[Doxygen-develop] Adding file name to caller graph nodes

[Jan E. <jan...@we...>]

Hi,

I'm mostly interested in call- and caller-graphs generated by doxygen. I
would like to add the filename of a function (i.e. where it is defined)
to its node in the graph.
Is there an easy way of doing this?
If not, where in the source code should I look to find my way?

Thanks for any efforts
Jan
