Un GtkApplication mínimo. Use Xanela de aplicativo se quere compatibilidade con GMenu.
#include <gtk/gtk.h>
static void
activate (GtkApplication *app,
gpointer user_data)
{
GtkWidget *window;
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
gtk_window_set_application (GTK_WINDOW (window), GTK_APPLICATION (app));
gtk_window_set_title (GTK_WINDOW (window), "Hello GNOME");
gtk_widget_show_all (GTK_WIDGET (window));
}
int
main (int argc, char **argv)
{
GtkApplication *app;
int status;
app = gtk_application_new ("org.gtk.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);
return status;
}
Neste exemplo empregaremos o seguinte:
GtkApplication
GtkWindow
