Re: cherche exemple de code GtkMM4 (C++) pour ajouter des options à une application GtkMM-4 graphique (libre) add_main_option_entry

[Lamourec Alain]

Bonsoir

Sur cet exemple, j'ai plutôt Gio::Application::OPTION_TYPE_BOOL et
Gio::Application::OPTION_TYPE_STRING :
https://student.cs.uwaterloo.ca/~cs246/common/gtkmm/gtkmm-examples-3.0/09-commandLine/ex2/exampleapplication.cc
