QSettings

[JeanC]

Hello,

I have difficulty supplying arguments to QSettings::value()
This is in the settings file:

[domains]
1=dyndns
 
[dyndns]
type=dyndns

[domains]
1=dyndns

[dyndns]
type=dyndns

To copy to clipboard, switch view to plain text mode 

Now if I call

qDebug() << ini.value("dyndns/type").toString();

qDebug() << ini.value("dyndns/type").toString();

To copy to clipboard, switch view to plain text mode 

I get "dyndns"

But if I call

ini.beginGroup("domains");
QStringList l = ini.allKeys();
for (int i = 0; i < l.size(); i++)
  {
  QString Domain = ini.value(l.at(i)).toString(), S = QString("%1/type").arg(Domain), Type = ini.value(S).toString();
  qDebug() << Domain << S << Type;
  }

ini.beginGroup("domains");
QStringList l = ini.allKeys();
for (int i = 0; i < l.size(); i++)
  {
  QString Domain = ini.value(l.at(i)).toString(), S = QString("%1/type").arg(Domain), Type = ini.value(S).toString();
  qDebug() << Domain << S << Type;
  }

I don't get the Type string, it's empty, I get "dyndns" "dyndns/type" ""

Thanks.

Line #5 should read:

QString Domain = ini.value(l.at(i)).toString(), Type = ini.value("type").toString();

QString Domain = ini.value(l.at(i)).toString(), Type = ini.value("type").toString();

Thanks,
I tried it but Type is still empty.

Ouch, sorry I didn't look at the ini file. This is the correct code:

ini.beginGroup("domains");
QStringList groups;
foreach(const QString &key, ini.childKeys()) groups << ini.value(key).toString();
ini.endGroup();
foreach(const QString &group, groups){
    QString S = QString("%1/type").arg(group), Type = ini.value(S).toString();
    qDebug() << group << S << Type;
}

ini.beginGroup("domains");
QStringList groups;
foreach(const QString &key, ini.childKeys()) groups << ini.value(key).toString();
ini.endGroup();
foreach(const QString &group, groups){
    QString S = QString("%1/type").arg(group), Type = ini.value(S).toString();
    qDebug() << group << S << Type;
}

Line #7 can also be replaced with:

ini.beginGroup(group);
QString Type = ini.value("type").toString();
ini.endGroup();

ini.beginGroup(group);
QString Type = ini.value("type").toString();
ini.endGroup();

Thanks this works, I already had a suspicion about forgetting endGroup().
Nice code, I didn't know about the foreach() yet, I'm gonna study it.
