Java框架图标化问题

Question

我试图找出如何修改一些现有代码，以便启动的控制台窗口最小化为托盘图标，而不是仅打开窗口的默认行为。不幸的是，我不懂 Java，所以我只能搜索 Google，猜测并检查哪些代码对我来说有意义。我知道这要求很高。我正在尽力慢慢学习 Java，我非常感谢您的帮助。有人可以阅读这个文件并告诉我是否需要进行明显的 boolean 翻转来改变这种行为，或者交换一些事件处理程序。代码已经提供了在托盘图标和完整窗口之间来回切换的功能，并且我通过阅读窗口监听器(特别是 windowIconified)取得了一些进展，但我还没有足够的经验来真正理解我所做的更改因为它们并不是立即显而易见的。下面的文件是这个项目中的许多文件之一，所以如果读完后你觉得我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窗口的文件，所以我假设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。
