Hi,
hier mal ne Anwendung die beides ist, Applet & normale Anwendung:
| C++: |
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
public class Circles extends JApplet
{
private static class CirclesPanel extends JPanel
{
public CirclesPanel(int nC)
{
numCircles = nC;
}
private void kreis(Graphics g, int x, int y, int w, int n)
{
// System.out.println(x+ " " + y + " " + w + " " + n);
g.setColor(Color.red);
g.fillOval(x,y,w*2,w*2);
g.setColor(Color.black);
g.drawOval(x,y,w*2,w*2);
g.setColor(Color.black);
Font f = new Font("Helvetica",0,12);
g.setFont(f);
FontMetrics fm = getFontMetrics(f);
String s = new String(Integer.toString(n+1));
g.drawString(s,x+w - fm.stringWidth(s)/2, y+w + fm.getAscent()/2 - fm.getDescent()/2);
}
public void paint(Graphics g)
{
g.setColor(Color.green);
g.fillRect(0,0,getWidth(),getHeight());
for(int i = 0; i < numCircles; ++i)
{
int x = (int)(Math.random()*(getWidth()+1));
int y = (int)(Math.random()*(getHeight()+1));
int w = (int)(1+Math.random()*(getWidth()/10-1));
kreis(g, x-w, y-w, w, i);
}
}
private int numCircles;
}
public void init()
{
try
{

catch(Exception e)

return;
}

}
});
}
