Progressbar in JTable
Hi
I have added a progressbar to a jtable. but when i add a new record, the earlier record's progressbars are edited. the rows/records are added at random, as the download progresses.
how do i tackle this problem?
Pls help me out. i have only 3 days left to complete my project.
I am not able to understand what u r asking ?
But I think you problem is you are not able to edit all table cell.
I think for JTable u have implemented Renderer and Editor than in Editor's
isCellEditable(java.util.EventObject eventObject)
u need to return true than only you will be able to edit all cells.

Returning index of selected comp... jComboBox that is editing a jTable cell
so, i'm using an array to populate the choices of a combobox
public String[] progCodes = new String[]{"Standard","Restricted","Combined","Special"};which i'm using to edit a cell in a jtable
baseCatTable.getColumnModel().getColumn(4).setCellEditor(new DefaultCellEditor(new JComboBox(progCodes)));and when i get the value
System.out.println(baseCatTable.getValueAt(0, 4))i'd like to return the index of the selected item in the combo box instead of the text:
Standard
any suggestions?

Hi,
I have written a cell renderer for a progress bar but I can't set its string or make it indeterminate. Has anybody done this before? Should I write my own, or use JProgressBar (currently using JProgressBar).
any help would be brilliantHere is a little example I made which shows the JProgressBar being updated.
Everytime a row is clicked the progress bar adds one percent
import javax.swing.*;
import javax.swing.table.*;
import java.awt.*;

import javax.swing.event.ListSelectionListener;
public class TableProgress extends JFrame{

{"John Adams","50",createBar(50, "50%")},
{"Ben Franklin","75",createBar(75, "75%")},
{"Karl Marx","0",createBar(0, "0%")},
{"Gandalf","20",createBar(20, "20%")},
{"Clint Eastwood","55",createBar(55, "55%")}
final JTable theTable = new JTable(data, headers);
theTable.setPreferredSize(new Dimension(500,100));
theTable.getColumn("Progress").setCellRenderer(new ProgRenderer());
ListSelectionModel rowSM = theTable.getSelectionModel();
rowSM.addListSelectionListener(new ListSelectionListener() {

JComboBox, JTable, cellRendering CHALLENGE
Hi all,
I would like to ask a question of the resident guru concerning a Netbeans/MYSQL application. I based it on a tutorial found here: [http://www.netbeans.org/kb/61/java/gui-db-custom.html].
I have two seperate JDialogs that write data to a master table. One of the JDialogs is called "Customer Editor" and it contains various text fields bound to cells on the masterTable, no big deal.
Also in the "Customer Editor" JDialog there is a JComboBox that has a list of four values to choose from which are "Good", "Standby", "Failed", and "Complete".
I would like the data selected from the JComboBox to color itself when it writes to the JTable row/cell on the masterTable. For example if the user selects "Good" from the list, in the masterTable the font color of the String will be GREEN. Similarly, if the user selects "Failed" from the JComboBox I would like the String to return RED...following on "Standby" - BLUE, "Complete" - no color change.
Question: How do I write code that allows me to change the color of text in a cell when it comes from a JComboBox list?
If anyone out there picks up this thread, I will of course supply the code I have so far. I won't do it now as I am not sure even where the code should go. I think it would go in the source code for the masterTable view but I am not certain.
Any Java masters out there?
DavidThanks for the reply. I have been writing different cell renderers to get it working. Where should the code reside?
This is my operations view class. Should it be in here.

