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).

Problem sorting JTable with custom cell editor

Greetings,
I have created a JTable with a JComboBox as the cell editor for the first column. However, I couldn't simply set the default cell editor for the column to be a JComboBox, since the values within the list were different for each row. So instead, I implemented a custom cell editor that is basically just a hashtable of cell editors that allows you to have a different editor for each row in the table (based on the ideas in the EachRowEditor I've seen in some FAQs - see the code below). I also used a custom table model that is essentially like the JDBCAdapter in the Java examples that populates the table with a query to a database.
The problem comes when I try to sort the table using the TableSorter and TableMap classes recommended in the Java Tutorials on JTables. All of the static (uneditable) columns in the JTable sort fine, but the custom cell editor column doesn't sort at all. I think that the problem is that the hashtable storing the cell editors never gets re-ordered, but I can't see a simple way to do that (how to know the old row index verses the new row index after a sort). I think that I could implement this manually, if I knew the old/new indexes...
Here's the code I use to create the JTable:
// Create the Table Model
modelCRM = new ContactTableModel();
// Create the Table Sorter
sorterCRM = new TableSorter(modelCRM);
// Create the table
tblCRM = new JTable(sorterCRM);
// Add the event listener for the sorter
sorterCRM.addMouseListenerToHeaderInTable(tblCRM);
Then, I populate the column for the custom cell editor like this:
// Add the combo box for editing company
TableColumn matchColumn = getTable().getColumn("Match");
RowCellEditor rowEditor = new RowCellEditor();
// loop through and build the combobox for each row
for (int i = 0; i < getTable().getRowCount(); i++) {
JComboBox cb = new JComboBox();
cb.addItem("New");
//... code to populate the combo box (removed for clarity)
rowEditor.add(i,new DefaultCellEditor(cb, i))); //TF
} // end for
matchColumn.setCellEditor(rowEditor);
Any ideas how to do this, or is there a better way to either sort the JTable or use a combobox with different values for each row? Please let me know if more code would help make this clearer...
Thanks,
Ted

Well, I found a solution in another post
(see http://forum.java.sun.com/thread.jsp?forum=57&thread=175984&message=953833#955064 for more details).
Basically, I use the table sorter to translate the row index for the hashtable of my custom cell editors. I did this by adding this method to the sorter:
// This method is used to get the correct row for the custom cell
// editor (after the table has been sorted)
public int translateRow(int sortedRowIndex)
checkModel();
return indexes[sortedRowIndex];
} // end translateRow()
Then, when I create the custom cell editor, I pass in a reference to the sorter so that when the getTableCellEditorComponent() method is called I can translate the row to the newly sorted row before returning the editor from the hashtable.

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?

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(...);

How can we have a JTable with rounded cells

I want to create a JTable with circular or oval shaped Cells, can anybody please help me as to how to go about it?
Thanks in advance

If you share an Apple ID for purchases then you share all purchases.
You can hide purchases that are not synced locally (with the cloud icon next to them) to the device here:
Settings > Music > tuen Show All Music off
I suggest you create a playlist for each person in iTunes on your computer with only their music on it. Then sync just that playlist to each persons device.

