JTABLE - FocusEvent on CelEditor!
Hi, I�m have a little problem: when im editing a cell in jtable and then i click in a button, the cellEditor do not do the event to update my TableModel, resuming: its like i did not have typed anything in table!
I really need help... i guess that its missing some focusEvent, like lostFOcusEvent in CellEditor, then when exit the celleditor (do not passing by the jTable, going right away to the Button) the celleditor fire the fireEditingStopped() event.
I just have no ideia how to do it....
Ice
Are you calling stopCellEditing()?
On the action of the button try doing this.
row = table.getEditingRow();
col = table.getEditingColumn();
if (row != -1 && col != -1)
table.getCellEditor(row,col).stopCellEditing();
Hope this helps...

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.

Tab and back-tab out of a JTable
Hi There,
I have been working for some time on improving the default behaviour of the tab key within editable JTables. It largely works as required now, but I'm stuck on getting back-tab to leave the table if on row 0, col 0. I register tab and back-tab action in the table's ActionMap that looks like this:
class TabAction extends AbstractAction {
public void actionPerformed(ActionEvent e) {
if (getRowCount() > 0) {
int row = getSelectedRow();
int column = getSelectedColumn();
if (row < 0 || column < 0) {
row = 0;
column = 0;
do {
if (++column >= getColumnCount()) {
row++;
column = 0;
} while (row < getRowCount() && ! isCellTabbable(row, column));
if (row < getRowCount()) {
changeSelection(row, column, false, false);
} else {
clearSelection();
transferFocus();
} else {
transferFocus();
class BackTabAction extends AbstractAction {
public void actionPerformed(ActionEvent e) {
if (getRowCount() > 0) {
int row = getSelectedRow();
int column = getSelectedColumn();
if (row < 0 || column < 0) {
row = getRowCount() - 1;
column = getColumnCount() - 1;
do {
if (--column < 0) {
row--;
column = getColumnCount() - 1;
} while (row >= 0 && ! isCellTabbable(row, column));
if (row >= 0) {
changeSelection(row, column, false, false);
} else {
clearSelection();
transferFocusBackward();
KeyboardFocusManager fm = KeyboardFocusManager.getCurrentKeyboardFocusManager();
// fm.upFocusCycle(BTTTable_Editable.this);
// fm.focusPreviousComponent(BTTTable_Editable.this);
} else {
// transferFocusBackward();
// KeyboardFocusManager fm = KeyboardFocusManager.getCurrentKeyboardFocusManager();
// fm.upFocusCycle(BTTTable_Editable.this);
// fm.focusPreviousComponent(BTTTable_Editable.this);
}transferFocus() to go to the next screen component works fine - as long as I callsetFocusTraversalPolicyProvider(true); when I create the JTable.
But the backward traversal just doesn't work - instead it does nothing the first time you press back-tab on row 0 col 0, then if you press it again, focus goes onto the last row/col of the table.
As an alternative, I thought maybe I could call the Ctrl-back-tab action, but I can't find that registered in the action map - can anyone tell me how ctrl-back-tab is called and whether I can call that code directly?
Any ideas?
Thanks,
TimWhere's the rest of your code? What good does posting
the Actions do if we can't execute your code and see
how you've installed the Actions on the table? Who
knows where the mistake is. It may be in the posted
code or it may be in some other code.Well I assume the Action is registered okay because back-tab within the table works fine, and in fact using a debugger I can see that the focus request code (transferFocusBackward) is being called at the right time. I followed it into that code and it appears that it is picking up the tableCellEditor as the "previous" component which is "why" it isn't working right - not that that helps me to fix it.

}I thought it might be the focusGained() code, but commenting that out makes no difference.
And here is the code I would use to go to the
previous component:
KeyboardFocusManager.getCurrentKeyboardFocusManager().
focusPreviousComponent();I tried that too, as you can see from my original post. It gives the same answer.
So the big question is why does the FocusManager think that the "previous" field to the table is an editor component within the table?

