no spellchecking possible in header files

[bam80]

Sorry if it's naive issue, it's just first thing I faced when I managed to run the plugin.
I didn't install any dictionaries etc., but spellchecking works out of the box for .cpp files but not for .h files. Odd.
Sorry if I'm missing something obvious again.

For some reason, "Check external files" tick must be set to have spellchecking in headers.
This is odd as headers are part of the project, for sure.

For the context, the project is https://invent.kde.org/system/dolphin
