If you want the button to close the window, use gtk_widget_destroy() and g_signal_connect_swapped() on the "clicked" signal, so that the window will be destroyed, and if it's the last window managed by the application, the application will quit. > gtk_main(); Don't nest a main loop in the activate signal handler; GApplication does all the main loop spinning for you. > int main(int argc, char **argv) > { > int status = 0; > GtkApplication *app; > app = gtk_application_new("quit.example", G_APPLICATION_FLAGS_NONE); > g_signal_connect(app, "activate", G_CALLBACK(activate), NULL); > status = g_application_run(G_APPLICATION(app), argc, argv); > g_object_unref(app); There's no real need to do this — the OS will collect the memory of your process at the end of it. It only helps if you're running under Valgrind, or similar tools.
