Removing the CENTER element from a JPanel using BorderLayout

问题

Is there any way of removing the Component added to the CENTER of a JPanel with a BorderLayout, without having to reference the Component itself?

回答1:

Something like this?

BorderLayout layout = (BorderLayout)panel.getLayout();
panel.remove(layout.getLayoutComponent(BorderLayout.CENTER));
