How to watch data of actual type in debugger?

[kamre]

Very simple example with classes hierarchy:

class Object {
public:
  Object(int id_) : id(id_) {}
  virtual ~Object() {}
 
private:
  int id;
};
 
class Point: public Object {
public:
  Point(double x_, double y_, int id_)
    : Object(id_), x(x_), y(y_) {}
 
private:
  double x, y;
};
 
class Circle: public Point {
public:
  Circle(double x_, double y_, double r_, int id_)
    : Point(x_, y_, id_), r(r_) {}
 
private:
  double r;
};
 
int test(Object *obj)
{
   return 0; // <== break point here
}
 
int main()
{
  test(new Circle(1.5, -2.5, 3.0, 15));
  return 0;
}

class Object {
public:
  Object(int id_) : id(id_) {}
  virtual ~Object() {}

private:
  int id;
};

class Point: public Object {
public:
  Point(double x_, double y_, int id_)
    : Object(id_), x(x_), y(y_) {}

private:
  double x, y;
};

class Circle: public Point {
public:
  Circle(double x_, double y_, double r_, int id_)
    : Point(x_, y_, id_), r(r_) {}

private:
  double r;
};

int test(Object *obj)
{
   return 0; // <== break point here
}

int main()
{
  test(new Circle(1.5, -2.5, 3.0, 15));
  return 0;
}

When I set breakpoint in QtCreator and try to watch "obj" in debugger it doesn't show the actual (runtime instead of static) type and corresponding data. This is how it looks like:


And I would like to see something like in MSVC debugger:


How can I configure QtCreator to show the actual runtime data?
