C ++ 11. Capturing a Lambdas item variable, "this" is a pointer in an STL list

I have a simple event system with a simple button. This system is driven by a list of std :: function with assigned lambdas inside.

Here is the complete class of buttons:

class Button {

private:

    Square square;
    Text label;
    bool hovered = false;
    std::function <void ()> on_mouse_enter;
    std::function <void ()> on_mouse_leave;

public:

    Button (const Square& SQUARE, const Text& LABEL):
        square {SQUARE},
        label {LABEL}
    {
        on_mouse_enter = [this] () {
            square.set_color(1, 1, 1);
        };

        on_mouse_leave = [this] () {
            square.set_color(0, 0, 0);
        };
    }

    std::function <void (const Render&)> get_rendering() {
        return [this] (const Render& RENDER) {
            RENDER.draw(square);
            RENDER.draw(label);
        };
    }

    std::function <void (const Point&)> get_updating() {
        return [this] (const Point& CURSOR) {
            if (not hovered) {
                if (is_including(square, CURSOR)) {
                   hovered = true;
                   if (on_mouse_enter)
                       on_mouse_enter();
                }
            } else
                if (not is_including(square, CURSOR)) {
                   hovered = false;
                   if (on_mouse_leave)
                       on_mouse_leave();
                }
        };
    }

};

      

        
        
        
      

    

And I add a button like this to the event manager, for example:

Button button {/*SOME_PARAMS_HERE*/};

mngr.push_to_render(button.get_render());
mngr.push_to_updater(button.get_updater());

      

        
        
        
      

    

It works fine, no problem, on_mouse_enter and on_mouse_leave work as intended.

But if I do something with the wrapper of the STL container like:

std::list <Button> sb;

sb.emplace_back(Button {/*SOME_PARAMS_HERE*/});

mngr.push_to_render(sb.back().get_render());
mngr.push_to_updater(sb.back().get_updater());

      

        
        
        
      

    

The whole thing is falling apart. on_mouse_enter and on_mouse_leave don't work like that.

When outputting debug messages I can see that the square accessed in this case in on_mouse_enter and on_mouse_leave are not the squares they should be, I can see that this is not what it should be.

What is wrong with such seizures and how can it be solved?
