Creating a java swing album

I'd like to create a Java Swing Photo Album but I can't manage to find the right way to do it. I think it should be to create two ArrayList, one to stock the photo objects and another one to stock the buttons.
After that I should find a way to assign each images to the buttons and add them into the panel.
My question is : Do you think it is the right way to do it and if so, could you give me a hint? (For the last class at the bottom)
Here's my code at the moment :
Main :
import javax.swing.JFrame;
public class Main extends JFrame {
public static void main(String[] args) {
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
new AlbumFrame();
}
});
}
}
AlbumFrame :
import java.awt.BorderLayout;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
public class AlbumFrame extends JFrame {
private JPanel MenuPanel;
private JPanel PhotoPanel;
public AlbumFrame(){
super("JPhone");
setLayout(new BorderLayout());
PhotoPanel = new PhotoPanel();
add(PhotoPanel,BorderLayout.CENTER);
MenuPanel = new MenuPanel();
add(MenuPanel,BorderLayout.SOUTH);
setSize(480,800);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
}
}
MenuPanel
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.File;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFileChooser;
import javax.swing.JPanel;
import javax.swing.filechooser.FileNameExtensionFilter;
public class MenuPanel extends JPanel implements ActionListener{
private static final long serialVersionUID = 1L;
private JButton backButton;
private JButton homeButton;
private JButton turnButton;
private JButton addButton;
final private JFileChooser fc;
public MenuPanel(){
fc = new JFileChooser();
backButton = new JButton(new ImageIcon(getClass().getResource("/Images/back.png")));
homeButton = new JButton(new ImageIcon(getClass().getResource("/Images/home.png")));
turnButton = new JButton(new ImageIcon(getClass().getResource("/Images/turn.png")));
addButton = new JButton(new ImageIcon(getClass().getResource("/Images/add.png")));
backButton.setPreferredSize(new Dimension(55,55));
homeButton.setPreferredSize(new Dimension(55,55));
turnButton.setPreferredSize(new Dimension(55,55));
addButton.setPreferredSize(new Dimension(55,55));
backButton.addActionListener(this);
homeButton.addActionListener(this);
turnButton.addActionListener(this);
addButton.addActionListener(this);
setLayout(new FlowLayout(FlowLayout.CENTER));
add(backButton);
add(homeButton);
add(turnButton);
add(addButton);
}
public void actionPerformed(ActionEvent e) {
JButton clicked = (JButton)e.getSource();
//Test for the moment
if(clicked == backButton){
System.out.println("back");
}else if(clicked == homeButton){
System.out.println("home");
}else if(clicked == turnButton){
System.out.println("turn");
}else if(clicked == addButton){
int returnVal = fc.showOpenDialog(MenuPanel.this);
if(returnVal == JFileChooser.APPROVE_OPTION){
File file = fc.getSelectedFile();
}
}
}
}
PhotoPanel
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.ArrayList;
import javax.swing.JButton;
import javax.swing.JPanel;
public class PhotoPanel extends JPanel implements ActionListener {
ArrayList<Photo> Album = new ArrayList<Photo>();
ArrayList<JButton> Buttons = new ArrayList<JButton>();
public PhotoPanel(){
setLayout(new FlowLayout(FlowLayout.CENTER));
}
public void actionPerformed(ActionEvent e) {
}
}

I would use separate class like PhotoCard to avoid lists:
class PhotoCard {
public PhotoCard(Photo photo) {
add(photo);
// also add buttons, listeners, etc.
}
}
that holds necessary data and initializes listeners.
And then class can be added to to your PhotoPanel:
PhotoPanel.add(new PhotoCard(...));

Need help resetting JComboBox

So I am trying to make a Fahrenheit to Celsius (or vice versa) conversion program. So it sort of works but I have a drop down menu which I take the value from to check which conversion equation I need. My program isn't quiet finished I only have one equation but It doesn't go back to normal once I've pressed convert. Does anyone know how I can refresh so it goes back to the first option?

System.out.print(Options.getSelectedIndex());

ListSelection Listener not firing event

does anyone know why
System.out.println(e.getFirstIndex());
System.out.println(e.getLastIndex());
both does nothing? is my Listener not registered properly? i am trying to know when a certain cell is selected and do something to it. Like setting a default text for that cell when it is selected either by mouse or key.

public void valueChanged(ListSelectionEvent e) {
ListSelectionModel lsm = (ListSelectionModel)e.getSource();
System.out.println(e.getFirstIndex());
System.out.println(e.getLastIndex());
}
}

The problem is, the row is already selected.
The tables selection model relates to the selection changes of the rows.
If you change the order in which you register the listener as follows...
JTbl.getSelectionModel().addListSelectionListener(new cellSelectedListener(JTbl));
JTbl.setColumnSelectionInterval(0, 0);
JTbl.setRowSelectionInterval(0, 0);
You will see the row selection change.
Update code review...
Generally, this JTbl.setPreferredScrollableViewportSize(JTbl.getPreferredSize()); is not a good idea. You really want to leave it up to the scroll pane to make these kind of decisions. You can alter the column sizes if you really want to effect the width of the table.
Java naming conventions suggest that all instance variables start with a lower case character, soJTbl would become jTbl and all classes start with an upper case, so mainFrame would become MainFrame...small thing, but it's what people are really use to.

