Jtable column title

I want to sort a JTable by clicking a column title
(sort according to that column's values)
I thought about adding an actionListener to the titles
and then sort my data Vector and use fireTableChanged().
is there a better way, does a JTable have a method to do it on it's own ?

i like how you show people's incompetence by replying with links to their answers all the time.

Making JTable columns titles visible

Hello,
Can you give me the magic call that will show my JTable with
columns titles at top of it? Currently, it shows only regular
cells, but not titles.
Please, help. Thanks in advance,
Olivier

Another question which will be no problem for you.
Do you know of a java method to get the memory
footprint of the current
process.
I try to perform some memory consumption analysis for
my data model
written in java and I would like to measure this
consumption.Sorry, don't know much about that. I'd post this separately in another forum if I were you.

F2 key not working with custom JTable Column

I have a custom JTable Column (which is a JPanel with a JTextfield and JButton). Everything works as expected, except when the user presses "F2" to start editing the custom column cell. When the user presses F2, the custom cell goes into editing mode, but I am unable to type anything in it.
Below is the SSCCE.
Steps to Reproduce problem:
1) Run the Program
2) Select any cell in first Column.
3) Press "F2" and try to type into the cell. Can't type anything.

regards,
nirvan.

The F2 key when pressed generates an action event (either JTable generates it or some other component). I am not sure how to handle the action event in the isCellEditable() method. Also, F(X) range of keys other than F2 dump some junk character in the JTextfield when pressed. I am now stuck at this point and don't know how handle F(X) range of keys.

How to make the column title needs to be on each page?

If a document has more than one page than a column title needs to be on each page,I can use Word fuction to do that. But If I Only use XML publisher, How to do it.

Hi
If you mean how do you repeat the column titles on a table if the table extends over several pages then all you need do is:
Highlight the table header row
Right click and select table properties
On the Row tab, specify that the header row should be repeated on every page
Save your work
XMLP will now respect the word setting and will repeat the header row on evey page the table needs.

I feel that drafted sql is very shaky and it needs the SQL Server XML experts to modify to make it work for me. Please kindly help, exam the coding of my shcXMLTableValidate1.sql and modify it to work.
Thanks in advance,
Scott Chang

Hi Scott,
2) Yes, FOR XML PATH clause converts relational data to XML format with a specific structure for the "marvel" Table. Regarding validate all the avenger_names, please see below
sample.
DECLARE @x XML
SELECT @x=(SELECT ID ,avenger_name FROM marvel FOR XML PATH('Marvel'))
SELECT @x
SELECT
n.value('avenger_name[1]','VARCHAR(99)') avenger_name,
n.value('ID[1]','INT') ID
FROM @x.nodes('//Marvel') Tab(n)
WHERE n.value('ID[1]','INT') = 1 -- specify the ID here
--FOR XML PATH('Marvel') --uncommented this line if you want the result as element type
3)i.check the xml schema content
--find xml schema collection
SELECT ss.name,xsc.name collection_name FROM sys.xml_schema_collections xsc JOIN sys.schemas ss ON xsc.schema_id= ss.schema_id
select * from sys.schemas
--check the schema content,use the name,collection_name from the above query
SELECT xml_schema_namespace(N'name',N'collection_name')
3)ii. View can be viewed as virtual table. Use a view to list the XML schema content.
CREATE VIEW XSDContentView
AS
SELECT ss.name,xsc.name collection_name,cat.content
FROM sys.xml_schema_collections xsc JOIN sys.schemas ss ON xsc.schema_id= ss.schema_id
CROSS APPLY(
SELECT xml_schema_namespace(ss.name,xsc.name) AS content
) AS cat
WHERE xsc.name<>'sys'
GO
SELECT * FROM XSDContentView
By the way, it would be appreciated if you can spread your questions into posts. For any question, feel free to let me know.

Using mathematical symbols in column titles -can't get it to work!

Hello all,
I am trying to use greek mathematical symbols in my column titles, ( Δ delta, ά alpha etc)
There is obviously some character set conversion problem/I need greek alphabet as the symbols are output as question marks on my JSP pages.
Does anyone know how to fix this please?
(I am setting the label text in the control hints section of the view object editor)
Thanks,
Louise

Include the Symbol you want in the control hint as an HTML encoding e.g &delta; or &#948;
Then in the page, go to the JSTL tag that displays the ${bindings[column].label} set the escapeXML attribute to false.

