Detailed Description

The PySide.QtCore.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.

Function Return value
PySide.QtCore.QLibraryInfo.buildKey() A string that identifies the Qt version and the configuration. This key is used to ensure that plugins link against the same version of Qt as the application.
PySide.QtCore.QLibraryInfo.location() The path to a certain Qt component (e.g., documentation, header files).
PySide.QtCore.QLibraryInfo.licensee() , PySide.QtCore.QLibraryInfo.licensedProducts() Licensing 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.
