Catching the arrow keys

[jody <jody xha gmail com>]

Hi
In my Gtk::Window i have implemented my key event function

bool xbv::press_action(GdkEventKey *e) {
    switch (e->keyval) {
    case GDK_Left:
        printf("Left pressed\n");
        break;
    case GDK_Right:
        printf("Right pressed\n");
        break;
    case GDK_Up:
        printf("Up pressed\n");
        break;
    case GDK_Down:
        printf("Down pressed\n");
        break;
    case GDK_Escape:
        printf("Escape pressed\n");
        break;
}

But when my Window is running, only the Escape key is caught, but none
of the arrow keys.
Am i missing something, or isn't it possible?

Thank You
  Jody
