Hiding my program in the System Tray in Windows
提问by Adam Smith
I'd like my program to display an icon in the TaskBar Status Area near the clock in Windows and found a way to do so.
我希望我的程序在 Windows 时钟附近的任务栏状态区域中显示一个图标，并找到了一种方法。
The thing is, I'd like my program to stay open in the Status Area if the "X" is pressed on the window, but not in the System Tray, but I have no idea how to do so and searching on Google didn't help (I'm probably not searching the right terms).
问题是，如果在窗口上按下“X”而不是在系统托盘中，我希望我的程序在状态区域中保持打开状态，但我不知道如何这样做并且在 Google 上搜索没有t帮助（我可能没有搜索正确的术语）。
Edit:I think I used the wrong terms. I know how to have my program's icon in the notification area, what I'd like is to hide it in the area where it is normally displayed when you minimize a window.
编辑：我想我使用了错误的术语。我知道如何在通知区域中显示我的程序图标，我想要的是将它隐藏在最小化窗口时通常显示的区域中。

Then don't use the system tray.
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域中保持打开状态，

I guess you want the taskbar button to be removed when you minimise the main form. You achieve this by petting its visible property to false, however you do that with your Java framework.
我猜您希望在最小化主窗体时删除任务栏按钮。您可以通过将其可见属性设置为 false 来实现这一点，但是您可以使用 Java 框架来实现这一点。
