Hi Everyone!
I have a problem with the folowing code:
As the program it is like this, it automatically draws(load) objects while it runs. This is what I do not want, I want it load each object (drawing ) when I clicked Generate PacketButton from second this class. I mean this button should call a method from second class.
package rainbowservice;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import com.borland.jbcl.layout.*;
import javax.swing.border.*;

public class Area2 extends JFrame {
JPanel contentPane;
Nodes nodes1 = new Nodes();
Hosts h = new Hosts();
XYLayout xYLayout1 = new XYLayout();
JPanel jPanelControl = new JPanel();
XYLayout xYLayout2 = new XYLayout();
Border border1;
TitledBorder titledBorder1;
static Button GPackets = new Button();
//Construct the frame
public Area2() {
enableEvents(AWTEvent.WINDOW_EVENT_MASK);
try {
jbInit();
}
catch(Exception e) {
e.printStackTrace();
}
}
//Component initialization
private void jbInit() throws Exception {
contentPane = (JPanel) this.getContentPane();
border1 = new EtchedBorder(EtchedBorder.RAISED,Color.red,Color.blue);
titledBorder1 = new TitledBorder(border1,"Control_Panel");
contentPane.setLayout(xYLayout1);
this.setSize(new Dimension(789, 488));
this.setTitle("Simulation of Resource Resavation from Rainbow Service Architecture ");
jPanelControl.setLayout(xYLayout2);
jPanelControl.setBorder(titledBorder1);
GPackets.setLabel("Generate_Packet");
GPackets.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(ActionEvent e) {
GPackets_actionPerformed(e);
}
});
contentPane.add(nodes1, new XYConstraints(170, 4, 613, 323));
contentPane.add(jPanelControl, new XYConstraints(2, 4, 167, 323));
jPanelControl.add(GPackets, new XYConstraints(4, 6, 110, 24));
}
//Overridden so we can exit when window is closed
protected void processWindowEvent(WindowEvent e) {
super.processWindowEvent(e);
if (e.getID() == WindowEvent.WINDOW_CLOSING) {
System.exit(0);
}
}
void GPackets_actionPerformed(ActionEvent e) {
??? ???
}
}

//// The next following class draws rectangles and I want it draw them on request from the action event of:
void GPackets_actionPerformed(ActionEvent e) {
}
of the above program
package rainbowservice;
import java.awt.*;
import java.awt.Graphics2D;
import java.awt.*;
import java.awt.Point;
import java.awt.GradientPaint;
import javax.swing.Timer;

public class Hosts
{
static int mx;
static int my;
private String fhostName, shostName;
private int bufferSize;
private int numberOfPackets;
private int interfaces;
static int pWidth, pHeight;
static int bWidth, bHeight;
public Hosts()
{
fhostName = "Host 1";
shostName = "Host 2";
bufferSize = 50;
numberOfPackets = 5;
interfaces = 2;
pWidth = 10;
pHeight =10;
bWidth = 55;
bHeight = 20;
mx =5;
my =10;
}
public void drawSelfHost1( Graphics2D g,int x, int y)
{
mx = x;
my = y;
g.setPaint(Color.blue);
g.setStroke(new BasicStroke(3.0f));
g.drawRect(mx,my,80,60);

}
public void drawSelfHost2( Graphics2D g,int x, int y)
{
mx = x;
my = y;
g.setPaint(Color.blue);
g.setStroke(new BasicStroke(3.0f));
g.drawRect(mx,my,80,60);
}
public void drawBuffer(Graphics2D g,int x, int y)
{
mx = x;
my = y;
g.setPaint(Color.black);
g.setStroke(new BasicStroke(3.0f));
g.drawRect(mx,my,bWidth,bHeight);
}
public void Packet(Graphics2D g,int x, int y)
{
mx = x;
my = y;
g.setPaint(Color.red);
g.drawRect(mx,my, pWidth, pHeight);
}

}
This third class is responsible for setting the location of object to be drawn
package rainbowservice;
import javax.swing.JPanel;
import javax.swing.JPanel;
import java.awt.*;
import javax.swing.Timer;
import java.lang.Thread;
import java.util.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;

public class Nodes extends JPanel implements ActionListener {
private Timer tm;
private Hosts hs;

static int x, y,x1,y1;
public Nodes( ) {
hs = new Hosts();
x = 5;
y = 7;
this.setBackground(Color.yellow);
}
protected void paintComponent(Graphics g)
{
super.paintComponent(g);
Graphics2D g2 =(Graphics2D)g;
drawAllStations(g2);
}
//DRAW ALL HOSTS
public void drawAllStations(Graphics2D g)
{
//Host One on the left
hs.drawSelfHost1(g,80,60);
//Draw Buffer for Host 1
hs.drawBuffer(g,x+90,y+70);
// Host One on the Right
hs.Packet(g,x+127,y+77);
//Host Two on the Right
hs.drawSelfHost2(g,520,60);
}
public void actionPerformed(ActionEvent e)
{
GCR();
}
public void GCR(){
if(x == 198 )
{
tm.stop();
}

else
repaint();
}
}
