Incomprehensible bug

Hey guys, i have the following code:

Code:

---

bool QueryNewGame(ConfigFile &pConfig, sf::RenderWindow *pApp)
{
    pApp->Clear();
    sf::Font GUIFont;
    if( !GUIFont.LoadFromFile(pConfig.read<std::string>("gui_font"))) return false;

    sf::String Str("", GUIFont, pConfig.read<int>("gui_text_size"));
    sf::Event Event;
    time_t StartTime = time(NULL);
    int EndTime = pConfig.read<int>("game_continue_timer");

    while( difftime(time(NULL), StartTime ) < EndTime )
    {
        int ElapsedTime = difftime(time(NULL), StartTime);
        std::stringstream SS;
        SS << "PRESS SPACE TO RESTART THE GAME, PRESS ESCAPE TO EXIT.\n" << ElapsedTime;
        Str.SetText(SS.str().c_str());
        Str.SetColor(sf::Color(255, 0, 0));
        SS.str("");
        Str.Move(pApp->GetWidth()/10, pApp->GetHeight()/2);
        sf::Event Event;
        pApp->GetEvent(Event);

            //Window closed
            if(Event.Type == sf::Event::Closed)
                return false;

            //Escape pressed
            if( (Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::Escape) )
                return false;

            if( (Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::Space) )
                return true;

        pApp->Draw(Str);
        pApp->Display();
    }
    return false;
}

Which *should* output the text string to the screen, along with the elapsed time in seconds. For some reason the elapsed time that reaches the screen is always 0. I have run this through GDB and the ElapsedTime variable gets incremented properly, with the amount of seconds since the start of the function. GDB won't let me look into the stringstream however, for some reason it's just an "unknown type" so i suspect that is where the problem is, am i using this stringstream all wrong?

I don't recognize the sf namespace, although it's clear that it's the GUI. I can check the standard stuff, and that works fine:

Code:

---

#include <iostream>
#include <sstream>
#include <unistd.h> //I'm using sleep to simulate whatever it is that you're trying to do
#include <ctime>
int main(void) {
    time_t StartTime = time(0);
    int EndTime = 15;
    while (difftime(time(0), StartTime) < EndTime) {
        int ElapsedTime = difftime(time(0), StartTime);
        std::stringstream SS;
        SS << "PRESS SPACE TO RESTART\n" << ElapsedTime;
        std::cout << SS.str().c_str() << std::endl;
        sleep(1);
    }
    return 0;
}

That's compilable, and it works wonderfully here. Perhaps you can try adding your sf:: code one line at a time to this and see what happens.

What GUI/toolkit is this for?

I'm using SFML in the above code, i figured that it was my use of the std lib that was off, but compiling and running tabstops code yields proper results so the problem must be with SFML. I'll take it to their forums then, thanks for the clarification.

It boggles my mind that they used sf instead of sfml as the namespace name.

Why? Is there a name conflict with something important that i've missed?

Normally people only use an abbreviation if the name is long. And sfml is not that long.
