Detailed Description

This class allows clients to be notified whenever any ModelImport's state has changed.

To use the ImportStateChangedListener class:

from NodeListeners import ImportStateChangedListener

class your-client-class:

def __init__( self, etc. ): ImportStateChangedListener.instance().register( self ) etc.

def onStateChanged( self, modelImport ): process-the-import-node-based-on-state

The client's onStateChanged() method is provided with the ModelImport whose state has changed.

Implementation note: We store a list of weak references to the clients; if we stored strong references, then this class could end up being the only reference to the client, preventing it from being finalized.

#include <class_node_listeners_1_1_import_state_changed_listener.h>
