Table cells editing

I have a table with few rows and columns filled up with certain values. I edit a cell. Now if i get the DataVector of the table this edited value is not obtained. If I try clicking some other cell after editing then get the DataVector the edited value is obtained. Why is this??? Should I have any Listeners added?? Please reply in depth

Hi,
hmm ... it seems, that the editing progress was not finished in the first case. JTable updates an entry in the datamodel only if the editing process is finished. As long as you see the blinking cursor in this field, editing is in progress and you can avoid storing by pressing ESC - but when you TAB to another cell or click another cell, the editing process is finished and the data is updated in the datamodel.

Table cell editing

how to edit table cells ? i am trying it since 2 days. with different errors. it's throwing some null pointer exception.
public TableView getTableview() {
         TableView<Contact> fx2TableView = new TableView<Contact>();
         public TableColumn<String> firstNameCol = new TableColumn<String>("First Name");
        fx2TableView.setLayoutX(260);
        fx2TableView.setLayoutY(20);
        fx2TableView.setOnMouseClicked(new EventHandler<MouseEvent>() {
            public void handle(MouseEvent event) {
                   if(event.getClickCount()==2) {
                   System.out.println(fx2TableView.getEditingCell().getRow());
        AccountDb myTableData = new AccountDb();
        ObservableList<Contact> teamMembers = FXCollections.observableArrayList(myTableData.mymain());
        fx2TableView.getItems().clear();
        fx2TableView.setItems(teamMembers);
        firstNameCol.setDataRetriever(new Callback<CellDataFeatures<String>, String>() {
            public String call(CellDataFeatures<String> c) {
                return ((Contact) c.getValue()).getFirstName();
        TableColumn middleNameCol = new TableColumn("Middle Name");
        middleNameCol.setDataRetriever(new Callback<CellDataFeatures<String>, String>() {
            public String call(CellDataFeatures<String> c) {
                return ((Contact) c.getValue()).getMiddleName();
        TableColumn<String> lastNameCol = new TableColumn<String>("Last Name");
        lastNameCol.setDataRetriever(new Callback<CellDataFeatures<String>, String>() {
            public String call(CellDataFeatures<String> p) {
                return ((Contact) p.getValue()).getLastName();
        fx2TableView.getColumns().addAll(firstNameCol, middleNameCol, lastNameCol);
        return fx2TableView;
    }now i can see the data from table . how to edit it . i tried few statements to print a particular cell data.
by using
System.out.println(fx2TableView.getEditingCell().getRow()); or
                  fx2TableView.edit(fx2TableView.getColumns(fx2TableView.getEditingCell()));
               System.out.println(fx2TableView.getRowFactory().call(CellDataFeatures<String> c) {
                ((Contact)c.getValue()).getFirstName()));
             fx2TableView.getOnEditStart(new EventHandler<EditEvent>()) {
              public void handle(EditEvent e) {
                }); what to write ? i am totally lost . any example how to edit , save and cancel on tableview edit ?
Thanks.

Hello User you can easily modify your Table Cell . In context of your code I've made one sample editing cell for your 'first column'.
firstNameCol.setCellFactory(new Callback<TableColumn<String>,TableCell<String>>(){
            public TableCell<String> call(TableColumn<String> param) {
                final StackPane stack = new StackPane();
                final Label label = new Label("test");
                final TextBox box = new TextBox("test");
                box.setVisible(false);
                //adding children to stack z-index
                stack.getChildren().add(label);
                stack.getChildren().add(box);
                final TableCell cell = new TableCell();
                cell.setNode(stack);
                //event listener for textbox
                box.setOnKeyPressed(new EventHandler<KeyEvent>(){
                    public void handle(KeyEvent event) {
                        if(event.getCode()==(KeyCode.ENTER)){
                            box.setVisible(false);
                            label.setText(box.getText());
                            box.setFocusTraversable(false);
                //property Change Listener of Focus in textbox
                box.focusedProperty().addListener(new ChangeListener<Boolean>(){
                    public void changed(ObservableValue<? extends Boolean> observable, Boolean oldValue, Boolean newValue) {
                        if(!newValue){
                            box.setVisible(false);
                            label.setText(box.getRawText());
                //finally trigerring the visibility of textbox on double click
                cell.setOnMouseClicked(new EventHandler<MouseEvent>(){
                    public void handle(MouseEvent event) {
                        if(event.getClickCount()==2)
                            box.setVisible(true);
                            box.requestFocus();
                return cell;
        });The above code runs the editing textbox when tablecell is double clicked.
You can manage the item of TableCell and make tablecell setNode() for more modification.
Please read the API for more information.

