JTable Cell text selection Problem.

I am using Tab key while navigating with the Cells.While focus reaches into a cell,the cell is selected but not the cell content.So I use BACKSPACE to delete each word of the cell.I want to Select a cell content(i.e. Text) when I am move Tab keys to select cells.Please help me..........,u may send a mail at [email protected]

Do u need this feature to the whole table or else for the perticular cell in the table?
Are you using your own renderer or editor to the perticular cell ?,
this issue is related to Renderer and Editor, so if i know your requirement , then only it is easy to implement.

Jtable - partial text selection

Hey all,
I have a read-only table.
Currently, when a user clicks on a cell, the whole cell is selected.
I want to allow the user to select only a partial text in the cell - mainly for copy purposes.
How can I achieve that?

The trick (with Swing) is that the JTable must be enabled and you must register a custom Tableeditor that prevents the string from changing:
public class SelectableTextTableTest {
    public static void main(String[] args) {
        DefaultTableModel notEditableModel = new DefaultTableModel(11, 5) {
            @Override
            public Object getValueAt(int row, int column) {
                return "Column " + column + " / Row " + row;
            @Override
            public boolean isCellEditable(int row, int column) {
                return false;
        JTable table = new JTable(notEditableModel) {
            @Override
            public boolean isCellEditable(int row, int column) {
                return true;
        JTextField textField = new JTextField();
        textField.setEditable(false);
        table.setDefaultEditor(Object.class, new DefaultCellEditor(textField));
        JOptionPane.showMessageDialog(null, table);

Text selection problem in linked containers

Hi,
I get a strange behavior on the selection of text in a textFlow with several linked containers (from the latest SVN version it seems).
The problem occurs on the following case: http://lafabrick.com/labz/tlfTest/ (source code enabled)
If I select some text in container D to A (or vice versa): display of text selection is correct.
The problems are:
- If I select some text in the containers B or C, and that I move the selection to the right or left: the container is moving ...
- If I select some text in the containers B or C, and that I move the selection to the up or down: the display of the selection is not normal (I have a "blinking selection")
TLF version : 502 (715519)
Regards
fabien

Hi Richard,
Would you like to said that this fixe is not present on the SVN (/trunk) ?
In this case it's of course a bad news for me: my app can't takes all benefits of TLF for now (and for MAX...).
But a good news for all ! It means that TLF is perhaps soon to release !
Thanks a lot.

Text selection problems in Pages on iPad

I use Pages on an iPad, and have recently been having problems with text selection. If I press the screen on a word, that word goes blue but I can't extend the blue area beyond the single word. Usually the document freezes. Sometimes I can unfreeze it by continuing to press, but I still can't select the area required. Select all works fine. I have tried the same operation in Documents 2, and initially I had the same problem, but then it started working as usual. Has anyone else had the same problem? Advice would be much appreciated.
Bob Sax

You probably have floating objects with text wrap on and are hammering away at returns, spaces and tabs to position text. The mix of objects and text are tucking in and around each other in somewhat unpredictable ways.
Cut the objects and paste them into the text to make them Inline and you might be able to position things more predictably.

JeditorPane text selection problem due to line feeds and carriage returns

Hi folks,
I have a jEditorPane (text/plain) that contains a document in which the user has highlighted some text. I want to pull the selected text from the pane, do some processing on it, and then put the altered text back in the same position.
First I get the starting and ending position of the highlighted text
int mySelStart = myJEditorPane.getSelectionStart();
int mySelEnd = myJEditorPane.getSelectionEnd();Then I get all the text from the pane and (in theory) strip out the portion the user highlighted
String myPaneText = myJEditorPane.getText();
String mySelectedText = myPaneText.substring(mySelStart,mySelEnd);But the text string in mySelectedText never matches what the user originally highlighted. The starting and ending positions are off by the number of carriage returns that proceed the highlighted text in the document. It appears that while in the jEditorPane Java treats the carriage return as one characters, but once the info is in the myPaneText field Java treats the carriage return as two characters.
Has anyone encountered this before? Am I doing something wrong? To fix the problem I'm looping through the entire document to find out how many carriage returns proceed the highlighted text, but there has to be an easier way.
Thanks

It appears that while in the jEditorPane Java treats the carriage return as one
characters, but once the info is in the myPaneText field Java treats the carriage
return as two characters.Correct on a Windows platform. Check out my posting here for a one line solution:

Cell border selection problem

I have a spreadsheet that is a week at a glance schedule for a dance school. There are three columns per day, each representing a different studio location. Each row represents a 15 minute block time. I have been trying to create a border for each class (class times vary from 45 minutes to 2 hours) while leaving the in-between lines blank. For each 45 minute class, I select the three cells in a column, scroll down the border selection tool and select the outside border icon, next select the type of line, then the weight, finally the color, and so on. Once I get about 50% done working my way across the spreadsheet, buggy things start to happen. For example, a horizontal line will extend across several columns, sometimes intersecting previously defined class blocks. If I try removing the errand lines, then all the frames that do require a border at that position get their border errased. I them have to go back to those cells to re-assign a border segment, but then the unwanted horizontal line will reappear in the blank cells again. Very frustrating. Also, in my opinion, there are some cell frame options that are missing in this program. I t would be nice to have a button to select the top and bottom of a frame or group of frames at the same time. At present, you have to first select the top border, format it, then the bottom border and format it. Same goes for left and tight border sections. You can't select the two outside edges to apply the same style/thickness/color. Excel's border formatting commands are much better in this regard.
Title was edited by: Host

Hi Jim,
I played around with the border options today and although I didn't have the borders going where they were not wanted I understand your frustration having to set either all four or just one border at a time.
Just as an option, would filling the sets of cells with a light colour for each class work better for you?

JTable cell Background Color problem

I overriden the table renderer and tried to chenge the color of only that row which has greater value in the third column. I coded the logic but it set the color of all the rows. The custom tablecellrendere code is as follows
      public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected,boolean hasFocus, int row, int column)
            cell = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
               if(vuti[0]==0)
                    //cell.setBackground(Color.pink);
                    vuti[0]=counter;
               else
                    if (counter>vuti[0] && !isSelected)
                      vuti[0]=counter;
                      cell.setBackground(Color.lightGray);
                  else if(counter<vuti[0])
                    cell.setBackground(Color.white);
            return cell;
      }

In the code that sets the background, you have a if - else (if - else if) structure. What's the default setting, when none of the 3 conditions are met?
And learn to indent your code correctly so that code blocks are readily apparent.

Selection Problem with JTable

Hello,
i have a selection problem with JTable. I want to allow only single cell selection and additionally limit the selection to the first column.
I preffered the style from MS Outlook Express where you can select the email accounts to edit.
It is a table like this:
Account name |   Type |   ...
--------------|---------|---------------------
Hotmail       |   POP3 |
GMX           |   IMAP |The selection should be only avaibable at 'Hotmail' or 'GMX' - not at 'POP3', 'IMAP' or as complete row selection.
Please help me!
Thanks.

How to select rows in the inner JTable rendered in an outer JTable cell

I have wrriten the following code for creating cell specific renderer - JTable rendered in a cell of a JTable.
table=new JTable(data,columnNames)
public TableCellRenderer getCellRenderer(int row, int column)
if ((row == 0) && (column == 0))
return new ColorRenderer();
else if((row == 1) && (column == 0))
return new ColorRenderer1();
else
return super.getCellRenderer(row, column);
ColorRenderer and ColorRenderer1 are two inner classes, which implement TableCellRenderer to draw inner JTable on the outer JTable cell, having 2 rows and 1 column each.
Now what is happening the above code keeps executing continously, that is the classes are being initialised continously, inner JTables are rendered (drawn) continously, and this makes the application slow after some time. It throws java.lang.OutOfMemoryException.
WHY IS IT SO??? I can't understand where's the bug..
Any advice please???
Moreover i want selections in inner tables and not on outer table, how can this be possible.
I am working on this since a long time but have not yet found a way out...

With your help i have overcome the problem of continous repeatition.
The major problem which I am facing is, in selecting rows in the inner rendered JTables.
I have added listener on outer JTable which select rows on the outer JTable, hence the complete inner JTable which being treated as a row, gets selected.
The thing is i need to select the rows of inner rendered JTables,not the outer JTable.
How to go about it??
I have even added listener to inner rendered JTables, but only first row of every table gets selected.
Please help....
Thanks in advance.

