Question

Anyone has a simple poll I can use or look at to give me an idea of how to do one? Something with radio button, and when a user chose a button it adds one to the total of that selection but minuses the other percentages of the other selection....something like that. And maybe using a graphical bar....hmmmm this looks hard already.

Answer 1

Something like this?import javax.swing.*;
import javax.swing.event.*;
import java.awt.*;
import java.awt.event.*;
public class Test extends JFrame {
  JSlider[] js = new JSlider[5];
  int[] oldValues = new int[5];
  boolean isAdj=false;
  public Test() {
    JPanel content = (JPanel)getContentPane();
    content.setLayout(new BoxLayout(content, BoxLayout.X_AXIS));
    for (int x=0; x<js.length; x++) {
      js[x] = new JSlider(JSlider.VERTICAL,0,100,50);
      js[x].addChangeListener(new ChangeListener() {
     public void stateChanged(ChangeEvent ce) {
       if (!((JSlider)ce.getSource()).getValueIsAdjusting()) sliderSlid(ce);
      content.add(js[x]);
    this.setDefaultCloseOperation(this.EXIT_ON_CLOSE);
    addWindowListener(new WindowAdapter() {
      public void windowClosed(WindowEvent e) { System.exit(0); }
  private void sliderSlid(ChangeEvent ce) {
    if (isAdj) return;
    isAdj=true;
    int newTot=0;
    JSlider thisSlider = (JSlider)ce.getSource();
    int thisVal = thisSlider.getValue();
    System.out.println("TV="+thisVal);
    for (int x=0; x<js.length; x++) newTot+=js[x].getValue();
    System.out.println("NT="+newTot);
    double scale = (250.-thisVal)/(newTot-thisVal);
    System.out.println("SC="+scale);
    for (int x=0; x<js.length; x++) {
      if (js[x]!=thisSlider) js[x].setValue((int)(js[x].getValue()*scale));
    isAdj=false;
  public static void main(String[] args) {
    Test test = new Test();
    test.setSize(200,200);
    test.show();
}
