How to edit a .ini file?
-
@Sriu1
OK, I think I might guess what you mean (not sure if you've changed code since original?). Do you mean: after you have gonesettings.setValue("background-image","myImage.png");you want that value saved back to the.inifile, 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
%23is the hex code for a#, andQSettingsis choosing to save it encoded. You seem to be using#in your.inifile as a comment character. What makes you think that is acceptable toQSettings? -

I don't know exactly why yoursettings.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 useshell/background-imageinstead. - Does it work now?
If still not, you can ask with a minimal example, consisting now of just a couple of lines in the
.inifile, 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.

QSettingsdoes not handle those lines in the way Windows/your "weston" does. Which may lead to problems. - Take out all the the

@JonB Hi,Thanks for the reply
I tried this as you mentioned.
QSettings settings("/home/tel/weston.ini", QSettings::IniFormat);
settings.beginGroup("shell");
settings.setValue("shell/background-image","myImage.png");
settings.sync();
settings.endGroup();My ini file after executing_________________

So if your.inifile is not acceptable wrt the#s after you have modified it viaQSettings(which does not necessarily claim to be compatible with existing.inifile 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
QSettingsas the reader, but not the writer. Do your own writing instead. - Allow
QSettingsto write back. When finished, read the.inifile back as a text file and do your own substitution of%23s back to#s as you write it out as a text file.
- Do not use
