利用CRebar和CDialogBar编写可浮动的dialog类型的工具栏

这个crebar用起来参数真奇怪, 算了, 直接上代码吧:
先弄一个基于cdialog的类CMyDlgBar,将基类改为cdialogbar, 需要注意必须修改 constructor(没有参数), OnInitDialog(里面需要初始化)

class CMyDlgBar : public CDialogBar
{
    DECLARE_DYNAMIC(CMyDlgBar)

public:
    CMyDlgBar();   // standard constructor
    virtual ~CMyDlgBar();

// Dialog Data
    enum { IDD = IDD_DIALOG1 };

protected:
    virtual void DoDataExchange(CDataExchange* pDX);    // DDX/DDV support

    DECLARE_MESSAGE_MAP()
public:
    virtual BOOL Create(CWnd* pParentWnd, UINT nIDTemplate, UINT nStyle, UINT nID);
    int m_nData;
    afx_msg void OnBnClickedOk();
//    afx_msg void OnBnClickedButton1();
    afx_msg void OnBnClickedButton1();
    afx_msg LRESULT OnInitDialog(UINT wParam,LONG lParam);

    afx_msg void OnEnChangeEdit1();
};

// CMyDlgBar dialog

IMPLEMENT_DYNAMIC(CMyDlgBar, CDialogBar)

CMyDlgBar::CMyDlgBar()
    : CDialogBar()
    , m_nData(0)
{

}

CMyDlgBar::~CMyDlgBar()
{
}

void CMyDlgBar::DoDataExchange(CDataExchange* pDX)
{
    CDialogBar::DoDataExchange(pDX);
}


BEGIN_MESSAGE_MAP(CMyDlgBar, CDialogBar)
    ON_BN_CLICKED(IDOK, &CMyDlgBar::OnBnClickedOk)
//    ON_BN_CLICKED(IDC_BUTTON1, &CMyDlgBar::OnBnClickedButton1)
ON_BN_CLICKED(IDC_BUTTON1, &CMyDlgBar::OnBnClickedButton1)
ON_EN_CHANGE(IDC_EDIT1, &CMyDlgBar::OnEnChangeEdit1)
ON_MESSAGE(WM_INITDIALOG,OnInitDialog)
END_MESSAGE_MAP()

LRESULT CMyDlgBar::OnInitDialog(UINT wParam,LONG lParam)

{

    // TODO: Add extra initialization here

    BOOL bRet = HandleInitDialog(wParam,lParam);

    if (!UpdateData(FALSE))

    {

        TRACE("InitCDataStatus Failed！");

    }

    return TRUE; // return TRUE unless you set the focus to a control

    // EXCEPTION: OCX Property Pages should return FALSE

}

// CMyDlgBar message handlers

BOOL CMyDlgBar::Create(CWnd* pParentWnd, UINT nIDTemplate, UINT nStyle, UINT nID)
{
    // TODO: Add your specialized code here and/or call the base class

     CDialogBar::Create(pParentWnd, nIDTemplate, nStyle, nID);
     UpdateData(FALSE);
     return TRUE;
}

void CMyDlgBar::OnBnClickedOk()
{
    // TODO: Add your control notification handler code here
}

//void CMyDlgBar::OnBnClickedButton1()
//{
//    // TODO: Add your control notification handler code here
//}

void CMyDlgBar::OnBnClickedButton1()
{
    // TODO: Add your control notification handler code here
}


void CMyDlgBar::OnEnChangeEdit1()
{
    // TODO:  If this is a RICHEDIT control, the control will not
    // send this notification unless you override the CDialogBar::OnInitDialog()
    // function and call CRichEditCtrl().SetEventMask()
    // with the ENM_CHANGE flag ORed into the mask.
    MessageBox(L"Changed");
    // TODO:  Add your control notification handler code here
}


在cmainframe里面定义两个变量
CMyDlgBar m_barAttrib;
    CReBar      m_wndReBar;

必须实现oncreate和oncmdmsg

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    if (CFrameWnd::OnCreate(lpCreateStruct) == -1)
        return -1;
    
    if (!m_wndToolBar.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP
        | CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) ||
        !m_wndToolBar.LoadToolBar(IDR_MAINFRAME))
    {
        TRACE0("Failed to create toolbar\n");
        return -1;      // fail to create
    }

    if (!m_wndStatusBar.Create(this) ||
        !m_wndStatusBar.SetIndicators(indicators,
          sizeof(indicators)/sizeof(UINT)))
    {
        TRACE0("Failed to create status bar\n");
        return -1;      // fail to create
    }

    // TODO: Delete these three lines if you don't want the toolbar to be dockable
    if (!m_barAttrib.Create(this,m_barAttrib.IDD, CBRS_ALIGN_RIGHT|CBRS_GRIPPER, m_barAttrib.IDD))
    {
        TRACE0("Failed to create dialogbar\n");
        return -1;
    }
    m_barAttrib.SetWindowText(L"部件属性");
    /**//*XXX是一个资源id手工直接在资源的.h文件中添加一条，不会，这里就不教了。
        工具条的显示和隐藏代码如下，自己慢慢理解吧：*/
    //    ShowControlBar(&m_barAttrib, (m_barAttrib.GetStyle() & WS_VISIBLE) == 0, FALSE);

    //m_wndReBar.Create(this);
    m_wndReBar.Create(this,   RBS_AUTOSIZE   |   RBS_BANDBORDERS,
        /**//*WS_CHILD   |   WS_VISIBLE   |  WS_CLIPSIBLINGS   |   WS_CLIPCHILDREN   | */  CBRS_RIGHT) ;
    m_wndReBar.AddBar(&m_barAttrib,NULL,NULL, RBBS_GRIPPERALWAYS|RBBS_FIXEDBMP);
    
    //m_wndReBar.AddBar(&m_wndToolBar,NULL,NULL, RBBS_GRIPPERALWAYS|RBBS_FIXEDBMP);
    m_barAttrib.EnableDocking(CBRS_ALIGN_ANY);
    
    m_wndToolBar.EnableDocking(CBRS_ALIGN_ANY);
    EnableDocking(CBRS_ALIGN_ANY);
    DockControlBar(&m_barAttrib);
    DockControlBar(&m_wndToolBar);
    
    
    return 0;
}
BOOL CMainFrame::OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo)
{
    // TODO: Add your specialized code here and/or call the base class

    if(m_barAttrib.OnCmdMsg(nID, nCode, pExtra, pHandlerInfo))
        return TRUE;
    return CFrameWnd::OnCmdMsg(nID, nCode, pExtra, pHandlerInfo);
}
