Subclassing

[voorugonda prashanth]

can u please give me a example????

[toxcct]

class BaseClass {
int m_iSize;

public:
int getSize() { return m_iSize; }
void setSize(int i) { m_iSize = i; }
};

class ChildClass : public BaseClass {
double m_dPrice;

public:
double getPrice() { return m_dPrice; }
void getPrice(double d) { m_dPrice = d; }
};

then, you use it like any object which contains all...

ChildClass cc;
cc.setSize(4);

Is always tought that subclassing was to change the behaviour of a class in a framework without changing the framework. I guess i'm wrong but what is then the correct term for this kind of pattern. Let me explain by a simple example. You create your own windowproc which is then used to overwrite the normal winproc. By using your own windowproc you can change the behaviour of the subclassed window. codito ergo sum
