I just got this to work. YMMV

I don't suppose it has to be there, but I put my file, xyz.cpp, into my project's source directory. My project has a source subdir named src, as in ProjName/src.

The file will open in the editor and complain that it is empty. Close it WITHOUT SAVING.

Reopen the file. It now has its contents.
