slider problem

[shanaya dutt]

I need my slider to show each integer value from 1 to 800000.However each time i move the slider the next value after 1 it reads is 1372.i don't know why?

here's the code snippet

  
final JSlider slider=new  JSlider(JSlider.HORIZONTAL,0,751658,0)
slider.setBorder(BorderFactory.createTitledBorder("Positions"));	
    	slider.setMajorTickSpacing(100000);
    	slider.setMinorTickSpacing(1);
        slider.setPaintTicks(true);
	slider.setPaintLabels(true); 
  

please tell me where I'm going wrong and what should i do?

you have a 3-mile wide screen?

> However each time i move the slider the next value after 1 it reads is 1372.i don't know why?

wild guess, 1372 represents 1 pixel or slider.maxValue/slider track width (something like that, anyway)

[shanaya dutt]

so,is there any way i can show each value?

a very wide screen,
or you could use a smaller number, 8000, setting your own label to look like
majorTickSpacing of 100000, then multiply the slider's value x 100

I think you can still use the original range for the slider, but Michael is right about the tick spacing. Use larger intervals, like 10000 for minor and 100000 for major. Also, you'll probably have to change the preferred size.

I tried the following and after resizing a bit manually, it worked just fine:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;

public class Test implements ChangeListener
{
    public static void main(String[] args) throws Exception
    {
        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        final JSlider slider=new  JSlider(JSlider.HORIZONTAL,0,800000,0);
        slider.setBorder(BorderFactory.createTitledBorder("Positions"));
        slider.setMajorTickSpacing(100000);
        slider.setMinorTickSpacing(10000);
        slider.setPaintTicks(true);
        slider.setPaintLabels(true);
        slider.addChangeListener(new Test());
        frame.add(slider);
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }

    public void stateChanged(ChangeEvent e)
    {
        JSlider slider = (JSlider)e.getSource();
        System.out.println(slider.getValue());
    }
}
