      • addGraphListener

        public void addGraphListener​(GraphListener l)
        Add a graph listener to the model. Graph listeners are notified with a GraphEvent any time the graph is modified.
        Specified by:
        addGraphListener in interface GraphModel
      • dispatchGraphEvent

        public void dispatchGraphEvent​(GraphEvent e)
        Send an graph event to all of the graph listeners. This allows manual control of sending graph graph events, or allows the user to send a STRUCTURE_CHANGED after some inner-loop operations.

        This method furthermore ensures that all graph events are dispatched in the event thread.

        dispatchGraphEvent in interface GraphModel

      • removeGraphListener

        public void removeGraphListener​(GraphListener l)
        Remove the given listener from this graph model. The listener will no longer be notified of changes to the graph.
        Specified by:
        removeGraphListener in interface GraphModel
      • setDispatchEnabled

        public void setDispatchEnabled​(boolean val)
        Turn on/off all event dispatches from this graph model, for use in an inner-loop algorithm. When turning dispatch back on again, if the client has made changes that listeners should know about, he should create an appropriate STRUCTURE_CHANGED and dispatch it using the dispatchGraphEvent() method.
        Specified by:
        setDispatchEnabled in interface GraphModel
