Register specific node type created

[Arvid Schneider]

How would I create a callback that fires when a specific node type is created?

I know about: MDGMessage.addNodeAddedCallback( function )

but that registers any node created. I want to limit that. 

Someone an idea?

Filter in the callback for your specific node type?

MCallbackId MDGMessage::addNodeAddedCallback ( MMessage::MNodeFunction func,

const MString & nodeType = "dependNode",

void * clientData = NULL,

MStatus * ReturnStatus = NULL  

)

Parameters:

[in] nodeType Type of node that will trigger the callback

[in] clientData User defined data passed to the callback function

[out] ReturnStatus status code

There is a nodeType argument so that will help you to get what you trying.
