Our plugin uses carbon event to implement it:

Following is the function the plugin called to install event handler

        m_TrackingHandler = ::NewDragTrackingHandlerUPP( MyDragTrackingHandler
);

        m_ReceiverHandler = ::NewDragReceiveHandlerUPP( MyDragReceiveHandler );


        InstallTrackingHandler( m_TrackingHandler,GraphicsPort,this );

        InstallReceiveHandler( m_ReceiverHandler,GraphicsPort,this );



In the event handler for drag and drop, function returns noErr if event is
processed.


OSErr MyDragTrackingHandler( DragTrackingMessage message,WindowRef
theWindow,void * handlerRefCon,DragRef theDrag)

{
        .......
        return noErr;
}


OSErr MyDragReceiveHandler ( WindowRef theWindow,void * handlerRefCon,DragRef
theDrag)

{
        .......
        return noErr;
}
