Detailed Description

\inmodule QtCore

The QLibraryInfo class provides information about the Qt library.

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 \l {Using qt.conf} documentation.

Member Enumeration Documentation

◆ LibraryPath

enum QLibraryInfo::LibraryPath

\keyword library location

This enum type is used to query for a specific path:

\value PrefixPath The default prefix for all paths. \value DocumentationPath The path to documentation upon install. \value HeadersPath The path to all headers. \value LibrariesPath The path to installed libraries. \value LibraryExecutablesPath The path to installed executables required by libraries at runtime. \value BinariesPath The path to installed Qt binaries (tools and applications). \value PluginsPath The path to installed Qt plugins. \value QmlImportsPath The path to installed QML extensions to import. \value Qml2ImportsPath This value is deprecated. Use QmlImportsPath instead. \value ArchDataPath The path to general architecture-dependent Qt data. \value DataPath The path to general architecture-independent Qt data. \value TranslationsPath The path to translation information for Qt strings. \value ExamplesPath The path to examples upon install. \value TestsPath The path to installed Qt testcases. \value SettingsPath The path to Qt settings. Not applicable on Windows.

Definition at line 231 of file qlibraryinfo.cpp.

◆ isDebugBuild()

bool QLibraryInfo::isDebugBuild ( )
staticnodiscardnoexcept
Since
5.0 Returns true if this build of Qt was built with debugging enabled, or false if it was built in release mode.

Definition at line 242 of file qlibraryinfo.cpp.

◆ isSharedBuild()

bool QLibraryInfo::isSharedBuild ( )
staticnodiscardnoexcept
Since
6.5 Returns true if this is a shared (dynamic) build of Qt.
