Sample:
// header
class AAA {
public:
void Func();
};
// cpp file
void AAA::Func() {
std::string a;
int b;
NewFunc( a, b );
}
When I hover over "NewFunc", then from "down arrow menu" I can call "Add similar member", which will try add new member with signature "void NewFunc( std::string a, int b )" in class "AAA".
