How to fix Qt 4 fonts on Mac OS X 10.9

[AndyBrice]

Mac OS X 10.9 was released yesterday. When I ran my Qt 4 app on 10.9, the text alignment in the controls was broken. Here is the fix:

#ifdef Q_OS_MACX
    if ( QSysInfo::MacintoshVersion > QSysInfo::MV_10_8 )
    {
        // fix Mac OS X 10.9 (mavericks) font issue
        // https://bugreports.qt-project.org/browse/QTBUG-32789
        QFont::insertSubstitution(".Lucida Grande UI", "Lucida Grande");
    }
#endif
 
    QApplication a( argc, argv );

#ifdef Q_OS_MACX
    if ( QSysInfo::MacintoshVersion > QSysInfo::MV_10_8 )
    {
        // fix Mac OS X 10.9 (mavericks) font issue
        // https://bugreports.qt-project.org/browse/QTBUG-32789
        QFont::insertSubstitution(".Lucida Grande UI", "Lucida Grande");
    }
#endif

    QApplication a( argc, argv );
