How to Access MFC Status Bar from View class?

[Chris Tessmer]

When I create a new MFC app, I get this status bar object in my CMainFrame class called "m_wndStatusBar." Is there any way I can access this from my View or Doc class? It would help greatly to be able to display text in it based on what happens in either class...

Thanks a lot,

- Chris.

Hi,
Accroding as "Visual C++ 4.0 HOW-TO". p99
To show the caret postion of View to status bar

static UINT indicators[] =
{ ......
ID_INDICATOR_CARET,
};
//at the message map of CMyView
afx_msg void OnUpdateCaretPos(CCmdUI* pCmdUI);

void CMyView::OnUpdateCaretPos(CCmdUI* pCmdUI)
{
int nLine, nCol;
GetCaretPosition(nLine, nCol);//determine the position of caret.
CString str;

str.Format("Ln %d, Col %d", nLine, nCol);

pCmdUI->Enable(TRUE);
pCmdUI->SetText(str);
}

Hope for help.

your variable m_wndStatusBar is public, and you can access it from everywhere. So you may do:

BOOL CMyView::UpdateStatusBar(int iPosition, CString &strNewText)
{
CMainFrame *pFrame=(CMainFrame *)AfxGetApp()->m_pMainWnd;
return pFrame->m_wndStatusBar.SetPaneText(iPosition, strNewtext);
}

If you want to be "cleaner", you may define m_wndStatusBar as protected, and write an inline method GetStatusBar() in your method.

HTH.

If you just want to display text on the status bar, use:

CFrameWnd::SetMessageText( LPCTSTR lpszText );

as in:

dynamic_cast < CFrameWnd > (AfxGetMainWnd())->SetMessageText("Status message");
