Ambiguous members in multiple inheritance

I am trying to create a new class in my program which is being extended from two inbuilt classes in a framework.

class Node{
    setPosition();
    draw();
};

class Rectangle{
    setPosition();
    draw();
};

class CustomShape : public Node, public Rectangle{

};

In main program, if I try to write something like CustomShape a and 

a.setPosition();
a.draw();

I get compile time errors with ambiguous calls. How can I resolve this?

Add explicit qualifications:

a.Node::setPosition();
a.Rectangle::setPosition();

a.Node::draw();
a.Rectangle::draw();

Alternatively you can insert a cast:

static_cast<Node&>(a).setPosition();

But that's less attractive.