JTable custom cell editor focus problem

Hi I have created a JTable (using Java 1.4.2) and have three cell Editors, one is a JFormattedTextField, one is a JComboBox and one is a custom cell editor.
When I press tab I can select the cell with the JFormattedTextField and when I start typing the JFormattedTextField accepts my input and it is displayed in the cell. This is the type of behaviour I would like but it does not seem to work for my other 2 cell editors:
When I tab to the JComboBox cell I can see that the cell is selected but typing or using the arrow keys does not allow me to select a new value in the JComboBox. (I have also tried typing space or enter to activate the JComboBox whilst the cell is selected.) The only ways to select a new value at the moment is to first click on the cell with the mouse and then use the keyboard to select a new value. It is like the actual JComboBox is not receiving the focus? Does anyone know how to solve this problem?
I also seem to have the same problem with my custom cell editor. My custom editor is a JPanel which contains JFormattedTextField again I can tab to the cell and see that it is selected but to activate the JFormattedTextField I have to actually select it with the mouse.
I have been stuck on this for some time so if any one has any suggestions they would be much appreciated !

Cell contents selected on focus in JTable

I'm new to swing and trying to get the contents of a JTable cell to be selected when the cell receives focus. I've looked at the TableCellEditor interface and the like, but I just can't seem to get the hang of how it all fits together. Any hits would be appreciated. Thanks.

There are several ways to do this, but here is one to get you started:
First, subclass DefaultCellEditor. Here, I have duplicated all the constructors from DefaultCellEditor but only modified the one used for text.
I have added a inner class, FocusEventHandler, to capture the focus events. In the focusGained method is the code to do the selectAll. (I use the invokeLater so that the selectAll happens after pending events are complete. A mouse click might be interpreted by the text box to position the cursor, so we want the selectAll to happen after that.)
Then, in the constructor for text, I save the text box so the focusGained method knows which text box to selectAll for, register the event handler, and (optionally) change the ClickCountToStart.
public class NewDefaultCellEditor extends javax.swing.DefaultCellEditor {
javax.swing.JTextField saveTextField = null;
// Event handler
public class FocusEventHandler implements java.awt.event.FocusListener {
     public void focusGained(java.awt.event.FocusEvent e) {
          javax.swing.SwingUtilities.invokeLater(new Runnable () {public void run() {saveTextField.selectAll();}});
     public void focusLost(java.awt.event.FocusEvent e) {}
// Constructors
public NewDefaultCellEditor(javax.swing.JCheckBox checkBox) {
     super(checkBox);
public NewDefaultCellEditor(javax.swing.JComboBox comboBox) {
     super(comboBox);
public NewDefaultCellEditor(javax.swing.JTextField textField) {
     super(textField);
     saveTextField = textField; // save text field for later
     textField.addFocusListener(new FocusEventHandler()); // register event handler
     setClickCountToStart(1); // change # of mouse clicks to begin editing
}Now you just have to tell the table to use this Cell Editor. One way to do this is:
MyTable.getColumnModel().getColumn(0).setCellEditor(new NewDefaultCellEditor(new javax.swing.JTextField()));
(this sets the editor for column 0)

