(这类似于家庭作业问题。)
我最近在Scenebuilder中创建了一个示例UI,后来我不得不使用Java Swing编程。或多或少有效。现在这是我的任务,不是为了实际开发程序,而是为了在我的职业培训中学习一些东西,用Scenebuilder创建一个类似的用户界面,但这次实际上是一个工作。规格如下:
如果我可以启用编辑,则使复选框充当收音机框应该很容易。我发现很多例子几乎都符合我的要求,但仍然不能真正适用于我的情况。以下是其中一些:
public ObservableValue<Boolean> getCompleted()
方法,Eclipse提出了一些魔术,然后我在下面的相应代码中看到了你所看到的内容(没有控制台打印)。我的问题:我怎样才能使复选框对点击做出反应? React可能意味着在控制台上输出内容,我不需要给定的代码让它自动禁用其他复选框,我想自己想出那个部分。
我的代码:

我找到了解决方案。由于我改变了很多(我在提出这个问题后努力让这个愚蠢的事情工作了将近20个小时),所以列举我所做的所有改变并不是真的有用。但这至少是一个有效的例子 很少有线路负责制作男性&#34;和女性&#34;框触发彼此的对立面(这是我的任务特定的),其他一切只是为了实际正常工作CheckBoxTableCells。人们会认为这是一个非常常见的情况,并且应该有标准方法,例如&#34;将文本打印到控制台&#34;或者&#34;读取文件&#34;,但显然不是,显然在用UI编程时一切都必须复杂。
无论如何,咆哮,这是工作代码:
