I want one object to call another object back. I can´t get the syntaks right. Can anyone help.

If you want anybody to help you, you''ll have to give us more info. Which language, what object, etc...?

Dormeur

Sorry

I use C++.

Supose I have two classes. Class A does something and is supossed to tell Class B how things are progressing (like a loader bar).




class A
{
public:
void DoSomething(void *fp()); //should call B->UpdateMe()
}

class B
{
public:
void CallDoSomething(); //calls DoSomething() in class A
void UpdateMe(int update);
}




I hope I´m making myself clear now...


1. What is the correct parameter syntaks for DoSomething() ?

2. How should it be called from class B->CallDoSomething() ?
( A->DoSomething(this->UpdateMe()) ???)

You could just make it in a easier way. Let's say you have a class A, coded like this :

    class A{protected:	B *	myB;public:	void AttachTo( B * b);	void MakeStuff();}  [/source]First, you attach your object A to a previously created object B and then you can easily update your "progress bar" (or anything else) like that :[source]void A::attachTo( B * b){	myB = b;}void A::MakeStuff(){	// Make your stuff		b->Update()}void pseudoMain(){	A	a;	B	b;	a.attachTo( &b);	while(...)		a.MakeStuff();}    

That's all!
