Another problem with Text

[ravenheart]

now i want my programm to show the time it is running

i did it something like

Code: [Select]


main()
{
      String Text;
      Text.SetFont(sf::Font::GetDefaultFont());
      Text.SetSize(20);

      Clock Timer;    

      while running
      {
                     events
                     {
                     }
                     Text.SetText(Timer.GetEclapsedTime();  converted to string
                     Draw Text;
      }

}


now i dont want endless strings one after one , i only want ONE text to be shown, showing the current runnig-time

whats my mistake?

[ravenheart]

oh oh , after thinking bout it i believe i found the answer, with my conversion
osstream out;
 out << blablabla;
string str = out.str();

the string gets longer and longer becasue of out << ,...

well thats not a sfml problem anymore but there was something with ios:flags as solution

2 mins of googling and i found what i was looking for^^
 ( i´m glad i remember anything since the days i learnd c++ =)

out << seekp(0);

was all i needed to add

that shouldn't be necessary ... this is the function i use and it has worked well for quite some time

Code: [Select]


template<class T>
std::string ToString(T val)
{
    std::stringstream ss;
    ss << val;
    return ss.str();
}


you can also go the C way
char buf[64];
sprintf(buf, "%d%, val);

but then you need to watch out for buffer overruns and keeping track of what type val actually is .. so the stringstream version is definitely recommended
