CODController Class
class CODController: public MvcController
The controller handles user interaction and keeps track of UI state information. Messages are forwarded to the controller from the viewport. The controller inherits message map processing from CWnd, but it does not actually have its own window handle. Instead, the controller is plugged into the window that contains the viewport so that it can process messages for the viewport.The controller changes state and updates the viewport as it receives events. When a user interaction task is complete, the controller typically generates a command object and passes it to the model. A set of virtual Execute methods take care of command creation and execution.
The controller keeps track of the currently selected set of components. Many of the tasks that are performed by the controller act upon the current selection. The OnSelectionChange is called whenever the current selection changes.
The controller contains a CODDropTarget object that is used to implement OLE drag and drop. The CreateDropTarget method creates the drop target object and registers the viewport with it.
Defined in: OdController.h
