有没有一种方法可以更改MFC SDI应用程序的标题字体？

Question

I am trying to increase the font size for the title on the MainFrame. So far, I have tried several approaches without a good result. Any suggestions are welcome.

A. Approach 1

    void CMainFrame::OnPaint()
{
CPaintDC dc(this); // device context for painting
    LOGFONT lF;
    lF.lfHeight = 10;
    lF.lfWidth = 0;
    lF.lfWeight = FW_NORMAL;
    lF.lfItalic = FALSE; //TRUE;
    lF.lfUnderline = FALSE; //TRUE;
    lF.lfStrikeOut = FALSE; //TRUE;
    lF.lfEscapement = 0;
    lF.lfOrientation = 0;
    _tcscpy_s(lF.lfFaceName, _T("Verdana"));

    CFont m_font;
    m_font.CreateFontIndirect(&lF);
    SetFont(&m_font);
       }

It doesn't change a thing.

B. Approach 2

     void CMainFrame::OnPaint()
     {
     CPaintDC dc(this); // device context for painting
    LOGFONT lF;
    lF.lfHeight = 10;
    lF.lfWidth = 0;
    lF.lfWeight = FW_NORMAL;
    lF.lfItalic = FALSE; //TRUE;
    lF.lfUnderline = FALSE; //TRUE;
    lF.lfStrikeOut = FALSE; //TRUE;
    lF.lfEscapement = 0;
    lF.lfOrientation = 0;
    _tcscpy_s(lF.lfFaceName, _T("Verdana"));

    CFont m_font;
    m_font.CreateFontIndirect(&lF);
    BOOL fRedraw = TRUE;
    SendMessageToDescendants(WM_SETFONT, (WPARAM)m_font.m_hObject);
      }

This approach deletes all my ribbon menus and creates a lot of exceptions.

Answer 1

The title bar is actually drawn and handled by the OS, program doesn't have a control over it. There is an OS wide setting to change it. Many applications use their own caption so that they can play around the styles of it.

You may want to look at this: http://msdn.microsoft.com/en-us/library/windows/desktop/bb688195(v=vs.85).aspx

However, as Mark Ransom suggested it is not easy.
