So i understand that we can not reach them from derived class.

It is more like copying every member of the base class into the child class, but putting it all under the private keyword. The child class can see (that is call) the base class' methods, but any outsiders would only be able to call the child class' public methods.

Not really. OP got it right, just used protected in his sample.

lass Wilma {
protected:
void fredCallsWilma()
{
std::cout << "Wilma::fredCallsWilma()\n";
wilmaCallsFred();
}
virtual void wilmaCallsFred() = 0; // A pure virtual function
};

class Fred : private Wilma {
public:
void barney()
{
std::cout << "Fred::barney()\n";
Wilma::fredCallsWilma(); //this can reach private function
}
protected:
virtual void wilmaCallsFred()

std::cout << "Fred::wilmaCallsFred()\n";

From the outsider's point of view it is correct, but the child class cannot access non-public members of base, and if you copy every member of the base to child's private section, all of them would be accessible from the child.

Open file dialog box is not designed for such functionality, it is common dialog box, though it is not impossible.
