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  

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.

[!code-cppNVC_MFC_TabbedView#1]

Header: afxTabView.h

Adds a view to the tab control.

int AddView(
    CRuntimeClass* pViewClass,  
    const CString& strViewLabel,  
    int iIndex=-1,  
    CCreateContext* pContext=NULL);

[in] pViewClass
A pointer to a runtime class of the inserted view.

[in] strViewLabel
Specifies the tab's text.

[in] iIndex
Specifies the zero-based position at which to insert the view. If the position is -1 the new tab is inserted at the end.

[in] pContext
A pointer to the CCreateContext of the view.

A view index if this method succeeds. Otherwise, -1.

Call this function to add a view to the tab control that is embedded in a frame.

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

int FindTab(HWND hWndView) const;  

[in] hWndView
The handle of the view.

The index of the view if it is found; otherwise, -1.

Call this function to retrieve the index of a view that has a specified handle.

Returns a pointer to the currently active view.

CView* GetActiveView() const;  

A valid pointer to the active view, or NULL if there is no active view.

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

DECLARE_DYNCREATE CMFCTabCtrl& GetTabControl();

A reference to the tab control associated with the view.

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

virtual BOOL IsScrollBar() const;  

TRUE if the tab view should be created together with a shared scroll bar. Otherwise, FALSE.

The framework calls this method when a CTabView object is being created.

Override the IsScrollBar method in a CTabView-derived class and return TRUE if you want to create a view that has a shared horizontal scroll bar.

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

virtual void OnActivateView(CView* view);

[in] view
A pointer to the view.

The default implementation does nothing. Override this method in a CTabView-derived class to process this notification.

Removes the view from the tab control.

BOOL RemoveView(int iTabNum);

[in] iTabNum
The index of the view to remove.

The index of the removed view if this method succeeds. Otherwise -1.

Makes a view active.

BOOL SetActiveView(int iTabNum);

[in] iTabNum
The zero-based index of the tab view.

TRUE if the specified view was made active, FALSE if the view's index is invalid.
