How to use ScrollPane class?

[Gokul20]

Hi Friend,

I just started to learn the class concepts of the advanced java programming. While this I am not getting the use of ScrollPane class of java. I don't know anything about methods and constructors of the ScrollPane class. If you has good knowledge about this ScrollPane class of java, then please let know that. You any help over this java class would be greatly appreciated.

The ScrollPane class is a container class which implements automatic horizontal and/or vertical scrolling for a single child component. The state of the horizontal and vertical scrollbars is represented by two ScrollPaneAdjustable objects (one for each dimension) which implement the Adjustable interface. The API provides methods to access those objects such that the attributes on the Adjustable object (such as unitIncrement, value, etc.) can be manipulated.

Hello friend,

I suggest you to study following methods of the ScrollPane class:

• setWheelScrollingEnabled(boolean bln)
• setScrollPosition(Point pnt)
• setScrollPosition(int ac, int ad)
• printComponents(Graphics gp)
• eventTypeEnabled(int tp)

Example of ScrollPane class:

import javax.swing.Icon;
import javax.swing.ImageIcon;
import java.awt.ScrollPane;

public class ScrollSampleDM
 {
  public static void main(String affrgs[])
{
    String t002 = (affrgs.length == 0 ? "JScrollPane Sample" : arffgs[0]);
    JFrame frameW = new JFrame(title);
    frameW.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    Icon iconW = new ImageIcon("dog.jpg");
    JLabel dogLabel1 = new JLabel(iconW);
    JScrollPane scrollPane1 = new JScrollPane();
    scrollPane.setViewportView(dogLabel1);
    frameW.getContentPane().add(scrollPane1, BorderLayout.CENTER);
    frameW.setSize(400, 200);
    frameW.setVisible(true);
  }
}

Hi friend,

Below I have given four nested classes of the ScrollPane class:

1. ScrollPane.AccessibleAWTScrollPane
2. Component.AccessibleAWTComponent
3. Component.FlipBufferStrategy
4. Container.AccessibleAWTContainer
