JTable editCellAt
Hello Javaers,
I've a question for you regarding JTable edits - hoping to save some google time.
I've a JTable that currently accepts edits by careful overriding of the standard methods, isCellEditable, and by specifying
((DefaultCellEditor)table.getDefaultEditor(String.class)).setClickCountToStart(2); I'd like to disable click-edits at this point, and move the edit function to a context menu. How do I disable click editing?
Thanks!
Hey Camickr,
thanks for checking in as always. I actually discovered what was going on, it had me just as confused as you might have been by my post. I was firing the editCellAt from a JPopupMenu (as a context-menu action). I was puzzled when I saw that the edit wasn't occurring.
Turns out that it was indeed occurring, just that the disposal of the context menu probably momentarily stole focus from the edit, which was canceling the edit itself. I had to explicitly call dispose before initiating the action, and this solved my problem.
Thanks - I'll mark it as solved so that you can get some points.
Cheers!
Alex

JTable.editCellAt() not working
After using the editCellAt function of JTable I guess you should be able to just start typing in that cell (without any mouseclicks). (If this is not the case - then how to make that?). But it doesn't work! Is there something wrong with the code below? I want the last row's first column to be selected so that I can just start typing. But not even a cursor is visible.
tuplesTM.addRow(new Vector());
if (tuplesT.isCellEditable(tuplesTM.getRowCount() - 1, 0))
System.out.println("TRUE");
else
System.out.println("FALSE");
tuplesT.editCellAt(tuplesTM.getRowCount() - 1, 0);editCellAt(row, column) should work if
1) the cell (row, column) is editable, that is isCellEditable(row, column) returns true
2) there is an editor for the specified column
If all these conditions are true, try to add Vector(COLUMN_COUNT) instead of simple Vector(). -
Problem About Focus transfer in swing JTable Cell
I open a JDialog in KeyPressed Event of Cell of the JTable,when the JDialog closed, I cannot set the Focus to next Cell in my code. the focus was set on the ToolBar(I don't write it in my code).
key pressed
void this_keyPressed(KeyEvent e) {
String text = this.getText().trim();
if(e.getKeyCode()==10 && text.trim().length()>0)
wzdlg = new JDialog();
Dimension dlgSize = wzdlg.getPreferredSize();
wzdlg.setLocation(0,0);
wzdlg.setModal(true);
wzdlg.pack();
wzdlg.show();
//When JDialog Closed,Focus move to next cell
//table.editAt(0,1); //cannot getFocus
//following cannot get focus too
Component comp = ((DefaultCellEditor)table.getCellEditor(0,1)).getComponent();
if (comp instanceof javax.swing.JTextField) comp.requestFocus();
Why? How Can I do?Try calling prepareEditor after your editCellAt method. It would be like
JTable.editCellAt(row, col);
JTable.prepareEditor(theTextFieldComponent, row, col);
Here, the text field component would be from the component editor. I would recommend you holding a reference than doing a getComponent. But, both may work. -
JTable ArrayIndexOutOfBoundsException
Hi all,
Pleaaase help me solve this problem...
I get ArrayIndexOutOfBoundsException when I try to set some data in a JTable. I shall describe the scenario in detail.
There are 2 lines in a JTable. One with data, and one without data(which means a blank row, where the user is supposed to enter data).
The user clicks on a button(refresh). This clears off the empty rows, which leaves the JTable with only one row, the one with valid data.
Now the user clicks on another button(Save). This tries to position the cursor in the first row with the statement
editCellAt(0,0). Since the Jtable is having a valid entry here, I expect it to behave normally and proceed, after placing the mouse caret in the first row, first column.
But it throws a ArrayIndexOutOfBoundsException saying java.lang.ArrayIndexOutOfBoundsException: 2 >= 2.
I tried searching in this forum, posted also..but no help...
I am in jdk1.3.
Some postings here mention of something like reload() etc. in the tablemodel, but none of them are specific.
Any help will be HIGHLY appreciated,
Thanks...Here is the stackTrace

Hello everyone,
I have a JInternalFrame with a JTable with 12 columns (and other components). In the third column there is a ComboBox editable with AutoCompleteDecorator (package org.jdesktop.swingx.autocomplete.*) added with the following code:
comboBox=new JComboBox();//combobox editable
//filling the combobox with some data
AutoCompleteDecorator.decorate(comboBox);
this.cbce=new ComboBoxCellEditor(comboBox);
this.cbce.addCellEditorListener(this.tabCBKeyListener);
jtable.getColumnModel().getColumn(3).setCellEditor(cbce);The combobox editing works fine, but i have problems at 'editingStopped' event. In other words, when i press the TAB command, the focus exit from table going to a JTextField component, but this is an error because the focus must continue to the table in the 4th column!
I added this code (the CellEditorListener tabCBKeyListener), but doesn't function:
tabulatoreCBKeyListener=new CellEditorListener(){
public void editingStopped(ChangeEvent e){
jtable.editCellAt(jtable.getSelectedRow(), 4);
public void editingChanged(ChangeEvent e){
public void editingCanceled(ChangeEvent e){
};Can someone help me?

