MVC Layout - Adding Listeners?
May 4, 2014
So I'm doing a basic MVC layout for a pretty basic game that I am making in order to understand the whole MVC layout. The game requires the user to move up/down/left/right via JButtons on the GUI. Since I'm using an MVC layout and my buttons are in a different class than the ActionListeners, I was wondering what the best way to add the action listeners are?
Method 1:
View Class ActionListener method:
Java Code: public void addMovementListeners(ActionListener u, ActionListener d, ActionListener l, ActionListener r){
moveUp.addActionListener(u);
moveDown.addActionListener(d);
moveLeft.addActionListener(l);
moveRight.addActionListener(r);
[Code] ....
Which method is better? Is there another method that is even better than these two? Trying to get this MVC thing down.

I like to adding a scrollbar to a jpanel with flowlayout but is imposible, i don't see the scrollbar. I've tried a thousand different ways but I have not accomplished anything.
Here is my code:
//Creamos el panel que contendra los botones de cada producto diferente
package com.foolsrecords.tpv.tablaproductos.vista;
//Hacemos todas las importaciones necesarias
import com.foolsrecords.tpv.modelo.Producto;
import com.foolsrecords.tpv.modelo.eventos.ControladorEventListener;

I am having some issues with my GUI. I have a UserList GUI (not finished) that, on button click, will check for an open chat window and open a new window if none exists or add a tab if one does (this is working fine). My issue is that the listeners I added to my chat window only work for the last tab added. If I switch back to a previous tab, I can no longer use my input textField and send button to write to my textArea. I add listeners when I initially create the window and first tab. I thought about adding ChangeState listener, but couldn't work out how it would be any different than what I am doing now. Do I not fully understand how listeners are added to a particular object?
I will post my code for the whole class so you can get the full picture.
Java Code: public class Chat extends JFrame{
private JPanel tabPanels, mainPanel;
private JTextArea chatArea;
private JTextField inputArea;
private JButton send;
private JTabbedPane tabPane;
private JScrollPane scroll;
private String name;
[Code]...

I am making an MVC program and I am not allowed to put the action listeners in the view class. I was able to get one button working fine but since I am unable to reference them I cannot give them both individual responses.
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class Controller {
HobbyList model;
ListView view;
[code]....

My output is all over the place. I cancelled out the borderlayouts beneath each panel I created and it completely changed the output, and I'm not sure why. The first photo below, shows what it looked like with the layouts and the second shows the output without. I still don't understand why I don't see the digits 1-9.
Java Code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionListener;
public class Atm extends JFrame {
Atm(){
super("ATM");
//Create Panels For ATM
JPanel buttonPanel1 = new JPanel(); //To Contain Digits 1-9
[Code] ....
Why would setting the layout beneath each object change the layout so much? I stayed consistent in my use of BLayout and GLayout in the program.

How the event Listeners work in java,To get the data based on the event occurs in outside the application. I have this method in one of my API class I am not understanding how this methods are going to work.
public interface SBXPCXMLEventListener {
public void OnReceiveEventXML(String eventXML);
}
private static List<SBXPCXMLEventListener> listenerList = new ArrayList<SBXPCXMLEventListener>();
protected static void fireXMLEvent(String xml) {
[Code] ....
I have done like this.This is used to capture the events from the fingerprint machine when run this class I am not getting any data from the machine when i did thumb impression in the machine.
public class EventListnere implements SBXPCXMLEventListener {
public static void main(String[] args) {
boolean flag = SBXPCProxy.ConnectTcpip(1, "10.0.0.8", 5005, 1234);
System.out.println("flag = " + flag);
// SBXPCProxy.st

So im making a calculator just basic 4 function with a clear button. as i am working into this project i am running into an issue of assigning which click sets what. For instance i click the two button how do i tell it to assign it to firstNum, versus secondNum?
private class theHandler implements ActionListener{
public void actionPerformed(ActionEvent event){
if(event.getSource()==one){
firstNum=1;
}
if(event.getSource()==two){
secondNum =2;
}
if(event.getSource()==three){
secondNum =3;
}
So this for instance allows me to set one to the firstNum and then add it to two or three but im not sure what to do next. I have in my mind i want to do something like make three listener classes, that operate in sequential order like you pick the first numbers, click an operation, and then select the second numbers then hit the operation(equal) button to display answer. Am i on the right track or what?

I am having trouble with a jTable that I am using. I have set the listeners of the cells to save the information of the entire table every time they are modified, but run into the problem that the last modified cell does will not reflect its most recent value. The value will display visually, but not show up when I try to read from the cell. I have tried wrapping the saveProcGuide() call in swing's invokelater, but to no avail. I have marked the area where the problem becomes evident (values returned do not match those present in the visible table object). Below is the offending code:
// This is where I set up the listeners
private void addProcGuideWithValues() {
procTableModel.addRow(new Object[]{"", ""});
// document listener to be fed into editor/renderers for cells...
DocumentListener docuListener = new DocumentListener() {
public void changedUpdate(DocumentEvent e) {
saveProcGuide();

