Get file name, line number and function name in QML Javascript from C++. How?

[bogong]

Hello!
I've got clear how to get file name, line number and function name in QML via Javascript function. The question is how to do the same but FROM C++, I need to get JavaScript file name, line number and function name in QML WITHOUT using JS directly. Just C++ code. Something like this:

C++ header

...
public slots:
	void mGetStack(void);
...

C++

void SomeClass::mGetStack(void) {
	... (some C++)
}

QML

onCompleted: {
	SomeClass.mGetStack()
}

What should be instead of "some C++"?
