Question

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.

From: http://download.oracle.com/javase/tutorial/uiswing/components/toplevel.html:

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.
