Regarding Jtable

Hi
I have created a jtable with default table model and rendered its first cell as a JButton with lable "+"
I have written an action listener for the button click event which does some action and set the label of the button "-" .
Its working well ,the action associated with the event is done but the button label is still "+"
I am able to see the chane in label only when the column is resized....
can please anyone help me out
its urgent
i want the button lable to be changed without resizing....
Thanks in advance

The renderer for a table cell is only a rubber stamp used to display the cell. It isn't a component placed on the screen. Changing the component (the button) doesn't make it display on the table. You have two problems. The first is that you need to get the button to redisplay. fireTableChanged() was a good idea, but it's really overkill. Try using fireTableCellChanged(int,int) (I think). Next, you need to get your button to know if it should display a '+' or '-'. That data needs to be stored somewhere (usually in the tablemodel). For example, your first column could be a Boolean in the tablemodel, but displayed as a button. Or your renderer could look at another column (table.getValue(row, othercolumn)) to see how it should display.
Buttons might not be a good idea in tables. You can't add a listener to them because they are just displayed (rubber stamp). You can use one, but the listener should be on the table, not the button.

I meant that the laptop freezes in gdm and in console (tty1). In gdm i can't even type any character. And in console i can login but when i press the tab key (autocompletation) it stops. The only thing i can do is press the power button.
Actually my keymap is es_ES. And i think that it's working fine because the n tilde and pipes work fine.

Wrong use of rows/columns. Try like below:
for ( int i = 0; i < colCount; i++ ) {
     m_rows    = new Vector();
     for ( int z = 0; z < rowCount; z++ ) {
          m_rows.add(stm.getValueAt(i,z) );
     // Vector of vectors.
     m_rowValues.addElement(m_rows);
}You weren't so far from it ;-)

Help regarding JTable in Java Swing

hi,
i m confused regarding JTable in Swing. i hav added a JTextField in a cell of a JTable. i hav attached a kay listener with that textfield . But when i m selecting that cell ,where i hav added that textfield with a single click and typeing any key i m not getting that keyevent. But when i m selecting the same with a doulbe click and typing any thing i m getting that event .
can any one tell me why the discrepency taking place. that textfield is
there in that cell .then how it does make any difference with a single and double click.
regards

i hav added a JTextField in a cell of a JTableYou don't add a text field to a cell in a table. You add a text String to the TableModel. When the user double clicks on the cell an 'editor' is invoked and the text is copied to the editor (which by default is a JTextField). So the KeyStrokes go to the editor text field.
When you just single click on a cell the table still has focus, not the editor, to the KeyStroke character is passed directly to the text field without the text field actually getting focus.

Regarding JTable selection

Hi,
I did one non-editable JTable. If I press "F2" button on selected row of that table, It's throwing following exception on console. Please try to provide solution for me.

Need Help regarding JTable Sort?

Hello friends, i am working on the JTable and want to sort it by clicking on header of the column. I am using jdk1.5 and as my project is based on it so i cant change the jdk. I dont have the rowsorter class in jdk 1.5. So Is there any way through which i can sort the the Jtable by clicking its column header.
Thanks for any help.

Here is a link to the 1.5 Swing tutorial:
https://www.cs.auckland.ac.nz/references/java/java1.5/tutorial/uiswing/TOC.html
The Table section has a sorting example.

Threads regarding JTable

I want to add checkboxes to each cell of a row.in Jtable. At the same time I used DefaultTableModel to insert rows from database.
Checkbox are implemented using, AbstarctTableModel.
Can I use both these table models in one class?
Edited by: DHURAI on Jul 29, 2009 3:07 AM

Thank u for ur reply.
TableColumn table = jTable1.getColumnModel().getColumn(2);
table.setCellEditor(new DefaultCellEditor(Checkbox));I used the above code to add checkbox in cell of table. Instead of showing checkbox, it shows true or false.
The checkbox arrives and disappears for mouse click only and the value true or false also gets changed. What I have to do, to retain the checkbox format as it, instead of text message as true/False?

