I'm trying to write an embellishment class (ala "Design Patterns") to draw a
border around a Component. Here is my code:
---------
import java.lang.*;
import java.awt.*;
import java.applet.Applet;
public class Foo extends Applet {
public void init() {
setLayout(new BorderLayout());
add("Center", new Border(new Button("Center")));
}
}
class Border extends Panel {
Border(Component c) {
setLayout(new BorderLayout());
add("Center", c);
}
public void paint(Graphics g) {
Dimension d = size();
setForeground(Color.red);
g.fillRect(0, 0, d.width-1, d.height-1);
}
}
--------------------------------------
Note: I've hand typed this example in and I may have added some syntax errors,
but the original compiles and runs.
When the applet runs the button "Center" appears and works, the red rectangle
is never drawn. I've added print statements and discovered that Border's paint
method is never called. Why?
Thanks,
C Helck chris@tkna.com