You do not need custom code to set the cell selection. By default the table will go to the next cell when you use the Tab key.The table will go to the next cell when i use the normal combo box in JTable, with the DefaultCellEditor.
If I use a combo with AutoCompleteDecorator and ComboBoxCellEditor it doesn't function...
I'm working both with normal JComboBox and AutoCompleteDecorator JComboBox.I verified more carefully and I've seen that you have reason in case the next cell is blank (without components).
If the next cell contains a combo box NOT editable, the tab exit from the table.
Now I rewrite the code:
//initialize and fill combobox and combobox2 - first is editable, the second is not editable
comboBox.setEditable(true);
AutoCompleteDecorator.decorate(comboBox);
this.cbce=new ComboBoxCellEditor(comboBox);
this.cbce.addCellEditorListener(this.tabulatoreCBKeyListener);
table.getColumnModel().getColumn(3).setCellEditor(cbce);
table.getColumnModel().getColumn(4).setCellEditor(new DefaultCellEditor(comboBox2)); -

NetBeans plugin broken in 3.1.0RC2
Hi,
I downloaded 3.1.0RC2 and installed it in my NetBeans/SunONE Studio IDE
and am having a problem.
It starts up OK, but when I go into Tools->Options and try to view the
JDO->Kodo Settings, I get an exception (included below).
I had a problem similar to this once before that you helped me work
through, so I tried the same thing you suggested then but it had no effect.
1. Disable the Kodo module.
2. Exit IDE.
3. Remove kodo-jdo.jar from the studio5_se/modules directory (was 3.0.3).
4. Restart the IDE. Check in Tools->Options...no more JDO.
5. Exit the IDE.
6. Copy the 3.1.0RC2 kodo-jdo.jar into the studio5_se/modules directory.
7. Restart the IDE.
Any ideas?
Thanks,
Bill

Yep, that was it. Actually, I noticed that there are actually five new
JARs in 3.1.0 that weren't in 3.0.3:
jline.jar
mx4j-admb.jar
mx4j-jmx.jar
mx4j-tools.jar
sqlline.jar
I also see that jakarta-commons-logging-1.0.3.jar & log4j-1.2.6.jar which
were in 3.0.3 are not in 3.1.0.
Are these differences explained in the release notes (I admit, I didn't
even look at them blush).
Thanks!

MouseMotionListener Problem (Java 5&6)
Hallo all,
I am sorry I cannot send any codes right now but I have a problem. I have several components in my application and what I want to do is that when my cursor moves from my JTable it must set the first cell (0,0) editable so that when I try to focus on that table via TAB it can focus the first cell. I try to do this via MouseMotionListener but I want to know how I can make it know that the cursor has left the component area. I hope you could understand my problem.A MouseListener has mouseEntered and mouseExited methods, so you can use those, however it is a separate issue whether you wish to give focus to the table when the mouse enters it. Reminds me of some X-windows window managers that can do that with top-level windows...
Anyway, may be you want to have a focus listener on the table and start cell editing when the table gains the focus (JTable.editCellAt()). You'll need to be careful when the editor component itself loses focus (when editing stops) as the table will gain it again at this time. May be check the component losing the focus to trap this case. -
EditCellAt() with mouseclick is not working for first row of the jtable
Hi All,
I have extended JTable.changeSelection() & editCellAt() methods to force the text to select when focus is brought to the cell.
I have a page which has both editable and non-editable columns. when I do a mouse click on FIRST ROW of the editable cell and type the value, The value is not displayed in the cell. when I click on any other editable field in the page, The typed value is displayed in the cell. In the first row of the cell, only the first attempt is not working. When I remove the editCellAt() call in changeSelection(), it works as expected.
But, If I reach the FIRST ROW editable cell using TAB key instead of Mouse click and type the value, its working fine.
Kindly suggest me what could be the problem in my code. I think something wrong in editcellat() or mouseclicked/released or focusgained in our versions of JTable or jtextfield.
Kindly let me know if you need any more functions of my version of implementation.
Thanks In advance.
My JTable Version of editCellAt:
public boolean editCellAt(int row, int column, EventObject e) {
try {
if (getCellEditor() != null && !getCellEditor().stopCellEditing()) {
return false;
if (!isCellEditable(row, column)) {
return false;

