Go to an Item in a JTable
Hey
When I press a button (for example NEXT) I want the JTable to go to that field . How can I do that cause I can't find it :D
You need to explain something more.

JTable moving items strangeness (desperate now)...
Hi there,
I've got a major problem that I just can't figure out. I've got two JTables, each with an instance of the
below datamodel. I've got two buttons. I want to highlight certain rows on the left JTable and use one of
the buttons to move across the selected items to the JTable on the right.
Two problems - the first is that the selected items are copied across fine, but instead of removing the
selected rows from the left JTable after copying to the right JTable, it leaves a random one. The other
problem is that if I highlight rows from near the bottom of the lefthand JTable, I get an
ArrayIndexOutOfBoundsException.
What the hell is going wrong here? I'm at a total loss.
This is my datamodel for both JTables...

if (e.getSource() == btnListAdd) {

for (int row = 0; row < selectedRows.length; row++) {
listItem = ((ListDataModel)tableUserList.getModel()).getRowAt(selectedRows[row]);
((ListDataModel)tableExcludeList.getModel()).addRow(listItem);
for (int row = 0; row < selectedRows.length; row++) {
((ListDataModel)tableUserList.getModel()).removeRowAt(selectedRows[row]);

I'm in desperate need of help with this. The errors just don't make logical sense to me. Little help folks?
Thanks.Here's your problem :
When you remove an element from your Vector, its size decreses.
Let's say you have 10 objects in your Vector :
the first time you remove an element, its size will become 9 (from 0 to 8)... and imagine that the second index of your int array is 9 !! you are out of bounds!!
what you should do is pass the entire indexes array to your data model, then create a new Vector (let's call it vect2) that you will feed with the objects pointed by your indexes.
then you remove the whole vector :
myData.removeAll(vect2); -
JComboBox rendering issue in JTable
I use a JComboBox to render certain items in my JTable.
When I use jdk1.3, the items render perfectly.
The problem is that when I use jdk1.4, the combobox is rendered with larger insets, clipping the bottom of the text.
Has anyone else had this problem?Okay - I can get the JComboBox and define an empty border for it. This means it renders okay.
What I don't like is stupid things like this creeping into jdk1.4 which weren't there in jdk1.3.
Thanks for the reply Rommie. -
JTable: Custom Table Model (pII)
As was explained in pI, I'm creating a custom table model to overcome a few pitfalls I came across using the DefaultTableModel class, such as aligning cells, and getting certain columns to return only numeric type data. However, I've come upon a few roadblocks myself.
How do I create each of the following methods:
insertRow(int ow, int column)
remove row(int row)
addRow(Object[] rowData)Assuming that I decide to allow the user to add a column to the table, how would I create the methodaddColumn(Object columnName, Object[] columnData)And also, as I'm creating a custom table model, would I need to replicate DefaultTableModel's methods that inform the listeners that a change has been made to the table?
Thanks!Thanks!
I just got this response. Anyways, I found another solution that was, interestingly, from one of your threads written in 2005.
This is what I did:
// Letting the JTable know what each column stores and should return by
// overloading the getColumnClass() method
public Class getColumnClass(int column)
if(recordsTable.getColumnName(column) == "Ranking")
return Integer.class;
/* Why do I keep ketting an IllegalArgumentException here? *
* It keeps saying it cannot format given object as a Number */
else if(recordsTable.getColumnName(column) == "Price (�) ")
return Float.class;
else
return getValueAt(0, column).getClass();
}However, another problem has arisen.
The if method for the int column (Ranking column) works okay, and is even right-aligned. The else if arguments for the Price (�) column however is returning an IllegalArgumentException. This I just cannot figure out.

How to keep the focus in a table cell as long as it is invalid?
Hello,
if you run the following code and enter some alphabetic characters in the Integer column,
you can't get out of the cell as long as focus transfer is within the table. But if you click in the textfield,
the cell is left invalid. (If you click in the textfield immediately after the false edit, the cell even doesn't
show the red border)
I tried to attach a focusListener to the table, but that makes editing the table impossible.
I also could attach a focusListener to each and every other component of the form,
and checking the table there in focusGained - but that looks rather awkward.
How would you proceed?

