策略为王源代码分析-状态条

在MFC的的单文档应用中，在建好应用程序之后，在CMainFrame类中定义状态栏对象CStatusBar m_wndStatusBar;

step 1.定义状态栏对象CStatusBar m_wndStatusBar;

G:\stock\TskingVS2019\src\Client\StkUI\MainFrm.h

class CMainFrame : public CTskMainFrame
{
...

CStatusBar m_wndStatusBar;
....

step 2： CMainFrame::OnCreate()函数中进行状态栏的创建

2.1 向indicators数组里面添加元素

G:\stock\TskingVS2019\src\Client\StkUI\MainFrm.cpp

/////////////////////////////////////////////////////////////////////////////
// CMainFrame

// toolbar buttons - IDs are command buttons
static UINT indicators[] =
{
	//ID_SEPARATOR,           // status line indicator
	//ID_SEPARATOR,           // stock indicator, and progress indicator
	//ID_SEPARATOR,           // stock indicator
	//ID_SEPARATOR,           // time indicator
	//ID_INDICATOR_CAPS,
	ID_SEPARATOR,          // 状态行指示器
 ID_INDICATOR_CAPS,
 ID_INDICATOR_NUM,
 ID_INDICATOR_SCRL
};

2.2 在int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)函数中进行状态栏的创建，代码如下：

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
	if (CTskMainFrame::OnCreate(lpCreateStruct) == -1)
		return -1;

	// ******************************************
	// 自定义状态栏
	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
	}
...
}

运行程序后，状态栏的右下角默认有三个Pane，其定义在MainFrm.cpp文件中的indicators数组里面.

第二部分 修改面板属性

	// Set Status Bar Styles
	UINT nID, nStyle;
	int cxWidth;
	m_wndStatusBar.GetPaneInfo(1, nID, nStyle, cxWidth);
	m_wndStatusBar.SetPaneInfo(1, nID, nStyle, 200);
	m_wndStatusBar.GetPaneInfo(2, nID, nStyle, cxWidth);
	m_wndStatusBar.SetPaneInfo(2, nID, nStyle, 200);
	m_wndStatusBar.GetPaneInfo(3, nID, nStyle, cxWidth);
	m_wndStatusBar.SetPaneInfo(3, nID, nStyle, 50);
	m_wndStatusBar.GetStatusBarCtrl().SetMinHeight(20);

	HICON icon = AfxGetApp()->LoadIcon(IDI_INDICATOR);
	m_wndStatusBar.GetStatusBarCtrl().SetIcon(0, icon);

	//m_wndStatusBar.GetStatusBarCtrl().SetBkColor(RGB(180, 180, 180));

第三部分 用定时器更新状态条信息

/////////////////////////////////////////////////////////////////////////////
// CMainFrame message handlers

void CMainFrame::OnTimer(UINT nIDEvent)
{
	if (TIMER_TIME == nIDEvent)
	{
		CSPTime	time = CSPTime::GetCurrentTime();
		CString	string = (LPCTSTR)AfxGetTimeString(time.GetTime(), "%H:%M:%S", FALSE);
		m_wndStatusBar.SetPaneText(3, string);
	}
	else if (TIMER_STOCKINDEXREFRESH == nIDEvent)
	{
		CString strSHTipFmt, strSZTipFmt;
		strSHTipFmt.LoadString(IDS_MAINFRAME_SHINDEXTIP);
		strSZTipFmt.LoadString(IDS_MAINFRAME_SZINDEXTIP);

		double dDevided = 100000000;
#ifdef CLKLAN_ENGLISH_US
		dDevided = 1000000000;
#endif

		CString	string;
		double	dDiff = 0;
		CStockInfo	info;
		COLORREF	clrRise = AfxGetProfile().GetColor(CColorClass::clrRise);
		COLORREF	clrFall = AfxGetProfile().GetColor(CColorClass::clrFall);

		//取上证指数，这里为000001 ，取到了股票代码，有问题 by freeman 2019/06/08
		if (AfxGetStockContainer().GetStockInfo(STKLIB_CODE_SZZS, &info))
		{
			info.GetDiff(&dDiff, info.m_datetech, 1);
			string.Format(strSHTipFmt, info.m_fClose, dDiff, info.m_fAmount / dDevided);
			// m_wndStatusBar.SetPaneColor(dDiff > 0 ? clrRise : clrFall);
			m_wndStatusBar.SetPaneText(1, string);
		}
		//取深证成指 by freeman
		if (AfxGetStockContainer().GetStockInfo(STKLIB_CODE_SZNCZ, &info))
		{
			info.GetDiff(&dDiff, info.m_datetech, 1);
			string.Format(strSZTipFmt, info.m_fClose, dDiff, info.m_fAmount / dDevided);
			// m_wndStatusBar.SetPaneColor(dDiff > 0 ? clrRise : clrFall);
			m_wndStatusBar.SetPaneText(2, string);
		}
