Problem on JTable Sorting
Hi,
I am using JDK1.6 and I am using the predefined sorter function for sorting the JTable, here I am getting the trouble that My JTable get the Table List from a server, when ever I connect to the server its giving me the list of records, after that if I disconnect the rows are getting removed after that if I am again connected to the server the list is not displaying but its updating. If I remove the sort method its working fine..... Why, its happening like that I am not getting.
Please, Help to resolve this issue.
Thank u,
Sarikakiran

I have a table with some entries. The table is a sortable one. I use the standard TableMap.java and TableSorter.java for sorting. The initialisation part consists of the following lines:
TableSorter sorter = new TableSorter(myTblModel);
JTable table = new JTable(sorter);
The problem I have is when I sort the table using the table column header, the rows gets sorted properly. However when I use getValueAt method to retrieve an object at a specified location, it always returns the object that was there before sorting. I dont know where am I going wrong? Can anyone help me please?
TIA,

JTable sorting - problem when adding elements (complete code inside)
I�m writing this email with reference to a recent posting here but this time with the code example. (I apologize for the duplicated posting � this time it will be with the code)
Problem: when adding more elements to the JTable (sorted) the exception: ArrayIndexOutOfBoundsException is thrown.
Example: If the elements in the table are 10 and then the user requests for 8 � the table will produce the correct result. However, if the user will ask for 11 items (>10) the exception will be thrown.
The program: The program below (compiles and running). A JTable is constructed with 3 items, when you click the button - the return result should be 4 items - this will generate the error, WHY?
I would highly appreciate your thoughts why this is happening and most importantly � how to fix it.
Thanks a lot

}The table listens to the TableModel for changes. Changing the table by adding/removing
rows or columns has no affect on its table model. If you make changes to the table model
the table will be notified by its TableModelListener and change its view. So tell
MyTableModel about the change of data:
public class TableSorterDemo implements ActionListener
MyTableModel tableModel;
public TableSorterDemo()
defaultListModel = new DefaultListModel();
init1();
tableModel = new MyTableModel(defaultListModel);
TableSorter sorter = new TableSorter(tableModel);
public void actionPerformed(ActionEvent ae)
if (ae.getSource()==clickMe)
defaultListModel.removeAllElements();
init2();
tableModel.fireTableStructureChanged();

Believe me when I say I have read the forums and the tutorials and the API and still I cannot
sort my JTable. Just a simple sort on the first column is all I want to do. I am using the default table model and I have the TableSorter and TableMap classes from the tutorial.
This is my set up:
tm = new DefaultTableModel(tc,th); //tc is a vector of rows, th is a vector of col headings
sorter = new TableSorter(tm);
addrTable = new JTable(sorter);
I think my biggest problem is how to call the TableSorter method. When I use: TableSorter.sortByColumn(0); I get the error... non-static method cannot be referenced from static context. When I try just sortByColumn(0); of course the compiler cannot resolve symbol.
What do I do?not sure if this will work as i haven't tried it, but i think you'll need to make a call to the sorter.sortByColumn(int, boolean) method. retrive the column index the same way you placed the data in that cell or from a call to :
TableColumnModel columnModel = tableView.getColumnModel();
int viewColumn = columnModel.getColumnIndexAtX(e.getX());
from the point where your cursor is.
if you do that right after your edit of the cell (where you should be able to get the column index) and also pass in the boolean ascending or descedning value it should sort post-edit.
again i haven't tried it, and thats just by looking over the code...
worth a try though... hope it makes sense...

I have a problem regarding sorting a JTable. Using the autoCreateRowSorter method, the JTable sorts fine visually since the table is only displaying strings, but actually selecting an item in the table causes problems. The Table Model itself stores a Plugin object and on each row displays attributes from a Block object stored in a list. When I double click on a row using the mouse click listener, I want to grab the Block for the row that was clicked. The way I am currently doing this is sending the int for the selected row through the table model to the plugin and then grabbing the block from its list at the index. Of course this doesn't work when the table has been sorted because the order has changed visually but not in the list. Does anyone have any good ideas for fixing it? If there is some way that the Plugin could listen for the table being sorted and know which column was sorted and in which direction, that would work great, otherwise I can not figure out how to attack this problem.

