/// sf::Event holds all the informations about a system event

///
/// A sf::Event instance contains the type of the event
/// (mouse moved, key pressed, window closed, ...) as well
/// as the details about this particular event. Please note that
/// the event parameters are defined in a union, which means that
/// only the member matching the type of the event will be properly
/// filled; all other members will have undefined values and must not
/// be read if the type of the event doesn't match. For example,
/// if you received a KeyPressed event, then you must read the
/// event.key member, all other members such as event.MouseMove
/// or event.text will have undefined values.
///
/// Usage example:
/// \code
/// sf::Event event;
/// while (window.pollEvent(event))
/// {
/// // Request for closing the window
/// if (event.type == sf::Event::Closed)
/// window.close();
///
/// // The escape key was pressed
/// if ((event.type == sf::Event::KeyPressed) && (event.key.code == sf::Keyboard::Escape))
/// window.close();

/// // The window was resized
/// if (event.type == sf::Event::Resized)
/// doSomethingWithTheNewSize(event.size.width, event.size.height);
