Java UI Generator导致大量延迟?

标签: java eclipse performance swing netbeans

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
