Error while updating JTable

WHAT I WANT TO DO:
I display a list of items and their characteristics in a JTable (the content is in a DefaultTableModel). Each time a user buys items, I refresh the list for all the users currently connected to the server. The client buying the item is also prompted through a JOptionPane that his order has been processed.
THE CODE:
controller.handleOrder();
JOptionPane.showMessageDialog(new JFrame(), message, "SUCCESSFUL ORDER", JOptionPane.INFORMATION_MESSAGE);Another thread calls the following function, which refreshes the list in the JTable:
public void updateFlowers(){
     // method in Controller
     setChanged();
     notifyObservers();
    |
    V
public void update(Observable arg0, Object arg1) {
     // method in Frame
     loadFlowers();
    |
    V
private void loadFlowers(){
     // method in Frame
     flowerTableModel = controller.loadFlowers();
     flowerTable.setModel(flowerTableModel);
   |
   V
public DefaultTableModel loadFlowers() {
     // method in Controller
     Object table[][]=null;
     flowers=ClientOperations.getInstance().getFlowers();
     if (flowers!=null){
          table=new Object[flowers.size()][3];
          int i=0;
          for (Flower flower:flowers){
               table[0]=flower.getSpecies();
               table[i][1]=new Float(flower.getPrice());
               table[i][2]=new Integer(flower.getInStock());
               i++;
     DefaultTableModel flowersDTM=new DefaultTableModel(table,TABLE_HEADER);
     return flowersDTM;

Updating of Swing components must be done on the EDT. Wrap the code in SwingUtilities.invokeLater() or use a SwingWorker.
Read the section from the Swing tutorial on Concurrency for more information.

Combobox in jtable

suppose you are editing a combobox in a jtable.
in the combobox, there are items like
A0
A20
C0
C20
E0
E20
my main goal is traverse and edit the table by keyboard.
when i go to a jcombobox, e.g. i hit the button C, it only focus the combo, not selecting item.
JComboBox comboBox = new JComboBox(arr){
               protected boolean processKeyBinding(KeyStroke ks, KeyEvent e,
                    int condition, boolean pressed) {
                boolean retValue = super.processKeyBinding(ks, e, condition, pressed);
                if (!retValue && isStartingCellEdit() && editor != null) {
                    //editor.setItem(String.valueOf(ks.getKeyChar()));
                    JComponent editorComponent = (JComponent) getEditor().getEditorComponent();
                    InputMap map = editorComponent.getInputMap(condition);
                    ActionMap am = editorComponent.getActionMap();
                    if(map!=null && am!=null && isEnabled()){
                        Object binding = map.get(ks);
                        Action action = (binding==null) ? null : am.get(binding);
                        if(action!=null){
                             SwingUtilities.notifyAction(action, ks, e, editorComponent,
                                    e.getModifiers());
                return retValue;
            private boolean isStartingCellEdit() {
                JTable table = (JTable) SwingUtilities.getAncestorOfClass(
                        JTable.class, this);
                return table != null

                                .getClientProperty("JTable.autoStartsEdit"));
};so if i want to write C20,
when i pressed C, it selects the combo, so after pressing 2 and 0, it searches for 20.
how can i do this not to lose the first char?

Combobox in jtable two tab problem

Hi all,
If i am using combobox for one of the columns of jtable with custom editor and renderer, it needs two tab for navigation between the cells.
How can i make it as 'one tab navigation'. Even i tried with 'isManagingfocus() return true' but...no effect.
thanx in advance.
S.A.Radha.

here I'm giving a simple sample code. Refer this..
import javax.swing.*;
import java.awt.event.*;
import javax.swing.event.*;
import javax.swing.table.*;
import java.awt.*;
public class Class1 extends JFrame {
JScrollPane jScrollPane1 = new JScrollPane();
JTable editableTable1 = new JTable(3, 3);
public Class1() {
try {
JComboBox c = new JComboBox();
c.setEditable(true);
c.addItem("a");
c.addItem("b");
DefaultCellEditor cellEditor = new DefaultCellEditor(c);
TableColumn tc = editableTable1.getColumnModel().getColumn(0);
tc.setCellEditor(cellEditor);
this.getContentPane().setLayout(null);
jScrollPane1.setBounds(new Rectangle(25, 19, 330, 180));
this.getContentPane().add(jScrollPane1, null);
jScrollPane1.getViewport().add(editableTable1, null);
addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent we) {
System.exit(0);
} catch(Exception e) {
System.out.println("Exception in Class1:"+e);
public static void main(String[] args) {
Class1 class1 = new Class1();
class1.setSize(400, 400);
class1.setVisible(true);

Size of combobox in JTable with custom cell editor

Hi All -
I have a JTable that displays a combobox in certain cells. I have a custom table model, renderer, and editor. All of that works fine. I render the combobox with the renderer, and then return the combobox as an editor in the editor so that it can drop down and actually be of use. My problem is - I set the size of the combobox with a setBounds call in the renderer, I add it to a panel, and return the panel - because I dont want the combobox to take up the entire space of the cell. This approach fails in the editor. The setBounds and setSize calls have no effect. As soon as you click the combobox, the editor takes over and all of a sudden the combobox resizes to the entire area of the cell. I assume this is because in the editor you arent actually placing anything - your simply returning the "editing form" of the component.
So - anybody know of a way to work around this? Worst case, I could just allow the combobox to use the entire area of the cell - but it makes it uglier so I figured I would run it by the forums.
Eric

Rather than just redirect you to my previous answer from ages ago, I'll just give it again. :-)
You can actually do this, but you have to get tricky. By default, the dropdown's width will be the same width as the cell... but it doesn't have to be that way. Essentially what you have to do is override the UI (MetalComboBoxUI) for the combo component. In your new customized UI component subclass (that you set the combo to use), modify the the createPopup() method of this UI class, and add your own logic to set the size of the popup before you return it.
Ideally the size would be based on the computed max width of a rendered item shown in the combo, but really you could set it to whatever just to see how it works.

