java 程序设计，用JList显示各种颜色（如红蓝绿），选中某中颜色后，文本框中的文字的颜色相应的改变？

求助
最好用java 组件中的JApplet编写
求java高手
用Swing组件编写，能实现上述的要求

Answer 1

参考。JColorChooser
可以用Java Swing里面的颜色选择器：JColorChooser
例子如下：

public class Color extends javax.swing.JFrame {

public Color() {
initComponents();
}

@SuppressWarnings("unchecked")
// <editor-fold defaultstate="collapsed" desc="Generated Code">
private void initComponents() {

jColorChooser1 = new javax.swing.JColorChooser();

setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

org.jdesktop.layout.GroupLayout layout = new org.jdesktop.layout.GroupLayout(getContentPane());
getContentPane().setLayout(layout);
layout.setHorizontalGroup(
layout.createParallelGroup(org.jdesktop.layout.GroupLayout.LEADING)
.add(layout.createSequentialGroup()
.addContainerGap()
.add(jColorChooser1, org.jdesktop.layout.GroupLayout.PREFERRED_SIZE, org.jdesktop.layout.GroupLayout.DEFAULT_SIZE, org.jdesktop.layout.GroupLayout.PREFERRED_SIZE)
.addContainerGap(org.jdesktop.layout.GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE))
);
layout.setVerticalGroup(
layout.createParallelGroup(org.jdesktop.layout.GroupLayout.LEADING)
.add(layout.createSequentialGroup()
.add(jColorChooser1, org.jdesktop.layout.GroupLayout.PREFERRED_SIZE, org.jdesktop.layout.GroupLayout.DEFAULT_SIZE, org.jdesktop.layout.GroupLayout.PREFERRED_SIZE)
.addContainerGap(46, Short.MAX_VALUE))
);

pack();
}// </editor-fold>

public static void main(String args[]) {
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
new Color().setVisible(true);
}
});
}
// Variables declaration - do not modify
private javax.swing.JColorChooser jColorChooser1;
// End of variables declaration

}
