Java 框架图标化问题

Question

我正在尝试弄清楚如何修改一些现有代码，以便启动的控制台 window 开始时最小化为托盘图标，而不是仅打开 [=20] 的默认行为=].不幸的是我不知道 Java，所以我只需要搜索 Google 并根据对我有意义的代码进行猜测和检查。我知道这要求很多。我正在尽最大努力慢慢获取 Java，非常感谢您的帮助。有人可以阅读此文件并告诉我是否需要进行明显的布尔翻转来更改此行为，或者换出一些事件处理程序。代码已经提供了在托盘图标和完整 window 之间来回切换的规定，我通过阅读 window 听众，特别是 windowIconified 取得了一些进展，但我只是不我还没有足够的经验来真正理解我正在做的改变，因为它们不是很明显。下面的文件是该项目中的许多文件之一，因此如果您在阅读后觉得我弄错了并且缺少适用的代码，我可以提供它。如果我正确理解了代码，那么这是构建控制台 window 的文件，因此我认为需要在此处进行更改。感谢您的帮助！

Answer 1

starts out minimized as a tray icon

您需要使用：

setExtendedState(JFrame.ICONIFIED);

当您设置其他框架属性时。
