[quote author="imrrk" date="1306387710"]hello Volker,Can u give me some hints then..[/quote]
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....

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();

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,
LeonP.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,
