We introduce QPlatformFontDatabase::isPrivateFontFamily() to allow testing for private, system UI font families. Both QFontComboBox and QFontDialog need to filter out those private font families which, by definition, should be hidden from the end user. (The textedit example had to be updated to fix the issue where the default font would be private. In 5.4, we will be adding an equivalent, public API in QFontDatabase, and a better solution for the textedit example and QTexEdit in general). In particular, on OS X and iOS, private fonts are used for the system UI font. Those have their font family name prefixed by a dot. QCoreTextFontDatabase knows about this, and makes sure those are tested positive as private font families. In order to have a cleaner layer separation, we moved the QPA theme font resolution from the platform theme classes into QCoreTextFontDatabase for both Cocoa and iOS QPA plugins. In both cases, we use CoreText's CTFontCreateUIFontForLanguage(), that nicely maps to the HITheme API we were using so far on Mac. That means one HITheme dependency less. We also cache the font descriptors we get for these font for each time QCTFD::populateFamilies() gets called. (While not common, this currently happens in auto-tests, like tst_QFontDatabase, and could happen in actual applications -- specially when adding and removing application fonts.)

Qt is supplied with a number of example applications that have been written to provide developers with examples of the Qt API in use, highlight good programming practice, and showcase features found in each of Qt's core technologies. Documentation for examples can be found in the Examples section of the Qt documentation.
