Hi, Having dug deeper into it, I found JSBindings.cpp. So, now I know CallJS works both ways, basically, we can call JS core code from C++ and vice-versa. But, still I haven't understood how it is being done. Do, we need to make bindings for every C++ function that we call from JS core, something like: static JSValueRef console_setscript(JSContextRef ctx, JSObjectRef /*function*/, JSObjectRef thisObject, size_t /*argumentCount*/, const JSValueRef[] /*arguments*/, JSValueRef* /*exception*/); What will be the best place to do it? Is it possible for soemone to explain me the flow, how we are achieving this. I can see CallJSDlg::callJsFunction() fn. doing some kind of bindings but what exactly is happening and what is the flow. Thanks, newbie. _______________________________________________ webkit-help mailing list webkit-help@lists.webkit.org http://lists.webkit.org/mailman/listinfo/webkit-help
