You should probably create a custom DesktopManager . 您可能应该创建一个自定义DesktopManager 。 The DesktopManager is responsible for managing the desktop. DesktopManager负责管理桌面。 In particular you would want to extend the DefaultDesktopManager as it provides the current support for positioning the buttons of the minimized internal frames. 特别是，您将希望扩展DefaultDesktopManager，因为它为定位最小化内部框架的按钮提供了当前支持。

In particular I would think you need to override the getBoundsForIconOf(...) method and probably the getPreviousBounds(...) . 特别是，我认为您需要重写getBoundsForIconOf(...)方法，并且可能重写getPreviousBounds(...) 。 You could look at the source code to see how it works for the horizontal layout and modify the code for your vertical layout. 您可以查看源代码，以了解水平布局的工作原理，并修改垂直布局的代码。

This posting has a little example to get you started: //stackoverflow.com/questions/18433475/jdesktoppane-minimising-jinternalframes. 这篇文章有一个入门的小例子：//stackoverflow.com/questions/18433475/jdesktoppane-minimising-jinternalframes。 Normally when you maximize an internal frame it will cover any iconified buttons. 通常，当您最大化内部框架时，它将覆盖所有图标化的按钮。 The custom code will only maximize the internal frame to the top of the iconified buttons. 自定义代码只会将内部框架最大化到图标化按钮的顶部。
