just forgot to indicate the entry point. In order to open the setting browser: SystemSettingBrowser open. Cheers Alain Alain Plantec a écrit :
Hi all, I've changed the new setting implementation. The new proposition is attached. I think that this implementation is in sync with Lukas remarks; and yes, I think it is much better now, thanks! I also removed PragmaHandler and SettingHandler classes as Stephane suggested. It temporarily includes several (stupid) examples for testing purpose. Comments have not yet been changed. I will do it asap. Remarks, comments etc are welcome. Cheers Alain

- A setting with value is an instance of SettingValue or of one of its subclasses. Such a setting holds a useful global system parameter and is made persistent: it is stored in a class variable which is initialized by the method that declares the setting.
I think the problem with this proposal is that it mixes the model (the value of the setting) and the meta-model (the model of the setting). This is problematic because then all code depends on the settings package and when reading/writing settings application code must be aware of the indirection introduced through the setting.
Why isn't a setting simply a variable local to the package, and the setting-description a separate object (method) that can also be packaged separately? Lukas
