Memory Leak inside Static Library

[himitsujanai]

Hi guys I'm new here and I'm very thankful because this forum helps me a lot to answer some question in mind when it comes c++ codes.

I need your suggestions on my leak problem in the game that i'm creating. I already found cause of the leak.. it is the vector of pointers which globally declare inside the library(static library).

//******************** Simple Pseudo Code of the game **********************
//Inside the library
//It was extern in Button.h
extern vector<Button*>ButtonList

//and it was used inside the SetupButton member functon of the Button class
Class Button
{
void SetupButton()
}

//And it was declare at the Button.cpp as
vector<Button*>ButtonList

//It was use inside the SetupButton member function so that all available buttons in the game will be added in the list
void Button::SetupButton()
{
... //setup the property of the button
...//setup the position
...//etc.

//then add to the list
ButtonList.push_back( this );

}

And in the game...
#include "Button.h"
Game::Game()
{
Button btnStartButton, btnExitButton;
btnStartButton.SetupButton();
btnExitButton.SetupExitButton();
}

Game::~Game()
{
ButtonList.clear();

... Delete some objects used
}

Game* pGame
void Main()
{
pGame = new Game()
...
...
pGame->RunGame();

delete pGame;
return;
}

Basically this how the setup made .. the game is running and its ok except there is a reported leak.

I'm wondering if what is the best approach to fix the problem. I cant use delete on every elements because they are not dynamically allocated. One solution I made and it will definitely solved the leak is to make the ButtonList vector as member of a class but the changes in the game and in the library will be huge ... Im asking you guys if you have better idea that can save time and lines of codes.

Im thinking if i can use a singleton class as a based class of the button and put the ButtonList vector as static member of this class but im not so familliar with singleton class so i dont know if its possible


Any inputs will be appreciated ...sorry for my bad English

Thanks in Advance
