Execute, responsible for switching between View, base class is Caknappui and CaknViewAppui
4) View: Responsible for display, update by model provides status to View VIEW inherits from ccoecontrol classes or
CAKNDIALOG class, also have CaknView classes
PS: Model / Engine: Usually implemented in its own class library, it packages the function of the application, handles various data permanent storage and algorithms
Summary: The application framework is responsible for creating Application, and the Application constructs documentation, the document is created again, and AppUI creates and owns it.
Model and views.
