How to use QSettings to read INI file

[Cantora]

Hi All,

I am trying to use QSettings to read the INI file but I have try few times but still fail to read it :(


The format for INI file is like below:

[System.Setting]
auto_check_update=false
auto_check_mode=weekly

Thanks

Found out the way :)

QString strKey("System.Setting/");
QSettings * settings = 0;
settings = new QSettings( m_strWorkingPath, QSettings::IniFormat );
ret = settings->value( strKey + "auto_check_update", "r").toBool();
strMode = settings->value( strKey + "auto_check_mode", "r").toString();

QString strKey("System.Setting/");

Better use QSettings::beginGroup() and QSettings::endGroup().

Hi, for me
The format for INI file is like below:

[players]
player0name=mike
player0surname=jane
player1name=scootie
...
...

I am trying to use QSettings to read the INI file..
I tried this:
settings = new QSettings("config.ini",QSettings::IniFormat);
settings->beginGroup("players");
int size = settings->beginReadArray("player");
ui->lineEdit_2->setText(QString::number(size)); // this is value-test

for (int index = 0; index < size; ++index)
{
settings->setArrayIndex(index);
ui->choosePlayerBox->addItem(settings->value("name").toString());
}

settings->endArray();
settings->endGroup();

But it doesn`t work..
I tried also:
[players]
player/0/name=mike
player/0/surname=jane
player/1/name=scootie
...
...
But it also doesn`t work..
Any ideas ?
Thanks

try this example:


QSettings settings("test.ini", QSettings::IniFormat);
settings.beginGroup("players");
const QStringList childKeys = settings.childKeys();
foreach (const QString &childKey, childKeys)
qDebug() << settings.value(childKey);
settings.endGroup();

ok, i have ini file like:
[user]
0/name=lukasz
0/wins=3
0/loses=3
1/name=pawel
1/wins=1
1/loses=5
2/name=anna
2/wins=1
2/loses=5

and my code is:



settings = new QSettings("config.ini",QSettings::IniFormat);
settings->beginGroup("user");
QStringList player_number = settings->childGroups(); // returns 0, 1, 2 - OK !
const QStringList childKeys = settings->childKeys(); // should return name, wins, ... right ?
foreach(const QString &childKey, childKeys)
{
ui->choosePlayerBox->addItem(settings->value(childKey).toString()); // should add lukasz, 3, 3, pawel...., but it doesn`t work

}
settings->endGroup();


Any ideas ?

you code will not work, because "0/name" it's a key, not a group.
I suggest you to review format on your ini-file or use xml instead.

Hi
my .ini file is

[System.Setting]
auto_check_update=false
auto_check_mode=weekly

& the code to read is
QString strKey("System.Setting/");
QSettings * settings = 0;
settings = new QSettings( file_path, QSettings::IniFormat );
QString strMode = settings->value( strKey + "auto_check_mode", "r").toString();

no problem with the code compiling & running. when i try to print strMode program is unexpectedly finising.. this is happening with QString, Date (Derived data types). but fine with basic data types like int, float, bool...
using printf to print the values. qDebug is not working in this project. what could be the problem?

Does your derived data type(Date) support QVariant ?
QSettings use QVariant to work.
