Subject: Introduce a Bool typedef for boolean return values
X-Git-Tag: upstream/5.2.1~669^2~659^2~962
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7efad31f6739b5a9284b17493516c404006372fa;p=platform%2Fupstream%2Fqtdeclarative.git

Introduce a Bool typedef for boolean return values

This helps in the interpretation of the type returned
by a method. It also makes it easier to later on change
the type back to a real bool if it makes sense. Bool
is currently typedef'ed to uint.
