Issue 121263

XPropertyChangeListener does not get fired when changing properties, e.g. of an XLayer. The web is full of threads for not using this listener because it doesn’t get fired at all, even on dispose. This could be linked to the bug 61522 which seems to be the same problem. The Events have to get fired on every changes made on the properties.


Sample code C#

    class DrawDocLayerManager : XPropertyChangeListener, XVetoableChangeListener, XPropertyStateChangeListener, XPropertySetInfoChangeListener, XPropertiesChangeListener 
    {       
        private readonly XNameAccess _layerManger;

        public DrawDocLayerManager(XLayerSupplier drwaDoc)
        {
            if (drwaDoc == null)
                throw new ArgumentNullException("drwaDoc", "The XLayerSupplier is null");

            _layerManger = drwaDoc.getLayerManager();
            XIndexAccess xIndexAccess = (XIndexAccess)_layerManger;

            //Add PropertychangeListener to all Layer
            for (int i = 0; i < xIndexAccess.getCount(); i++)
            {
                try
                {
                    XLayer xLayer = (XLayer)xIndexAccess.getByIndex(i).Value;

                    xLayer.addPropertyChangeListener("Name", this);
                    xLayer.addVetoableChangeListener("Name", this);
                    xLayer.addPropertyChangeListener("", this);
                    xLayer.addVetoableChangeListener("", this);

                    ((XPropertySet)xLayer).setPropertyValue("Name", new Any("foo"));

                }
                catch (System.Exception e)
                {
                    Console.WriteLine(e);
                }


            }


        }

        public void disposing(EventObject Source)
        {
             throw new NotImplementedException();
        }

        public void propertiesChange(PropertyChangeEvent[] aEvent)
        {
            throw new NotImplementedException();
        }

        public void propertySetInfoChange(PropertySetInfoChangeEvent evt)
        {
            throw new NotImplementedException();
        }

        public void propertyStateChange(PropertyStateChangeEvent aEvent)
        {
            throw new NotImplementedException();
        }

        public void vetoableChange(PropertyChangeEvent aEvent)
        {
            throw new NotImplementedException();
        }

        public void propertyChange(PropertyChangeEvent evt)
        {
            throw new NotImplementedException();
        }
    }
}
