KService allows to query information about installed applications and their associated file types.
The two relevant classes are:
- KService: This models an installed application and allows to query various properties about it
- KApplicationTrader: This is used to list available applications as well as applications associated with a given file type
KSycoca caches the information about available applications and file associations for faster access.
If you are using CMake, you need to have
find_package(KF6Service)
(or similar) in your CMakeLists.txt file, and you need to link to KF6::Service.
