            Hi imrrk,

            one suggestion:

            look at the docs of QColor and QSettings.
            Then you should find it.

            Regards

                whether it should be done this way..

                QColor r(settings.value(“color”).toString(),ui->pushbutton->setcolor(r));

                                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.

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