Hello Geiser,

Sorry to bother you again. I have spend several hours in googling and
digging into the kjsembed source code, tring to figure out how to
expose the C++ object to JS namespace.

The background of this question is soc-kde-scripting project. I have
exposed the KABCore instance mCore as "Contacts" and I found several
interesting things:

1) Only public slot function can be accessed even the JSSecurityPolicy
is set to CapabilityAll. Is this that designed deliberatedly ?

2) To access the addressBook in KABCore, I added the following lines
in KABCore::publishObject() :
KJSEmbedPart *js = KPIM::KJSEngine::instance();
  JSSecurityPolicy::setDefaultPolicy( JSSecurityPolicy::CapabilityAll );
  KJS::Object root = js->addObject(this, "Contacts");
  js->addObject( mAddressBook, root, "addressBook" );

The JS could access Contacts, but complains that the addressBook is
unamed( KAB::AddressBook ). It is recoganized inherited from QObject.

My question is:  How could I expose mAddressBook ? Should I develop a
wrapper class or use JSOpaqueProxy to delegate mAddressBook ? Could
you be kind enough to provide some small examples ?

The same applies to the KOrganizer, I need to expose the object from
libkcal. No idea how to implement this.


Best regards,

Kun Xi
