无边框模式对话框,设置鼠标拖动

无边框模式对话框,设置鼠标拖动

1. 对话框中创建成员变量

long _icur;

2. 响应对话框类消息 WM_NCHITTEST

    ScreenToClient(&point);
    RECT rtWindow;
    GetClientRect(&rtWindow);
    long wndHeight = rtWindow.bottom - rtWindow.top;
    long wndWidth = rtWindow.right - rtWindow.left;
    _icur = 0;
    RECT rcW = {0,0,wndWidth,100};
    if(::PtInRect(&rcW,point))
    {  
        return HTCAPTION;  // 在拖动范围内
    }
    return CWnd::OnNcHitTest(point);

3. 响应对话框类消息 WM_SETCURSOR

    if(_icur==0)
    {
        ::SetCursor(AfxGetApp()->LoadStandardCursor(IDC_ARROW));
        return TRUE;
    }
    return CDialog::OnSetCursor(pWnd, nHitTest, message);
