behavior. Next step is to enable the java side in test-first design fashion. A webclient/src_moz/EmbedEventListener.cpp A webclient/src_moz/EmbedEventListener.h - carried over directly from GtkMozEmbed, minus GTK code. M webclient/src_moz/EmbedProgress.cpp - call to NativeBrowserControl::ContentStateChange() to hook up listeners. M webclient/src_moz/Makefile.in - add new EmbedEventListener.cpp file M webclient/src_moz/NativeBrowserControl.cpp M webclient/src_moz/NativeBrowserControl.h - new methods for hooking up listeners.
