Re: Qsetting with property

an enum is a limitation of an int value (read about it online).
QSettings stores QVariant values, which could be an int value.

My guess would be that you currently store a string (QString) in the settings, try to store an int value (that is valid for FontSize).

please mark posts as solved if you found a solution.

Re: Qsetting with property

fontSize is enumeration accept either enum type  like FontSize.XXSmall etc as mentioned in the below link




However you can refer to the enum types using their integer value 70 , 120 etc. thus casting the string returned from getValueFor method will solve the issue. but make sure you use the correct enum type int value everytime storing to the QSetting/FontSize element.


fontSize: parseInt(app.getValueFor("FontSize", FontSize.Default))
