Java UI Generator导致大量延迟？
我在Java GUI上很糟糕，并使用生成器为我制作了大部分GUI。我在Netbeans中创建它，然后将其复制到Eclipse。它在启动时大约停留了我相当强大的计算机大约5秒钟，虽然我已经尝试过计时和东西，但我无法弄清楚原因。我不喜欢责怪发电机，但它100％来自该UI代码。
我真的很感谢有人帮助我找出导致它的原因，并且通常会改善丑陋的UI代码。其他代码未完成，这只是界面部分。
请注意，您可以删除我的所有代码，甚至是gridLayout，它仍会滞后，如果我将其编译为.jar并使用-classpath参数编译它具有相同的延迟

如果滞后是在WindowBuilder打开设计页面（解析）期间，则滞后是正常的。
