KService
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
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 Service)
target_link_libraries(mytarget PRIVATE KF6::Service)
For more details, see the Build with CMake overview.
