JTable row filtering

Hi -
Does anyone have any samples / pointers on implementing custom exclusion filtering of rows in a JTable? I understand that I would use a 'middle' model layer similar to a sortable model, but am having difficulty getting my arms around how to write the model to allow the filtering to be customizable? (i.e. the user could decide to see all rows of a Person table, whose last names are between A and D, but then could turn around and perform another filter to see only rows of Person's between the ages of 10-25.).
Thanks,
Kelly

I've never used them for filtering, but I think the couple TableMap/TableSorter can help you.
I've used for sorting purpose, and they work properly.
You'll find them somewhere in the jdk's doc or guide

Grouping and UnGrouping of JTable Rows?

Hi,
Has somebody done Grouping and UnGrouping of JTable Rows as we find in MS-Excel.
Thanks & regards
blue

Hi,
Have anyone done something like this.
If u r not clear about the requirement:
Please see the screenshot uploaded at below url:
[http://www.geocities.com/coolneela/GroupableTable.JPG]
As shown the screenshot i want the Group 1 ,2,3 to be expandable and hideable i.e should behave like a Jtree node.....In rest of the column User can enter any input i.e for the columns A,B,C..
thanks & regards

Sort jTable rows by column as Integer value

Hi all,
I have problem with sort jTable rows. I have some columns and in first are integer data. jTable sort that as String value..1,10,11,12....2,21, ...
How can I do that?
Thanks

In the future, please post Swing questions to the Swing forum: http://forum.java.sun.com/forum.jspa?forumID=57
What does the TableModel's getColumnClass method return for that column?

Can a single char be used both in rows, filters and free chars

Hi.,
Can 0customer can be used in rows, filters and free chars at a time ?
Or the chars which are used in either one of themrows or filters or free chars) cant beused in the other(rows or filters or free chars)?

NOpe, it can only be used in one place.
May be what you have seen is it could be a nav. attribute of master data and transactional data with the same name. Or the same object name could have been in two different underlying model of infoset and it would be dragged and dropped with the same name.
thanks.

hi again camickr
i changed the stopCellEditing as you mentioned
changed the getCellEditorValue to return an integer
and give exception and error message if the value can't be converted into integer(non numeric)
but the problem is when i run the program and change the value in any cell with numeric values
or with non numeric or not changing the value and press enter
it give the error message meaning it cannot convert the value to integer
even if enter an int or don't change the value ????????
here's what i did

How to get String form java JTable row?

Changing JTable Row Color OnMouseOver

Hello everybody,
is it possible to change JTable Row Color when Mouse passes over it ??
THanks!

Yes...
You have to override the table cell renderer and set the color of the rows based on flag.
The flag can be turned on/off in a mouse motion listener of the table.

Making JTable rows not editable

i need to make a jtables rows and columns to not be editable, but i also need it to be able to be selectable. i know one way to do it is to extend defaulttablemodel and overwrite the iscelleditable method, but the problem is that i'm already extending jframe. is there any other way to do this keeping jframe extended, because i need it to be extended?
thanks for the help

Double click on a JTable row.

I got and run a sample about double click on a JTable and it works fine. This sample defines a TableModel as shown at the end this note.
On the other hand, I have an application in which I have defined a JTable
using the DefaultTableModel as follows :
DefaultTableModel dtm = new DefaultTableModel(data, names);
JTable table = new JTable(dtm); where data and names are String arrays.
Of course the mouse listener stuffs have been also specified.
table.addMouseListener(new MouseAdapter(){
     public void mouseClicked(MouseEvent e){
      if (e.getClickCount() == 2){
         System.out.println(" double click" );
     } );Because the difference with the sample was the table model,
I changed it with the DefaultTableModel class. At this point, the Double click does not work anymore.
So I gues it should be an option which prevents double click to work.
I thought of using mousePress() instead of mouseClick(), but it's very dangerous (I tried). . If by error the user clicks twice (instead of only once) the mousePress method is invoked twice for the same entry
My question is now simple, may I use double click on a JTable with the default table model. If so, what I have to do ?
Thanks a lot

Making a jtable row noneditable based on a value in a certain cell.

I have a jTable (based on a database table) and one of the columns is OWNER. Is there a way to make an entire row noneditable based on the value in the OWNER column of the currently selected row?
Here is the listener code that I have on the jTable. I want to be able to make the entire row noneditable if the value (of the currently selected row) of the OWNER column is "SYSTEM". If it is anything other than "SYSTEM" then the user would be able to change the values on the row.
I can't override the isCellEditable method, because I only want the rows with the value of "SYSTEM" in the OWNER column to be noneditable.
jTable2.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
ListSelectionModel rowSM = jTable2.getSelectionModel();
rowSM.addListSelectionListener(new ListSelectionListener() {
public void valueChanged(ListSelectionEvent e) {
if (e.getValueIsAdjusting()) return;
ListSelectionModel lsm = (ListSelectionModel)e.getSource();
if (lsm.isSelectionEmpty()) {
//no rows are selected
} else {
int selectedRow = lsm.getMinSelectionIndex();
if (jTable2.getValueAt(selectedRow, 1).equals("SYSTEM"))
System.out.println("Selected Row: " + selectedRow);
System.out.println("Owner Value: " + jTable2.getValueAt(selectedRow, 1));
//Make all cells in this row non-updateable???
//Need code to make the currently selected row noneditable
disableRetailerAddToList();
} else
enableRetailerAddToList();
Any direction for this problem would be greatly appreciated.

I've resolved it with some help by using the following:
NOT ([<plCall_Back_Required_ITAG>]=LookupValue("OCC_CUST_LOV_SR_3", "Yes") AND [<stCall_Back_Number_ITAG>] IS NULL)

How to bind JTable row height to the maximum height of a the columns

Suppose i have a JTable. data setup is done. Thing is whenever data font size increases table row height should change. How?

Add a PropertyChangeListener to the table to listen for a font change event. Then use the setRowHeight() method of the table.

JTable row background change - based on EXTERNAL event

Greetings folks!
I'm hoping for some help with a JTable issue. Here's the scenario:
The app is a point of sale application. The user scans or manually adds an item to the order, which causes a row to appear in the JTable displaying description, price, quantity, etc. The user can then right click a row on the JTable and select an option from the popup menu. If the user selects one of the options, I want to be able to change the background color on that row.
EVERYTHING I've seen online and researching is based on adding a custom renderer to the jtable which changes the background based on the data in the row. In my case there isn't anything in the row which changes... hence the point of changing the color.
What I'm looking for is a method which will let me change the background of row x. I'm guessing there isn't a way. I'm hoping someone has a suggestion.
Thanks in advance,
John E.
PS: I'm fairly new to java and working with inherited code, so please no 'you need to redesign the world' type answers unless there's an easier way. :)

In my case there isn't anything in the row which changesThen how is the table going to know what color to paint the row? Remember painting the row is a dynamic process. You can't just paint it once. You need the ability to repaint the row if for example the table is scrolled and the row is now longer present. Then when the table scrolls again and the row is present you need to be able to repaint the row in your specified color. This means you need some way to tell the table what color the row should be. Which means you need to keep that information somewhere.
One way to do this is to store the data in the TableModel that indicates that this row should be painted a "different" color. Then your situation is like the examples you have found. You now have some data you can test. This column does not need to be visible in the table since you can remove the TableColumn from the TableColumnModel so the column is not painted.
Here is a simple posting that shows a better approach to painting row backgrounds withouth using a renderer:
