 Topic: How to disable font smoothingPosted: 02 August 2016 at 3:15am |

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; } |