How do I get Integer in JTable cell to be selected when edit using keyboard
I have some cells in a JTable, when I double-click on the cell to edit it the current value (if any) is selected and is replaced by any value I enter, which is the behaviour I want. But when I use the keyboard to navigate to the cell and start editing, new values are added to the end of the current value which is not what I want.
I have created my own IntegerCellEditor (see below) and added a focus event or the textfield used when editing to select all the current text but it has no effect, any ideas please ?
public class IntegerCellEditor extends DefaultCellEditor
public IntegerCellEditor( JTextField textfield )
super( textfield );
//Ensure old value is always selected, when start editing
((JTextField)getComponent()).addFocusListener(new FocusAdapter()
public void focusGained(FocusEvent fe){
((JTextField)getComponent()).selectAll();
((JTextField)getComponent()).setHorizontalAlignment(JTextField.RIGHT);
* Return as Integer (because delegate converts values to Strings).
public Object getCellEditorValue()
return Integer.valueOf((String)delegate.getCellEditorValue());
}But when I use the keyboard to navigate to the cell and start editing,
new values are added to the end of the current value which is not what I want.How does the use know that typing will replace the text and not append? Usually if text is to be deleted, it is highlighted to give the user a visual cue.
Here is a renderer that does this, in case your interested:

How to get name of a Component retuned by FocusEvent.getOppositeComponent()
Hi,
I have three instances of JTable named table1, table2, table3 and one button. For the button I have FocusListener which listens to focusGained event. The FocusEvent enables me to get the Component which has lost the focus by e.getOppositeComponent(). Now my question: how can I understand which instance is that component table1, table2, or table3? getName(), getAccessibleContext().getAccessibleName() return nulls. I SIMPLY WANT TO KNOW WHICH TABLE LOST FOCUS WHEN BUTTON WAS PRESSED.
Thanksif you have the object use if (component instanceof table1) .....

JTable JCombox popup on click in table cell
What is the recommended way of making a JComboBox that is in a JTable cell popup when the user clicks once anywhere in the cell?
The popup is actually a calendar that works fine if the user clicks on the spot where the button shows up in the cell but sets the focus in the text box of the JComboBox is the click is anywhere else in the cell and the popup doesn't sho in that case. To get to the popup requires a click on the button.import java.awt.*;

JTable custom cell editor losing focus
This is a followup to Re: Tutorial on AWT/Swing control flow wherein I ask for pointers to help me understand the source of focus-loss behaviour in my JTable's custom cell editor.
I have done some more investigations and it turns out that the focus loss is a more general problem with custom cell editors which call other windows. Even the color-picker demo in the JTable tutorial at http://download.oracle.com/javase/tutorial/uiswing/examples/components/index.html#TableDialogEditDemo has this problem, IF you add a text field or two to the layout BEFORE the table. The only reason the table in the demo doesn't lose the focus when the color-picker comes out is because the table is the only thing in the window!
Here is the demo code, augmented with two text fields, which are admittedly ugly here but which serve the desired purpose:

