How to edit a .ini file?

[Sriu1]

@JonB 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
and why is this getting created
[General]
background-image=myImage.png

I want to edit here
[shell]
background-image=/home/tel/Documents/woman.jpg

Can you please send a code snippet?

[JonB]

@Sriu1
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 pointing out that QSettings does not handle those lines in the way Windows/your "weston" does. Which may lead to problems.

@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();

@Sriu1
Since I specifically wrote: If you use shell/background-image, you must remove the beginGroup(). You ignored that and left it in? Please don't.

@JonB Hi,
I tried this code

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

@Sriu1 Looks like it is working now?

[Sriu1]

but .ini is getting altered.The "#" starting lines are getting removed.

[JonB]

@Sriu1
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.

@JonB Hi Thanks,
The ini is weston generated.How to handle the # lines in it ?If I give the ini without # lines my application is not working.Please suggest

[JonB]

@Sriu1
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.
