Adv Java - [Swing: Slider/Progressbar]

♠ Posted by Unknown in Adv Java at 00:50

Sliders & Progress bars

A slider allows the user to input data by moving a point back and forth, which is intuitive in some situations. A progress bar displays data in a relative fashion from “full” to “empty” so the user gets a perspective.

 

Example:

import javax.swing.*;

import java.awt.*;

import java.awt.event.*;

import javax.swing.event.*;

import javax.swing.border.*;

public class Progress extends JApplet

{

          JProgressBar pb = new JProgressBar();

          JSlider sb = new JSlider(JSlider.HORIZONTAL, 0, 100, 60);

         

          public void init()

          {

                   Container contentPane = getContentPane();

                   contentPane.setLayout(new GridLayout(2,1));

                   contentPane.add(pb);

                   sb.setValue(0);

                   sb.setPaintTicks(true);

                   sb.setMajorTickSpacing(20);

                   sb.setMinorTickSpacing(5);

                   sb.setBorder(new TitledBorder("Slide Me"));

                   pb.setModel(sb.getModel());

                   contentPane.add(sb);

          }

}
