Java swing JoptionPane

我想用JavaSwing创建一个小游戏，我试图找到如何创建类似joptionpane的东西（将其放在ActionListener中），但要复杂一点。因此，到目前为止，当用户按下菜单中的选项时，将弹出一个joptionpane，用户将在其中选择玩家数量（2-4）。 之后，我希望这些用户给出一个名称，并从4种可用颜色中进行选择（绿色、蓝色、红色、黄色，如果有人选择蓝色，那么下一个用户将无法选择蓝色）。 因此，它必须包括一个地方，用户将写下他的名字和4个选项。 例如，如果有2名玩家，它应该只为2人获得文本和选择。任何暗示都会很有帮助。谢谢你抽出时间。 这是我的actionListener类代码（已编辑）： （编辑：目前我唯一想不出的是，当用户选择红色时，例如，蓝绿色和黄色将变成setEnabled（错误））

你最近还有一个尚未回答或投票的开放性问题，但你正在问一个新问题。你看到了吗？您应该使GUI代码面向创建JPanel。然后，您可以创建一个获取所有这些信息的JPanel，并将其放入JDialog中（就像您将JPanel放入JFrame中一样——这并不复杂），然后显示它。完成。他给了你基本上构建你自己的UI的构建块，用于捕获用户输入，这样你就可以在任何情况下重复使用它，这是我根据你的具体问题所建议的。

JOptionPane

允许指定一个

组件

作为消息，这使得API非常强大。这意味着您可以在

JPanel

之类的东西上设计基本UI，并将其作为消息参数提供给

JOptionPane

，作为