How to catch selected text in JTable Column

Hi there,
I am learning JTable. Need help for How to get the selected text from the JTable Column which is set to be editable.
for example in JTextFiled you have method on getSelectedText(), is there any method for tracking the selected text.
Thanks in advance
Minal

Here's an example of the model I used in my JTable. Not the "getValueAt" method & "getRecordAt" method. You will have to have a Record object - but it only contains the attributes of an inserted record (with appropriate getters & setters). Hope this helps.
public class FileModel5 extends AbstractTableModel
public boolean isEditable = false;
protected static int NUM_COLUMNS = 3;
// initialize number of rows to start out with ...
protected static int START_NUM_ROWS = 0;
protected int nextEmptyRow = 0;
protected int numRows = 0;
static final public String file = "File";
static final public String mailName = "Mail Id";
static final public String postName = "Post Office Id";
static final public String columnNames[] = {"File", "Mail Id", "Post Office Id"};
// List of data
protected Vector data = null;
public FileModel5()
data = new Vector();
public boolean isCellEditable(int rowIndex, int columnIndex)
// The 2nd & 3rd column or Value field is editable
if(isEditable)
if(columnIndex > 0)
return true;
return false;
* JTable uses this method to determine the default renderer/

Xml search and replace for 'Session Variables' in column title view

Hi Experts,
I have around 10 reports where measure column titles are displayed based the session variable.
Below is the syntax I have used in the column title
@{biServer.variables['NQ_SESSION.VariableName']}
Now I would like to replace the above syntax with some static text. To do this, I am trying to use the xml search and replace feature in the catalog manager.
For some reason, catalog manager is unable to find the syntax in the xml file. I have tried using escape character also for the apostrophe by using &apos, but no luck.
Any pointers on how to replace the text?
Thanks

Using Analysis get the xml conversion for @{biServer.variables['NQ_SESSION.VariableName']} from Advanced tab's xml code
use this code to find in catalog manager, if you able to find then go for search and replace option.
I think this should work for you.

Export JTable Column headers to Excel document

Hello all!!! I am having a small problem while trying to export some data from a jTable to an excel document.
I have a jTable and I use a custom TableModel with this:
private String[] columnNames = {"First", "Second", "Third", "Forth"};as names for each column of the table.
The thing I am trying to do is to export exactly the same "headers" from the columns of the jTable to the excel spreadsheet using Jakarta POI. Unfortunately I don't know how to do it and I haven't found anything yet on this forum. Can anyone help me with this?
In simple words I want to know how I can have the same headers from my jTable columns, with the headers from the excel doument I will create.
Many thanks in advanve!!!
Kostas

Thank you for your reply first of all. The problem is how to get the heading text and how to put it to the excel's first row OR to excels "headings" (if it is possible...). [in other words replace A,B,C,D from the excel document with the headers I get from the jTable...] .
I hope now you can see what I am looking for... If there is no solution to this please tell me what are the alternatives. (B) could be a good example.
Thanks you very much!!

Custom JTable column (JCheckBox) not included in row selection.

I am trying to use JCheckBox (for display only data) as one of my JTable columns. I have written custom cell renderer for the same. Every thing is working fine except that when I select a row, the new custom JCheckBox column is not included in selection. Here is the code that I am using.
    protected class CheckBoxColumnRenderer extends DefaultTableCellRenderer {
        JCheckBox ckb = new JCheckBox();
        public Component getTableCellRendererComponent(JTable table, Object value,
                    boolean isSelected, boolean hasFocus, int row, int column) {
            if (value instanceof Boolean) { // Boolean
              ckb.setSelected(((Boolean) value));
              ckb.setHorizontalAlignment(JLabel.CENTER);
              ckb.setBackground(super.getBackground());
              if (isSelected || hasFocus) {
                  ckb.setBackground(table.getSelectionBackground());
            return ckb;
    }How can I include the custom cell in the row selection.

nirvan.

they have lots of dependencies and it is not always easy to strip out an SSCCE without a considerable effort.Exactly. And is the cause of the problem the dependencies or something else. The only way to know for sure is to strip out the code and simplify the problem, that way you truly understand what the problem is.
The majority of time this can be done with minimal effort as in this case.
Some times we are sure that the problem is with certain part of the code Is the problem the code or the way the code is invoked? How do we know the TableModel is created properly or that the column class is overwritten correctly when we can't see it?
someone having a third look at it may actually find the enhancement required with ease.Exactly, but we need to see the big picture.
So are you sure that I should post an SSCCE with every possible question where coding is involved ?In the majority of cases a SSCCE is easily created in 5-10 minutes, so if you want the fastest help then yes.
Just twice this past week I was ready to ask a question on the forum and was preparing a SSCCE to post and sure enough both times the creation of the SSCCE caused me to look at the problem differently and I solved it. I would much rather solve a problem on my own then post a question and wait for hours (days) hoping someone else knows the answer.

What method should be used for resizing the particular JTable Column width

I have a four table. Only one table which are on top have a table header. I want that when user resize the topmost table with a mouse other table colume also be resized automatically. So I want to know that what method should be used for resizing the particular JTable Column width.
Thanks
Lalit

maybe you can implement a interface ComponentListener as well as ComponentAdapter with your topmost Table.
for example:
toptable.addComponentListener(
new ComponentAdapter(){
public void componentResized(ComponentEvent e){
table1.setSize(....);
table2.setSize(....);
/*Optionally, you must also call function revalidate
anywhere;*/
);