I'm making a Pacman look-a-like game, now I'm making the map out of an 2D array (as a grid). I already initialized the 2d array spots with "0" and "1". I managed to do this but now I'm stuck.
I want to use the "0" and "1" to print the map. For example the "0" are grass and the "1" are walls. The map should be printed within a JFrame. And I would like to make the width and height 32x32 pixels.
I searched on the internet and i found a couple of example codes but non of it seems to work properly. This is the code I'm using to make the 2D array and initialize the spots.:
public class Level1 extends javax.swing.JFrame{
final int ROWS = 17;
final int COLS = 17;
int[][] field = new int[ROWS][COLS];
public Level1() {
initComponents();
setLocationRelativeTo(null);

How to implement GridLayout. In my applet, I want to make a grid of 2 rows and 2 columns. In each grid I want to add a Label and a TextField. I want the background to be red.
So my code would be?
import java.awt.*;
import java.applet.*;
import java.awt.event.*;
public class GridLayoutApplet extends Applet implements ActionListener{
// construct components
Label fNameLabel = new Label("First Name");
TextField fNameField = new TextField(20);
[Code] .....
I have read about panels and frames but, it is all confusing to me. How can you add a label and a TextField to one square of the grid?

I'm just trying to do a simple JFrame class, with standard menubars, labels, buttons, etc. So far, it looks really bad. The only way I can get it to look somewhat decent is if I pack it, but then the GUI is too thin. When I resize it manually, I can get the correct position by sizing it to something specific, but it obviously changes when resized again, and I don't want to set dimensions, if my users are just going to resize it, and mess it up. I want the labels on the left, textboxes neatly to the right of them, and the button somewhere on the bottom.
I also want to dynamically create a new label, textbox and button when they click on "Write File" from the menu bar - I assume this is just done with action listener, but I have enough problems as it is with formatting my layout, that I don't even want to start on it!
import java.awt.Color;
import java.awt.FlowLayout;
import java.awt.GridLayout;
import javax.swing.JButton;
import javax.swing.JFrame;

Below is my assignment and as you can see there is lots of empty space and it looks a bit ugly. Im currently using
content.setLayout(new GridLayout(5,1));
as follows:
Welcome Label and four buttons in the top JPanel,
"Employee count" and JTextField in the second JPanel,
"Employees in System: ", and empty JList in the third JPanel,
Delete employee and Edit Employee buttons in the fourth JPanel
Exit button in last JPanel.
When I set the size any smaller, the buttons sort of shrink into each other so Im looking for a way to have the panels take up less space? At the moment it seems like each of the panels are set to the same size for some reason, regardless of the content.how can I give the frame less vertical height without ruining the content.

I want to make a calculator program as my first ever program and I've been working on the layout and I think I have it close to where I want it but will probably tweak it in the future after I get it to work. My problem is I'm trying to add a MenuBar to it but it is not showing up. I tried having it all over my code but whereever I put it the MenuBar doesn't show up.
public class MySecondCalculator extends JFrame {
JTextArea screen;
JMenuBar mb;
JMenu file;
JMenuItem open;
JButton one, two, three, four, five, six, seven, eight, nine, zero, decimal, add, subtract, multiply, divide, equals;

I create a spring layout like so
Container contentPane = this.getContentPane();
JLabel characterLabel = new JLabel("Character: ");
JComboBox<String> characterComboBox = new JComboBox<String>();
characterLabel.setMinimumSize(characterComboBox.getMinimumSize());
[Code] ....
and I have attached an image of the results.
Why are the drop down boxes not stretched to the right all the way and why are they so tall?

I have developed a web portal using jsp and struts 2. I have approximately 10 JSP pages which looks exactly the same and have two text areas and two hidden fields. All 10 pages are exactly the same except for hidden field value. Can't i have a single common jsp page. How can i achieve it. A sample page i am attaching...
<%@ page contentType="text/html; charset=UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%@ page pageEncoding="UTF-8"%>
<%@ page language="java"%>
[Code]....
As this is an Assignment page so hidden field value is assignment. If the page is OBJECTIVEs then value will be OBJECTIVE.

I would like to implement a custom Logging strategy for my Java project.I have implemented 3 appenders : one console-log, one file-log (errors only) and another (custom) file-log (with the custom parameters).The custom parameters are : loggerName, logPathDir, logFileLevel and layoutPattern.
I have not managed yet to implement a custom layoutPattern strategy for the custom file-log.When I launch my tests : test1 (default logging setting) and test2 (custom logging setting), I have only managed to get a sucessfull status if I switch the custom layoutPattern strategy to the default one for the test2. My implementation extract :
// Layout patterns : default (layout) and custom (patternLayoutCustomBuilt)
Layout<String> layout = PatternLayout.createLayout(PatternLayout.SIMPLE_CO NVERSION_PATTERN, config, null, null, false,
false, null, null)
PatternLayout.Builder patternLayoutCustom = PatternLayout.newBuilder();
PatternLayout patternLayoutCustomBuilt = patternLayoutCustom.withPattern(layoutPattern).wit hConfiguration(config).build();

After generating a. JAR with Netbeans Java, when I play I see the colors of the components, the design and formatting is lost and the form gets a very basic formatting, for example, if I set a button with the color [0, 40.255] and build the. JAR after this, when I run the. JAR this button turns gray, and it happens with all the layout of the form.
settings:
Netbeans 8.0
Windows 7