JTable tab key navigation with JComboBox Cell Editors in Java 1.3 & 1.4

Hello - this is one for the experts!
I have a JTable which has an editable JComboBox as one of the cell editors for a particular column. Users must be able to navigate through the table using the tab key. After editing a cell a single tab should advance the cell selection to the next column and then the user should just be able to start typing to populate the cell.
However, i've come across some really frustrating differences between the Swing implementation of JDK1.3.1_09 and JDK 1.4.2_04 which means this behaviour is very different between versions!....
1. Editing Cells and then advancing to the next column using tab.
Using standard cell editors (based around JTextFields) in 1.3.1 the user has to press tab twice to traverse to the next column after editing. However, in 1.4.2 a single tab key is enough to move to the next column after editing.
2. Editable JComboBox editors and and advancing to the next column using tab.
Using JDK 1.3.1, having entered some text in the editable combo it takes 2 tabs to transfer the selected cell to the next column. With 1.4.2 a single tab while editing the editable combo ends editing and transfers the selection out of the table completely?!?
With these 2 issues I don't know how to make a single tab key reliably transfer to the next cell, between java versions. Can anyone please help me?!??!
(i've attached test code below which can be run in both 1.3 and 1.4 and demonstrates the above behaviour.)
package com.test;
import java.awt.*;
import javax.swing.table.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
public class TableTest4 extends JFrame {
     private JTable table;
     private DefaultTableModel tableModel;
     public TableTest4() {
          initFrame();
      * Initialises the test frame.
     public void initFrame() {
          // initialise table
          table = new JTable(10, 5);
          tableModel = (DefaultTableModel) table.getModel();
          table.setPreferredScrollableViewportSize(table.getPreferredSize());
          table.setRowHeight(22);
          JScrollPane scrollPane = new JScrollPane(table);
          getContentPane().add(scrollPane);
          JButton dummyBtn1 = new JButton("Dummy Button 1");
          JButton dummyBtn2 = new JButton("Dummy Button 2");
          // initialise frame
          JPanel btnPanel = new JPanel(new GridLayout(2, 1));
          btnPanel.add(dummyBtn1);
          btnPanel.add(dummyBtn2);
          getContentPane().add(btnPanel, BorderLayout.SOUTH);
          // set renderer of first table column to be an editable combobox
          JComboBox editableCombo = new JComboBox();
          editableCombo.setEditable(true);
          TableColumn firstColumn = table.getColumnModel().getColumn(0);
          firstColumn.setCellEditor(new DefaultCellEditor(editableCombo));
     public static void main(String[] args) {
          TableTest4 frame = new TableTest4();
          frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
          frame.pack();
          frame.setVisible(true);

Run the above code in 1.3 and 1.4 and you can see that after editing a cell, the tab key behaviour works differently between versions.
I don't believe by adding a key listener to the cell editors will have the desired effect.
I've read other posts and from what i've read it looks like the processKeyBinding method of the JTable can be overridden to manually handle key events.
Has anyone done this to handle tab key presses so that the same java app running under 1.3 and 1.4 works in the same way ??? I would really appreciate some advice on this as its very frustrating !

Size of combobox in JTable with custom cell editor

Hi All -
I have a JTable that displays a combobox in certain cells. I have a custom table model, renderer, and editor. All of that works fine. I render the combobox with the renderer, and then return the combobox as an editor in the editor so that it can drop down and actually be of use. My problem is - I set the size of the combobox with a setBounds call in the renderer, I add it to a panel, and return the panel - because I dont want the combobox to take up the entire space of the cell. This approach fails in the editor. The setBounds and setSize calls have no effect. As soon as you click the combobox, the editor takes over and all of a sudden the combobox resizes to the entire area of the cell. I assume this is because in the editor you arent actually placing anything - your simply returning the "editing form" of the component.
So - anybody know of a way to work around this? Worst case, I could just allow the combobox to use the entire area of the cell - but it makes it uglier so I figured I would run it by the forums.
Eric

Rather than just redirect you to my previous answer from ages ago, I'll just give it again. :-)
You can actually do this, but you have to get tricky. By default, the dropdown's width will be the same width as the cell... but it doesn't have to be that way. Essentially what you have to do is override the UI (MetalComboBoxUI) for the combo component. In your new customized UI component subclass (that you set the combo to use), modify the the createPopup() method of this UI class, and add your own logic to set the size of the popup before you return it.
Ideally the size would be based on the computed max width of a rendered item shown in the combo, but really you could set it to whatever just to see how it works.

JTable with JButton Cell renderer

How can I get buttons (JButtons) to "depress" properly in a JTable when using them as the cell renderer for a specific column in a JTable? Currently when pressing any button in the column, there is no change in the visible state of the button, i.e. it doesn't change color to create impression of depression.

Is the [problem not the fact that the JTable cell renderers merely rubberstamp each cell with the appropriate display, i.e. the actual component in the cell is not an actual button (just looks like one)? If this is the case, then the same problem will persis with a JToggleButton as well won't it?

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

public void setComboBox(JComboBox cb, int columnindex)
        if(columnindex < 0 || columnindex >= getColumnCount())

        dce.setClickCountToStart(2);
        TableColumn column = jtable.getColumn(getColumnName(columnindex));
        column.setCellEditor(dce);
    }hope this help you..

JTable with custom cell for folding and unfolding rows

Hi,
I am trying to implement a JTable, whereas one of the columns is a custom component, which has a small + in the right upper corner.
When you push this + the JTable should unfold other rows, giving more detail on the current row.
So something like this :
|--------------------------------|
| <some-string> + |
|--------------------------------|Drawing this custom component for the column is no problem but I am having trouble implementing the MouseMotionListener events over this.
If I add a mouseMotionListener to the JTable, I am able to forward these events to my custom class which draws this custom component.
But off course the X and Y coordinates of this MouseEvent are not mapped into the grid of my custom component, which poses my question.
How can I attach to each cell of this custom column of my JTable, a listener as to implement some mouseover and mouseclick stuff ?
In case this post is not all that clear, I will try to add a demo showing my problem.
Kind regards,
Wim.

