QLibraryInfo

The QLibraryInfo class provides information about the Qt library. More…

Synopsis

Static functions

• def build ()

• def buildDate ()

• def isDebugBuild ()

• def licensedProducts ()

• def licensee ()

• def location (arg__1)

• def platformPluginArguments (platformName)

• def version ()

Detailed Description

Many pieces of information are established when Qt is configured and built. This class provides an abstraction for accessing that information. By using the static functions of this class, an application can obtain information about the instance of the Qt library which the application is using at run-time.

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.
