The application PhilemonEventTriggerSupport adds EventModel to the VA Smalltalk. Features include:

• adds Object>>when: anEventNameSymbol send: aSelectorSymbol to: anObject
• adds Object>>asValue returning a EventValueHolder that sends notifications on value change
• adds EventModel, EventValueHolder and InterfaceAdaptor
• policy based change notification

Ideas are based on the VisualWorks triggerEvent: mechanism.
