Detailed DescriptionThe QLibraryInfo class provides information about the Qt library. Many pieces of information are established when Qt is configured. Installation paths, license information, and even a unique build key. This class provides an abstraction for accessing this information.
You can also use a qt.conf file to override the hard-coded paths that are compiled into the Qt library. For more information, see the Using qt.conf documentation. See also QSysInfo and Using qt.conf. Member Type Documentation
