How come I get compiler errors when using the STL inside a class?

[Paul McKenzie]

You must have forgotten to #include <list> somewhere. Your solution to your previous problem is not the best -- you should have done this:

#include <list>
#include "Button.h" //my Button class header
class Screen
{
public:
//Stuff Cut Out
private:
std::list<Button*> pButtonList;
//More stuff cut
};



Note the use of std:: instead of the "using" clause. When you use "using", you are introducing a namespace into your header file. Reserve the "using" clause for .CPP files, not headers.
