KConfig
Persistent platform-independent application settings.
KConfig provides an advanced configuration system. It is made of two parts: KConfigCore and KConfigGui.
KConfigCore provides access to the configuration files themselves. It features:
- Code generation: describe your configuration in an XML file, and use kconfig_compiler to generate classes that read and write configuration entries.
- Cascading configuration files (global settings overridden by local settings).
- Optional shell expansion support.
- The ability to lock down configuration options.
KConfigGui provides a way to hook widgets to the configuration so that they are automatically initialized from the configuration and automatically propagate their changes to their respective configuration files.
Using the Module
Using a KDE module's C++ API requires linking against the module library. The preferred way of consuming the library is through CMake.
Building with CMake
Use the find_package() command to locate the needed module component in the KF6 package:
find_package(KF6 REQUIRED COMPONENTS Config)
target_link_libraries(mytarget PRIVATE KF6::ConfigCore)
For more details, see the Build with CMake overview.