SwingX AutoCompleteDecorator : no suitable methode found for decorate

I am trying to test SwingX for the first time,For this, I read the doc : http://www.jdocs.com/swingx/1.0/org/jdesktop/swingx/autocomplete/AutoCompleteDecorator.html
I'd like to make a suggestion on a JTextField like this:
List items = [...];
JTextField textField = [...];
AutoCompleteDecorator.decorate(textField, items);
so I create a project on netbeans, this is my code:
package test_swingx;
import java.awt.Dimension;
import java.awt.HeadlessException;
import java.util.ArrayList;
import java.util.List;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;
import org.jdesktop.swingx.autocomplete.AutoCompleteDecorator;
/**
*
* #author marwen
*/
public class Test_swingx extends JFrame {
public Test_swingx(String title) throws HeadlessException {
this.setTitle(title);
JPanel pan=new JPanel();
JTextField jtf=new JTextField();
jtf.setColumns(20);
List items = new ArrayList();
items.add("hello");
items.add("marwen");
items.add("allooo");
AutoCompleteDecorator.decorate(jtf, items);
pan.add(jtf);
this.setContentPane(pan);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setVisible(true);
this.setBounds(280, 150, 500, 200);
}
public static void main(String[] args) {
Test_swingx tsx=new Test_swingx("helloo swingx");
}
}
I get this error :
no suitable methode found for decorate....
I'm following well the syntax , I do not understand where the error come?
ANY HELPS ?

Your method decorate call, is resolve to the first method below which is incorrect. Second method decorate expected JList instead of list.
public static void decorate(JComboBox comboBox, ObjectToStringConverter stringConverter)
public static void decorate(JList list, JTextComponent textComponent)
However, if you still want to use List, you should use this method,
public static void decorate(JTextComponent textComponent, List<?> items, boolean strictMatching)
I've changed the error part in your question with this.
import java.util.ArrayList;
import java.util.List;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.text.JTextComponent;
import org.jdesktop.swingx.autocomplete.AutoCompleteDecorator;
public class Test_swingx extends JFrame
{
public Test_swingx(String p_title)
{
this.setTitle(p_title);
JPanel pan = new JPanel();
JTextComponent jtf = new JTextField();
((JTextField) jtf).setColumns(20);
List items = new ArrayList();
items.add("hello");
items.add("marwen");
items.add("allooo");
AutoCompleteDecorator.decorate(jtf, items, false);
pan.add(jtf);
this.setContentPane(pan);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setVisible(true);
this.setBounds(280, 150, 500, 200);

Test_swingx tsx = new Test_swingx("helloo swingx");
tsx.setVisible(true);

JTable add/remove rows to custom table model (updating table display)

Does anyone have a good example of how to Add/Remove rows from a JTable using a custom table model? The issue I seem to be having is how to have the table keep updating when I add or remove items.
The real simple idea here is to have an add and remove button above my table which allows the user on the fly to change the table.

Here is example for adding row:
import java.awt.BorderLayout;
import java.awt.Point;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.ComponentAdapter;
import java.awt.event.ComponentEvent;
import java.util.Vector;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.JTextField;
import javax.swing.JViewport;
import javax.swing.SwingUtilities;
import javax.swing.table.AbstractTableModel;
public class RowAdder extends JFrame {
final SimpleModel tableData = new SimpleModel();
JTable table = new JTable(tableData);
public static void main(String[] args) {
RowAdder ra = new RowAdder();
ra.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
ra.setSize(400, 300);
ra.setVisible(true);
}
public RowAdder() {
final JTextField textField = new JTextField();
setLayout(new BorderLayout());
add(new JScrollPane(table), BorderLayout.CENTER);
textField.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent event) {
tableData.addText(textField.getText());
textField.setText("");
}
});
add(textField, BorderLayout.SOUTH);
}
}
class SimpleModel extends AbstractTableModel {
Vector textData = new Vector();
public void addText(String text) {
textData.addElement(text);
fireTableDataChanged();
}
public int getRowCount() {
return textData.size();
}
public int getColumnCount() {
return 3;
}
public Object getValueAt(int row, int column) {
return textData.elementAt(row);
}
}

Checkout this tutorial about JTable:
http://download.oracle.com/javase/tutorial/uiswing/components/table.html
Specifically for table model check:
http://download.oracle.com/javase/tutorial/uiswing/components/table.html#data
I think this tutorial should answer all your question.

You have to notify the JTable object on changes of the underlying table model. The table is not observing the model but waiting for events.
After every change (or set of changes), create a TableModelEvent and call the tables tableChanged method.
