QSettings not returning keys of the predefined .ini file

@thippu Please see that I edited my post.

@thippu said in QSettings not returning keys of the predefined .ini file:

iniSettings->setPath(QSettings::IniFormat,QSettings::UserScope,filename);// filename is a global variable here
//If I do the following codes
qDebug()<<iniSettings->group();//returns " "
qDebug()<<iniSettings->allKeys();//returns ()

you need to call QSettings::beginGroup() before reading/writing
also you can check if the return value of QFile::exists(filename) if the application really can find your ini-file.

[thippu]

@aha_1980 Yes, I saw it, and I'm sure there is no filename initialization in the constructor, it happens through the QFileDialog.getOpenFilename();
and for double sure I do if(!QFile(filename).exists()).

[thippu]

@raven-worx Yes, I did qDebug()<<QFile(filename).exists(); it returned me true.

[thippu]

@raven-worx for beginGroup() , iniSetting->beginGroup("[");// I doubt it will work as per .ini filestructure?

[raven-worx]

@thippu
with respect to your ini file from your first post you should call:

iniSettings->beginGroup("Personal");
iniSettings->value("Age");
iniSettings->endGroup();

or alternatively (if you don't have a group set!):

iniSettings->value("Personal/Age");

@thippu

And in addition to what @raven-worx says, you need to use this constructor if you want to specify the filename.

Otherwise QSettings calculates the filename itself.

[thippu]

@raven-worx Yes bro, in that .ini example, [groupname] // may grow and I want to scan them dynamically, how to do it?

[raven-worx]

@thippu
yes i just wanted to add as @aha_1980 said.
Use the mentioned constructor, since in your case it is not required to mess with the scopes.

[thippu]

@raven-worx okay, I have included in the constructor itself.
code: iniSettings=new QSettings(filename,QSettings::IniFormat,this);

[raven-worx]

@thippu
and? it's working now?

[thippu]

@raven-worx bro, in .ini

) can grow, I want to scan them dynamically, so what to include in

beginGroup() ?, please help me.

[thippu]

@raven-worx Yes, bro working. failure was the happing because of the constructor, after setting it properly it working now, I did
I can't thank enough to guys @raven-worx , @aha_1980

qDebug()<<iniSettings->childGroups();//returns all the heading names````

[raven-worx]

@thippu
with the usage of the right Constructor your ini-file should be read correctly now.
So now you can use QSettings::childGroups() to traverse all groups and read the values as i described above or with the use of QSettings::beginGroup() and QSettings::childKeys()

foreach( QString group, iniSettings->childGroups() )
{
     // process group
     iniSettings->beginGroup(group);
         foreach( QString key, iniSettings->childKeys() )
         {
                QVariant val = iniSettings->value(key);
                // process val
         }
     iniSettings->endGroup();
}

@raven-worx
uh hu, using deprecated syntax/macros, shame on you ;-)

[thippu]

@raven-worx Sure bro, I will use this code to create group and contents of the group.

yes, i am still too lazy for such a convenient function to deprecate it also in my head ;)
