      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());@

                I should check these lines..?

                            Hi imrrk,

                            one suggestion:

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

                            Regards
