MFC Doc/View uses Observer Pattern

Answer / nilavu

It uses main three patterns,
Singleton pattern - Application object(CWinApp & its
derived classes)
Bridge pattern - Serialization
Observer patten - Document/View Architecture

If we dig deeper into the MFC classes, it may use some
other patterns also.

Answer / babu

It uses the chain of responsibility as well. Whenever a
message is not handled by a window it is propogated to its
parent until it reaches default window procedure.

Answer / babu

Bridge pattern is used in the view class as well. If you
look at the OnDraw function, it is used to render the
output to either monitor or printer depending upon the
device context being used.
