J'essaie de mettre une bordure autour d'une gtk_hbox. Mon IHM est divisée en 2 parties : une drawing aera en haut et en bas, une gtk_hbox composée de 6 labels. J'aimerais ajouter une bordure autour de la gtk_hbox. J'ai vu qu'il fallait inclure cette hbox dnas une gtk_frame et ajouter cette frame à la main_window. Mais ceci ne marche pas :

voici le bout de code en question ( voir en gras ce que j'ai tenté de faire ) :

Quelqu'un pourrait me dire ce qui ne va pas ?

si c'est bien une bordure que tu veux, tu peux régler la marge entre la fenêtre et les widgets

Code :

GtkWidget *win = gtk_window_new(GTK_WINDOW_TOPLEVEL);
/***/
g_object_set (win, "margin", 30, NULL);

Depuis GTK 3, tu as gtk_widget_set_margin_[top|bottom|left|right]. Mais tu ne nous dis pas quelle version tu utilises...