}When you come back from choosing a color, tf1 is given the focus, instead of the table. This is because bringing the color picker window to the front causes a focus lost event for the cell editor component; it's temporary, as it should be, so why on earth is the system losing track of who has focus in the window??
I see the following in Window#getMostRecentFocusOwner():
public Component getMostRecentFocusOwner()
if (isFocused())
return getFocusOwner();
else
Component mostRecent =
KeyboardFocusManager.getMostRecentFocusOwner(this);
if (mostRecent != null)
return mostRecent;
else
return (isFocusableWindow())
? getFocusTraversalPolicy().getInitialComponent(this)
: null;
}My app has a custom focus traversal policy, so I'm able to see who is being called, and indeed, getInitialComponent() is being called. Clearly, the KeyboardFocusManager is actually losing track of the fact that the table was focussed at the point where control was transferred to the color picker! This strikes me as completely unreasonable, especially since, as noted, this is a temporary focus loss event, not a permanent one.
I'd be grateful for any wisdom in solving this, since similar behaviour to this little demo -- without focus loss, naturally -- is an essential part of my application.Looks like it is because the 'restore-focus-to-previous-after-modal-dialog-close' is in a later event than when the control returns to the action performed (which I guess makes sense: it continues the action event handler and the focus events are handled later, but I needed two chained invoke laters so it might also be that the OS events comes later).
The following works for me (in the actionPerformed edited):
// create the dialog here so it is correctly parented
// (otherwise sometimes OK button not correctly the default button)
dialog = JColorChooser.createDialog(button, "Pick a Color", true, //modal
colorChooser, this, //OK button handler
null); //no CANCEL button handler
//The user has clicked the cell, so bring up the dialog.
button.setBackground(currentColor);
colorChooser.setColor(currentColor);
button.addFocusListener(new FocusListener() {
@Override
public void focusLost(FocusEvent e) {}
@Override
public void focusGained(FocusEvent e) {
// dialog closed and focus restored
button.removeFocusListener(this);
fireEditingStopped();
dialog.setVisible(true);but a simpler request might be better (althoug I still need an invoke later):
// rest as before except the FocusListener
dialog.setVisible(true);
button.requestFocusInWindow();
EventQueue.invokeLater(new Runnable() {
public void run() {
fireEditingStopped();
});And a quick fix to the renderer so you can actualy see the focus on it:
if(hasFocus) {
Border border = DefaultLookup.getBorder(this, ui, "Table.focusCellHighlightBorder");
setBorder(BorderFactory.createCompoundBorder(
border, BorderFactory.createMatteBorder(1, 4, 1, 4,
((MatteBorder) getBorder()).getMatteColor())));
} -
I've noticed one annoying thing about JTable when running under Windows L&F. Namely, a table without focus renders its selection in the same color as a table with a focus. This can get really annoying especially with windows where containing more than one jtable.
Is there an good way of telling JTable to use a different color for selection when it doesn't have the focus?thanks, that worked. here's what i ended up donig:
addFocusListener(new FocusListener() {
private Color selectionBackground = getSelectionBackground();
private Color selectionForeground = getSelectionForeground();
public void focusGained(FocusEvent e) {
setSelectionForeground(selectionForeground);
setSelectionBackground(selectionBackground);
public void focusLost(FocusEvent e) {
if( !e.isTemporary()) {
setSelectionForeground(UIManager.getColor("inactiveCaptionText"));
setSelectionBackground(UIManager.getColor("inactiveCaption"));
});not too sure if inactiveCaption* is the best key to use, but I couldn't find anything better. Any ideas?
Thanks

Preventing JTree updates from uncompleted JTable edits
Hello there!!
I have an applet that displays an xml file in a JTree. Each node of the table represents specific elements of the xml file (some are not displayed by design). Also on the applet is a JTable that updates the displayed information depending on what node of the tree is clicked. The information displayed in the table includes names and values of attributes and names and values of xml elements not displayed in the JTree.
I can edit values in the table and update that tree effectively, so that is not a problem.
The problem I have is that if the user enters a value in the table, does not press enter and then clicks on another tree node, the entered value is copied into the new tree node. I would like to ignore all values if the user does not specifically press enter.
I have seen some code examples in previous posts that partially work, but can't get the entered values to be totally ignored.
I'm currently using the following code to handle the 'didn't press enter' bug.
table.getEditorComponent().addFocusListener(
new java.awt.event.FocusListener(){
public void focusGained(java.awt.event.FocusEvent e) {}
public void focusLost(java.awt.event.FocusEvent e){
if ( table.getEditingRow() > -1 &&
table.getEditingColumn() > -1 ){
((javax.swing.DefaultCellEditor)table.getCellEditor()).stopCellEditing();
});So my question is: How do I prevent the value entered in the table cell from being copied to the newly clicked on tree node? Any assistance would be great.
Thanks (even just for reading!)
Simon
PS. When are we going to see the back of the stupid censorship in this forum?Not too sure if this will help but here goes...
Normally in a JTable, editing is automatically stopped when the enter key is pressed so there is no need to do anything special there. If you don't want editing to stop when the mouse is clicked elsewhere in the table, what you should do is call cancelEditing() instead of stopEditing() in your focusLost method.

