I would like to control font smoothing / anti-aliasing of the text in the toolkit controls.

Preferred would be that the system setting for font smoothing (Advanced System Settings > Performance Settings > "Smooth edged of screen fonts") would be used so that standard controls like window menus and Toolkit controls use the same way to display font.

How can I control text anti aliasing?

Found it by digging through the code:

In my paint manager impl I get the current LOGFONT, set its lfQuality member and apply that font.

if(m_fontCaption.GetLogFont(&lf))

{

lf.lfQuality = NONANTIALIASED_QUALITY;

SetCaptionFont(lf);

SetTextFont(lf);

}

Would be nice if the draw helper class could use some global state and not IsClearTypeTextQualitySupported to control this:

BOOL CXTPDrawHelpers::GetIconLogFont(LOGFONT* pLogFont)

{

ASSERT(pLogFont);

if (!pLogFont)

return FALSE;

::ZeroMemory(pLogFont, sizeof(LOGFONT));

if (::SystemParametersInfo(SPI_GETICONTITLELOGFONT, sizeof(LOGFONT), pLogFont, 0))

{

if (XTPSystemVersion()->IsClearTypeTextQualitySupported())

pLogFont->lfQuality = CLEARTYPE_QUALITY;

pLogFont->lfCharSet = XTPResourceManager()->GetFontCharset();

return TRUE;

}

return FALSE;

}
