加载状态栏

1.定义结构体：

static UINT BASED_CODE indicators[] =
{
    
    ID_SEPARATOR,           // status line Indicator
    ID_INDICATOR_POS,        //  Cursor Position Indicator
    ID_INDICATOR_OBJSIZE,    //  Cursor Position Indicator
    ID_INDICATOR_CAPS,        // Caps Lock Indicator
    ID_INDICATOR_NUM,        // Num Lock Indicator 
    ID_INDICATOR_SCRL,        // Scroll Lock Indicator
    ID_INDICATOR_CLOCK,        // Clock Indicator
    ID_INDICATOR_PAPER_SIZE,//page size
};

2.加载指示器

CStatusBar  m_wndStatusBar;
m_wndStatusBar.Create(this, WS_CHILD | WS_VISIBLE | CBRS_BOTTOM | CBRS_TOOLTIPS);
m_wndStatusBar.SetIndicators(indicators,sizeof(indicators)/sizeof(UINT));

3.添加相关文本

CRect RectTemp;    
GetClientRect(RectTemp);
int nLength;
nLength=0;
nLength=abs(RectTemp.right-RectTemp.left);
for(int k=0; k<=7; k++)
{
    UINT nID,nStyle;
    int nWidth;
    m_wndStatusBar.GetPaneInfo(k, nID, nStyle, nWidth);
    m_wndStatusBar.SetPaneInfo(k, nID, nStyle, nLength/8);
    m_wndStatusBar.SetPaneText(k,"Test");
}
RepositionBars(AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0);
m_wndStatusBar.ShowWindow(SW_SHOW);

单文档和多文档程序默认加载状态栏

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    if (CMDIFrameWnd::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("未能创建工具栏
");
        return -1;      // 未能创建
    }

    if (!m_wndStatusBar.Create(this) ||
        !m_wndStatusBar.SetIndicators(indicators,
          sizeof(indicators)/sizeof(UINT)))
    {
        TRACE0("未能创建状态栏
");
        return -1;      // 未能创建
    }

    // TODO: 如果不需要工具栏可停靠，则删除这三行
    m_wndToolBar.EnableDocking(CBRS_ALIGN_ANY);
    EnableDocking(CBRS_ALIGN_ANY);
    DockControlBar(&m_wndToolBar);

    return 0;
}

修改

void CDrawView::OnMouseMove(UINT nFlags, CPoint point)
{
    CString CursorPos;
    CString tmpstr = "X= -XXX   Y= -YYY";
    CPoint curPoint(point);
    ClientToDoc(curPoint);
    CursorPos.Format("x= %-4d   y= %-4d", curPoint.x, curPoint.y);
    CStatusBar *pStatusBar = (CStatusBar *)((CMainFrame *)(AfxGetApp()->m_pMainWnd))->GetDescendantWindow(AFX_IDW_STATUS_BAR);

    if (pStatusBar == NULL)
        return;

    UINT nIDPos;
    UINT nStylePos;
    int nWidth;

    CClientDC dc(pStatusBar);
    CFont* pOldFont = dc.SelectObject(pStatusBar->GetFont());
    CSize szExtent  = dc.GetTextExtent(tmpstr);
    dc.SelectObject(pOldFont);
    int nIndexPos = pStatusBar->CommandToIndex(ID_INDICATOR_POS);

    pStatusBar->GetPaneInfo(nIndexPos, nIDPos, nStylePos, nWidth);
    pStatusBar->SetPaneInfo(nIndexPos, nIDPos, nStylePos, szExtent.cx);
    pStatusBar->SetPaneText(nIndexPos,CursorPos);
}
