Not sure how looking at Atom would help, but you should absolutely try 
it. It's Free Software, after all.

You have to find out what the type of the call target is, first.

In your example, it's rather easy: "QPushButton quit" is right on the 
previous line.

But what if we're at the end of a chain of calls, like

app->window->resolve_handler(bar).|

?

And resolve_handler is overloaded, and its return type is dependent on 
the type of its argument?

What if `bar' is declared as `auto' (see C++11)? Or `app' itself?

I'm fairly sure an experienced C++ tooling developer could add other 
complicated examples.
