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:
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.

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 want to add only one button in a JFrame by using Mig Layout, dock south as BorderLayout.South does . Is it possible?
View Replies View RelatedSo 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've got the layout put correctly but I can't seem to get my action listeners to work correctly.

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());

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?
My IDE has a visual editor for creating Swing applications. The created application windows have no layout manager and use method "setBounds()" for placing Swing components on the application window. I have built an application that uses JInternalFrame. Each JInternalFrame is a separate and different "screen" for the user to interact with.
There are around 2,000 screens in the application and new screens are constantly being added as well as existing screens being modified. As a result, the top-level container - a JFrame - is a fixed size and is not resizable. I have now been asked to increase the size of the JFrame while maintaining the proportions of the screens.
Rather than manually editing the invocations of "setBounds()" on all the screens, any alternative way to achieve this? Also, is there a way to achieve this such that if, in future, the JFrame will again be resized, the screesn will automatically adjust?
I'm trying to build a GUI that must look lik on the image above. There must be three JPanles, the one above, with buttons and combo boxes, must have fixed height and all three must have fixed vertical gaps between them. I'm trying laout after layout but somehow it's not working. I'm allowed to use only standard Swing layouts.

How to change the location of a grid bag positioned component after it's already been added to the layout earlier?
Example is if I want component 1 to change from row 1 to row 2.
For example, say I have I BoxLayout with a few JButtons in it. How could I make it such that I could drag a JButton such that it could be in front or behind the others?
I've thought about using ComponentMover and just switching to a null layout right before moving it and switch it back right after like bellow, but I'm not sure how to make it keep the change in order.
import java.awt.LayoutManager;
import java.awt.event.MouseEvent;
public class LayoutComponentMover extends ComponentMover

I am making an expert system using Jess about animals. I wanted to make an interface using Swing and so I did. I have a problem using group layouts. The application works fine but at the end a exceptions is thrown:
Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: javax.swing.JLabel[,0,0,0x0,invalid,alignmentX=0.0,
alignmentY=0.0,border=,flags=8388608,maximumSize=,minimumSize=,
preferredSize=,defaultIcon=,disabledIcon=,horizontalAlignment=LEADING,
horizontalTextPosition=TRAILING,iconTextGap=4,labelFor=,
text=The animal is a cheetah.,verticalAlignment=CENTER,
verticalTextPosition=CENTER] is not attached to a horizontal group
[Code] ....
The application ask the user some questions about the animal. When the expert system has enough information to know the animal it tells the name of the animal and shows a picture of it. The exception is thrown when the application has guessed the animal and shows the response.
Here is the code:
package xindria;
import javax.imageio.ImageIO;
import javax.swing.*;
import javax.swing.GroupLayout.SequentialGroup;
import java.awt.*;
import java.awt.event.ActionEvent;

I think the problem is related to the group layouts. I will attach the eclipse project too...
I have quite a specific view for how I want my components layed out. No matter what I try I can get them to display how I want! I'm using three JPanels. There's a main panel that goes inside the tabbed pane. This main panel contains two other panels. The First panel is a gridbaglayout panel, with labels on the left column, and components on the right column. The second panel is underneath the second, and contains a label, and a button beneath it. THis uses a basic box layout, with one component per line. The label doesn't always appear (depends if a component is changed). With everything showing, this is how it looks so far:
However, I want the Labels on the left of the pane. The right hand column should be aligned horizontally and have more space from the labels. Ideally I'd like a gap between the last label/checkbox and the Note label.
This is my current code for the panel/s inside the tabbed pane window.
videoPanel = new JPanel();
applyVidBtn = new JButton("Apply Settings");
applyVidBtn.setVisible(false);
warningLbl = new JLabel("Note. Applying these settings causes a program restart.");
warningLbl.setVisible(false);

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;

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.

public class Controller {
HobbyList model;
ListView view;

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.

I have an application that reads through a ResultSet... while I'm reading that ResultSet, I am creating new JButtons..... Now I need to add an ActionListener to those JButtons...... but they are not visible to the actionPerformed method. So I thought I'd try to add an ActionListener as I created the buttons with the following code:
final File file = new File(rs.getString(3));
SKPictureButton spb = new SKPictureButton(url,file.getName());
spb.addActionListener (
new ActionListener() {
public void actionPerformed( ActionEvent e )
[Code] ....
However this seems a bit excessive to me..... I don't think I really want to be creating a new ActionListener class for each JButton do I ? Is there a better way to make the JButtons created in this method visible to the actionPerformed method ? I'm just gettin' back into the "Swing" of things in Java.... haven't coded it for a while.

I'm starting to use AbstractTableModel to customize a JTable model. The problem appears when you add a record from a ResultSet to JTable object.
I've managed to insert records, but empty, I need that for every column I can see the data is there.
Leave some code I have been writing ... the method to insert records in JTable is called "insertEmptyRow" (for now).
I need some opinion that can make changes to the code of this method so you can get to see all the data in a record.
MyFirstModel:
public class TablaModeloPrincipal extends
private String algo;
private int numRegTabla;
//Agrego las columnas que quier tener en el model
private String[] columnNames = {"DNI", "Nombre", "Edad", "Dirección", "Empresa", "Contacto"};
Vector<String[]> clientes = new Vector<String[]>() ;
public ResultSet buscarResultset() throws SQLException{
ResultSet rs=null;
