Laboratory 4
Chapter 14: GUI Components, Part 1

Before the lab, do the Self-Review exercises in the chapter.

Put the Java source code of your solution to the exercise below on your private GitHub repository:

Feel free to talk to whomever you like about any aspect of the laboratory. Working in pairs may be helpful.

Chapter 14

Make a Java application whose control panel looks like the screen shot below.

Use the following top-level App class. Your job is to define the Contoller class.

App.java

import java.awt.BorderLayout;
import java.awt.Dimension;
import javax.swing.JFrame;

/**

public class App extends JFrame
{
    private static final int HEIGHT = 230;
    private static final int WIDTH = 450;
    
    private final Controller controller;
    
    App() 
    {        
        controller = new Controller(); 
        
        setTitle( "Printer Control Panel" );
        setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
                      
        add( controller, BorderLayout.CENTER );
        
        Dimension dimension = new Dimension( WIDTH, HEIGHT );
        setSize( dimension  );
        setPreferredSize( dimension );
        setVisible( true );
    }
    
    /**
     * Run the Graphics Virtual Machine application.
     * @param args unused 
     */
    public static void main( String[] args ) { App app = new App(); }
}

Notes

The filed to the right of the "Printer:" JLabel is a JTextField.
The filed to the right of the "Printer Quality:" JLabel is a JComboBox.
To get the layout above, I used, among other things, the JLabel.setHorizontalAlignment method. Please see JLabel's Javadoc.
