i need to read all the groups in my ini file... how can i do this?

this is my ini file

Code:

---

[sys_1]
val1 = 10
val2 = 23
val3 = 23
 
[sys_2]
val1 = 56

this is the code im using

Code:

---

QSettings settings(QDir::currentPath() + "/test.ini", QSettings::IniFormat);
    settings.beginGroup("SYS_1");// How to change this to read 'n' number of groups ??
    const QStringList childKeys = settings.childKeys();
 
    QStringList Keys;
    QStringList values;
 
 
    foreach (const QString &childKey, childKeys)
    {
        Keys << childKey;
        values << settings.value(childKey).toString();
    }
    settings.endGroup();

---

settings.beginGroup("SYS_1");// How to change this to read 'n' number of groups ??

You can read all group using QSettings::childGroups()
for example

Code:

---

QSettings settings(QDir::currentPath() + "/test.ini", QSettings::IniFormat);
Q_FOREACH (QString group, settings.childGroups()) {
    settings.beginGroup(group);
    const QStringList childKeys = settings.childKeys();
 
    QStringList Keys;
    QStringList values;
 
    foreach (const QString &childKey, childKeys)
    {
        Keys << childKey;
        values << settings.value(childKey).toString();
    }
    settings.endGroup();
}

---

or, if you read ONLY "sys_*" groups

Code:

---

QSettings settings(QDir::currentPath() + "/test.ini", QSettings::IniFormat);
Q_FOREACH (QString group, settings.childGroups()) {
    if (!group.startsWith("sys_"))
        continue;
 
    settings.beginGroup(group);
    const QStringList childKeys = settings.childKeys();
 
    QStringList Keys;
    QStringList values;
 
    foreach (const QString &childKey, childKeys)
    {
        Keys << childKey;
        values << settings.value(childKey).toString();
    }
    settings.endGroup();
}

How Can i add a new Group using QSettings??

my ini is this

Code:

---

[sys_1]
val1 = 10
val2 = 23
val3 = 23
 
[sys_2]
val1 = 56
val2 = 2
val3 = 27
 
[sys_3]
val1 = 84
val2 = 65

i need to add [sys_4]..

Using setValue

Code:

---

QSettings settings (...);
 
settings.addGroup("[sys_4]");
settings.setValue("val1", 10);
settings.setValue("val2", 20);
settings.setValue("val3", 30);
settings.endGroup();
