将我的程序隐藏在Windows中的系统托盘中

标签: java windows swing system-tray

我希望我的程序在Windows中靠近时钟的TaskBar状态区域中显示一个图标,并找到了一种方法。

问题是,我希望我的程序在状态区域保持打开状态,如果在窗口上按下“X”,但不在系统托盘中,但我不知道如何这样做并搜索谷歌没有帮助(我可能没有找到合适的条款)。

编辑:我认为我使用了错误的条款。我知道如何在通知区域中显示我的程序图标,我想要的是在最小化窗口时将其隐藏在通常显示的区域。

我知道如何在通知区域中显示我的程序图标,我想要的是在最小化窗口时将其隐藏在通常显示的区域。

然后不要使用系统托盘。

  

问题是,如果在窗口上按下“X”,我希望我的程序在状态区保持打开状态,

frame.setDefaultCloseOperation(JFrame.HIDE_ON_CLOSE);

JavaSE v 6中添加了系统托盘支持。

我想你希望在最小化主窗体时删除任务栏按钮。您可以通过将其visible属性设置为false来实现此目的,但是您可以使用Java框架执行此操作。
