在状态栏中显示鼠标的位置

 具体的实现见资源中心的CAD.rar

方法一：

(1)在String   Table中添加New   String，在此定义为IDS_MOUSE_POINT，将其Caption设为0000,0000  
  (2)在MainFrm.cpp中indicators声明处添加IDS_MOUSE_POINT,代码如下：    
  　　…    
  　　static   UINT   indicators[]   =    
  　　{    
  　　ID_SEPARATOR,      
  　　IDS_MOUSE_POINT,    
  　　ID_INDICATOR_CAPS,    
  　　ID_INDICATOR_NUM,    
  　　ID_INDICATOR_SCRL,    
  　　};    
  (3)在view里添加OnMouseMove函数及代码如下：  
  void   CEOView::OnMouseMove(UINT   nFlags,   CPoint   point)    
  {  
  //   TODO:   Add   your   message   handler   code   here   and/or   call   default  
  CMainFrame*   pFrame   =   (CMainFrame*)   AfxGetMainWnd();  
  CStatusBar*   pStatusBar   =   (CStatusBar*)   pFrame->GetDescendantWindow(AFX_IDW_STATUS_BAR);  
  CString   strMousePoint;  
  strMousePoint.Format("%4d,%4d",   point.x,   point.y);  
  pStatusBar->SetPaneText(pStatusBar->CommandToIndex(IDS_MOUSE_POINT),   strMousePoint);  
   
  CView::OnMouseMove(nFlags,   point);  

方法2

1、view resource symbol 打开对话框

2、new 打开new symbol

3、在name的标识符中IDC_STATUSBAR  VALUE 取默认值

4、在MainFrm.cpp中indicators声明处添加IDS_MOUSE_POINT,代码如下：    
  　　…    
  　　static   UINT   indicators[]   =    
  　　{    
  　　ID_SEPARATOR,      
  　　ID_SEPARATOR,

      ID_SEPARATOR,    
  　　ID_INDICATOR_CAPS,    
  　　ID_INDICATOR_NUM,    
  　　ID_INDICATOR_SCRL,    
  　　};    

5、 设置状态条信息的宽度CMainFrame::OnCreate

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("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
 }
    m_wndStatusBar.SetPaneInfo(1,IDC_STATUSBAR,SBPS_POPOUT,70);
    m_wndStatusBar.SetPaneInfo(2,IDC_STATUSBAR,SBPS_POPOUT,70);

 // TODO: Delete these three lines if you don't want the toolbar to
 //  be dockable

 

6 添加处理函数

 

void CCADView::OnMouseMove(UINT nFlags, CPoint point)
{
 // TODO: Add your message handler code here and/or call default

 char PositionString[50];
 CMainFrame*MFrame=(CMainFrame*)AfxGetMainWnd(); //定义主框架指针
 sprintf (PositionString,"X:%d",point.x);
    MFrame->m_wndStatusBar.SetPaneText(1,PositionString);
    sprintf (PositionString,"Y:%d",point.y);
    MFrame->m_wndStatusBar.SetPaneText(2,PositionString);
