about class's and 'events'

[Cambalinho]

No matter how many times you repeat it, your code makes no sense, therefore your question makes no sense. Look at what I posted earlier. If that's now what you're trying to do, explain using words, not code, exactly what you're trying to do.

thanks for tell me that. thanks

so i must use virtual functions.

It depends upon what you want to achieve! You're trying to jump ahead and attempting to do things without having the basic underlying knowledge. You need to acquire the basic knowledge of c++ so that you would know whether you need virtual functions or derived classes or pure virtual etc. Learn the basics of the c++ language (including classes) before you try to do to much.

what i'm trying to do is events with class's. thats why i use variables class for use that function.

I don't see any that could look like "events" in your code snippets. Nor is there anything similar to "events" in your explanations.
