// frame.h
// Declaration of the CFrame and CMenuBar classes
// The classes declared in this file support SDI (Single Document Interface)
// frames on Win32/Win64 operating systems (not Windows CE). For Windows CE,
// use wceframe.h instead. SDI frames are a simple frame which supports a
// single view window. Refer to mdi.h for frames that support several
// child windows.
// CFrame also includes each of the following classes as members:
// * CReBar for managing the frame's rebar control.
// * CMenuBar for managing the menu inside the rebar.
// * CToolBar for managing the frame's toolbar.
// * CStatusBar for managing the frame's status bar.
// In each case these members are exposed by a GetXXX function, allowing
// them to be accessed or sent messages.
// CFrame is responsible for creating a "frame" window. This window has a
// menu and and several child windows, including a toolbar (usualy hosted
// within a rebar), a status bar, and a view positioned over the frame
// window's non-client area. The "view" window is a seperate CWnd object
// assigned to the frame with the SetView function.
// When compiling an application with these classes, it will need to be linked
// with Comctl32.lib.
// To create a SDI frame application, inherit a CMainFrame class from CFrame.
// Use the Frame sample application as the starting point for your own frame
// applications.
// Refer to the Notepad and Scribble samples for examples on how to use these
// classes to create a frame application.
