Why the Button's moving while editing text in a TextArea ?

public class Walker extends JApplet {
public void init() {
Container cp= getContentPane();
cp.setLayout(new BoxLayout(cp, BoxLayout.PAGE_AXIS));
cp.add(new JButton("Walker"));
cp.add(new JTextArea(10,10));
}
}

I have not used BoxLayout before,
but I suspect it is because..
"Similarly, for a vertical layout, BoxLayout
attempts to make all components in the column
as wide as the widest component. If that fails,
it aligns them horizontally according to their X
alignments."

As the JTextArea grows, the layout grows
and the JButton remains centered within it..

Have you considered using other layouts?

But, typing text in JTextArea does't change
its size, X alignment, does it?

I know I can stop it but was just testing the BoxLayout
and it came with something like that.

Because its not in a JScrollPane.

cp.add(new JScrollPane(new JTextArea(10,10)));
