+
+ This class is a helper used for wxFont creation using named parameter
+ idiom: it allows to specify various wxFont attributes using the chained
+ calls to its clearly named methods instead of passing them in the fixed
+ order to wxFont constructors.
+
+ For example, to create an italic font with the given face name and size you
+ could use:
+ @code
+ wxFont font(wxFontInfo(12).FaceName("Helvetica").Italic());
+ @endcode
+
+ Notice that all of the methods of this object return a reference to the
+ object itself, allowing the calls to them to be chained as in the example
+ above.
+
+ All methods taking boolean parameters can be used to turn the specified
+ font attribute on or off and turn it on by default.
