Now that we know how to use pointers to member functions, we can create commands that can take an object and a specific member function to call. Just like before, we will use a simple example. The example class isn't designed to do anything interesting, it is just used to demonstrate the concepts:
class SomeObject { public: SomeObject(int x):m_x(x){} void Display(void) { std::cout << "x is " << m_x << std::endl; } void Change(void) { m_x += m_x; } private: int m_x; };
Here is a simple class called SomeObject. It has a constructor that takes an int parameter and uses it to set the private member variable m_x. It also has two functions: one that will print the value to the screen and one that changes the ...
