不能将Swing组件添加到多个容器中？ [英] Can't a Swing component be added to multiple containers?

问题描述

我正在尝试（测试其他内容）将一个 JButton 引用添加到两个 JPanels 中进行测试，它从添加到的第一个面板中消失了！

I'm trying (testing something else) to add one JButton reference into two JPanels to test it, and it disappears from the first panel it was added to!

那么，不能将Swing组件添加到多个容器中吗？

So, can't a Swing component be added to multiple containers?
