Can't get depth testing to work in OpenGL

Question

I use SFML to create the window.

In this screenshot the cube should be behind the pyramid but it just doesn\'t work.

Answer 1

In latest version of SFML WindowSettings replaced by ContextSettings. Depth settings can be configured as.

//Configuring SFML window
sf::ContextSettings window_settings;
window_settings.depthBits         = 24; // Request a 24-bit depth buffer
window_settings.stencilBits       = 8;  // Request a 8 bits stencil buffer
window_settings.antialiasingLevel = 2;  // Request 2 levels of antialiasing

// Opening SFML window
sf::Window window(sf::VideoMode(800, 600), "Title", sf::Style::Resize | sf::Style::Close, window_settings);
glewExperimental = GL_TRUE;

// Initializing glew and openGL
glewInit();
glViewport(0, 0, 800, 600);

// Enabling Depth
glEnable(GL_DEPTH_TEST);
