Let's say that I have a class:

//-------------------------------

class Application {
public:
  virtual void quit();

protected:
  virtual bool main();
};

//-------------------------------

Then I create derived class:

//-------------------------------

class Client : public Application {
public:
  // Ctrl+Space here offers me an option to override the function

protected:
  // Ctrl+Space here DOES NOT offer me an option to override the function
};

//-------------------------------

Reproducible: Always
