Saving dial value

hi
the akey is the name of the value. It saves to registry so that why it needs a name
For you , it could be slidervalue or something that explains what u save.

You can use anything u like for company. Its also because its store in registry.
So just use some name u like that IS not a real company. :)

For loading i use;

 QSettings settings("settingName");
    int  aValue=settings.value("aKey").toInt();
    int  aValue2=settings.value("aKey2").toInt();
    ui->dial->setValue(aValue);
    ui->dial_2->setValue(aValue2);

and for saving i use

QSettings settings("settingName");
    int somevalue = ui->dial->value();
    int somevalue2 = ui->dial_2->value();
    settings.setValue("aKey",somevalue);
    settings.setValue("aKey2",somevalue2);

These work for me , thanks for help. by the way, in a debian OS , where do it save ( in which directory)?

Hi
That is good question :)
try
qDebug() << settings.fileName();

If I may suggest one improvement is to use a better name than
"aKey" and "aKey2"
Maybe Dial1Value and Dial2Value

when i click the close button, while it is saving data , it waits sometime and close with a 1-2 seconds delay. Is this normal ?

@rapid84
Normally it saves really fast so i never noticed it.

on raspbian sometimes it takes up to 5 -6 seconds to store the data. i have tested it, maybe i will need to use QFile.

@rapid84
ok. thats pretty long.
It must have a reason.
QFile should be faster.

Hi,

You shouldn't need to but you can try adding a call to sync in order to flush the content of your settings to the disk.
