使用 Eclipse WindowBuilder 创建 GUI

Creating a GUI with Eclipse WindowBuilder

我正在尝试为我创建的游戏制作 GUI,最初这款游戏是基于控制台的,但我正在努力提高我的技能并添加 GUI。

我已经设法添加了一个按钮并添加了一个事件处理程序,因此当单击该按钮时,代码将 运行,但是,我想知道...

由于我的游戏之前是基于控制台的,我应该将 Main Method 中的所有代码粘贴到 GUI 部分的什么位置,然后我如何让它打印出我在 GUI 中的文本框中使用的文本,那么我将如何显示按钮(在本例中为攻击、防御或逃跑)。

我也想知道如何让代码等待用户单击其中一个按钮,然后在单击该按钮时如何让代码 运行。

这是我的主要方法中的代码。好长。

我建议首先阅读更多关于 java 挥杆的内容,甚至在 youtube 上观看并完成教程。您的问题:

问题:我还想知道如何让代码等待用户单击其中一个按钮,然后如何在单击该按钮时让代码 运行。

回答:当您 运行 GUI 代码时,它不会 运行 连续,它会等待 "listens" 用户的输入。当您单击此按钮时,操作 "listener" 或您实施的任何侦听器将 运行 您想要在按钮单击时 运行 的代码。

问题:由于我的游戏之前是基于控制台的,所以我应该将 Main Method 中的所有代码粘贴到 GUI 部分的什么位置,然后如何让它打印出我在 Textbox 中使用的文本GUI,那么我如何让它显示按钮(在本例中为攻击、防御或逃跑)。

答案:GUI 是一个很大的领域,要弄清楚您希望 window 的外观、打印文本的位置和方式,请查看:

http://da2i.univ-lille1.fr/doc/tutorial-java/ui/features/components.html

对于这些按钮,您始终可以使用 JButton,并且您仍然可以使用从键​​盘输入的 1、2、3、4,至于在这种情况下您将如何按下,Attack、Defend 或 Flee。

关于 windowsbuilder 的另一件事是,在你的情况下,因为你已经在控制台上制作了程序并且你想将它转换成 GUI,它可能更容易,更快并且更值得学习如果您 不使用 windowbuilder。手动完成。
