I'm doing a project for my class and I'm working on the GUI right now. I don't have much because, well, it's not showing up and it's infuriating. Here's my code. public class BookQuizGUI extends JFrame implements ActionListener { private Container c; private JPanel pnlButtons; private JButton addQs; private JButton takeQuiz; private JButton quit; private Container c2; private JPanel pnlButtons2; private JComboBox qType; private JComboBox ans; private JTextField q; private JTextField cA; private JTextField cB; private JTextField cC; private JTextField cD; private JButton add; private JButton

I am fairly new to some intermediate concepts in Java. Recently I made a text adventure game called DazzleQuest that runs entirely in the developer console/terminal. It involves my friends as characters so I wanted to show it to them and gain experience with Java by transferring the functionality of the command line and output from the console to a simple Swing interface comprised of a JTextArea to show the game's output and a JTextField , with ActionListener , to handle commands from the user. My main DazzleQuest class contains methods called run() and handleCommand() , which I figure I need

My code is basically about having a frame and it has a button. You press the button you can draw rectangles, getting coordinates from the mouse press and the mouse release. Now, if you remove the button the code works perfectly, here is the code. //testing file package ActionTest; import java.awt.*; import javax.swing.*; public class MouseTest { public static void main(String[] args) { EventQueue.invokeLater(new Runnable() { public void run() { JFrame frame = new MouseFrame(); frame.setTitle("MouseTest"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setVisible(true); frame

I'm trying to learn Swing on my own. I'm playing with a toy program that asks the user to input their name. I put a JLabel and JTextfield into a JPanel where the user can input their name and submit. However my JTextfield is squished up and invisible and I can't get it to show (I've tried "setSize" to no avail). This is my code: import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.JTextField; public class NamePrompt extends JFrame{ private static final long serialVersionUID = 1L; String name; public NamePrompt(){ setLayout(new BorderLayout());

I can't seem to figure out why my JFrame is empty. Where am I going wrong? import javax.swing.*; import java.awt.FlowLayout; public class GUIExample extends JFrame { JCheckBox box1 = new JCheckBox("Satellite Radio"); JCheckBox box2 = new JCheckBox("Air Conditioning"); JCheckBox box3 = new JCheckBox("Manual Tranmission"); JCheckBox box4 = new JCheckBox("Leather Seats"); JRadioButton radio1 = new JRadioButton("Car"); JRadioButton radio2 = new JRadioButton("Pickup Truck"); JRadioButton radio3 = new JRadioButton("Minivan"); JTextField text = new JTextField(); ButtonGroup group = new ButtonGroup();

I'm trying to make a gui with two menu lists, with 3 items in each. What my problem is, is that when I click on an item, I get an error "The method displayList(int, AirplaneList) is undefined for the type JFrame" Code for AirplaneController.java: import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.JFrame; import javax.swing.JOptionPane; import java.util.StringTokenizer; public class AirplaneController implements ActionListener{ public static StringTokenizer myTokens; //Declares a string tokenizer. public static String[] animals; public static int i;/

I'm working on a really simple project in Java to try to understand how to use KeyListener. I've created a Main class and a KeyListener, MouseListener class. I want to get something to happen when I press a keyboard key. So far the only thing that is working is "Hello" when I click. Here is my code: import javax.swing.JFrame; import javax.swing.JPanel; public class KeyPractice{ public static void main(String[] args) { JFrame frame = new JFrame(); JPanel panel = new JPanel(); panel.addKeyListener(new KeyEar()); panel.addMouseListener(new KeyEar()); frame.add(panel); frame.setVisible(true);
