SFML Window Not Rendering Shape - c++

Question

#include <SFML/Graphics.hpp>
int main()
{
sf::RenderWindow window(sf::VideoMode(200, 200), "SFML works!");
sf::CircleShape shape(100.f);
shape.setFillColor(sf::Color::Green);
while (window.isOpen())
{
sf::Event event;
while (window.pollEvent(event))
{
if (event.type == sf::Event::Closed) {
window.close();
}
}
window.clear();
window.draw(shape);
window.display();
}
return 0;
}
This is directly from the tutorial's page, and I've checked and rechecked, so I know this is not a syntax or linker error.
When I run this program, I get a window whose contents are the same as whatever the place it is located in. Yet, if I remove the window.draw(shape) command, I see a black window, like I should.
I'm compiling on Windows 7 (32 bit) using mingw32-g++.exe (4.7.1). Oh, and it's the same if I compile debug or release and static or dynamic, so that's not the problem either.

Answer 1

Your code is correct, but to me it looks like you need to set the position of your circle. I maybe wrong here but the position could be any value and that is why it isn't displaying.
Could you try updating your code to this please.
sf::CircleShape shape(100.f);
shape.setFillColor(sf::Color::Green);
shape.setPosition(50f, 50f);
shape.setScale(2,2); // You can remove this line if you want to, I just put it there for debugging
while (window.isOpen())
{
...
Here is the SFML documentation for setPosition (http://www.sfml-dev.org/documentation/2.0/classsf_1_1Transformable.php#a4dbfb1a7c80688b0b4c477d706550208)
Here is the SFML documentation for setScale (http://www.sfml-dev.org/documentation/2.0/classsf_1_1Transformable.php#aaec50b46b3f41b054763304d1e727471)
Let me know if that fixes your problem.
