    • TLcdModelChangedEventSupport

      public TLcdModelChangedEventSupport(ILcdModel aModel)
      Constructs a new TLcdModelChangedEventSupport for the given model.

      The model listeners of the specified model cannot be accessed directly by this object; only listeners that are explicitly registered on this object by means of the addModelListener(ILcdModelListener) method are notified of model changes.

      Parameters:
      aModel - the model for which the TLcdModelChangedEvent objects will be handled.

    • fireCollectedModelChanges

      public void fireCollectedModelChanges()
      Fires a TLcdModelChangedEvent that contains all the collected selection changes.

    • elementAdded

      public void elementAdded(Object aObject, int aEventMode)
      Takes care of firing the model event after having added an Object to the model.
      Parameters:
      aObject - the Object that has been added to the model.
      aEventMode - the mode for sending out the model event. This can be ILcdFireEventMode.FIRE_NOW, ILcdFireEventMode.LATER or ILcdFireEventMode.NO_EVENT.
