Getting only a particular set of values from a text file!

Lasith

In my QT c++ program I want to load a set of ages into the combo box from a text file when the application is opened! The text file has a set of names also! I want only to get the set of ages into the combo box but I have no idea!

following is my code

{
ui->setupUi(this);

QFile file(QString("%1/Details.txt").arg(QCoreApplication::applicationDirPath()));
qDebug() << QCoreApplication::applicationFilePath();

if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
return;

QTextStream in(&file);
      while (!in.atEnd()) {
          QString age = in.readLine();
          if(age=="Ages"){

          ui->comboBox->addItem( age);
         
          }
          }
   }

following is contents of my text file!
Names
John
Smith
Marie
Anne
Jonathan
Michael
<break>

Ages
5
10
15
20
<break>

for my code I only get [Age] in my combo box but I want to get 5,10,15,20 in the combo box! How can Adjust my code to achieve it?

Maybe you can try this

QTextStream in(&file);
QString sectionName;
while (!in.atEnd()) {
  QString age = in.readLine();
  if (age == "Ages") {
    sectionName = "Ages"; 
    continue;
  }
  if (sectionName == "Ages") {
    ui->comboBox->addItem(age);
  }
}

The other solution is that use uniform format like JSON(http://doc.qt.io/qt-5/qjsondocument.html) or XML(http://doc.qt.io/qt-5/qtxml-module.html) to format your code.
