hello everybody
I'm creating a simple application that should be a 7 segment clock, everything works ok when I try this codesnippet
Qt Code: 
  1. QString hour=QString::number(time.currentTime().hour());
  2.         QString min=QString::number(time.currentTime().minute());
  3.         QString sec=QString::number(time.currentTime().second());
  4.         scene->clear();
  5.         for(int i=0;i<6;i++)
  6.         {
  7.             if(i%2==0 && i>0)
  8.                 this->designPoints(i);//I design the dots so that the clock looks something like this 00:00:00
  9.             QString appoggio;
  10.             if(i==0 || i ==1)
  11.                 appoggio=ImpostaAppoggio(i,hour);//sets the value of appoggio
  12.             if(i==2 || i==3 )
  13.                 appoggio=ImpostaAppoggio(i,min);
  14.             if(i==4 || i ==5)
  15.                 appoggio=ImpostaAppoggio(i,sec);
  16.             DisegnaNum(appoggio,i);//I design the seven segments

but when I try this
Qt Code: 
  1. for(int j=0;j<1000;j++)
  2.     {
  3.         QString hour=QString::number(time.currentTime().hour());
  4.         QString min=QString::number(time.currentTime().minute());
  5.         QString sec=QString::number(time.currentTime().second());
  6.         scene->clear();
  7.         for(int i=0;i<6;i++)
  8.         {
  9.             if(i%2==0 && i>0)
  10.                 this->designPoints(i);
  11.             QString appoggio;
  12.             if(i==0 || i ==1)
  13.                 appoggio=ImpostaAppoggio(i,hour);
  14.             if(i==2 || i==3 )
  15.                 appoggio=ImpostaAppoggio(i,min);
  16.             if(i==4 || i ==5)
  17.                 appoggio=ImpostaAppoggio(i,sec);
  18.             DisegnaNum(appoggio,i);
  19.         }
  20.     }

no errors or warning occur but no window is showing up and I can't figure out what's going wrong! can someone help?