Hello,
i have a selection problem with JTable. I want to allow only single cell selection and additionally limit the selection to the first column.
I preffered the style from MS Outlook Express where you can select the email accounts to edit.
It is a table like this:
Account name | Type | ...
--------------|---------|---------------------
Hotmail | POP3 |
GMX | IMAP |The selection should be only avaibable at 'Hotmail' or 'GMX' - not at 'POP3', 'IMAP' or as complete row selection.
Please help me!
Thanks.

I want to sort and Filter JTable.
Sample code is avialable for this ?.
Also i would like to know about 3rd party classes.
RenjithHi,
There is a such sample on the tutorials for swing/JTable. In this tutorial, u will find 2 files and then make the corresponding classes :
TableMap and TableSorter
u can use them like this :
TableSorter sorter = new TableSorter(myModel);
//JTable table = new JTable(myModel); //OLD
JTable table = new JTable(sorter);
sorter.addMouseListenerToHeaderInTable(table);
It is very simple, and you can easily modifie these classes to add filters..
Regards, JFB -
Problem with alphabetised sorting
So your sorting system only recognises the first digit and this causes problems, for example sorting files starting with 1 to 12. Instead of getting a list of 1,2,3....12 you get 1,10,11,12,3,4,5....9.
Frustrating to say the least.I think the issue is in the iOS system for sorting which Reader uses. Rename your files 01, 02, 03...

Good to know! OS 9.1 is my favorite OS to date. Tiger & SL running in close 2nd.
Me personally, I will not upgrade until OS 10.9.02 is released. -
Colum Resizing problem in JTable
HI All,
I am facing a problem with JTable while resizing the colum. when user clicks and drags to resize a column, the column width increases continuously till the mouse button is released. I am sure this sounds like a vague description,
(eg)
when I click on a column boundary and drag, the column width is getting increase beyond where the cursor of the mouse is. In a normal table, when I click and drag, the column resizes to the size that I have the mouse position at, and gets set to the width when I release the mouse. But right now, when I click the mouse and drag to say a width of 50 from 10, it is still increasing beyond 50 and stops when I release the mouse at about 100 or higher. I hope this is a clearer explanation.
In Java 1.2, it works fine. but in java 1.4...
If Anyone knows, please let me know
Advance thanks for any comments and suggestion..
Best Regards,
MuthuI solved this problem... Problem is getPreferredSize() method. I override this method
Thank u for ur suggestion..

Problem of JTable's column setPreferredWidth.

I have a problem about JTable,I want to set the preferredwidth for every column when the table is first established,but it is always failed.
Could someone tell me the root?Thanks!

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------Don't forget to use the Code Formatting Tags so the posted code retains its original formatting. That is done by selecting the code and then clicking on the "Code" button above the question input area.
The problem is that the size of the frame is greater than the size of the table so the widths of all the columns get adjusted after you specify the original default size.
Your code should be something like:
typeTable.setPreferredScrollableViewportSize(typeTable.getPreferredSize());
JScrollPane typeTableScrollPane=new JScrollPane(typeTable);
mt.pack();
mt.setVisible(true);Or you might be able to use my [Table Column Adjuster|http://www.camick.com/java/blog.html?name=table-column-adjuster] which will resize the columns automatically. -
HI,
I have a problem in JTable.I have a Jtable and a button named validate.My JTable first displays a set of rows and colums.if we name the colns as a,b and c. when i click the validate button i will take the values of a1 and b1 and do some validations. If it is in correct position then the row remains as it is else i will change the value of b1 to a1 position and vice versa. This happens in a loop till the end and the data vector of the table gets changed accordingly.Now the problem is suppose if there are 10 rows and the value changes in row 1,5,7 thn i need that rows alone to be colored while the button ends its action.Finally the JTable should be viewed as row 1,5,7 colored and others in their default color....
Please help me...

Hi All,
I am facing some problems in JTable :
1) How to remove all lines between cells, neither i should have column nor row lines....there should not be any lines between any cell at all.
2) If i select a perticular cell, complete row is getting selected with a blue background, that should not happen at all.....row should not get select....
3) How to make a cell non editable.
Regards,
Ravi1) Read the API. Check out the set??? methods until you fine what you want
2) Read the API. Check out the methods that deal with row and column selection
3) Override isCellEditable(...) method of JTable or DefaultTableModel
