The ButtonPanel Class

This class can be used to create a panel with five buttons. The ButonPanel class uses the SwingComp class to create buttons.

Listing 15.2 ButtonPanel.java

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

//class used to create a button panel
public class ButtonPanel extends JPanel{

 //constructor 
  public ButtonPanel(ActionListener listener){
	 
	super(new GridLayout(1,4));
	
	//create buttons
	SwingComp.createButton(this,listener,"Add");
	SwingComp.createButton(this,listener,"Update");
	SwingComp.createButton(this,listener,"Delete");
	SwingComp.createButton(this,listener,"Clear");
	SwingComp.createButton(this,listener,"Find");
	 
	//set the border of the panel
	setBorder(BorderFactory.createEtchedBorder(
			Color.white,Color.black));
	}
}

The design of both the classes is very simple.
