Loading and saving a class using qsettings - c++

Question

I have an ini file as shown
[Profiles]
hh\Ta=20
hh\Te=48
hh\Texp=38
hh\lim1=0
hh\lim2=0
hh\offset=0
hh\profilename=hh
tt\Ta=20
tt\Te=48
tt\Texp=38
tt\lim1=0
tt\lim2=0
tt\offset=0
tt\profilename=hh
I'm trying to load it, but I get all the data as zeros, like Ta Te Texp,..etc
The file is saved correctly but loading the values back is not working.
Is it a problem with setting the group,..etc ?
here is my load and save mechanism
void Method::loadFrom(Settings &set, bool ownGroup)
{
set.beginGroup("Profiles");
foreach (const QString &group, set.childGroups()) {
set.beginGroup(group);
Profile *profile = new Profile();
profile->setObjectName(group);
profile->loadFrom(set);
set.endGroup();
m_currentProfile->m_Profiles << profile;
}
set.endGroup();
EraObject::staticLoadFrom(set, this, ownGroup);
}
void Method::saveTo(Settings &set, bool ownGroup, bool force)
{
set.beginGroup("Profiles");
foreach(Profile * profile, m_currentProfile->m_Profiles) {
profile->saveTo(set);
set.endGroup();
}
set.sync();
EraObject::staticSaveTo(set, this, ownGroup, force);
}
