Luc,

  public Component getCurrentCard(Container parent) {    
    if (!parent.getLayout() instanceof CardLayout) {
      throw new IllegalArgumentException("parent has no CardLayout");
    }
    int count = parent.getComponentCount();
    for (int i = 0; i < count; i++) {
      Component comp = parent.getComponent(i);
      if (comp.isVisible()) return comp;
    }
    return null;
  }
