I have a set of callback classes that I use for handling callbacks with variable numbers of parameters. Right now I have about 6 different instances of it to handle differing numbers of arguments. Is there a way to make one instance than can handle a variable number of arguments?? Ultimately I would love to have each parameter be a POD type or a class pointer, or a struct pointer. Any ideas?
template <class T>
class kGUICallBackPtr
{
public:
kGUICallBackPtr() {m_obj=0;m_func=0;}
void Set(void *o,void (*f)(void *,T *));
inline void Call(T *i) {if(m_func) m_func(m_obj,i);}
inline bool IsValid(void) {return (m_func!=0);}
private:
void *m_obj;
void (*m_func)(void *,T *);
};
template <class T,class U>
class kGUICallBackPtrPtr
{
public:
kGUICallBackPtrPtr() {m_obj=0;m_func=0;}
void Set(void *o,void (*f)(void *,T *,U *));
inline void Call(T *i, U *j) {if(m_func) m_func(m_obj,i,j);}
inline bool IsValid(void) {return (m_func!=0);}
private:
void *m_obj;
void (*m_func)(void *,T *,U *j);
};
