Copying JPanel components

Show all headers | View raw

  To: comp.lang.java.gui
I want to copy the contents of a jPanel to another JPanel, then I want
to empty the original JPanel.
I unsuccessfully tried the following:

jPanel1 = new JPanel();
jPanel1.setBounds(371, 112, 364, 28);
jPanel1.add(new JLabel("a"));
jPanel1.add(new JLabel("b"));
jPanel1.add(new JLabel("c"));

JPanel jp = new JPanel();

int numComponents = jPanel1.getComponentCount();
System.out.println("Number of components in jPanel1 is " +
numComponents);

for (int i=0; i<numComponents; i++)
{
    jp.add(jPanel1.getComponent(i));
}
jPanel1.removeAll();

But I get an error like this
java.lang.ArrayIndexOutOfBoundsException: No such child: 2
	at java.awt.Container.getComponent(Unknown Source)...

NOTE:
If I replace the row inside the loop with the following row:
System.out.println(jPanel1.getComponent(i).toString());

then I dont get an exception in getComponent, I then get a correct
standard out to the console!

So how can I achieve copying JPanel components? Am I way off?
