Doxygen does not show how the documented member functions (including the constructors) are called from other classes.?

Question

Doxygen does not show how the documented member functions (including the constructors) are called from other classes. ?

I set 'auto documentation' with the EXTRACT_ALL option. I set the CALL_GRAPH option to get the call references. Also I did have the graphviz/dot (output) options enabled.

Here is the log of my selections:

Answer 1

Change

SOURCE_BROWSER = NO 
INLINE_SOURCES = NO 
STRIP_CODE_COMMENTS = YES 
REFERENCED_BY_RELATION = NO 
REFERENCES_RELATION = NO 
REFERENCES_LINK_SOURCE = YES 
USE_HTAGS = NO 
VERBATIM_HEADERS = YES 

To

SOURCE_BROWSER = YES
INLINE_SOURCES = YES
STRIP_CODE_COMMENTS = YES 
REFERENCED_BY_RELATION = YES
REFERENCES_RELATION = YES
REFERENCES_LINK_SOURCE = YES 
USE_HTAGS = NO 
VERBATIM_HEADERS = YES

---

The main ones you really need to change though, are REFERENCED_BY_RELATION, and REFERENCES_RELATION.

Here is the documentation on those two options:

REFERENCED_BY_RELATION If the REFERENCED_BY_RELATION tag is set to YES then for each documented function all documented functions referencing it will be listed.

REFERENCES_RELATION If the REFERENCES_RELATION tag is set to YES then for each documented function all documented entities called/used by that function will be listed.
