me it is the PresContext() owns the view. And yet, from http://www.mozilla.org/newlayout/doc/gecko-overview.htm it said View is owned by Frame. So can you please tell me which owns the View? PresContext() or Frame()? And how many Views are there per html Document? 1 for the whole document? 5748 nsresult 5749 nsIFrame::SetProperty(nsIAtom* aPropName, 5750 void* aPropValue, 5751 NSPropertyDtorFunc aPropDtorFunc, 5752 void* aDtorData) 5753 { 5754 return PresContext()->PropertyTable()-> 5755 SetProperty(this, aPropName, aPropValue, aPropDtorFunc, aDtorData); 5756 } Thank you. _______________________________________________ dev-tech-layout mailing list [email protected] https://lists.mozilla.org/listinfo/dev-tech-layout
