          Hi imrrk,

          Where do you call readSettings()? It is commented out at the constructor.

            Do you really expect being taken serious when crying like a childish kiddie? Come on, get serious!

            -And look at your code if it is ever able to do what you expect it to do!-

            -Or better: Use a debugger, set breakpoints and step through the code. You will find the error yourself then within seconds.-

            -Hopefully nobody will tell you the solution here, as it has no learning effect.-

            EDIT: wrong read of code, sorry

                  I personally would do something with the color read from the settings....

                    Hi volker thanks for your reply,you mean to say that

                    @QColor r("red");
                    r.name();
                    settings.setValue("color",r.name());@

                                Hi imrrk,

                                one suggestion:

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

                                Regards