Regarding setValueAt method in JTable

sir,
i have a problem regarding JTable.
now if u enter the data in cell
then setvalueAt() method is called once
now if u enter the data in a cell which is already
having a dat in that cell, then the setvalueAt method
is called twice.........
why it so and how can i prevent it as i needed it in
getting dataVector and when i print the values of dataVactor
it gives recent values not the previuos set values
i m just beginner in this concern
i hope u be able to understand and solve
thanks in advance

Hi,
I have looked at your code. You are still trying to control too much yourself. Let the table do it instead. The table is designed to handle all of its events and works best when you let it. I made a few code suggestions here. I didn't compile it, so please don't expect it to just work. It is merely a suggestion of an approach that may make your work easier.
Vector tableData = new Vector();
ArrayList newValues;
ViewModel ()
    // in the constructor create an ArrayList for each row that will be displayed
    // and put them in the tableData Vector
    int count = newViewFrame.sortCombo.getItemCount(); // Count is the number of rows?
    for(int i=0;i<count;i++)
      newValues = new ArrayList();
      for (int j = 0; j < numColumns; j++)
        newValues.add();
      tableData.add (newValues);
// These methods are used by the table and should be supplied
public int getRowCount ()
{ return tableData.size(); }
public int getColumnCount ()
{ return 5; }   // the number of columns in your table - this number is used a lot
                  // do not make it complicated to compute
public void setValueAt(Object value,int row, int col)
    //super.setValueAt(value,row,col); - No point, this is an empty method
    // if the index is out of bounds or nothing was changed return
    if (row < 0 || row >= getRowCount())
      return;
    if (o == null)
    { return; }
    // get the data array for the row which was changed
    newValues = (ArrayList)tableData.elementAt (row);
    // it doesn't look like your are doing anything for columns 1 -4 ?
    if (column == 0)
      return;
    if (column == 1)
      return
    else if (column == 2)
      return;
    else if (column == 3)
      return;
    else if (column == 4)
      // not first - do this after you have changed the array
      // fireTableChanged(new TableModelEvent(this,0,4,4));
      Integer colValues[] = TableComboBoxEditor.getColumnValues(((ViewModel)newViewFrame.viewTable.getModel()).getDataVector(),col);
      int retrunValue = alreadyExists(colValues , value);
      System.out.println("the value of row is "+retrunValue);
      if( retrunValue != Integer.MIN_VALUE && retrunValue != row)
        System.out.println("heyheyeheyeheye");
        Set setOfRows = TableComboBoxEditor.hash.keySet();
        Iterator iterator = setOfRows.iterator();
        setValueAtCalled=true;
        int count = newViewFrame.sortCombo.getItemCount();
        // newValues = new ArrayList(); use the one from the dataVector
        for(int i=0;i<count;i++)
          newValues.add(newViewFrame.sortCombo.getItemAt(i));
        // while(iterator.hasNext()){
        // setValueAt(new Integer(0),((Integer)iterator.next()).intValue(),col);
        validatingRemainingColumns(iterator,value,row);
        setValueAtCalled = false;
      // now refresh the table
      fireTableChanged(new TableModelEvent(this,0,4,4));
// this method creates Integers to set the values in the table
// If you want Strings instead change it
public Object getValueAt (int row, int column)
    if (row < 0 || row >= getRowCount())
      return " ";
    newValues = (ArrayList) tableData.elementAt (row);
    if (column == 0)         // set number
      return new Integer (newValues.get(0));
    else if (column == 1)
      return new Integer (newValues.get(1));
    else if (column == 2)
      return new Integer (newValues.get(2));
    else if (column == 3)
      return new Integer (newValues.get(3)));
    else if (column == 4)
      return new Integer (newValues.get(4)));
    else if (column == 5)

[Feature request] Runtime width of JTable columns based on attribute settings

I'm wondering if it's possible to let 'JClient' dynamically resize the columns in a JTable. Eg: I have set the width of some attribute of some ViewObject to 3. But when I run the application all columns are equally sized. I tried changing the JTable's property autoResizeMode (figuring it might override settings by JClient), but that doesn't seem to have any effect.
Also, 'grabbing' a column from the table through some manual coding and setting the width of that column doesn't seem to work either.
I've posted something regarding JTable Re: for specifically RIZWAN from PAkistan or anyone, but I'm curious to know if this 'Specialised editor for Grid Control (JTable)' that Grant Ronald spoke of, will include some sort of applicable functionality.
It's clear that we need some better (that is, 'any' ;)) way of manipulating columns in a JClient table.
Any comments?
Thanks.
Arno

