JTable with JComboBox/JSpinner problem

The following code has a JTable with 2 columns.The lst column has JComboBoxes, the 2nd column has JSpinners.I want to set the spinner range of values based on the selection of JComboBox. The JComboBox selections are "small" and "large". For "small" the spinner should range from 0..49, for "large" from 50..99. When a selection is made, MyTable.itemStateChanged() is called, which in turn calls SpinnerEditor.setValueRange(). This sets an array with the desired values and then sets the model with this array. However, it sets the range not only for the row in which the combo box was clicked, but all rows.
So in MyTable.setCellComponents(), there is this:
spinnerEditor = new SpinnerEditor(this, defaultTableModel);
modelColumn.setCellEditor(spinnerEditor);
If the table has n rows, are n SpinnerEditors created, or just 1?
If 1, do n need to be created and if so, how?

          spinner.setModel(new SpinnerListModel(java.util.Arrays.asList(spinValues)));

However, it sets the range not only for the row in which the combo box was clicked, but all rows. Yes, because a single editor is used by the column.
One solution is to create two editors, then you override the getCellEditor(...) method to return the appropriated editor. Something like:
If (column == ?)
    if (smallOrLarge)
      return the small or large spinner editor
    else
       return the large spinner editor
else
    return super.getCellEditor(...);

JTable with JComboBox cells

Hi all,
When I make the JComboBox(es) become the cell of the JTable, the list of JComboBox is not expanded as the way a JComboBox behaves when you click on the arrow to see the whole list. I think the JComboBox is not receiving the mouse click event. Another way to say, something keeps the JComboBox from receiving the mouse click.
Has anybody experienced this scenario?
Frank.

Is the table cell editable? If it isn't, that is your problem. Enable cell editing for that cell(s).

JTable CellEditor JComboBox Tab Key

Hi,
I use JDK 1.4.1_01 and got a JComboBox as CellEditor inside a JTable.
Now I tried:
table.setSurrendersFocusOnKeystroke(true);
So the table gives up focus to the editor e.g. after the TAB Key is pressed while navigating through the table.
But there is another Keyboard Event necessary to activate the JComboBox in the Editor (the arrow on the right becomes visible).
Is there a possibility to make the JComboBox visible right after TAB was pressed?
Thanks in advance!

just a guess, didnt try it but... try to set
public boolean shouldSelectCell(EventObject anEvent)
return false;
}in your cell editor
hope it helps

Creating a dynamic JTable wit JComboBox

I am trying to create a dynamic Jtable such that the first column is editable and the other columns contain JComboBoxes that contain as items all the elements of the first column. I can build the table, but I want to make it dynamic so that when the contents of a cell in the first column are changed, all the combo boxes are updated to reflect this change. In general, what is the best way to do this?

How to stop Auto Edit in JTable With JComboBox or JTextField

Hi everybody
I'm working with JTable and having 5 columns last 3 are hidden. First contains a Combobox Editor and Second contens JTextbox for editing. Every thing working fine except that whenever i clik the table it automatically opens its editor either JComboBox or JTextField for editing.
I want to remove this and want to allow editing whenever user press Enter key on that column.
I am using class
FeeAmtEditor extends JTextField implements TableCellEditor for Textbox editing and class FeeTypeEditor extends JComboBox implements TableCellEditor for combobox edition
another promblem that I need to press 'Escape' key to deactivate combo box or text box after entering data. This also i want to avoid.
thanks in advance

JTable inside JComboBox

Hi all,
I was looking at the example
http://forum.java.sun.com/thread.jspa?forumID=57&threadID=413291
Please any one help me ... how I can make comboBox multicolumn ... ???
regards,

You need to either write your own implementation of Table Model; or use something like javax.swinf.table.DefaultTableModel. In particular, look at how getRowCount and getColumnCount are implemented.
When you've decided on your model, just call JTable.setModel.

Problem with JTable and JComboBoxes in cells

Hello,
I've build a Table with static comboboxes in the first row. These comboboxes are static because they are used to filter the content of the table.
I extended AbstractTableModel for the data handling and I use the DefaultCellRenderer for combobox handling.
So far everything works fine. But if I gain focus to one combobox and then click to another cell (either table cell or another combobox) i receive a NullPointerException from within the component:
java.lang.NullPointerException
     at javax.swing.plaf.basic.BasicTableUI$MouseInputHandler.adjustFocusAndSelection(Unknown Source)

Actually I could leave the table as it is now because there are no obvious errors but I don't think its a good job to ignore exceptions.
Does anyone see where this problem could come from????
Do I have to extend the BasicTableUI somehow because the exception is thrown in there???
Thanks for any help!
Bye Jan

Hi brad,
I'm using eclipse and java1.4.2_06. Isn't it enough to write the program arguments to the run configuration in eclipse?!
I tried that but it didn't work out, I get the same error msg. :(
But I can say that whatever happens inside the UI, the exception is thrown before I receive a mouseClicked event on the table itself. I added some kind of dummy mouse listener to the table that only prints the events to the console. Is the cell renderer or cell editor using is own MouseAdapter?
You said: ...consume the event so the table won't react....
How could I catch this MouseInputHandler???
Thanx!