Making a Table cell editable. Please Help

Hello there,
I have written an Inner class called CallHeaderRenderer
which is used to select to highlight a row from a table.
But i am unable to edit the column data I click on.
Please can any one tell me how to edit the column value when you double click on it??
Attached is my Inner class used to select the concerned row.
I am unable to edit the concerned column.....
Please help.!!!
What is the statement to make the cell editable!!!
class CallHeaderRenderer extends DefaultTableCellRenderer{
public CallHeaderRenderer(){
super();
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column){
// Set the highlight for record chosen.
super.getTableCellRendererComponent(table,value,isSelected,hasFocus,row,column);
return this;
}

A renderer has nothing to do with editing the cell. I suggest you read this section from the Swing tutorial on "Using Tables" for an explanation of how tables work. The tutorial will give one method for making a cell editable:
http://java.sun.com/docs/books/tutorial/uiswing/components/table.html
Here is an alternate way to make a cell editable:
table = new JTable( ... )
    public boolean isCellEditable(int row, int column)
        // All columns, except the first, are editable
        if (column == 0)
            return false;
        else
            return true;
};

Table cells editing question...

I have a JTable and I can set the type of input (ComboBox, CheckBox, TextField) for a hole column. How can I set the type of input differently for each cell in a column (like the properties tab window in the design module in JBuilder, for example)?

You can implement TableCellEditor to return a different Component for a particular row, column, or value.

How to enable a table cell dynamically?

Hi
I have a javafx TableView with editable and non-editable columns. I have set editable columns CellFactory to a custom EditableTextCell.This makes the whole column editable on load of the Scene.
I have one more requirement for the same table. I have to make the table cell editable at runtime based on a flag in item mapped to tablerow. Only a single row cell should get editable not all the cells in column. How to do that? Please suggest.

Perhaps something like this
create or replace view v_myview
as
select id, name, 'table1' as tbl_nm from table1
union all
select id, name, 'table2' from table2
union all
select id, name, 'table3' from table3
union all
select id, name, 'table4' from table4
select name
from v_myview
where id = 101
and tbl_nm = :P101_TABLE_NAME;

Blinking Cursor in Table Cell

Can anybody tell me how I can blink the Cursor in the JTable. I am using JTable Cell as the user input field, I want to show a blinking cursor if user selects that cell.
Thanks in adv

Are your table cells editable? Are you talking about the Cursor in the TextField when your cell is edited? It is probably best to be as explicit as possible here.

I want to listen when value changes Use a TableModelListener
I also would like to activate the new cell value with ENTER keyThis is the default behaviour with the default editors. I suggest you extend the default editor instead of extending the abstract editor

How to stop editing in a table cell

i m using JTextArea as renderer and editor for table cell. While editing i want to stop editing in that cell at some perticular instance. i have used stopCellEditing() function on TableCellEditor but still the Caret does not goes away and when i press any key it still types that character at that place. I want to hide the Caret and do not want any character to print in the cell after calling stopCellEditing().

What you have already done, and the resulting behavior is unclear from your post. Post more details.

Theme Editor: where to change backgroundcolor of editable table cells?

Hi all,
I need to change the color of an editable table cell.
I navigated to the theme editor --> tables.There is a section "Editable Tables". The preview shows an example with three columns and tree rows. I want to change the backgroundcolor of the cell in the first row, third column (in SAP standard it is lightgrey).
The backgroundcolor of the rows beneath can be changed in section "Selected Cells", the backgroundcolor of the first two columns in the first row can be changed by "Background Color of Standard Table Cell" but I can't find the field where I can change the color of the last cell.
Best regards,
Sandra

Hi,
The blue color come from your definitions on "Labels and Fields" to read-only color of input field.