Tab Traversal problem in JTable
Hi all,
I am having a requirement in my current project to traverse across the cells of a JTable. Some of the cells were set CustomCelleditor(mainly textfield).
I have gone through the threads in this forum and tried a code snippet which is now highlighting the text on tab traversal. But there are 2 problems with which I am facing with :-
1. I need to press tab twice to move to the next cell(one is stopping cell editing and the other is to traverse to the next cell).
2. When I moved from cell 1 to cell2 using tab and then click on cell1, the text is not getting highlighted.
Please help me in resolving these issues ?
The code I tried includes :-
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.border.*;
import javax.swing.table.*;
import javax.swing.text.*;
public class TableSelectAll extends JFrame{
JTable table;
public TableSelectAll() {
Object[][] data = { {"1", "A"}, {"2", "B"}, {"3", "C"}, {"4", "D"} };
String[] columnNames = {"Number","Letter"};
DefaultTableModel model = new DefaultTableModel(data, columnNames);
table = new JTable(model) {
public void changeSelection(int row, int column, boolean toggle,
boolean extend) {
super.changeSelection(row, column, toggle, extend);
SwingUtilities.invokeLater( new Runnable(){
public void run() {
table.dispatchEvent(new KeyEvent( table, KeyEvent.KEY_PRESSED,
0,
0,
KeyEvent.VK_F2,

JScrollPane scrollPane = new JScrollPane( table );
getContentPane().add( scrollPane );
MyCellEditor dce = new MyCellEditor( new SelectAllEditor() );
dce.setClickCountToStart( 1 );
table.setDefaultEditor(Object.class, dce );

}Hello Ronnie,
this is a nice little piece of code. ;-)
No chance of reducing it a little bit just to show the problem?
And what about making it at least to compile error free? (Just tried on 1.5_06)
Also place tags around to make it more readable.

JTable's setValueAt() function -URGENT please help!!!
I am using a subclass of the DefaultTableModel for my JTable. The data is in the form of a Vector of vectors. I am catching user input (editing) by implementing the setValueAt() function. The table consists of 1 row, and 4 columns (thats a required limitation). When I edit(change) only one cell of the table, and dont tab out of the cell, I see that the setValueAt() function is not being called, and the model is not being updated. But when I change the cell value and tab out of the cell to the next cell, the setValueAt() function is being called.
How can I force the setValueAt() function to be called without tabbing out of the edited cell. I need to implement this feature as a user can change a single cell and click the "save" button.
here is the setValueAt() function implementation.. Could it be that I might have implemented this in error or need to implement some other methods? Any help/pointers will be greatly appreaciated.
public void setValueAt(Object value, int row, int col)
String cellValue = "";
if (value instanceof String)
cellValue = (String)value;
Vector tmp = (Vector)dataVector.elementAt(row);
tmp.setElementAt(cellValue,col);
fireTableCellUpdated(row,col);
Thank You in advanceSeems to me that the problem is to do with when setValueAt() gets called.
Sounds like you want it to be called when the Cell's editor loses focus.
One solution would be something like the following to ensure editing stops when focus is lost.
There may be other less complicated solutions, but this one should work !
class MyEditor extends AbstractCellEditor implements TableCellEditor {
public MyEditor() {
this.text = new JTextField();
this.text.addFocusListener(new FocusListener() {
public void focusGained(FocusEvent e) {
public void focusLost(FocusEvent e) {
stopCellEditing();
public Component getTableCellEditorComponent(JTable table, Object value,
boolean isselected, int row, int col) {
this.text.setText((String)value);
return this.text;
public Object getCellEditorValue() {
return this.text.getText();
private JTextField text;
table.setDefaultEditor(String.class, new MyEditor()); -
JTable row deletion deleting valuable information --need HELP
Hi Experts and Java Programmers,
I am posting the code that works 99% of the time. It basically creates a JTable and has row insertion and row deletion methods. The row insertion works fine. However, when a row N is deleted it causes the loss of data in the row N+1's cell in whichever cell the cursor is blinking. In other words, when cursor is in cell M of row N, row deletion sets the cell M of row N+1 to blank. So if the cursor is on the 2nd cell of 1st row and if 1st row is deleted, the data in the 2nd cell of 2nd row (now moved to 1st row) is lost.
Thanks for your help.
Murthy
