Read empty groups with QSettings

[phenoboy]

It seems impossible to read top level group names that are empty.

QSettings s(fileName, QSettings::IniFormat);
s.setIniCodec("UTF-8");

QStringList l2=s.allKeys();
QStringList l=s.childGroups();


INI file:

[0]

[1]

[2]

In this code lists l2 and l are empty. Is there any way to read top level groups that are empty?

The lists are empty because there are no keys to read in an empty group.

What are you trying to achieve here?

Thanks for you answer.

I'm trying to read top-level group names. In my example I expect the function QSettings::childGropus return a list of 0,1 and 2. I haven't used beginGroup function so I expect childGroups to get group names from top-level of the file.

Should childKeys() return all top-level keys or have I misunderstood something ? It looks like QSettings will discard groups that are empty

QSettings is about storing settings. If a group has no keys, there is no data in the group thus logically the group might not exist at all. You were asked why you had been trying to access empty groups.
