2 个解决方案

First you should forget immediately and forever about existence of drag-and-drop visual tools that generate UI in java. 首先，您应该立即永久忘记使用Java生成UI的拖放可视化工具的存在。 These tools generate code that cannot be changed. 这些工具生成的代码无法更改。 You have to be an expert in java UI to make even minor changes in such code. 您必须是Java UI的专家，才能对此类代码进行微小的更改。

Second, google "java ui programming". 其次，谷歌“ java ui编程”。 This is what I did for you. 这就是我为你做的。 Here are some links I can recommend. 我可以推荐一些链接。
