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!

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

Thank you in advance.

Each GUI component can be contained only once. If a component is already in a container and you try to add it to another container, the component will be removed from the first container and then added to the second.
