Usage: you can reimplement this interface by deriving the supplied CATExtIModelEvents adapter class.
interface CATIModelEvents
Interface that makes components communicate with their visualization, that is their graphical
representations.
Role:
As the model world and the visualization world are independent, every action (ie that a geometry modification)
performed by one object or by any command should trigger
a visualization update (when necessary). The way to warn the visualization world is based onto
visualization events and a send/receive mechanism. And the management of the visualization events
is done by this interface: how one object can be connected to (or disconnected from)
another object, how sending
a visualization event?
BOA information: this interface CANNOT be implemented using the BOA (Basic Object Adapter). To know more about the BOA, refer to the CAA Encyclopedia home page. Click Middleware at the bottom left, then click the Object Modeler tab page. Several articles deal with the BOA.
