QSettings mysteries

[giusepped]

I have simply

void mainWindow::readSettings()
{
 
        QSettings settings("GDEM","Rubic 1.0");
        settings.beginGroup("mainWindow");
        resize(settings.value("size",QSize(400,400)).toSize());
        move(settings.value("pos",QPoint(200,200)).toPoint());
        if (settings.contains("splitterSize"))
              splitterSettings = (settings.value("splitterSize").toByteArray());
	#ifdef DEBUG
        qDebug()<<"createConnection, database loaded ok:"<<databaseName<<settings.value("pos").toString().isEmpty()
                <<settings.contains("size");
        #endif
        settings.endGroup();
 
        settings.beginGroup("database");
        if (settings.contains("databaseName") && (!settings.value("databaseName").toString().isEmpty())) {
                databaseName = settings.value("databaseName").toString();
		currentDatabase = databaseName;
 
				}
        else
                databaseName="rubric.db";
 
 
        settings.endGroup();
	#ifdef DEBUG
        qDebug()<<"settings loaded ok:"<<settings.value("size").toString();
        #endif
	settings.sync();
}

void mainWindow::readSettings()
{
	
        QSettings settings("GDEM","Rubic 1.0");
        settings.beginGroup("mainWindow");
        resize(settings.value("size",QSize(400,400)).toSize());
        move(settings.value("pos",QPoint(200,200)).toPoint());
        if (settings.contains("splitterSize"))
              splitterSettings = (settings.value("splitterSize").toByteArray());
	#ifdef DEBUG
        qDebug()<<"createConnection, database loaded ok:"<<databaseName<<settings.value("pos").toString().isEmpty()
                <<settings.contains("size");
        #endif
        settings.endGroup();

        settings.beginGroup("database");
        if (settings.contains("databaseName") && (!settings.value("databaseName").toString().isEmpty())) {
                databaseName = settings.value("databaseName").toString();
		currentDatabase = databaseName;
	
				}
        else
                databaseName="rubric.db";
	

        settings.endGroup();
	#ifdef DEBUG
        qDebug()<<"settings loaded ok:"<<settings.value("size").toString();
        #endif
	settings.sync();
}

To copy to clipboard, switch view to plain text mode 

and

void mainWindow::writeSettings()
{
        QSettings settings("GDEM","Rubi 1.0");
        settings.beginGroup("mainWindow");
        settings.setValue("pos",pos());
        settings.setValue("size",size());
        settings.setValue("splitterSize",mainSplitter->saveState());
        settings.endGroup();
 
        settings.beginGroup("database");
        settings.setValue("databaseName",currentDatabase);
        settings.endGroup();
	settings.sync();
 
}

void mainWindow::writeSettings()
{
        QSettings settings("GDEM","Rubi 1.0");
        settings.beginGroup("mainWindow");
        settings.setValue("pos",pos());
        settings.setValue("size",size());
        settings.setValue("splitterSize",mainSplitter->saveState());
        settings.endGroup();

        settings.beginGroup("database");
        settings.setValue("databaseName",currentDatabase);
        settings.endGroup();
	settings.sync();

}

To copy to clipboard, switch view to plain text mode 

and

void mainWindow::closeEvent(QCloseEvent *event)
{	 writeSettings();
 
	QSqlDatabase database = QSqlDatabase::database();
	QSqlDatabase::removeDatabase();
        event->accept();
}

void mainWindow::closeEvent(QCloseEvent *event)
{	 writeSettings();
	
	QSqlDatabase database = QSqlDatabase::database();
	QSqlDatabase::removeDatabase();
        event->accept();
}

To copy to clipboard, switch view to plain text mode 

I checked the file Rubic 1.0

[mainWindow]
pos=@Point(200 200)
size=@Size(400 400)
splitterSize=@ByteArray(\0\0\0\xff\0\0\0\0\0\0\0\x2\0\0\0^\0\0\0\xa1\x1\0\0\0\x6\x1\0\0\0\x2)
 
[database]
databaseName=rubric.db

[mainWindow]
pos=@Point(200 200)
size=@Size(400 400)
splitterSize=@ByteArray(\0\0\0\xff\0\0\0\0\0\0\0\x2\0\0\0^\0\0\0\xa1\x1\0\0\0\x6\x1\0\0\0\x2)

[database]
databaseName=rubric.db

To copy to clipboard, switch view to plain text mode 

and if I resize the window the values accordingly change.
But: if I re-run the application the values are not loaded.
Why?

I call readsettings in the constructor

Sorry,
I mitaken the file name (readSettings and writeSettings)