Combobox in JTable question

Hello,
I have to make a button in a JTable that is activated with a right button and then like in a combobox appears a menue and every item in this menue should be activated with the left button and perform some action. Like in windows right click and then select smth.
My question is should I do it with Combobox and if yes how to activate it with the right button because it always listens to left button. It is implemented with action listener and I tried mouse listener but it wouldn"t listen to that. I will be glad to any solutions.
Thanx,
Miroslav

Hi,
And thank you for the answer. i think I will use jpop menu as u sujested(Thank you for that). Now I should only see how to make the render and the editor to put it in a cell in a JTable.
It should be activated with the right button, beacause my task is such and because I also think that it is better this way. II mean it is more natural than with the left button.
Miroslav

Escape key "dies" in combobox and JTable

I have set in my JDialog the default key ESCAPE as this standard code:
          KeyStroke escKey = KeyStroke.getKeyStroke(KeyEvent.VK_ESCAPE, 0);
          int param = JComponent.WHEN_IN_FOCUSED_WINDOW;
          root.getInputMap(param).put(escKey, "close");
          root.getActionMap().put("close", actionCancel);
     this.btCancel.setAction(actionCancel);
The problem is when I have JComboBoxs and JTables. All key events seem to be consumed
In this components (and maybe more components). So, if I press ESCAPE and my focus
in a combobox, the dialog won't close.
How could I work around this?
thank you

I've got the solution!
I have a javaBean (JPanel) that has only one JComboBox. I trigger key pressed (don't know
if should be key released in this case) on comboBox. Then I check if...
this.comboBox.isPopupVisible().
Simple. If popup is not visible and dispatch the event to this.
I just wonder how the event goes to my javaBean, my javabean is in a dialog and this
dialog of mine ends up to catch the event. ???
Ok, this stays has a solution for future developers to found - in case they guess that
right keywords :)

Click ComboBox in JTable to times before editing ?

Hi,
I have a JComboBox in a JTable.
Now I want to open the ComboBox when
you click the cell to times.
There is a method in DefaultCellEditor called
setClickCountToStart(int).
But how can I get the reference to the DefaultCellEditor
from my JTable. There is only a method theTable.getDefaultEditor
which returns TableCellEditor ?
Thanx Stephan

I made it run right in jdk1.3.1 throgh chage the setSelectedItem Method, code is follow:
public void setSelectedItem(Object item) {
    this.insertItemAt(item, 0);
    if(getItemCount() > 1) {
      this.removeItemAt(1);
    super.setSelectedItem(item);
}

How to have a combobox in JTable column header?

Any simple ways for doing this? I am trying to get a filter to a JTable, so that only the rows containing the selected value in that column would be shown.
I first need to get this combobox into the header of a column.

Thanks.
I have already tried with this way, but it was too long and complicated to implement into my file.
Could someone post the principles here.
Like this:
// create my combobox
JComboBox myBox = new JComboBox();
myBox.addItem("Cat");
myBox.addItem("Dog");
// put the combobox to column header
??? ANY CODE HERE ???
Tnx ahead!
OK!

How to add ComboBox in Jtable Header

Hello everyone,
I want to add a Combox box in JTable Header .Basically it works as central access to whole table e.g. by selecting delete row in combo box then it should delete the current selected row.If somebody has any idea please share it.
Thanks in advance.

The individual headers are not Swing components and therefore do not respond to mouse events in the same way as Swing components. Why don't you just have a popup menu that is positioned over the currently selected row? If you want to apply an action to all selected rows then have a set of buttons placed above the table header.

Need combobox with a Jtable to view client & server files

Hellow Everybody,
I am quite new to Java, although I have experience with other

The above given code is not yet complete. I want some specific features to be implemented in this code that is given below.
1. A login Gridlayout or Borderlayout & within it the username & password textfield.
2. When the username and password will request to server and if it will success then the textfields of the username & password have to be disable.
3 . Two Combobox. One will give client directories and files and another
will give the server directories and files.
4 . Below the Combobox two JTable will be given & the tables wll show the
client and server directories and files.
Could anybody give me the codes that I want. If anybody check this code please help me????
With Regards,
DILLU

Well Mr Michael_Dunn,
Thanks for responding my query. First of all I would like to tell that
this FTP server is going to be my project and that's why I am submmiting my question. I told in my points that I want a Jcombobox & a JTable for displaying that files & directories. whenever I set the directories in the combobox the files will be displayed in the JTable
I hope you understand my point
