How to store QSlider position Value into .txt file?

[YDYD]

Hi all,

I would like to get my Qslider position value and store in a txt file. i did as following, my i could not obtain any value.

int h_slide1 = ui->hueSlide1->value();
QFile valueHSV("/home/pi/valueHSV/hsv.txt")
if(!valueHSV.open(QIODevice::WriteOnly| QIODevice::Text))
   return;
QTextStream hsv(&valueHSV);
hsv << h_slide1;

int h_slide1 = ui->hueSlide1->value();
QFile valueHSV("/home/pi/valueHSV/hsv.txt")
if(!valueHSV.open(QIODevice::WriteOnly| QIODevice::Text))
   return;
QTextStream hsv(&valueHSV);
hsv << h_slide1;

To copy to clipboard, switch view to plain text mode 

is this code correct?
