MDI +// (Multiple Document Interface) frames host one or more child windows. The +// child windows hosted by a MDI frame can be different types. For example, +// some MDI child windows could be used to edit text, while others could be +// used to display a bitmap. Four classes are defined here to support MDI +// frames: + + +// 1) CMDIFrame. This class inherits from CFrame, and adds the functionality +// required by MDI frames. It keeps track of the MDI children created and +// destroyed, and adjusts the menu when a MDI child is activated. Use the +// AddMDIChild function to add MDI child windows to the MDI frame. Inherit +// from CMDIFrame to create your own MDI frame. +// +// 2) CMDIChild: All MDI child windows (ie. CWnd classes) should inherit from +// this class. Each MDI child type can have a different frame menu. + +// Use the MDIFrame generic application as the starting point for your own MDI +// frame applications. +// Refer to the MDIDemo sample for an example on how to use these classes to +// create a MDI frame application with different types of MDI child windows. + + +#ifndef _WIN32XX_MDI_H_ +#define _WIN32XX_MDI_H_ + +#include "frame.h" +#include <vector> + + + +namespace Win32xx +{ + class CMDIChild;