Exception raised using JComboBox with JUComboBoxBinding in a JTable

Hello,
I am using JDeveloper 9.0.3.1035.
I have a JTable bound to a bc4j view object. Now I want to use a JComboBox to select the value for a foreign key column in that Table. For this I have followed the HOWTO posted by Arno van der Kolk in Thread JClient - JTable and JComboBox which extends the OTN example "How to Add a JComboBox to a Cell in a JTable". This almost works fine except for one thing:
In the the ComboBox I display a String value but the view attribute is of type Number. Now when I edit the column using the ComboBox and the value of the selected entry cannot be converted to Number I get an exception like the following:
oracle.jbo.domain.DataCreationException: JBO-25009: Cannot create an object of type:oracle.jbo.domain.Number with value:030522 001
Even after this exception is raised the database record is updated with the correct number value corresponding to the selected entry when the changes are commited. The only w/a I have found so far is to display the foreign key attribute as the first column of the JComboBox but this is not what I want. This behaviour also occurs using the aforementioned OTN example with my JDev version but the sample works with JDev 9.0.2.
How can I get this to work using JDev 9.0.3?
Any help is greatly appreciated.
Regards,
Christof Breker

The Thread I was really referring to is:
[JClient] HOWTO: Using databound comboboxes (for foreign keys) in a JTable
The OTN sample can be found under:

Event handling of JComboBox outside a JTable

Hi to All,
I've a question about JTables and JComboBoxes... I'm working on a application which holds a JTable and several JButtons and JCombBoxes. When the user clicks on a cell in the JTable, this cell will get the focus and the text will be highlighted. An action will be performed when the user clicks on a JButton (this just works fine). When the user clicks on a JComboBox also an action must be performed... but this won't work. I guess it won't work because of the JComboBox will draw a popup, and this popup will be cover the cell with the focus...
I could not catch any event of the JComboBox...
How can I check for a click on a JComboBox when an other component (JTable cell) has the focus?
Thnx,

Hi Swetha,
Button controls in a table are available only in version 2.0 of the .NET PDK.
In order to use Button in a table and handle its events u will have to upgrade.
Further information about using input controls in a table is available in the How to section of the PDK documentation.
Thanks, Reshef

Refresh data in JTable

hi, i hava a problem, i have a jtable where same Data column depend from another column of the same jtable and a jtextfield that is external to jtable
my jtable is
jcombobox | text | text | text ecc....
when the user change the SelectedItem of jcombobox the other column`s data is jacombobox values * external JtextField text....
if i change the value of the external jtextfield how can i refresh the data in the jtable whitout click over all cell???
this is the code of the My CellRender of the first column:
public class MyComboBoxRenderer extends JComboBox implements TableCellRenderer {
    JTable jt;
    PortataUgelli pug;
    public MyComboBoxRenderer(String[] items,JTable table,PortataUgelli pu) {
        super(items);
        this.jt=table;
        this.pug=pu;
        addItemListener(new java.awt.event.ItemListener() {
            public void itemStateChanged(java.awt.event.ItemEvent evt){
                if (jt.getSelectedColumn()==0){ //This action is only for the first column
                    String ugello= (String)getSelectedItem();
                    if (ugello==null) ugello=""+0;
                    double b=Double.parseDouble(pug.getPressione().trim());
                    String par="" + new VariID().getFunzioneUgelli(ugello,b); //this method calculate the value of the other cell
                    int sel;
                    if (jt.getSelectedRow() < 0) sel=0;
                    else sel = jt.getSelectedRow();
                    jt.setValueAt(par,sel,1); //set the value of the cell
    public Component getTableCellRendererComponent(JTable table, Object value,
            boolean isSelected, boolean hasFocus, int row, int column) {
        if (isSelected) {
            setForeground(table.getSelectionForeground());
            super.setBackground(table.getSelectionBackground());
        } else {
            setForeground(table.getForeground());
            setBackground(table.getBackground());
        // Select the current value
        setSelectedItem(value);
        return this;
}

It's fairly simple...
you need to have your own custom TableModel. Extend AbstractTableModel and when you go to set a cell (to change the data in that cell) you simply fire an event with the:
fireTableCellUpdated(int row, int column) method to let the view know that the data changed in that cell of that table changed and needs to be redrawn...
Here's the link to the tutorial page/section on creating a custom table model and also firing events when data changes:
http://java.sun.com/docs/books/tutorial/uiswing/components/table.html#data

How to enable JScrollPane in a cell of the JTable

Hi,
I am able to place the components into the cell of the JTable. But I am unable to interact with the components like JTable or JComboBox after inseting them into a cell of the JTable.
This was the one of the Scenario:
Step 1: I created One JTable named as "insertTable"and adding to JScrollPane
Step 2: I'm able to inserted the newly created JTable ("insertTable") in to a cell of another JTable(like table inserting a table) using TableCellRenderer.
here was the problem. I am able to insert the newly created table into the cell. the "insertTable" size is greater the Cell size. So, the "insertTable" is appering with Horizantal and Vertical Scrollbars because the "insertTable" is added to JScrollBar. but I am unable to move the scrollbars.
please any one help me for this.

you still didn't try to learn the difference between cellEditor vs cellRenderer - as you were advised to do more than once in recent posts.
If you do, the answer will be obvious (to you :-). As long as you don't there's nothing to help
Cheers

Tom
Another guess is that you are getting selection events from the combo box as the JTable initialises it for editing the cell valueLooks like just the opposite to me -- when the cell is selected for editing, the previously selected item in its (combobox) editor remains selected, which does not trigger a itemStateChanged event in 1.6.x as in some earlier version (not sure exactly when the behavior changed). That's why
when i swith from one combox box to another combo box the details of the previous sombo box is displayed.The solution might be for getTableCellEditorComponent to call the same code as called by itemStateChanged which should, of course, be in a method of its own.
But you're right, we're playing guessing games here.
@OP: I strongly suggest that you post a SSCCE, a short program that demonstrates your problem.
