Is it possible to make ggtags able to generate calling graph for c++ functions ?

I think it'll be great if the ggtags could support this feature, it will massively improve develop efficiency.

[beacoder]

for example:
if I could to see the calling graph for funcA,
I just place my cursor on funcA, and execute something like "ggtags-find-calling-graph".
and ggtags pops up with a view like this, like the tree structure.

funcA
|
|----funcB
| |
| |----funcB1
|
|----funcD
| |
| |----funcD1

And since the ggtags-find-reference is able to find the reference of functions, so it should be able to recursively find the upper nodes (funcB, funcD).
So it seems ggtags don't need support from GNU Global to support this feature, right ?

Yes. You need to request this feature from gnu global.
