How to Read Value from a text file and Iterate?

YDYD

Hi all,

I have a .txt file with 6 random integer as following layout:

52
241
40
180
7
120

I used the following code to read from the text file.
@void Dialog::loadInitValue()
{
QString list;
QString path="/mnt/rd/hsv.txt";
QFile valueHSV(path);
if(!valueHSV.open(QIODevice::ReadOnly|QIODevice::Text))
{
qDebug() << "cannot open file for reading"<<endl;
return;
}

QTextStream hsv(&valueHSV);
while(!hsv.atEnd())
{
    list.append(hsv.readLine());
    if(list.isNull())
        break;
     qDebug()<<list;
}
foreach(QString str, list)
{
    int value = str.toInt();
    qDebug()<<value;
}

return;

}@

for "list", i will get:
"52"
"241"
"40"
"180"
"7"
"120"

for "value", i will get:
5
2
2
4
1
4
0
1
8
0
7
1
2
0

I would like to store each of the value into different variables.
How could i achieve this?

hii

Line 3 : -QString list;
Update by QStringList list;
Line 16: -list.isNull());
Update by list.isEmpty();

hope it helps

You can make it more simple if the file format given by is the only format.

@ QString path="hsv.txt";
QFile valueHSV(path);
if(!valueHSV.open(QIODevice::ReadOnly|QIODevice::Text))
{
qDebug() << "cannot open file for reading"<<endl;
return 1;
}

while(!valueHSV.atEnd()){
   QString val =  valueHSV.readLine();
   qDebug() << val.toInt();
}@

Iterating through a QStringList should best be done with a const_iter variable.
Or simply take the first element, and send via debug, but then you loose the data.
