CardLayout - 如何更改组件名称

Question

有没有办法更改添加到CardLayout面板的面板名称？我想使用show方法，而不必使用我将面板添加到主面板时给出的面板名称。

JPanel panel = new JPanel();
add(panel, "0");
show(this, "0");
...              // I change name of the panel to "1"
show(this, "1"); // now I can do this to show panel

Answer 1

    // original cardPanel1 name is "card1"

    CardLayout lay = (CardLayout)parentPanel.getLayout();
    lay.removeLayoutComponent(cardPanel1);
    lay.addLayoutComponent(cardPanel1, "card4");

    // cardPanel1 can now be shown using "card4" name
