Settings #1

Provide global settings for all modules, accessible via core
also create an alternative to the currently implemented property concept using QSettings (is it really type safe?)

semaph0r commented 11 years ago

I think QSettings is not type-safe because it uses a simple key-value storage mechanism where <QString, QString> or <QString, QInt> will be stored.

As mentioned in the documentation, you will retrieve an QVariant object. And that's the point - this can be literally anything :(

Norman0406 commented 11 years ago

I would like to provide a type safe form of storing settings in files, that's why I implemented a custom settings concept which stores value as well as type informaton. However, I noticed QVariant does provide type checking using QVariant::type(). When implementing a custom storage format using QSettings::registerFormat, it might be possible to store type information as well and provide a type safe approach to writing settings to XML.