Keep track of reference of a row added to Jtable
Hello All,
I need to keep track of reference of a row which is being added in JTable.
Let suppose that I adds a row in JTable based on an object (instantiated of a class say FileUploader class). Now I adds a row whenever FileUploader class is being instantiated. The FileUploader Class is responsible to upload a file.
1) Now suppose that there are 100 rows (of course based on 100 object of FileUploader class).
2) User can remove single or multiple row (by means of cancel the process of upload or clear the row in the JTable for which file has successfully uploaded).
3) I need to update a particular cell of JTable based on the status of a particular object of class FileUploader.
One way of doing this is by using for loop on whole table to find out the corresponding row (based on some key taken from table). But this will make the application very slow.
So, to do this, I need to have the reference of the row when it is being added in the JTable.
How can I make it working? Please suggest.
Thank youYou are right that iterating over 100 times is not slow. But what will happen if there are 10000 rows.
I am new to JTable. In my application, when user drag and drop some files / folder, a row is being added in the JTable to show the status of process (pending, ProgressBar, Completed or Error in one cell based on the current status of file / folder ) along with some more info in other cell ( like fileName, FromDir, ToDir, Size, and a hyperlink type text for action - clear, cancel, retry).
Now FileUploader is an class which is responsible for uploading (it has a method upload() in it which is called by a daemon thread).
So to update a particular cell (in which pending / ProgressBar/ etc is shown), I need to find the particular row which is showing the status of a file / folder.
How can I do it (without iterating over these no. of times again and again).
Is there any better approach to do this. -
How do I get at a JTable on a JInternalFrame?
I've been working on this Multiple Document Interface application, and things have been great up to this point. The user chooses to run a "report" and then selects an entity to get the info for. I then hit the database. Each row returned from the database query goes into it's own data object, which is added to an ArrayList in my custom table model, and that ArrayList is used to generate the JTable, which is then added to a ScrollPane, which is then added to the JInternalFrame, which is then added to the JDesktop pane. Good stuff, right?
I'm now trying to add Print functionality, and I'm at a loss. What I want to do is have the user do the standard File->Print, which will print out the JTable on the currently selected inner frame. I can get a JTable to print using JTable.print(). What I can't do is find a way to get the JTable from the selected frame.
I can get the selected frame using desktop.getSelectedFrame(), but I'm at a loss as to what to do next. I've played around with .getComponent, but I'm not having any luck. the components returned don't seem to do me any good...for example, JViewPort?
Am I going about this the wrong way? Have I poorly designed this? Am I missing the obvious?
Thanks,
-AdamWell, if you only have a single component on the internal frame then you can use getComponent(0). But then you need to go up the parent chain to get the actual table. You will initially get the JScrollPane, then use that to get the JViewport and then use that to get the viewport component.
Another option is to extend the JInternalFrame class and insted using the add method to add a component you create get/setTable(...) methods. Then you can save the table as a class variable before adding it the scrollpane and adding the scrollpane to the internal frame. -
JTable - Can I change the color of the text on a row by row basis?
Hi All,
I'm redoing a bit of old uni coursework (to model a stockmarket, stock ticker server & stock ticker application) to brush up my Java skills (esp Swing and Event Handling) and am programming the UI by hand using Swing (its the only way to learn something....(I've certianly nailed Layout Management!!))
In the stocktickerserver GUI I'm using a JTable to display the details about stocks.
The user can select a stock and view the details of the stock in another frame. In one panel in the JFrame I've got a JTable listing the history items for the stock (Price, Change, Date).
Is it possible to color the rows of the JTable according to the value of the change column (or at least the value I insert there)?
e.g
if (change > 0){
Blue;
else{
if (change < 0){
Red;
else{
Green;
I'm completly ignorant on how to achieve this (or even if its possible at all) so all your ideas welcome.
Any help much appreciated
Pete
P.S.
The Stock History is a class that I store in a [private] Vector in the Stock Class.
For the selected Stock I loop through this vector getting the items (using various accessor methods)
I extract the values from the return StockHistory object and build a DefaultTableModel from these
Then I call JTable.setModel(theModel) to build the tableimplement TableCellRenderer and change foreground of the Renderer in the method getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) . Install this renderer to your table.

How to select a specific cell in a JTable?
Hi there,
in a JTable, I would like to select a specific cell (to highlight it) from a JButton.
Here a sample code...
Who could help me to fill it?
import java.util.*;
import javax.swing.*;
import javax.swing.table.*;
import java.awt.*;
import java.awt.event.*;
public class TableSelection{
public static void main (String args[]) {
JFrame frame = new MyFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.show();
class MyFrame extends JFrame{
public MyFrame(){
setTitle("TableSelection");
setSize(WIDTH,HEIGHT);
DefaultTableModel myModel = new DefaultTableModel(2,2);
JTable myTable = new JTable(myModel);
myTable.setCellSelectionEnabled(true);
JButton button00 = new JButton("select 0,0");
button00.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent event){
System.out.println("selection of cell (0,0)");
//--- what code is required to select the cell(0,0)?
JButton button11 = new JButton("select 1,1");
button11.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent event){
System.out.println("selection of cell (1,1)");
//--- what code is required to select the cell(1,1)?
Box myBox = new Box(BoxLayout.Y_AXIS);
myBox.add(new JScrollPane(myTable));
myBox.add(button00);
myBox.add(button11);
getContentPane().add(myBox, BorderLayout.CENTER);
private static final int WIDTH=200;
private static final int HEIGHT=200;
}Thanks a lot for your help.
DenisUse the addColumnSelectionInterval(int index1, int index2)method ~ http://java.sun.com/j2se/1.4/docs/api/javax/swing/JTable.html#addColumnSelectionInterval(int,%20int)
and the addRowSelectionInterval(int index1, int index2) method ~ http://java.sun.com/j2se/1.4/docs/api/javax/swing/JTable.html#addRowSelectionInterval(int,%20int)
Hope that helped.

