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;
}


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?

You have to create your own debugging helper, and plug it into QtCreator, you can use C++ / Python to implement your own debugging helper for your custom types.

Seems to work as expected in builds made from 'master' branch, but not in 2.2.1.
