Issues with QSettings::value()::toInt()

spode

Why can not i obtain data i need from this class, though it does not return errors and is similar than the snippet provided by QSettings (editor)?

@
#include "programsettings.h"

#include <QSettings>
#include <QVariant>
#include <QDesktopWidget>
#include <messaggioantipanico.h>
#include <QDebug>

ProgramSettings::ProgramSettings()
{
}

int ProgramSettings::getIngrandimento()
{
QSettings s("SeiFreud", "Tecnophobie");
int i = s.value("ingrandimento", QVariant::fromValue(1)).toInt();
qDebug()<< "ingrandimento corrente: " + i;
return i;
}

void ProgramSettings::setIngrandimento(const int nvalue)
{
qDebug()<<"ingrandimento incrementato di uno: " + nvalue;
if(nvalue > 0 && nvalue < 4)
{
QSettings s("SeiFreud", "Tecnophobie");
s.setValue("ingrandimento", QVariant::fromValue(nvalue));

    emit ingrandimentoChanged(nvalue);
    qDebug()<<"signal";
}
else
{
    MessaggioAntiPanico a("Non è possibile cambiare ulteriormente l' ingrandimento!");
    a.show();
}

}

QRect ProgramSettings::getDesktopDims()
{
QDesktopWidget * d = new QDesktopWidget();
return d->screenGeometry(-1);
}

QSize ProgramSettings::getDesktopDimsAsQSize()
{
QDesktopWidget * d = new QDesktopWidget();
return QSize(d->width(), d->height());
}

int ProgramSettings::getDesktopHeight()
{
return ProgramSettings::getDesktopDims().width();
}

int ProgramSettings::getDesktopWidth()
{
return ProgramSettings::getDesktopDims().height();
}

void ProgramSettings::addIngrandimento()
{
qDebug()<<"addIngrandimento";
qDebug()<<"ingrandimento non aggiornato: " + this->getIngrandimento();
this->setIngrandimento(this->getIngrandimento() + 1);
}

void ProgramSettings::reduceIngrandimento()
{
this->setIngrandimento(this->getIngrandimento() - 1);
}

Can you explain why you are adding the integers to a string as you do in a number of your qDebug() output?

E.g.
line 17
line 23
line 64

That is right!

is there no way to cript information of qsettings...or to hide them?

You did not answer my question.

What do you expect as output from line 17 ?

Oh. Excuse me. Nothing, becouse i should have written QString::setNum(I).
In fact it is right! :)
