          To quote myself:

          [quote author="Volker" date="1306322983"]I personally would do something with the color read from the settings....[/quote]

          Oh, and that debugger thingie likes breakpoints, you know...

          I would be alarmed if it did not stop at a certain point....

            @void MainWindow::writeSettings()
            {
            QSettings settings;//("company name", "project");

            settings.beginGroup("pushbutton");
            settings.setValue("size", size());
            settings.setValue("pos", pos());
            settings.setValue("mytext",ui->pushButton->styleSheet());
            settings.setValue("mytext1",ui->pushButton_2->styleSheet());
            settings.setValue("mytext2",ui->pushButton_3->styleSheet());
            //QColor r("red");
            //r.name();

            //settings.setValue("color",r.name());

            settings.setValue("state", saveState());
            qDebug()<<r.name();
            settings.endGroup();
            }

            void MainWindow::readSettings()
            {
            QSettings settings;//("Plackal", "restoreproject");

            settings.beginGroup("pushbutton");
            resize(settings.value("size", QSize(400, 400)).toSize());
            move(settings.value("pos", QPoint(200, 200)).toPoint());
            a=settings.value("mytext").toString();
            b=settings.value("mytext1").toString();
            c=settings.value("mytext2").toString();
            //ui->pushButton->setText(a);
            //QColor r=settings.value("color").toString();
            ui->pushButton->setStyleSheet(a);
            ui->pushButton_2->setStyleSheet(b);
            ui->pushButton_3->setStyleSheet(c);
            //ui->pushButton->autoFillBackground(r);
            QByteArray state = settings.value("state", QByteArray()).toByteArray();
            restoreState(state);
            //resize(size);
            //move(pos);
            qDebug("set");
            settings.endGroup();

            }@

              Hi All,

              Although this thread is generating too much spam I think the topic about QSettings is interesting. I was unable to find a simple QSettings example here in our wiki nor in Forum Nokia so I decided to create a new article:
              "How to Use QSettings":http://developer.qt.nokia.com/wiki/How_to_Use_QSettings I have tested the example on my Nokia E7 and I will improve the article in the coming days :)

              Best regards,
              Leon

              P.S.

              Please note that the example contains very basic GUI without any layouts. My idea was just to focus on the basic usage of QSettings.

                I found the API docs on "QSettings":http://doc.qt.nokia.com/4.7/qsettings.html with the example snippets to be sufficient.

                    Please excuse me if you find the article useless. Qt documentation is very good and there are examples for almost everything but I think it is always good to have another example application at Qt Dev Net wiki.

                    10x,

                      Oh, no insult intended. Every wiki article with a working snippet adds value to DevNet, IMHO.

                        Hi,

                        QSettings is used indirectly in the examples of Qt docs, e.g. in "Main Window examples":http://doc.qt.nokia.com/4.7/mainwindows-application.html for storing application settings:

                        [quote]
                        @
                        void MainWindow::readSettings()
                        {
                        QSettings settings("Trolltech", "Application Example");
                        QPoint pos = settings.value("pos", QPoint(200, 200)).toPoint();
                        QSize size = settings.value("size", QSize(400, 400)).toSize();
                        resize(size);
                        move(pos);
                        }

                        void MainWindow::writeSettings()
                        {
                        QSettings settings("Trolltech", "Application Example");
                        settings.setValue("pos", pos());
                        settings.setValue("size", size());
                        }