Java.awt.IllegalComponentStateException in JTable
Hi folks,
I am trying to write a JTable cell validation. Input data in a cell, if failure, prompt message and set focus & editing back to the cell. I've tried InputVerifier() but it doesn't work since I can easily use the mouse click to shift to other cells in the same table.
What I am trying to do now is to define my DefaultCellEditor. I record the row & index position when getting focus. In the lost focus event, do the validation and set the focus & editing back if failure. Seems it works fine. However, when I randomly click different cells in the table quickly. It prompts:
"java.awt.IllegalComponentStateException: component must be showing on the screen to determine its location"

I have an extended JComboBox which is meant to display its information only. Thus it
- does not allow any selection
- shows the first item of the list in the TextField only and not once more in the listI don't see the need for duplicating the model and using a popup menu listener.

Mouselistner is not working with jtable in the browser
Hi
I am having a problem with jTable.
I added a mouselistener to table header to sort table but when i run that applet from my netbean ide it works fine but when i run that applet in my browser it doesn't work, i have tested, its not even generate mouseclick event .Please help me guys.
I call this function after calling initComponents() method of JApplet.
public void setTableAction()
//set mouselistener to sort table on click of table header
final JTableHeader head= jTable1.getTableHeader();
head.addMouseListener(new java.awt.event.MouseAdapter()
public void mouseClicked(java.awt.event.MouseEvent evt)
Vector data= ((DefaultTableModel)jTable1.getModel ()).getDataVector();
sortTable(data, head.columnAtPoint(evt.getPoint()));
//set action map to change the default action performed for enter key pressed
InputMap imap = jTable1.getInputMap(JTable.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT);
KeyStroke enterKey = KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0);
KeyStroke tabKey = KeyStroke.getKeyStroke(KeyEvent.VK_TAB, 0);
final Action oldAction= jTable1.getActionMap().get(imap.get(tabKey)); // get map to set enter key.
imap.put(enterKey, "enter"); // set enter key
Action newAction = new AbstractAction(){
public void actionPerformed(ActionEvent e) {
oldAction.actionPerformed(e);
JTable table= (JTable)e.getSource();
table.changeSelection(0,0,false,false);
if(table.isCellEditable(0,0))
String sTemp= (String)table.getValueAt(0,0);
if(sTemp.length()>0) {
if(bRenewItem)
retrieveRcodeDetails("",sTemp);
else
processRCodeDetails(sTemp, e);
}else
table.editCellAt(0,0);
jTable1.getActionMap().put("enter", newAction);
jTable1.setPreferredScrollableViewportSize(jTable1.getPreferredSize());
}Hi,
I also am using the Bépo layout with an encrypted drive and encountered the same problem: the Return key does not work.
It seems to work fine if you use the fr-bepo-latin9 keymap.
# /etc/vconsole.conf
KEYMAP=fr-bepo-latin9
But I also looked at the files /usr/share/kbd/keymaps/i386/bepo/fr-bepo.map.gz and /usr/share/kbd/keymaps/i386/bepo/fr-bepo-latin9.map.gz (you can open gzipped files in vim directly). fr-bepo-latin9.map.gz defines keycode 28 (Return) but fr-bepo.map.gz does not.
I modified fr-bepo.map.gz:
# vim /usr/share/kbd/keymaps/i386/bepo/fr-bepo.map.gz # Append that line : "keycode 28 = Return".
# mkinitcpio -p linux # Rebuild the initramfs.
The Return key now works, but the Backspace (14, "Delete") and Shift (54) keys don’t work. I found that both the cf.map.gz (french canadian layout) and fr-bepo-latin9.map.gz files define those keycodes as well as other non-printing keys so I copied the following lines from fr-bepo-latin9.map.gz to fr-bepo.map.gz:
keycode 1 = Escape Escape
keycode 14 = Delete Delete
keycode 15 = Tab Tab
keycode 28 = Return
keycode 29 = Control
keycode 42 = Shift
keycode 54 = Shift
keycode 56 = Alt
keycode 58 = Caps_Lock
keycode 97 = Control
It works! Don’t forget to rebuild the initramfs after you change the keymap file.
# mkinitcpio -p linux
I will send a message to the kbd and bépo projects mailing lists and report back. -