Table cells not editable in Contribute

I have a date table (inside a CSS layout) which displays incorrectly in Contribute Edit mode.This is the URL http://www.greencs.co.uk/accreditations.html
In Contribute Edit mode, the right hand column of the table (which contains the PDF certificates) is pushed far out to the right (beyond the rest of the layout) which makes it impossible for the cells in this column to be edited. This also happens in Dreamweaver; the table width is 598 pixels but the Display width (in parenthesis in Dreamweaver) is 1300 px. Does anyone know why the Display width, which I assume Contribute is using in Edit mode, is so wide..... and how I can constrain it.
I have tried adding various table cell widths but to no avail. Help.....
Many thanks

This problem has been solved by placing the logo images in their own table cell instead of floating left. The float and adjacent text caused the problem. Thanks to Neil Gibson @cvwcreative who came up with the solution on Twitter.

SOLVED: Editing a table cell won't update corresponding ViewObject

Hi,
I'm asking for your help.
I want to update a ViewObject with userinput from jTableCells. The JTable that has been constructed by JDev based on this ViewObject. The attributes of this ViewObject are the result of a SQL query using the NVL() function.
The Problem is that changing cell values does not update the ViewObject. I guess NVL() causes this. Right?
As a solution I'd like to add a TableModelListener to the table and take care that changes to cell-data find their way into the right ViewObject attribute. Is this the right solution?
How can I add a working TableModelListener?
My try:
jTable1.getModel().addTableModelListener(new MyTableModelListener());
The TableModelEvent, that MyTableModelListener gets, always returns "-1" for getColumn(). Why?
Is there another way to get the current row and column (where the cell-edit takes place)?
I hardly know anything about ADF, panelbindings and so on, so don't back off with answers that my appear too simple or obvious to you.
Regards, MaeSiuS

Hi Frank,
yes, it is based on EntityObjects.
For a test, I replaced one of the NVL() based attributes with the plain attribute of the EntityObject, but that had no effect on the update disability.

JavaFX2.2 TableView:How to make a table cell be edited without mouse click?

Hi,
I've encounter a problem with editable table cells. I'm using the TableView in my project just as the Tutorial on Oracle (http://docs.oracle.com/javafx/2/ui_controls/table-view.htm).
According to it, I use the setCellFactory method to reimplement the table cell as a text field with the help of the TextFieldTableCell class. However, I found the steps is a little complex to get to the point where the cell can be edited:
1.Let the table cell be selected by using direction key.
2.Press “Enter” to converts the cell to a text filed so that it is ready to be edited.
3.Clicking in the text field allows the contents to be edited
The problem is step 3, that you must use the mouse to click before you can input data in this table cell.
So, is there a solution to avoid step 3? That is the text field allows the data inputting when you just press “Enter”(step 2).
By the way, English is not my native language. Hope I have made myself clear.

Hi,
You need to pass the focus to the text field when the startEditing event occurs. In the class that extends TableCell you use for cellFactory:
public void startEdit() {
super.startEdit();
createTextField();
setText(null);
setGraphic(textField);
* put focus on the textfield so user can directly typed on it
Runnable r = new Runnable() {
@Override
public void run() {
getGraphic().requestFocus();
Platform.runLater(r);
}

Editable Dynamic Table Cells

Hi to all,
I am using studio creator and mysql.
I created a Dynamic table for Emp Names and Emp Skills, in that table for Emp Skills i put Text Feild.I am getting text feild in my table.
here is my doubt
I am trying to implement the functionality of editing table cells when clicked/doubleclicked on it. I am trying to make the cells editable(textboxes) only after clicking/double clicking them. It should display static text otherwise.
I am trying to do this one in Javascript onClick event.
Any sample code I can refer to.Any help is highly appreciated.
help me
jo

Hi friend,
Thanks for your kind reply.
what you have send is useful for static table, in static table we can bind any row.
But in my Module i am using Dynamic table, in that dynamic table for all the rows i need TextFeild.
when we open the page it has to show static text for all the cells and when we are clicking particular cell that Text feild has to open.
I dont no how to get Induival id for each and every cell, then only we can bind in dynamic table.
Any suggestions are welcome.

Select text of edited table cell

Hello,
I would like to have the text selected of a table cell i am editing. When i double click the cell, i can change the content of the cell, but i should manually select the text first.
I would like to have this text selected automatically.
Thank you in advance,
Rene Boere

Add a focus listener on the text field you are using in the cell editor. When the text field gets focus, tell it to select all of it's text. Something like this maybe:final JTextField tField = new JTextField();
tField.addFocusListener( new FocusListener() {
    public void focusGained( FocusEvent fe ) {
        tField.selectAll();
    public void focusLost( FocusEvent fe ) {
