Hi dNafigator,
Thanks a lot. I get it done. My previous compile error is due to
the miss of "nsIWebProgress.h", I simple include it and get it
compiled.
You have very detailed explanation on how to use these macros,
great! I guess they are done in a slightly different way in mozembed
in the .cpp part. The code is using NS_IMPL_ISUPPORT[#] macro.
Seems the semantic of Documentloaded() is for subframe, I suggest
the document of that function be refined, I don't know how to do that
change for the code base document, Boris, any help on that part?
