+
+ Note that wxAppTraits is an abstract class since it contains many
+ pure virtual functions.
+ In fact, by default, wxWidgets creates a @c wxConsoleAppTraits object for
+ console applications (i.e. those applications linked against wxBase library
+ only - see the @ref page_libs page) and a @c wxGUIAppTraits object for GUI
applications.
+ Both these classes are derived by wxAppTraits and represent concrete
+ implementation of the wxAppTraits interface.
