It would be nice to able to modify the increase the tab margin to avoid some tab label issues.

If the fontRegular is switched to 12 point some small tab labels aren't drawn correctly, e.g. 'Cab', it appears to be a problem with capital C. Once you get to 'Cable' or 'Code' it sorts itself out.

Details (expand)

Visual Studio 2010

Compatibility

Create a tabbed MFC app, call SetMenuFont to change the font size to the default font height (i.e. not -1). Save a doc as something like 'Ca' and switch to another tab.

CWindowDC dc(NULL);

NONCLIENTMETRICS info = {0};
info.cbSize = sizeof( NONCLIENTMETRICS );
if ( ::SystemParametersInfo(SPI_GETNONCLIENTMETRICS, info.cbSize, &info, 0) )
{
    LOGFONT lf;
    memset(&lf, 0, sizeof(LOGFONT));

    lf.lfCharSet = (BYTE) GetTextCharsetInfo(dc.GetSafeHdc(), NULL, 0);

    lf.lfHeight = info.lfMenuFont.lfHeight;
    lf.lfWeight = info.lfMenuFont.lfWeight;
    lf.lfItalic = info.lfMenuFont.lfItalic;

    //------------------
    // Adjust font size:
    //------------------
    int nFontHeight = lf.lfHeight < 0 ? -lf.lfHeight : lf.lfHeight;
    if (nFontHeight < 11)
        nFontHeight = 11;

    lf.lfHeight = (lf.lfHeight < 0) ? -nFontHeight : nFontHeight;

    lstrcpy(lf.lfFaceName, info.lfMenuFont.lfFaceName);

    afxGlobalData.SetMenuFont( &lf, TRUE );
}

The tab label is drawn as 'C...'.

DrawText is adding the ellipses because it can't draw in the given rect.

The tab label should be 'Ca'

File attached. Steps (on Win 7 - x86)

1. Build project
2. Run EXE
3. Save first doc as: Cab
4. Create new doc

You should see first tab has been shortened to 'C...'

Note: It doesn't happen with all tab styles, this project has been set to STYLE_3D_VS2005.