A big improvement is to apply
table.putClientProperty("terminateEditOnFocusLost", Boolean.TRUE);for this at least reverts the erroneous input to the last valid value.
Still I would prefer either to inform the user of this reversion or to red-border the erroneous cell;
for sometimes the [OK] button is at the bottom of a long form and putting one's eyes there for
clicking, one doesn't necessarily notice the reversion which happens at the top.Thanks to both of you!
@Jeanette
In my real application I use a JFormattedTextField as editor. Checking my overridden stopCellEditing() method I become aware that the contents of JFormattedTextField (getText() or super.getCellEditorValue()) arrives there already reverted. Thus it's no wonder that I cannot return false.
simply removes the editor on column resizingYikes! - Fortunately the table in question is not resizable.
SwingX has a NumberEditorExHow would you proceed if you didn't know that class and were looking for it? I still don't manage to navigate successfully on java.net.
@Walter
Never thought of this. Seeing that someone is checking for me (red border), I'd rather lazily let him continue doing the job. But a DocumentListener looks like being a way out. -
Intermediary bean causing NullPointerException
Hi all,
I wonder if someone could help me with an issue I'm having.
I've got a JTable bound to database fields, and when the user selects a field and clicks an "Edit" button, I'm generating an object using ConvertRowIndexToModel() method, and passing the Object to a JDialog form, using an intermediary bean object called currentPigment.
The currentPigment object is bound to various fields in the JDialog, and the bound properties are showing up correctly in the JTextField boxes. If I try to access the bean properties from the JFrame class where my JTable exists, everything is fine. However If I try to access the intermediary bean from within the JDialog, I'm getting a NullPointerException.
Here is the code from the JFrame holding the JTable linked to the database:
@Action(enabledProperty = "recordSelected")
public void editPigment()
PigmentEditor pe = new PigmentEditor(this, false);
pe.setCurrentPigment(pigmentList.get(pigmentTable.convertRowIndexToModel(pigmentTable.getSelectedRow())));
pe.setVisible(true);and here is the bean code in the JDialog class:
protected Pigment currentPigment;
public Pigment getCurrentPigment()
return currentPigment;
public void setCurrentPigment(Pigment currentPigment)
Pigment oldCurrentPigment = this.currentPigment;
this.currentPigment = currentPigment;
propertyChangeSupport.firePropertyChange("currentPigment", oldCurrentPigment, currentPigment);
}I need to access the properties of the currentPigment object so I can automatically select an item from a JTable, however if I try to access the objects getters/setters, I get a NullPointerException.
If someone could explain why this is, or how I can get round it, I'd be greatful.
Thanks in Advance.Okay I figured out what the problem was / is - When the JTable is bound to the nested entity class, because no item is selected, it's removing the nested entity class creating a null value. I also tried changing to a JList and this does the same thing. However if I use a JComboBox, my item renders correctly and the nested entity class displays the correct value without being erased.
Is it possible to make a JTable select an item, before the bean binding removes the value making it null?
Many thanks, -

JInternalFrame, auto activate when mouse enters the frame
Hi, is there a simple way to make the JInternalFrames automatically get activated as soon as the mouse enters them?
I would like this in general, but specifically I need it for a drag'n drop operation. I want to drag an item from a JTable in one frame to another JTable in another frame. This works perfectly, even if the recepient frame is not active, what doesn't work is to scroll the recepient JTable using the mouse scrollwheel before dropping the item. This would work if the frame was active. (I tested this by temporarily placing the two JTables in the same internal frame)Thanks, this looks promising, unfortunately I read the stuff about glass panes but I can't seem to make it work anyway. As I understand it the default glass panes should block all events. This does not happen, even when I turn the glass panes visible on all JInternalFrames and the main JFrame. Everything is just like it was before... With this I mean that mouse events were sent to the mouse listener I added to the glass pane, but the mouse events also went to the underlying JInternalFrames. And when a drag'n drop was active, no mouse events are reported. What glass pane should I make visible for it to intercept all events?

Different JCombobox items in JTable for the same column
Hello Everyone,
I am reading from a file and displaying in a JTable. I want all cells in a specific column to be JComboBoxes but the items in the JComboBox differ from one cell to another, how can this be achieved?
The following is a snippet from the Sun tutorials,
JComboBox comboBox = new JComboBox();
comboBox.addItem("Snowboarding");
comboBox.addItem("Rowing");
comboBox.addItem("Knitting");
comboBox.addItem("Speed reading");
comboBox.addItem("Pool");
comboBox.addItem("None of the above");
sportColumn.setCellEditor(new DefaultCellEditor(comboBox));
And hence every cell in the sportColumn has the exact same set of options in the JComboBox which is not what I want since I read from an external file.
Any help or sample code would be highly appreciated.
Thank you in advanceOverride getCellEditor(int row, int column) in JTable to control which editor gets used for which cell.

