[webkit-help] About insert custom-defined object into JavaScript Enviroment in WebKit's Cairo-port

[yanghb]

I want to insert custom-defined Objects / functions into JavaScript
Enviroment in Webkit's Cairo-port. The only way I can find by now is
to use JSObject* methods.

the IWebView::windowScriptObject() method return an E_NOTIMPL error.

besides, the KVC method setValue:forKey: seems not be available to COM
Interface.

So, the JSObject methods are the only way in Cairo-port Webkit, is it ?
