How to add JTextArea in JTable

Hi..
I want to add JTextArea in my table in one of the column of JTable. I have already written a code which implements TablecellEditor and TableCellRenderer. I have already succeeded to set textarea in one cell for multiple line but when i go to another cell my previous value disappears. Can anybody tell me the solution.

I think the reason that this is happening, is that you have to override the setValue method in TableModel, inorder for the value to be displayed correctly.
Another thing.
I too am trying to implement a textarea as one of the cells in a col.
But the problem is that when I create my celleditor extends TextArea and implements TableCellEditor, and compile it says that all eventLsiteners are already implemented .
And if I just extend the AbstractCellEditor, and return it in the method getCellEditor, it says incompatible types.
Can you tell me how to implement a CustomCellEditor
Thanks,

How to add data into JTable

How can I add data into JTable, for instance ("Mike", "Gooler", 21).

How can I add data into JTable, for instance ("Mike",
"Gooler", 21).You will have very good results if you segregate out the table model as a seperate user class and provide a method to add a row there. In fact, if you use the table to reflect a database table you can add the row inplace using the existing cursor. I believe it's TableExample2 in the jdk\demo\jfc\TableExamples that has a very good example of this.

How to add events in JTable fields

Hello friends i m working with file transfer client server project in my college.In my client part i have used JTable with AbstractTableModel.
In my JTable it list the current directory files and directories under current directory .
now how can i add events to the the directories that it shows on JTable so that when i click on directory it displays files under that selected directory.
can anyone help me in that.
I will send you my code for that project if anyone can help me.
please help me to do that

You can handle row selections with selection listener but if you want to handle double clicks you can use something similar to this:
table.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e)
int column = table.columnAtPoint(e.getPoint());
int row = table.rowAtPoint(e.getPoint());
Object cellValue = table.getValueAt(row, column);
// Insert files below clicked row
});Please, be more patient in the future -you would probably get an answer if you just posted to any of these two forums.

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.

How to add Chekbox in Jtable?

I am working on Swing application and my requirement is add new column that dispay the checkboxes, so user have the access to check/uncheck row for further process.
In application 3 tabbedpanes are there & in the 3rd tabbedpane table data is displaying.
//Code snippet
public class AIProductPropertiesUI
private productsTablemodel productmodel = null;
private String [] pNames = {"select","type","name","revision","marketing","relationship"};
public JPanel getMiscPanel()
productmodel= new productsTablemodel();
table = new JTable(productmodel);
protected class productsTablemodel extends AbstractTableModel
Vector productDetails ;
productsTablemodel()
productDetails = model.getProductDetails();
headerNames = model.getLabelNameMapping();
public Object getValueAt(int rowIndex, int columnIndex)
if (productDetails.size()>0)
Hashtable ht = (Hashtable) productDetails.get(rowIndex);
//ht contains the list of values for all the column as in pNames[].
// dynamic value for Select column is ""(blank string)
String str = "" ;
if(ht.containsKey(pNames[columnIndex]))
str = (String) ht.get(pNames[columnIndex]);
return str;
}else{
return null;
I tried following ways-
1)if(column==0)
return new JCheckBox("str",true);
here output is dispaying complete details of Checkbox
/* output for checkbox cell is --- javax.swing.JCheckBox[,0,0,0x0,invalid,alignmentX=0.0,alignmentY=0.5,
border=javax.swing.plaf.BorderUIResource$CompoundBorderUIResource@b1b4c3,flags=296,maximumSize=,minimumSize=,preferredSize=,defaultIcon=,

pressedIcon=,rolloverEnabled=true,rolloverIcon=,rolloverSelectedIcon=,selectedIcon=,text=str]*/
2)overiding public Class getColumnClass(int column)
if(column==0)
return Class.forName("java.lang.Boolean");
till this point its working fine... but in above code method public Object getValueAt(int rowIndex, int columnIndex)
I am checking if(Column==0)
return Class.forName("java.lang.Boolean");
here it is throwing ClassCastException.. java.lang.Class cannot be cast to java.lang.Boolean
Please provide me solution aas soon as possible...coz from past 2 days i m stucking on this and due to this not able to move ahead on my application development.
Thanks in Advance

HOW TO ADD COLORS TO JTABLE ROWS??

I want to change the colors of alternate rows in my JTable. I am doing so using CellRenderer, but then I am not able to view the selected rows.
tell me how can I change the row color as well as a selected row should be identifiable from others, as ordinary JTable.
thanks

Hi,
try this:
define your own DefaultTableCellRenderer like this:
class MyRenderer extends DefaultTableCellRenderer {
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus, int row, int column){
super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
if (isSelected) setBackground( Color.anyColor );
return this;
Hope it helps!

How to add unicode in jtables?

Well basically the name of the topic is the question. If you could show it directly in the code below that would be really great. Thanks.
import javax.swing.*;
public class TestUnicode extends JFrame {
     JTable table;
     String[] names = {"Name"};
     String[][] data = {{"GBP: \00A3"}, {"EUR: \20AC"}};
     public TestUnicode() {
          setTable();
          getContentPane().add(new JScrollPane(table));
          setSize(300, 300);
          setLocationRelativeTo(null);
          setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          setVisible(true);
     private void setTable() {
          table = new JTable(data, names);
     public static void main(String args[]) {
          new TestUnicode();
}

Add a lowercase "u" (for unicode) after your slashes: \u20AC.

How to add image in jtable header using 'Default table model'

Hi,
I created a table using "DefaultTableModel".
im able to add images in table cells but not in 'table header'.
i added inages in table by overriding "getColumnClass" of the DefaultTableModel.
But what to do for headers?
please help.
Thanks in advance.

The 'Java 5 tutorial' is really an outstanding oneI should note the the current tutorial on the Sun website has bee updated for Java 6. It contains updates to reflect the changes made in JDK6. Once of the changes is that sorting of tables is now supported directly which is why I needed to give you the link to the old tutorial.

              br.close();
             if possible give me some examples.
thank you.

For every row you need to create a new Vector and add the data to that Vector. Then the Vector is added to the TableModel.
If you add 6 items to the single Vector, then you will get 6 columns. So you need to create 6 Vectors and add a single item to each Vector and therefore you will end up with 6 rows with 1 column of data.

How to edit databases from JTable?

Why is my listener not working or why is it not implemented when I click the cells in the JTable and why is it not reflected into the JTable or into the console?
If this is Flash, Things can be done easily, but this is Java, and I dont know much about this language. I admit that I am new to this -intirely new.
PS:
When you have solved the problem, please notify me with the code that's changed
and please share it to others if you like so.

Why is my listener not working or why is it not implemented when I click the cells in the JTable and why is it not reflected into the JTable or into the console?What does happen when you click on the cells?
Does the ResultSetTableModel report the cells as editable? If not you will never get to edit their contents, and so the table's model won't change, and so the table model listener will never get invoked.
When you post code here use the code tags. Basically you put {code} at the start of your code and again at the end. That way the code will be readable.
Try to post minimal examples with which others can reproduce your problem. In this case "minimal" would involve removing or drastically simplifying a lot of the GUI stuff which is just noise. But "reproduce" would involve including the ResultSetTableModel.
When you have solved the problem, please notify me with the code that's changedAvoid this.
What you say here is quite possibly not what you mean. But, in any event, while there might be plenty of interest in helping with specific problems there will likely be none in writing your code. Your problem remains yours. But your solution and your code - prompted by whatever help you might recieve - will also be yours.