Peter 01-jan-43 62
Ron 03-nov-73 32
when double clicking the name( eg peter), a new window pops up contains all relevent info of the user.
I added a sorter and when sorting the table it comes in the correct-wanted order, however, when double clicking the item - the wrong window pops up.
I take it the DefaultListModel is not synchronized with the tables elements.
Q: how to correct the DefaultListModel once the table has been sorted so it will be in sync with the jtable.
thanks
peterthank you camicker for replying.
I have been trying for the past 4 hours to dig in the code (as well as google) to find where to implement a sync with the DefaultListModel. Nothing.
any input?

Setting color of an item in a Jcombobox in a JTable when editing
Hello,
I have a situation where I have a JCombobox in a JTable . The JCombobox is non-editable. The items within the combobox are colored in pink or blue in order to help the user differentiate between the two categories that are in the list.
But the problem is that when the user is on that cell and is just typing the first letter(s) in the combobox, he does see the item starting with that letter(s) but that item is not shown as colored. However, if the user clicks on the combobox with a mouse, the list pops-up and the items are shown as colored. I want the first part to work where the user can just use keyboard and see the items as colored in that cell itself. By default, currently when the row is selected the foreground is white and background is black. I want that particularly when this combobox has focus and an item is selected, the foreground should be of the same color as the color of the item.
Can someone help?
Thanks a lot in advance.Additional information on above:
I associate a customized renderer with the column of my table for which i want to set the colors.
TableColumn tc6 = jTableDRS.getColumnModel().getColumn(myDRSModel.FINANCECODE_COLUMN);
tc6.setCellRenderer(new ColorRenderer());
here is the renderer that I am using...
public class ColorRenderer extends JLabel implements TableCellRenderer {
protected Border noFocusBorder;
public ColorRenderer() {
noFocusBorder = new EmptyBorder(1, 2, 1, 2);
setOpaque(true);
setBorder(noFocusBorder);
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus, int row, int column) {
Color foreground = null;
Color background = null;
Font font = null;
if(column == myDRSModel.FINANCECODE_COLUMN)
setFont((font != null) ? font : table.getFont());
String str = (String)value.toString();
if (!str.equalsIgnoreCase("SELECT ONE")) {
int y = financedesc.indexOf(str);
if((payreceiveind.get(y).toString()).equals("R")){
setForeground(Color.RED);
} else if((payreceiveind.get(y).toString()).equals("P")){
setForeground(new Color(147,112,240));

setForeground(Color.RED);
} else if((payreceiveind.get(y).toString()).equals("P")){

Update JTable when an item is selected in a JComboBox inside the same JTabl
I created a JTable with a lookup JComboBox. I want to update values from the table when an item is selected in the ComboBox.
I tried all the events posible in JComboBox, but I can not fire to update the JTable.
Please if you have a how-to, (source) will help. Thanks.
Regards,
-RoryI tried that. But it only fires when the JComboxBox, lost the focus. And not in the "itemChange" event. How to do it width that event?
I want something like "intemChange" event, to fire the JTable.fireTableChangeUpdate(); ... I send the code.

How do you set new items within a JComboBox that is within a JTable
I have searched and searched for the answer to this and do not thing there is one. I have a JTable that has 5 columns. 2 of the columns use DefaultCellRenderers where a JComboBox is used. One of the columns has a value of different football positions. The other has a value of the different players. When a user enters a particular position such as Kickers I want all the Kickers to be showin within the Players JComboBox within the table.
The problem is that I ONLY want the cell to be modified within that row and column that the position was changed. I have found ways to modify the component but it modifies it for the whole Column. I only want it to be modified for the player cell within the row that the Position was modified. Bottom line is that I just want to modify the JComboBox's components.
If anyone has had this challenge before please advise.I'm not sure I fully understood what you wanted. Does the following little program help you?import javax.swing.*;

There is another solution. You also can override the table's prepareEditor method and add the relevant code before returning the Component.
