MFC Workshop:: Intro To The Document/View Architecture

The document describes the MFC document/view architecture which provides an easy way to save objects and a consistent method for drawing to screens and printing. It discusses the key classes - Document stores application data, View displays the document and acts as an intermediary, Frame window contains views and controls the UI, and Application manages documents and messaging. Applications can be single document (SDI) or multiple document (MDI) and AppWizard and ClassWizard help generate the classes and code.

MFC Workshop:

Intro to the Document/View


Architecture
What is Doc/View?
• The central concept to MFC
• Provides an easy method for saving or
archiving objects
• Takes the pain out of printing - uses the
same code that’s used to draw to the screen
• A possible downfall for apps that want
MFC, but not Doc/View
Application Framework
The Document
• Derived from CDocument
• Controls application data
– provides a generic interface that encapsulates
data
• Loads and stores data through serialization
(saving objects to disk)
The View
• Attached to the document
• Acts as an intermediary between the
document and the user
• Derived from CView
• Document/View Relationship is One-to-
Many.
– Data can be represented multiple ways
The Main Frame Window
• The main, outermost window of the
application
• Contains the views in its client area
• Displays and controls the title bar, menu
bar, system menu, borders, maximize and
minimize buttons, status bar, and tool bars
The Application Object
• We have already discussed CWinApp
– Calls WinMain, contains main thread,
initializes and cleans up application, and
dispatches commands to other objects
• In Doc/View it manages the list of
documents, and sends messages to the
frame window and views
SDI or MDI?
• SDI - Single Document Interface
– Notepad

• MDI - Multiple Document Interface


– Word, Excel, etc.
AppWizard and ClassWizard
• AppWizard is like the Wizards in Word
– Gives a starting point for an application
• Derives the four classes for you
– SDI, MDI (even dialog, or non-Doc/View)
• ClassWizard helps you expand your
AppWizard generate application
– ex. Automatically generates message maps
