alphabetize

[pastarmovj, 2011/09/29 15:15:03]

Done. Sorry about that I went for the logical order instead of the alphabetical
one.

Not only the comment is outdated the whole function is not there anymore :)

shouldn't this rather return bool? Then again, if it's the same as GetPref() why
do we have both?

Why is there both Get() and GetPref()?

[pastarmovj, 2011/09/29 15:15:03]

Get is what UI used to get Pref Dictionaries whapped around a copy of the Value
whereas GetPref only returns a const pointer to the original data. Now Get is
gone and moved to where it belongs the UI level.
