Document/View architecture support

BestView package comes with a special base class which is intended for Document/View architecture support. The class, CBasePreviewView is declared in two files: BasePreviewView.h and BasePreviewView.cpp . Most of its functionality it inherits from the CorePreviewCallbackWrapper class. The class is declared as:

namespace	 BESTVIEW
{

class CBasePreviewView : public CView, public BESTVIEW::CCorepreviewCallbackWrapper
	{
	public:
	
	DECLARE_DYNCREATE(CBasePreviewView)

	CBasePreviewView();
	virtual ~CBasePreviewView();

	BOOL  PreCreateWindow(CREATESTRUCT&);
	void OnSize(UINT,int,int);
	int OnCreate(LPCREATESTRUCT);
	BOOL OnEraseBkgnd(CDC *);

	void InitCorePreview();

	protected:
	void OnDraw(CDC* pDC);
	DECLARE_MESSAGE_MAP()
	};

} // end namespace BESTVIEW	
		
		

There is only function which is not inherited from MFC CView class: void InitCorePreview(); This function just makes DoInitCorePreview call of the CorePreviewCallbackWrapper class.
