    @Sriu1
    But the code you show, do not change background-image ?
    OR what is the actual issue currently or what you need help with ?

      Hi @mrjj @JonB @SGaist ,
      This is my code where I'm trying to edit only background-image=/home/tel/Documents/woman.jpg

      QSettings settings("/home/tel/weston.ini", QSettings::IniFormat);
      settings.beginGroup("shell");
      settings.setValue("background-image","myImage.png");
      settings.endGroup();

      This is my weston.ini before running the code.

      Please suggest why is it altering the complete ini file.

        OK, I think I might guess what you mean (not sure if you've changed code since original?). Do you mean: after you have gone settings.setValue("background-image","myImage.png"); you want that value saved back to the .ini file, and you're not seeing that happen? Then see http://doc.qt.io/qt-5/qsettings.html#isWritable, http://doc.qt.io/qt-5/qsettings.html#sync.

        EDIT: Oh, now you're changing the question/information ... It's much better if you can do that in the first place...

        I can only say %23 is the hex code for a #, and QSettings is choosing to save it encoded. You seem to be using # in your .ini file as a comment character. What makes you think that is acceptable to QSettings?

            I don't know exactly why your settings.beginGroup("shell"); is not being taken into account. It's going into General because of:

            In addition, if you save a top-level setting (a key with no slashes in it, e.g., "someKey"), it will appear in the INI file's "General" section.

            So, if it were me, I would try for myself:

            • Take out all the the # lines, at least temporarily while I test.
            • Now try again with beginGroup(). Does it work now?
            • If that doesn't work, try without beginGroup() and use shell/background-image instead.
            • Does it work now?

            If still not, you can ask with a minimal example, consisting now of just a couple of lines in the .ini file, instead of loads of irrelevant stuff.

            I'm not creating any comments.That is the ini file generated by weston.The" # "are not created by me.
            I'm just editing it

            I'm pointing out that QSettings does not handle those lines in the way Windows/your "weston" does. Which may lead to problems.

                    QSettings settings("/home/tel/weston.ini", QSettings::IniFormat);
                    settings.setValue("shell/background-image","myImage.png");
                    //settings.sync();

                    @Sriu1 Looks like it is working now?

                        Yes, as I said earlier:

                        I can only say %23 is the hex code for a #, and QSettings is choosing to save it encoded. You seem to be using # in your .ini file as a comment character. What makes you think that is acceptable to QSettings?

                        and

                        I'm not creating any comments.That is the ini file generated by weston.The" # "are not created by me.
                        I'm just editing it

                        I'm pointing out that QSettings does not handle those lines in the way Windows/your "weston" does. Which may lead to problems.

                            So if your .ini file is not acceptable wrt the #s after you have modified it via QSettings (which does not necessarily claim to be compatible with existing .ini file formats from what I can see, only compatible with its own reading & writing), and you or someone else cannot find a call to make it compatible, you seem to have 3 choices:

                            • Do not use QSettings. Write your own reader/writer.
                            • Use QSettings as the reader, but not the writer. Do your own writing instead.
                            • Allow QSettings to write back. When finished, read the .ini file back as a text file and do your own substitution of %23s back to #s as you write it out as a text file.
