Swing/AWT/SWT :: Getting Key Labels To Show In Textfield?
Apr 2, 2014
I am working on a keypad for a phone app for school. I cannot get the numbers from the keys to show up in the textField. I have made multiple tweaks, but think maybe my case statement is the problem?We did a calculator application in the class, so I have based my code off of that. Although the telephone keypad seemed much simpler to code, I can't seem to get the numbers to show up.
public void actionPerformed(ActionEvent e) {
//test for button clicks
foundKey = false;
//search for clicked key
for (int i=0; i<keys.length && !foundKey; i++)
[Code] ....

I wrote a simple random spelling game for a class project, was never able to get the labels to update when they should. I have tried .updateUI, .paintImmediately followed by .revalidate and by .repaint. Nothing seems to be working.
What the game does is show a random word for about 10 seconds, disappear and they user is to spell that word, you have 3 tries then will start over. The "brains" of the game work just fine, it is the labels updating with new text when they should doesn't seem to be working. There is 4 classes but the below is the "Main" that has the problems. Also have a null exception problem with the timer.stop(); not sure why. I am still pretty new to java.
Public class SpellMe extends JFrame {
// variables
JPanel mainPanel, secondPanel, thirdPanel;
JLabel mainLabel, wordLabel;
String spWord, sp;
JTextArea guess;

I'm not sure what I'm doing wrong but none of the buttons will show below. I tried using .add with the container name but it kept giving me an error. When I just put add.(); it seems fine but then nothing shows. Is there something I'm missing that's required?
import java.awt.Container;
import java.awt.FlowLayout;
import javax.swing.JButton;

I've recently decided to learn Java on my own using internet material such as forums, blogs and you tube. Ive never programed before but through some research I concluded that Java is going to be on the mid spectrum of difficulty as far as verbiage goes. I ma in no way implying that Java is easy but instead closer to spoken English that c++ if my research is correct. So here is my attempt at a basic program where I click a button and it will make an image appear. Not sure where Im falling short
package clicktoimage;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Clicktoimage extends JFrame {
private JLabel label;
private ImageIcon image;
[Code]...

I am trying to make a game with an image on it, and I have one class that gets the image and the other is the game. When I run the program, it just shows my image on a gray JFrame. This leads me to think the image might be covering my whole game, which is weird because it is a mostly transparent image. I have tried resizing it and everything but I don't know what to do..
Here is my image class
Java Code:
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

Here is the code.
loadBtn.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent arg0) {
JPanel msgPanel = new JPanel(rootFrame);
// Show the message JPanel

There is a Jlist(Jlist1) which is populated with the columnNames from MYSQL. Then There is another empty Jlist (Jlist2) which the user can add items from Jlist1. At this stage I want to know how I can select items of JList2 from MYSQL to show in Jtable. Because the columnnames(items) of Jlist2 is less than the Jlist1. Like Spss that when you select variables from available list then you can add some of variable to selected list and do analysis.
