CTabView Class

The CTabView class simplifies the use of the tab control class (CMFCTabCtrl) in applications that use MFC's document/view architecture.

class CTabbedView : public CView

Name

Description

CTabView::AddView

Adds a new view to the tab control.

CTabView::FindTab

Returns the index of the specified view in the tab control.

CTabView::GetActiveView

Returns a pointer to the currently active view

CTabView::GetTabControl

Returns a reference to the tab control associated with the view.

CTabView::RemoveView

Removes the view from the tab control.

CTabView::SetActiveView

Makes a view active.

Name

Description

CTabView::IsScrollBar

Called by the framework when creating a tab view to determine whether the tab view has a shared horizontal scroll bar.

CTabView::OnActivateView

Called by the framework when the tab view is made active or inactive.

This class makes it easy to put a tabbed view into a document/view application. CTabView is a CView-derived class that contains an embedded CMFCTabCtrl object. CTabView handles all messages required to support the CMFCTabCtrl object. Simply derive a class from CTabView and plug it into your application, then add CView-derived classes by using the AddView method. The tab control will display those views as tabs.

For example, you might have a document that can be represented in different ways: as a spreadsheet, a chart, an editable form, and so on. You can create individual views drawing the data as needed, insert them into your CTabView-derived object and have them tabbed without any additional coding.

TabbedView Sample: MFC Tabbed View Application illustrates usage of CTabView.

The following example shows how CTabView is used in the TabbedView sample.

class CTabbedViewView : public CTabView
{
protected: // create from serialization only
	CTabbedViewView();
	DECLARE_DYNCREATE(CTabbedViewView)

// Attributes
public:
	CTabbedViewDoc* GetDocument();

// Operations
public:

// Overrides
	public:
	virtual void OnDraw(CDC* pDC);  // overridden to draw this view
	virtual BOOL PreCreateWindow(CREATESTRUCT& cs);
	protected:
	virtual BOOL OnPreparePrinting(CPrintInfo* pInfo);
	virtual void OnBeginPrinting(CDC* pDC, CPrintInfo* pInfo);
	virtual void OnEndPrinting(CDC* pDC, CPrintInfo* pInfo);

	BOOL IsScrollBar () const
	{
		return TRUE;
	}

// Implementation
public:
	virtual ~CTabbedViewView();
#ifdef _DEBUG
	virtual void AssertValid() const;
	virtual void Dump(CDumpContext& dc) const;
#endif

protected:
	afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
	afx_msg BOOL OnEraseBkgnd(CDC* pDC);
	afx_msg void OnContextMenu(CWnd*, CPoint point);
	afx_msg void OnFilePrintPreview();

	DECLARE_MESSAGE_MAP()
};
