使用Eclipse WindowBuilder创建一个GUI

Question

我想为我创建的游戏创建一个GUI，最初这个游戏是基于控制台的，但是我试图提高我的技能并添加一个GUI。

我已经成功地添加一个按钮，并添加一个事件处理程序，以便在单击按钮时，代码将运行，但是，我不知道......

由于基于控制台的，在我的游戏以前我会将我的主要方法中的所有代码粘贴到GUI部分，然后如何让它将我用于文本框的文本打印出来，然后如何让它显示按钮（在这种情况下，攻击，防守或逃跑）。

我也想知道如何让代码等待用户点击其中一个按钮，然后当按钮被点击时我该如何运行代码。

这是我在我的主要方法中的代码。这很长。

我建议先阅读关于java swing的更多内容，甚至可以在youtube上观看并完成教程。你的问题：

问题：我也想知道如何让代码等待用户点击其中一个按钮，然后当按钮被点击时我该如何运行代码。

回答：那么当你运行GUI代码时，它不会持续运行，它会等待并“监听”用户的输入。当你点击这个按钮时，动作“监听者”或者你已经实现的监听者将运行你想要在按钮单击上运行的代码。

问题：由于我的游戏之前是基于控制台的，我将我的主要方法中的所有代码粘贴到GUI部件的哪个位置，然后如何让它将我用于文本框的文本打印出图形用户界面，那么我将如何显示按钮（在这种情况下，攻击，保卫或逃离）。

答：GUI是一个巨大的领域，并找出如何你想你的窗口看，在哪里以及如何文本将被打印检查了这一点：

这些按钮可以随时使用JButton，你仍然可以使用从键​​盘输入的1,2,3,4，至于在这种情况下如何按下Attack，Defend或Flee。

关于windowsbuilder的另外一件事情就是您的情况，因为您已经在控制台上创建了程序并且想要将它转换为GUI，所以如果您不需要，它可能会更容易，更快速，更有学问值得使用windowbuilder。手动做。
