How to find the Qsettings is exists or not?

[Mathan]

Hi,

I would like to setup an Qsetting which stores like username, theme the user used.
Before accessing the Qsetting, I want to Qsetting is present or I will create a new considering user login first time.



Code snippet:
QCoreApplication::setOrganizationName("gghh");
QCoreApplication::setOrganizationDomain("gghh.COM" );
QCoreApplication::setApplicationName("Library");
QCoreApplication::setApplicationVersion("1.0");

QSettings qAppSetUser;
qAppSetUser.setValue("UserName",pstrUserName);
qAppSetUser.setValue("Password",pstrPassword);
qAppSetUser.setValue("NamedUserName","NamedUserNam e");
qAppSetUser.setValue("AccessLevel","Level1");

Query: How to check the Qsetting - qAppSetUser is already exist or not/

Thanks in advance.

You don't have to do the check. Just open QSettings object and try to read value for e.g. "UserName" key. If it's not there then the file is not present.
