    I initialized all variables to zero. It works fine now. Thanks.

      One question on graphic visage of the app.
      Please take a look:

      0_1503938077733_1.png

      To me, it looks like a Win 2000 app and old fashioned! People expect more graphical and splendid apps nowadays.
      I think we can make such new-fashioned apps using Qt, can't we?!

      I toyed with that and changed two lines of code from Qt_4_3 to Qt_5_9. But no influence.

      in.setVersion(QDataStream::Qt_4_3);
      out.setVersion(QDataStream::Qt_4_3);
      

      What classes or functions to use to make the app appear new and competitive from the graphics point of view, please?

        It looks like the OS you are running on.
        In this case windows 7.
        It will look as win 10 when running on win 10 and so on.

        If you want to make other type of look, you can use stylesheets or make a completly new
        QStyle class for it. In any way, its a lot of work.

          Do you think it's because of the old-fashioned book I use (C++-GUI-Programming-with-Qt-4-2ndEdition) or the look is the basic and I will use the new ones when I get further in the book?

            Nope, its not related to the age of the book and it will look the same also later on.
            Its how widget application looks. unless you make your own style.
            It looks like all the other win 7 apps which is by design.

              What do you mean by that, please? do you mean I use some other classes for my app?
              What minor changes I can do to my app to look a little nicer?

              It looks like all the other win 7 apps which is by design.

              Hmm, but my prior app (Calculator) looks more graphical and resembles nowadays Wind 7/10 app!

                @tomy A Qt app usually looks like any other app on the system where it is executed. On Windows 7 it looks like Windows 7 applications, on Windows 10 it looks like a Windows 10 application. Not sure why you bother about this while reading the book.
                If you want your app to look differently then you can use stylesheets: http://doc.qt.io/qt-4.8/stylesheet-examples.html

                  • What minor changes I can do to my app to look a little nicer?
                    what would make it look nicer?
                    You can use other icons or colors but overall it will still look like the platform.

                    So the only solution is http://doc.qt.io/qt-4.8/stylesheet-examples.html although I don't know where in the app (the screen, buttons, tables etc), it changes and still needs a lot of work.

                    Okey. Thank you.
