CMvcController Class

class CMvcController: public IEventRouter

This template is used to define controller classes that interact with a given type of model and viewport. The model class argument defines the type of model that this controller interacts with. The viewport class argument defines the type of viewport that this controller interacts with.

This class inherits the IMvcController_T template interface, and passes the model and viewport class arguments to that template.

Controllers support the  IEventListener interface and also provide a mechanism for aggregating event listeners. The  AddListener and  RemoveListener methods allow event listener objects to be added to the controller. The controller then gives all of its listeners a chance to handle events that it receives.

Defined in: MvcController.h
