상태바 (Status Bar)

선언

// CMainFrame
protected:
	CStatusBar           m_wndStatusBar;   // vs 6
	CMFCStatusBar     m_wndStatusBar;

indicator(상태바 아이템)

static UINT indicators[] =
{
	ID_SEPARATOR,           // status line indicator
	ID_INDICATOR_CAPS,
	ID_INDICATOR_NUM,
	ID_INDICATOR_SCRL,
};

생성

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

메소드

• void SetPaneInfo(int nIndex, UINT nID, UINT nStyle, int cxWidth);
  

  <indicator Styles>

  SBPS_NOBORDERS	No 3-D border around the pane.
  SBPS_POPOUT	Reverse border so that text "pops out."
  SBPS_DISABLED	Do not draw text.
  SBPS_STRETCH	Stretch pane to fill unused space. Only one pane per status bar can have this style.
  SBPS_NORMAL	No stretch, borders, or pop-out.

• BOOL SetPaneText(int nIndex, LPCTSTR lpszNewText, BOOL bUpdate = TRUE);
• void SetPaneStyle(int nIndex, UINT nStyle);
• int CommandToIndex(UINT nIDFind) const;
  Gets the indicator index for a given ID.

예제

1. String Table에 String을 하나 만듦(ID_PARSE_TIME)
2. indicator에 등록(CMainFrame)
   

   static UINT indicators[] =
   {
   	ID_SEPARATOR,           // status line indicator
   	ID_PARSE_TIME,	// parsing time
   	ID_INDICATOR_CAPS,
   	ID_INDICATOR_NUM,
   	ID_INDICATOR_SCRL,
   };
   

3. 텍스트 크기가 잘릴 것을 대비해 OnCreate()에서 길이를 늘려줌.
   

   m_wndStatusBar.SetPaneInfo(1, ID_PARSE_TIME, SBPS_NORMAL, 50);
   

4. m_wndStatusBar가 protected로 선언했기 때문에 Statusbar 텍스트를 변경하는 함수를 만듦. public으로 변수를 만들어서 함수를 만들지 않고 직접 변수에 접근하여 컨트롤 할 수 있음
   

   BOOL CMainFrame::SetPaneText(int nIndex, LPCTSTR lpszNewText)
   {
   	return m_wndStatusBar.SetPaneText(nIndex, lpszNewText);
   }
   

5. 텍스트 변환
   

   CMainFrame* pMainFrame = (CMainFrame*) ::AfxGetMainWnd();
   // CMFCStatusBar* pStatus = &pMainFrame->m_wndStatusBar;
   
   CString tmp;
   float t = m_htmlFile.get_parse_time();
   tmp.Format(L"%5.3f sec", t);
   
   pMainFrame->SetPaneText(1, tmp);
   // pStatus->SetPaneText(1, tmp);
   

6. 활성 상태로 변환(Message map 연결)
   

   • afx_msg void OnUpdateParseTime(CCmdUI* pCmdUI);
     

   • ON_UPDATE_COMMAND_UI(ID_PARSE_TIME, OnUpdateParseTime)
     

   • void CMainFrame::OnUpdateParseTime(CCmdUI* pCmdUI)
     {
     	pCmdUI->Enable();
     }
