Graphics object in JComboBox

Thats cool....when I modified the code with your ideas

it compiled....but the only way I know to test it is

to put it in an applet such as:

(unfortunately this didnt compile, it wouldn't let me

declare a CustomComboBoxDemo object, and it

didnt like my use of the getValue method I threw

into CustomComboBoxDemo)

import java.awt.*;

import java.applet.*;

import java.util.*;

import java.lang.String;

import java.awt.event.*;

public class newColorChoose extends java.applet.Applet implements ItemListener {

Button colorButton = new Button();

String mycolor;

CustomComboBoxDemo myCombobox = new CustomComboBoxDemo();

public void init() {

this.setLayout(null);

myCombobox.setBounds(0,0,140,24);

colorButton.setBounds(140,0,210,24);

add(myCombobox);

add(colorButton);

colorButton.setBackground(Color.white);

myCombobox.addItemListener(this);

}

public void itemStateChanged(ItemEvent e){

Color currentcolor = Color.decode(getValue());

colorButton.setBackground(currentcolor);

}

}

Yes, I figured out it was a classpath problem too,

so I've been spending the last few hours trying

everything I can find to set and reset the classpath,

no luck. Finally I tried compiling with -classpath

and that seemed to work, I got back the prompt

without any errors, but when I went to look for

the class file...It wasn't there! Serached for it..

no luck! I'm totally stymied now and am begining

to wonder if there is a problem with my installation.

Do I have to install the J2 Runtime Environment as

well as the J2 SDK for this to work?

Thanks for the help but that didnt work. The value

of classpath when I type the set command is:

classpath=.;.;C:\Program Files\Photodeluxe 2.0\Adobe Connectables

Is this wrong? I used to have jdk1.8.1 and had the classpath

set right for that but ever since I downloaded 1.3.1 my class

path has been messed up.

The error messages I'm getting are:

C:\>set classpath=%classpath%;.

C:\>cd jdk1.3.1

C:\jdk1.3.1>javac newColorChoose.java

newColorChoose.java:26: cannot resolve symbol

Your point about the AWT applet not being compatible with swing is well

taken and in fact my java book agrees with you. As such I'm going

to try to solve the problem by combining both source codes into

one and use jApplet instead. This may be a temporary solution and

as far as my classpath goes, I may run into the same problem in the

future but I guess I will deal with that when I come to it. Thanks

for all your help js....you are definately a knowledgeable programmer!

Actually I omitted that part of the code by accident. Here

is the full code of CustomComboBoxDemo as it now stands...

(the getValue method is at the end):

import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

public class CustomComboBoxDemo extends JPanel {

String mycolor;

public CustomComboBoxDemo() {

//

String[] colorString = {"FF0000", "009900", "0000FF", "CCFF00", "CC9900"};

ImageIcon myIcon[] = new ImageIcon[colorString.length];

for (int i = 0; i < colorString.length; i++){

Image myImage = createImage(10,20);

Graphics g = myImage.getGraphics();

g.drawRect(0,0,20,10);

Color CurrentColor = Color.decode(colorString);

g.setColor(CurrentColor);

g.fillRect(0,0,20,10);

myIcon = new ImageIcon(myImage);

}

// Create the combo box

JComboBox colorList = new JComboBox(myIcon);

ComboBoxRenderer renderer= new ComboBoxRenderer();

renderer.setPreferredSize(new Dimension(50, 20));

colorList.setRenderer(renderer);

colorList.setMaximumRowCount(10);

// Layout the demo

setLayout(new BorderLayout());

add(colorList, BorderLayout.NORTH);

setBorder(BorderFactory.createEmptyBorder(20,20,20,20));

}

public static void main(String s[]) {

JFrame frame = new JFrame("Pick a Color!");

frame.addWindowListener(new WindowAdapter() {

public void windowClosing(WindowEvent e) {System.exit(0);}

});

frame.getContentPane().add(new CustomComboBoxDemo(),

BorderLayout.CENTER);

frame.pack();

frame.setVisible(true);

}

class ComboBoxRenderer extends JLabel implements ListCellRenderer {

public ComboBoxRenderer() {

setOpaque(true);

setHorizontalAlignment(CENTER);

setVerticalAlignment(CENTER);

}

public Component getListCellRendererComponent(

JList list,

Object value,

int index,

boolean isSelected,

boolean cellHasFocus) {

if (isSelected) {

setBackground(list.getSelectionBackground());

setForeground(list.getSelectionForeground());

} else {

setBackground(list.getBackground());

setForeground(list.getForeground());

}

ImageIcon icon = (ImageIcon)value;

mycolor = icon.getDescription();

setText(icon.getDescription());

setIcon(icon);

return this;

}

}

public String getValue(){

return mycolor;

}

}

This is intended to go in a html form page. Using javascript, I know that

I can access the getValue method to find what value a user chose. Its

fairly simple but if you ever have need for it it looks like this:

<script LANGUAGE="JavaScript">

function getColor(){

var color = document.newColorChoose.getValue();

return true;

}

</script>
