Voilà, c'et le 'main.c' du programme nommé PlanLibre. Regarde les deux "callbacks" obligatoires pour activer correctement la g_application (voir dans le bloc de fonction
main {} ) Et je vois que je laisse encore traîner une déclaration gtk_application que je sécurise par une macro G_APPLICATION.
Excuse : pas touché au programme depuis août.
Mais ce qui compte ce sont les
callbacks vers
startiup et
activate qui sont
obligatoires dans une g_application.
Data_app est propre à mon programme, ne pas en tenir compte.
Tu peux voir également comment j'accède aux fichiers d'interface faits avec Glade en regardant comment lje teste et charge l'interface principale "main.ui" çà peut toujours aider.
Autre "truc" à connaître : le blocage ou non de l'application à une seule
instance ou autoriser des instances multiples ; dans mon cas
j'interdis les instances multiples (le programme utilise des
timers c'est trop dangereux). C'est le test suivant :
/* test for uniqueness */
Bon courage !
