java - netbeans 生成的代码中生成错误

到处寻找后，没有人遇到同样的问题。我需要编辑 netbeans 生成的代码，因为当我在设计 View 中删除一些 Swing 组件时，一个错误导致变量声明被删除，但在使用这些组件的 initComponents() 中，仍然存在抛出错误并且不允许我运行程序，代码如下:

我如何编辑生成的代码？

Answer 1

如果问题仍然存在，您必须在任何文本编辑器中打开 JFrame 类:记事本、Notepad++、写字板等，然后删除错误。然后返回 netbeans 并重新加载您的项目。

要删除表单项，请使用导航器窗口 (Ctl+7) 并安全地删除它们。
