LESSON 29

Overview

of Previous Lesson(s)

Over View

• SDI programs

– The Application Wizard can generate single-document interface (SDI) applications that work

with a single document and a single view

• MDI programs

– Multiple - document interface (MDI) programs that

can handle multiple documents with multiple

views simultaneously

3

Over View

• The application object

– A program can have only one application object

– This is defined automatically by the Application

Wizard at global scope

• Document objects

– A document class object stores application - specific data, and a view class object displays the

contents of a document object

4

Over View

• The View Object

– Each view object can provide a different presentation of the document data or a subset of

the same data

• Windows Frame Object

– Each frame window object stores a pointer to the

currently active view object

5

Over View

• Document templates

– A document template class object is used to tie

together a document, a view, and a window

– For an SDI application, a CSingleDocTemplate

class does this

– For an MDI application, the CMultiDocTemplate

class is used

Over View…

• Message Handlers

– MFC provides functions to handle just the individual messages that we are interested in and

to ignore the rest

• Message Map

– A message map for a class is a table of member

functions that handle Windows messages

bounded by a couple of macros