Intercepting editing start and stop/cancel in a JTable
Hi,
I've been seaching the forum for days but could not find anything that solved my problem.
Problem:
I'm writing a multiclient server. The data of the server is displayed in a JTable. The rows(cells) in the table is editable and to make sure no two clients edit the same row at the same time I've implemented a locking mechanism in the server and would like to lock a row whenever a user starts editing and release the lock when the user either stops or cancels editing.
The JTable is 'hooked up' with a TableModel class that I've written to handle the locking and notification of the lock and unlock events from the server.
I've tried a couple of things but non worked very good. It would be nice if the CellEditorListener implemented a startEditing but it does not so letting my model implement the interface was no good.
Any ideas? If anyone knows how to solve this, please reply
Yours, JohanPlaying around with some methods in JTable, and some minimal testing, I came up with:
table = new JTable(...)
private int editingRow = -1;
public boolean editCellAt(int row, int column, EventObject e)
boolean editingCell = super.editCellAt(row, column, e);
if (isEditing())
editingRow = row;
System.out.println("started");
return editingCell;
public void removeEditor()
if (isEditing())
editingRow = -1;
System.out.println("stopped");
super.removeEditor();
}; -
Using a JPanel as cell editor in JTable
I have a composite component (JPanel that contains a JTextField and a
JButton) that I would like to use as the a cell editor in a JTable.The JButton instantiates a UI editor component that I have designed. Example would be date editor for dates, tet editor for strings etc. This editor allows the user to select a date to populate the JTextField (the date may also be manually entered).
I have no problem with the rendering of the component within the table.However, I would like for the JTextField embedded within the JPanel to receive focus and a visible caret, when using the tab key to navigate to the cell. After reading through some of the posts here , I was able to transfer the focus. But I dont see a visible caret. I am unable to edit. I have to click on the text box and then start typing. Its a great pain in the ass.
I have a custom designed table and custom designed editor. Code is attached...
<pre>
protected boolean processKeyBinding(KeyStroke ks, KeyEvent e,int condition, boolean pressed) {
final int selRow = getSelectedRow();
final int rowCount = getRowCount();
final int selCol = getSelectedColumn();
final EventObject obj = (EventObject) e;
if (selRow == -1) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
changeSelection(0, 1, false, false);
editCellAt(0, 1, obj);
boolean isSelected = false;
if ((ks == KeyStroke.getKeyStroke(KeyEvent.VK_TAB,0)) ||
(ks == KeyStroke.getKeyStroke(KeyEvent.VK_ENTER,0))) {
if (selCol == 1) {
isSelected= getCellEditor(selRow,selCol).stopCellEditing();
targetRow = (selRow + 1) % rowCount;
SwingUtilities.invokeLater(new Runnable() {
public void run() {
if (editCellAt(targetRow, 1, obj)) {
changeSelection(targetRow, 1, false, false);
getComponentAt(targetRow, 1).requestFocus();
} else {
getCellEditor(selRow, selCol).shouldSelectCell(obj);
return super.processKeyBinding(ks,e,condition,pressed);
</pre>
Relevant code of my custom editor is below....
public Component getTableCellEditorComponent(JTable table,
Object value, boolean isSelected, int row, int column) {
lastEditedRow = row;
lastEditedCol = column;
lastEditedTable = table;
lastEditedValue = value;
val = value;
((JTextField)editorComponent).
setText(val == null ? "" : val.toString());
setClickCountToStart(1);
if (value instanceof CycCollectionChooserModel) {
String collection = ((CycCollectionChooserModel)value).
getCollection().cyclify();
button.setVisible(EditorForCollectionMap.hasUIEditor(collection));
button.setMargin (new Insets (1,1,1,1));
button.setIconTextGap(0);
buttonListener.model = (CycCollectionChooserModel)value;
buttonListener.rowIndex = row;
buttonListener.localTable = table;
return panel;
public boolean isCellEditable(EventObject evt) {
if (evt instanceof MouseEvent) {
int clickCount;
clickCount = 1;
return ((MouseEvent)evt).getClickCount() >= clickCount;
return super.isCellEditable(evt);
public boolean stopCellEditing() {
if (super.stopCellEditing()) {
final int targetRow = (lastEditedRow+1)%lastEditedTable.getRowCount();
SwingUtilities.invokeLater(new Runnable() {
public void run() {
lastEditedTable.changeSelection(targetRow, 1, false, false);
lastEditedTable.getComponentAt(targetRow, 1).requestFocus();
return true;
return false;
Does any one know why I am not able to see the caret? Any insights you have will be most welcome.
Thanks in advance,
Praveen.Almost solved the problem. Navigation through Tab key, up/ down arrow, Enter key works for text boxes. Navigation through Tab Key, Up/down arrow works for combo boxes. But for "Enter" key it doesnt. Changes in code ....
(I have added a key listener to my editor class)

How to capture the data entered in a textfield in a JTable
How to capture the data entered in a textfield present in a cell of a textfield or how to add listener to this textfield
A sample of my code is:
model = new GridDisplayTableModel(gridDisp,columnName,getRows(),getCols());
final ComboRenderer cRenderer = new ComboRenderer();
final TextFieldRenderer tRenderer = new TextFieldRenderer();
combo.addItem("one");
combo.addItem("two");
combo.addItem("three");
