SFML won't open a window?

Question

So, as the title suggests, I am trying to create a simple Window using SFML 1.6 in CodeBlocks (MinGW v.4.7.0) on Windows 7 (no, I'm not using an ATI GPU).

This is the code:

#include <SFML/Window.hpp>

int main()
{
    sf::Window App(sf::VideoMode(800, 600, 16), "SFML Window");
    App.Display();

    return 0;
}

Whenever I try to run this code, it just says Program.exe is not responding and has to be shutdown using Close this program . The funny thing is, the first tutorial offered on the SFML tutorial website (the one utilizing sf::Clock in a console) works, so the libraries are loaded properly.

Can someone help me find the cause of the error I'm getting?

Other than the crash, I get no compiler or application errors.

Answer 1

The problem is that you haven't created the main loop which polls for events and handles OS messages. Append this to main() (yes, this is a snippet from the SFML documentation):

while (App.IsOpened())
{
   // Process events
   sf::Event Event;
   while (App.GetEvent(Event))
   {
      // Close window : exit
      if (Event.Type == sf::Event::Closed)
         App.Close();
   }

   // Clear the screen
   App.Clear();

   // Put your update and rendering code here...

   // Update the window
   App.Display();
}

It is therefore not necessary for you to call App.Display() after you create the window.

For those who want the whole thing, this is a snippet extracted from the SFML website .

#include <SFML/Window.hpp>

int main()
{
    sf::Window window(sf::VideoMode(800, 600), "SFML Window");

    // run the program as long as the window is open
    while (window.isOpen())
    {
        // check all the window's events that were triggered since the last iteration of the loop
        sf::Event event;
        while (window.pollEvent(event))
        {
            // "close requested" event: we close the window
            if (event.type == sf::Event::Closed)
                window.close();
        }
    }    

    return 0;
}

You will get:
