[webkit-dev] Window or internal frame

I could not seem to find a good way to determine if I needed to create a child frame embedded inside the parent or create a toplevel frame when Frame::createFrame was called. The only solution I found was to check the requesting node and on up int its frameset parents for the frame or iframe etc. Also I could not find the Objective-C implementation in the source tree. Either I'm missing something or this is the way to do it ? Mike
