/** \class Fl_Mac_App_Menu
|
|
Mac OS-specific class allowing to localize the application menu.
|
|
|
|
These character strings are used to build the application menu. They can be localized
|
|
at run time to any UTF-8 text by placing instructions such as this \e very
|
|
early in the program:
|
|
\verbatim
|
|
Fl_Mac_App_Menu::print = "Imprimer la fenêtre";
