BorderLayout and put the TextArea in its center. Then we create a Panel, set the LayoutManager of the Panel to FlowLayout, add the button to the panel, and then add the panel to the south part of the applet. Indeed that's exactly what was done to produce the above applet. Here's the code:
import java.applet.*;
import java.awt.*;
public class PanelExample extends Applet {
public void init() {
this.setLayout(new BorderLayout());
this.add("Center", new TextArea());
Panel p = new Panel();
p.setLayout(new FlowLayout(FlowLayout.CENTER));
p.add(new Button("OK"));
this.add("South", p);
}
}add(...) or this.add(...)) and adding to the panel (p.add(...) ).On the other hand it doesn't matter whether you add the panel to the applet and then add the button to the panel, or first add the button to the panel and then add the panel to the applet.
Another common use for a panel is to align a series of checkboxes in a GridLayout with one column.
