You have to both allow the events, and set up a handler for the keypress
event, something like:
da = gtk_drawing_area_new ();
/* some code to place da */
/* Connect your callback to the signal */
gtk_signal_connect (GTK_OBJECT (da), "key_press_event",
(GtkSignalFunc) keypress_callback, NULL);
/* Unmask the signal */
/* You'll probably want to or this with the other events you want,
* typically you should grab the GDK_EXPOSURE_MASK as well for a drawing
* area */
gtk_widget_set_events (da, GDK_KEY_PRESS_MASK | GDK_EXPOSURE_MASK);
gtk_widget_show (da);
Then, you define your callback like:
gint entry_callback (GtkWidget *w, GdkEventKey *event, gpointer data)
{
g_print ("-I- Key Press %s\n", event->string);
}
