Which Doxygen option can completely disable sorting members by type (Private / Public / Method / Variable), and output members purely based on the order in which they were declared?
This is impossible via the config options. The best you can do is:
SORT_MEMBER_DOCS = NO
which disables alphabetical sorting of members.
