CDockBar

class CDockBar 派生于 public CControlBar

他的函数有：

DECLARE_DYNAMIC(CDockBar)

// Construction

public:

/* explicit */ CDockBar(BOOL bFloating = FALSE); // TRUE if attached to CMiniDockFrameWnd

virtual BOOL Create(CWnd* pParentWnd, DWORD dwStyle, UINT nID);

// Attributes

BOOL m_bFloating;

virtual BOOL IsDockBar() const;

int GetDockedCount() const;

virtual int GetDockedVisibleCount() const;

// Operations

void DockControlBar(CControlBar* pBar, LPCRECT lpRect = NULL);

void ReDockControlBar(CControlBar* pBar, LPCRECT lpRect = NULL);

BOOL RemoveControlBar(CControlBar*, int nPosExclude = -1, int nAddPlaceHolder = 0);

void RemovePlaceHolder(CControlBar* pBar);

// Implementation

public:

virtual ~CDockBar();
