General / Re: Unhandled Exception when trying to draw a Text object from within a Drawable

I am using x86 libs.
I am using VS 2012, and I downloaded the SFML 2.3 package for VS 2012.
I am only using debug mode for the time being.
I don't think I am using old headers. Only those that came with the SFML 2.3 package for VS 2012.

Edit: I just tested this code on another computer with a different version of Visual Studio, and I got the same error. This makes me think the problem is with my code somewhere.

General / Unhandled Exception when trying to draw a Text object from within a Drawable

« on: May 13, 2015, 11:21:04 pm »

I am receiving an unhandled exception error when trying to draw a Text object. Here is the error message:

Unhandled exception at 0x59085815 (sfml-graphics-2.dll) in Program.exe: 0xC0000005: Access violation reading location 0x3F800058.

The thing is, I am telling main to draw a Drawable object (InputBox), which is telling another Drawable object (Button) to draw the Text. If I replace the Text object with another Drawable, such as a CircleShape, the program works. Also, if I draw the Button in main directly, it works as well. Here is my code:

My main Program

int main()
{
    sf::RenderWindow window(sf::VideoMode(800, 600), "My window");
        InputBox inputBox;
    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }
        window.clear(sf::Color::Black);
        window.draw(inputBox);
        window.display();
    }

    return 0;
}

InputBox class

class InputBox : public sf::Transformable, public sf::Drawable
{
public:
        InputBox()
        {
                button = Button();
        }
        virtual void draw(sf::RenderTarget &target, sf::RenderStates states) const
        {
                states.transform *= getTransform();
                target.draw(button, states);
        }
private:
        Button button;
};

Button class

class Button : public sf::Transformable, public sf::Drawable
{
public:
        Button()
        {
                font.loadFromFile("arial.ttf");
                text.setFont(font);
                text.setString("Button");
        }
        virtual void draw(sf::RenderTarget &target, sf::RenderStates states) const
        {
                states.transform *= getTransform();
                target.draw(text, states);
        }
private:
        sf::Font font;
        sf::Text text;
};