You're reinventing a wheel that's been done a few times. One example is JTreeTable (http://community.java.net/javadesktop/) but there are others.

JTable with Labeles cells

Is it possible to create Table where each cell
will have permanent label (its number) together with an editable text?

Yes we can have it like that
for that u need to create a panel with one label and textbox in it
and renderer that column with this panel

JTable with more cell editors??

Hi,
I have a JTbale in which I have two special columns- one with buttons and the other similar to the the color changer from the swing tutorial.
My question is should I have now two renders and two editors in this situation?

Need help serializing an AbstractTableModel for a JTable with cell editing.

Fun times are ahead. Here we go!
I have a JTable that contains data I'd like to serialize out to a file to be restored and viewed later.
So I tried saving the AbstractTableModel subclass out to a file. Whenever I do this, I get the following error message:
java.io.NotSerializableException: javax.swing.JTable$CellEditorRemover
Now I know for fact that serializing an AbstractTableModel that was installed in a JTable without cell editing works just fine (my old code did exactly that). As a result, I think that the code that handles events in the AbstractTableModel contains references back out to the JTable, which causes the JTable to be saved no matter what (even though I'm just interested in saving the TableModel only). It causes a bigger file than normal, but file size is not an issue. The only issue I have is that CellEditorRemover (an undocumented inner class of JTable), which is automatically installed for JTables with editable cells, is not serializable.
This leads to the following questions:
1. Is there a way to avoid serialization/deserialization of the CellEditorRemover inner class of JTable?
2. Is there a way to save an AbstractTableModel without saving all of the event listeners associated with it?
I think an answer to either of these questions would go a long way towards solving my problem. Otherwise, I'll resign myself to weeping silently in the corner of my office.
Thanks!

I would suggest that if you can you only save the
data... but i would do this by using the
externalizable interface.
What you will need to do is have the
writeExternal(ObjectOutputStream out) and
readExternal(ObjectOutputStream out) methods in your
class. These will be responsiable for saving the
data.
Here's an example of what you can do in these
methods... this is just a little tidbit from a program
i've written.public void writeExternal(ObjectOutput out) throws
IOException {
          out.writeInt(size);
          out.writeObject(drawName);
          out.writeInt(playersLength);
for(int i = 0; i < playersLength; i++)
) out.writeObject(players);
          out.writeInt(seedsLength);
for(int i = 0; i < seedsLength; i++)
) out.writeObject(seeds[i]);
          out.writeInt(drawLength);
for(int i = 0; i < drawLength; i++)
) out.writeObject(draw[i]);
public void readExternal(ObjectInput in) throws
IOException, ClassNotFoundException {
          size = in.readInt();
          drawName = (String)in.readObject();
          playersLength = in.readInt();
for(int i = 0; i < playersLength; i++) players[i] =
= (String)in.readObject();
          seedsLength = in.readInt();
for(int i = 0; i < seedsLength; i++) seeds[i] =
= (String)in.readObject();
          drawLength = in.readInt();
for(int i = 0; i < drawLength; i++) draw[i] =
= (String)in.readObject();
You can now use your class as you would a Serializable
class, but it will only save the data
Hope this helped
webaf409java
I forgot to add some critical information in my original post. My apologies. :(
I've thought about using Externalizable, but am hesitant to use it because the application would no longer be able to read in files using the old save format (ie, AbstractTableModels for JTables without CellEditorRemovers ). I want to preserve the ability to read the old saved AbstractTableModel formats if possible.
Do you know of a way to revert to the default deserialization mechanism from readExternal? This way, during deserialization, I could do a quick test on the object being read and have the ability to default to the regular deserialization mechanism if the object is of the old type or continue with the new Externalizable stuff if the object is one of the new type. Maintaining file compatibility is key.

Row with one cell in JTable

I have a JTable with multiple cells per row. However, in-between some rows, I would like to have a header row which doesn't change as I scroll horizontally. Is that possible?
Another question about JTables: Is it possible to have fixed cells on the right as well as on the left, with some cells in-between which you can scroll?
