构建swing UI以实现方法编辑器

我正在构建各种方法编辑器。

方法（ MethodModel类）通常具有以下元素 –

1. List inputVariableNames
2. String resultVariableName

现在我有一个MethodModel类，它有上述字段作为其成员。 我还有一个MethodModelContainer类，它包含MethodModelContainer的列表（LinkedList，被调用的方法的顺序很重要）， MethodModel是当前文件/类中所有MethodModel的集合。

我试图构建一个swing用户界面，用户可以使用UI编辑一个方法（或编辑一个MethodModel对象）。 我计划通过为每个MacroModel类提供三个按钮来实现这一点，每个按钮用于“向上”和“向下”箭头以向下移动方法调用或向上移动LinkedList，第三个按钮用于打开用户的对话框可以编辑此特定MethodModel对象的成员。
我曾想过在MethodModelContainer的基础上有一个JTable行，其中每行有1个包含3个按钮的单元用于上述用途，每行代表一个MethodModel对象。
现在，只要更新MethodModelContainer，Jtable就需要自我更新。
我已经阅读了一些关于如何将JButtons / Jpanel添加到JTable的示例，并且所有这些示例都涉及编写自定义的单元格渲染器/单元格编辑器，这些东西我还没有找到合适的读物来理解。

关于如何使用Jtable或其他方式实现我的用例的任何指示都会有所帮助。

Answer 1

• List inputVariableNames

• with rows where each row would have 1 cell containing 3 buttons

然后myabe这样你可以…，我不是说这是唯一的方法，你可以将每个JComponents放入JTable中的单独Cell
