Issues with adding a CComboBox to a CMFCStatusBar pane

I have this simple code to create a CComboBox and display it on a pane in a CMFCStatusBar:

CRect rcPane;
m_StatusBar.GetItemRect(panePageBreaks, &rcPane);
CFont *pFont = m_StatusBar.GetFont();

m_myCombo.Create(WS_CHILD | WS_VISIBLE | WS_VSCROLL | CBS_DROPDOWNLIST, rcPane, &m_StatusBar, 2500);
m_myCombo.SetFont(pFont);
m_myCombo.AddString(_T("Page Breaks: None"));
m_myCombo.AddString(_T("Page Breaks: 1 Week"));
m_myCombo.AddString(_T("Page Breaks: 2 Weeks"));
m_myCombo.AddString(_T("Page Breaks: 3 Weeks"));
m_myCombo.AddString(_T("Page Breaks: 4 Weeks"));

Can I make the status bar big enough to encompass this combo? At the moment it is a pixel or two too short in height:

StatusBar

Update

If I use:

rcPane.InflateRect(1, 2, 0, 2);

It seems to be better. But i don't want to fudge it. Another users PC might be different. I want this combo to be exact over the specific pane.

Update

I am kind of annoyed now. I found a similar question here which implies doing two things:

  1. Changing the font height.
  2. Using SetItemHeight.

So I employed both of these and I found that I would need a font height of -6 for the control to have the right height:

CRect rcPane;
m_StatusBar.GetItemRect(panePageBreaks, &rcPane);
CFont *pFont = m_StatusBar.GetFont();
LOGFONT sLF;
pFont->GetLogFont(&sLF);
sLF.lfHeight = -6;
pFont->CreateFontIndirect(&sLF);

m_myCombo.Create(WS_CHILD | WS_VISIBLE | WS_VSCROLL | CBS_DROPDOWNLIST, rcPane, &m_StatusBar, 2500);
m_myCombo.SetItemHeight(-1, rcPane.Height());
m_myCombo.SetFont(pFont);
m_myCombo.AddString(_T("Page Breaks: None"));
m_myCombo.AddString(_T("Page Breaks: 1 Week"));
m_myCombo.AddString(_T("Page Breaks: 2 Weeks"));
m_myCombo.AddString(_T("Page Breaks: 3 Weeks"));
m_myCombo.AddString(_T("Page Breaks: 4 Weeks"));

Status Bar with Combo

You see, you can set the height of the edit control, but if your font height is larger it will make the edit control larger. So I can't go over -6. And the status bar text is -12. So this is not an option.

All I was trying to do was provide an easy way for the user to change this setting via the status bar as well as via menu navigation. But it looks like I can't do it.

If anything the CMFCStatusBar height needs to be a tad taller than the default CComboBox edit control height.

This code show how to increase the height of the statusbar. In this way you can use the stardard controls in your statubar without any modification.

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

    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));

    m_wndStatusBar.GetStatusBarCtrl().SetMinHeight(70); // or, whatever you need

    return 0;
}
