DrawPanel panel;

setLayout(new BorderLayout());
panel = new DrawPanel();
add("Center", panel);
}
public static void main(String args[]) {
Frame f = new Frame("DrawTest");
DrawTest drawTest = new DrawTest();
drawTest.init();
drawTest.start();
f.add("Center", drawTest);
f.setSize(800, 800);
f.show();
}
public String getAppletInfo() {
return "A simple drawing program.";
}
}
class DrawPanel extends Panel implements MouseListener, MouseMotionListener {
public DrawPanel(){
setBackground(Color.white);
addMouseMotionListener(this);
addMouseListener(this);
JButton button = new JButton("Quit");
button.addActionListener (new ActionListener () {
public void actionPerformed (ActionEvent e) {
System.exit (0);
}
} );
add(button);
}
