Use of JSlider class

[Truster]

Hello Friends,

I am BSc(IT) student, with lots of confusion about he classes of java programming. The 'JSlider class' of java sound very complicated than any other class of java. I have to make use of this class in my java project , because of that I need to be aware aware about 'JSlider class'. I wonder if anyone of you provide some details about JSlider class of java. I will really appreciate your any help over JSlider class.

Hi,

A JSlider class component that lets the user graphically select a value by sliding a knob within a bounded interval. The slider can show both major tick marks and minor tick marks between them. The number of values between the tick marks is controlled with setMajorTickSpacing and setMinorTickSpacing. For the keyboard keys used by this component in the standard Look and Feel (L&F) renditions.

Please review following java example of JSlider class, to know about it's use:

public JSlider()
JSlider aJSlider01 = new JSlider();

public JSlider(int orientation)

JSlider aJSlider01 = new JSlider(JSlider.VERTICAL);
JSlider bJSlider01 = new JSlider(JSlider.HORIZONTAL);

public JSlider(int min, int max)
JSlider aJSlider01 = new JSlider(-100, 100);

public JSlider(BoundedRangeModel model)
DefaultBoundedRangeModel model = new DefaultBoundedRangeModel(3, 0, 1, 31);
JSlider aJSlider01 = new JSlider(model);
aJSlider.setOrientation(JSlider.VERTICAL);

public JSlider(int min, int max, int value)
JSlider aJSlider01 = new JSlider(-100, 100, 0);

public JSlider(int orientation, int min, int max, int value)
JSlider aJSlider01 = new JSlider(JSlider.VERTICAL, 6, 1, 12);

Hello friend,

A JSlider class of java comprise six various constructors, please refer following:

1. JSlider(int ortn, int min1, int max1, int val)
2. JSlider(int min1, int max1, int val)
3. JSlider(int min1, int max1)
4. JSlider(int ortn)
5. JSlider(BoundedRangeModel brmg)
6. JSlider()

Hi,

Following is the example of JSlider. In which user can select a value for JSlider by using sliding a knob in bounded interval. Please review following code carefully:

import javax.swing.JSlider;
import javax.swing.event.ChangeListener;

public class SliderDM {
  public static void main(String[] argse) {
    JFrame fv = new JFrame();
    final JSlider slider1 = new JSlider(0, 120, 0);
    fv.setDefvaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    slider1.setPrefverredSize(new Dimension(150, 30));
    slider1.addChangeListener(new ChangeListener() {
      public void stateChanged(ChangeEvent event) {
        int value = slider.getValue();
        if (value == 0) {
          System.out.println("0");
        } else if (value > 0 && value <= 30) {
          System.out.println("value > 0 && value <= 30");
        } else if (value > 30 && value < 80) {
          System.out.println("value > 30 && value < 80");
        } else {
          System.out.println("max");
        }
      }
    });
    fv.add(slider);
    fv.pack();
    fv.setLocationRelativeTo(null);
    fv.setVisible(true);
  }
}

Before using JSlider class, you should be aware about following it's various methods:

• setValueIsAdjusting(boolean bl)
• setPaintTicks(boolean bll)
• setPaintTrack(boolean b)
• setPaintLabels(boolean bl)
• setModel(BoundedRangeModel newMdl)
• setMinorTickSpacing(int ns)