Custom JTable cell editor problem

I have a custom JTable cell editor which is a JPanel with 2 JtextFields, One for a name, the other for a data value. My problem lies in when the the cell is selected and then the user start typing. The JTextfield outline shows up, but there is no carat. I can only edit the cell when I click the mouse in it again. I have my isCellEditable method set to only allow editing on 2 mouse clicks, but I did try it with just returning true and had the same problem. Please help.
Code:
class cellValue {
String name;
String data;
Color nameColor;
Color dataColor;
Font font;
public cellValue(String n, String d, Color nC, Color dC, Font ff){
name = n;
data = d;
nameColor = nC;
dataColor = dC;
font = ff;
} //end class
public class TextFieldCellEditor extends JPanel implements TableCellRenderer, TableCellEditor{
private EventListenerList listenerList = new EventListenerList();
private ChangeEvent event = new ChangeEvent(this);
private cellValue s;
private int e_row=0;
private int e_col=0;
private JTextField ta;
private JTextField tb;
public TextFieldCellEditor() {
setLayout(new GridBagLayout());
ta = new JTextField();
tb = new JTextField();
tb.setHorizontalAlignment(SwingConstants.RIGHT);
add(ta, new GridBagConstraints(0,0,1,1,0.6,0.0,java.awt.GridBagConstraints.WEST,java.awt.GridBagConstraints.BOTH,new Insets(0,1,0,0),0,0));
add(new JLabel(" "),new GridBagConstraints(1,0,1,1,0.1,0.0,java.awt.GridBagConstraints.WEST,java.awt.GridBagConstraints.BOTH,new Insets(0,1,0,0),0,0));
add(tb, new GridBagConstraints(2,0,1,1,0.3,0.0,java.awt.GridBagConstraints.EAST,java.awt.GridBagConstraints.BOTH,new Insets(0,1,0,0),0,0));
} //end init
public Component getTableCellRendererComponent(JTable table, Object value,boolean isSelected,
boolean hasFocus,int row, int column) {
s = (cellValue)value;
e_row = row;
e_col = column;
ta.setText(s.name);
tb.setText(s.data);
ta.setFont(s.font);
tb.setFont(s.font);
ta.setForeground(s.nameColor);
tb.setForeground(s.dataColor);
setForeground(table.getForeground());
setBackground(table.getBackground());
ta.setBackground(table.getBackground());
tb.setBackground(table.getBackground());
ta.setCaretColor(Color.WHITE);
tb.setCaretColor(Color.WHITE);
return (JComponent)(this);
public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column) {
return (getTableCellRendererComponent(table, value,isSelected, true, row, column));
public boolean isCellEditable(EventObject e) {
if (e instanceof MouseEvent) {
return ((MouseEvent)e).getClickCount() >= 2;
} return true;
// return true;
public boolean shouldSelectCell(EventObject anEvent) {
return (true);
public void cancelCellEditing() {
public boolean stopCellEditing() {
fireEditingStopped();
return (true);
public Object getCellEditorValue() {
return (ta.getText());
public void addCellEditorListener(CellEditorListener l){
try {
SwingUtilities.invokeLater(
new Runnable() {
public void run() {requestFocus();}
} catch (Exception e) {};
listenerList.add(CellEditorListener.class, l);
public void removeCellEditorListener(CellEditorListener l) {
listenerList.remove(CellEditorListener.class, l);
protected void fireEditingStopped(){
Object[] listeners = listenerList.getListenerList();
for (int i = listeners.length - 2; i >= 0; i -= 2)
((CellEditorListener)listeners[i+1]).editingStopped(event);
protected void fireEditingCanceled() {
Object[] listeners = listenerList.getListenerList();
for (int i = listeners.length - 2; i >= 0; i -= 2)
((CellEditorListener)listeners[i+1]).editingCanceled(event);
} //end class

Thanks again for the repley.
I tried removing the celleditorlistener and using the setSurrenderFocusOnKeystroke, but it did not work. The textfield is editable;
I did change:
public void addCellEditorListener(CellEditorListener l){
try {
SwingUtilities.invokeLater(
new Runnable() {
public void run() {ta.requestFocus();}
} catch (Exception e) {};
listenerList.add(CellEditorListener.class, l);
}This allows the first textfield to request focus and this seems to work. But when I highlight a cell, then start typing, the first character I type puts me into the editor, but it is lost. Example:
I type hello
and get ello in the cell. Then when I press enter the input is excepted and the selection goes to the next cell, but I cannot move the Highlight cursor at all, seems locked. The only way I can continue to the next cell is to use the mouse.
You said you had a cell editor working. Would you care to share as an example. This is killing me to get this to work properly.
Thanks again
Dave

Problem in jtable cell

Hi
I am facing one problem. there is some data should be displayed in Jtable cell.
The thing is that the whole data shall be visible in the cell.. for this I am writing one renderer.. but I could not find the desire solution.. please check it out

Thanks

In summary, you have one or more columns for which the data must be wholly visible - correct? If you need all the columns to show the whole of their data, you are goinf to have to expand the table, otherwise you can expand a column with something like
myTable.getColumnModel().getColumn(whichever).setPreferredWidth(whatever);
