Question

I have a two JPanel s: a1 and a2 . a11 is sub panel of a1 . I want move a11 to a2 . How to do this?

Answer 1

Try this:

a2.add(a11); // move a11 from a1 to a2
a2.revalidate(); // apply changes in a2 layout
a1.revalidate(); // apply changes in a1 layout
a2.repaint(); // repaint a2 you to be able to see the changes
a1.repaint(); // repaint a1 you to be able to see the changes

Answer 2

you can do that by first remove a11 from a1 and then adding it to a2.

as follows,

a1.remove(a11);
a2.add(a11);
a2.repaint();