Create a JTable based on an ArrayList containing instances of a class.
I have a class, IncomeBudgetItem, instances of which are contained in an ArrayList. I would like to create a JTable, based on this ArrayList. One variable is a string, while others are type double. Not all variables are to appear in the JTable.
The internal logic of my program is already working. And my GUI is largely constructed. I'm just not sure how to make them talk to each other. The actually creation of the JTable is my biggest problem right now.import java.awt.Dimension;

URGENT HELP NEEDED FOR JTABLE PROBLEM!!!!!!!!!!!!!!!!!
firstly i made a jtable to adds and deletes rows and passes the the data to the table model from some textfields. then i wanted to add a tablemoselistener method in order to change the value in the columns 1,2,3,4 and set the result of them in the column 5. when i added that portion of code the buttons that added and deleted rows had problems to function correctly..they dont work at all..can somebody have a look in my code and see wot is wrong..thanx in advance..
below follows the code..sorry for the mesh of the code..you can use and run the code and notice the problem when you press the add button..also if you want delete the TableChanged method to see that the add button works perfect.

}There are too many mistakes in your program. It looks like you are new to java.
Your add and delete row buttons are not working because you haven't registered your action listener with these buttons.
I have modifide your code and now it works fine. Just put some validation code for the textboxes becuase it throws exception when user presses add button without entering anything.
Here is the updated code: Do the diff and u will know my changes

Can not show the JCheckBox in JTable cell
I want to place a JCheckBox in one JTable cell, i do as below:
i want the column "d" be a check box which indicates "true" or "false".
String[] columnNames = {"a","b","c","d"};
Object[][] rowData = {{"", "", "", Boolean.FALSE}};
tableModel = new DefaultTableModel(rowData, columnNames);
dataTable = new JTable(tableModel);
dataTable.getColumnModel().getColumn(3).setCellEditor(new DefaultCellEditor(new JCheckBox()));
But when i run it, the "d" column show the string "false" or "true", not the check box i wanted.
I do not understand it, can you help me?
Thank you very much!
coral9527Do not use DefaultTableModel, create your own table model and you should implement the method
getColumnClass to display the boolean as checkbox ...
I hope the following colde snippet helps you :
class MyModel extends AbstractTableModel {
private String[] columnNames = {"c1",
"c2"};
public Object[][] data ={{Boolean.valueOf(true),"c1d1"}};
public int getColumnCount() {
//System.out.println("Calling getColumnCount");
return columnNames.length;
public int getRowCount() {
//System.out.println("Calling row count");
return data.length;
public String getColumnName(int col) {
return columnNames[col];
public Object getValueAt(int row, int col) {
return data[row][col];
* JTable uses this method to determine the default renderer/
* editor for each cell. If we didn't implement this method,
* then the last column would contain text ("true"/"false"),
* rather than a check box.
public Class getColumnClass(int c) {
return getValueAt(0, c).getClass();
* Don't need to implement this method unless your table's
* editable.
public boolean isCellEditable(int row, int col) {
//Note that the data/cell address is constant,
//no matter where the cell appears onscreen.
return true;
* Don't need to implement this method unless your table's
* data can change.
public void setValueAt(Object value, int row, int col) {
data[row][col] = value;
fireTableCellUpdated(row, col); -

I think you need to change your loop to look something like this:
while(rs.next())
Vector row = new Vector();
row.addElement( rs.getString("start_date") );
row.addElement( rs.getString("end_date") );
row.addElement( rs.getString("display_start") );
row.addElement( rs.getString("display_end") );
row.addElement( rs.getString("short_desc") );
row.addElement( rs.getString("long_desc") );
data.addElement( row );
} Then remove your data.addElement() statements found outside the loop.