We are currently looking into that.
The column width should not be controlled from the model, it is a setting on JTable, We are considering providing a JClient control (JUTable ??), which is a JTable in a scrollpane and give you more power over column width, column headers etc....
We are currently evaluating that.
It would mean that you've got a table control with properties allowing you to set these things on the control itself.
Currently you have to set the hints on the TableColumn.
Here is an example :
tableDeptView1.setModel(JUTableBinding.createAttributeListBinding(panelBinding, tableDeptView1, "DeptView1", null, "DeptView1Iter", new String[] {"Deptno", "Dname", "Loc"}));
tableDeptView1.getColumn("Deptno").setMaxWidth(75);
tableDeptView1.getColumn("Loc").setPreferredWidth(200);
tableDeptView1.getColumn("Loc").setMinWidth(100);
tableDeptView1.getColumn("Loc").setMaxWidth(450);

JTable issues

I'm using JDK 6 and i would be glad to get answers to the following regarding JTable?
1) I am using setAutoCreateRowSorter(true) to enable sorting of my JTable columns.
When i have a sorted column which is editable, how can i prevent the column from getting automatically sorted while editing.
It should only get sorted when the column header is clicked.
Sort the score 1 column of my sample code and try to edit a cell, u'll get the picture of what i mean.
2) While editing JTable, when i press tab or enter, i want the selected cell to clear its contents when i type in a value.
I've tried searching the forum but haven't got a solution. Any forum link that would help is welcome.
Thanks

JTable How to align the Text in a Cell to Centre

Hi Plese Help regarding JTable.
I want to align the Text in the Table Cell to Centre how to align it. Im using Abstract Data Model TAble an what is the meaning of renderer and its use.. Help me out

Here are a couple of links you should read for information on tables and renderers:
http://java.sun.com/docs/books/tutorial/uiswing/components/table.html#editrender
http://www-106.ibm.com/developerworks/java/library/j-jtable/index.html?dwzone=java
Here is an example of a simple renderer that will:
a) center the text
b) highlight the background when the cell gets focus

Removing row and collumn in JTable

guys i have problem regarding JTable.. ive tried to search over the forum to find suitable answer but nothing fits in....
i need to refresh my JTable but i cant....
i've tried validate(), repaint() but it doesnt seem to work properly.
this is the portion of my code that generate the JTable
public void getTable()
          Statement statement;
          ResultSet resultSet;
          try
               String query = "SELECT * FROM Booking ";               statement = con.createStatement();
               resultSet = statement.executeQuery(query);
               displayResultSet(resultSet);
               statement.close();
          catch(SQLException sqle)
               sqle.printStackTrace();
     public void displayResultSet(ResultSet rs) throws SQLException
          boolean moreRecords = rs.next();
          if(!moreRecords)
               JOptionPane.showMessageDialog(this,"Data not found !","Information Message",JOptionPane.INFORMATION_MESSAGE);
               return;
          Vector columnHeads = new Vector();
          Vector rows = new Vector();
          try
               ResultSetMetaData rsmd = rs.getMetaData();
               for(int i = 1; i <= rsmd.getColumnCount(); ++i)
                    columnHeads.addElement(rsmd.getColumnName(i));
                    do
                         rows.addElement(getNextRow(rs,rsmd));
                    }while(rs.next());
                    table = new JTable(rows, columnHeads);
                    table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
                    table.setFont(new Font("Arial",Font.BOLD,10));
                    JScrollPane scroller = new JScrollPane(table,JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
                    gbConstraints.fill=GridBagConstraints.BOTH;
                    addComponent(scroller,4,1,4,4); // i use gridbaglayout
          catch(SQLException sqle){
               sqle.printStackTrace();
     public Vector getNextRow(ResultSet rs, ResultSetMetaData rsmd) throws SQLException
          Vector currentRow = new Vector();
          for(int i = 1; i <= rsmd.getColumnCount(); ++i)
          switch(rsmd.getColumnType(i))
               case Types.VARCHAR:
                    currentRow.addElement(rs.getString(i));
                    break;
               case Types.INTEGER:
                    currentRow.addElement(new Long(rs.getLong(i)));
                    break;
               default:
                    System.out.println("Type was: "+rsmd.getColumnTypeName(i));
          return currentRow;
when i pressed a button this method will execute again but will show the new updated query if it the database have allready been updated. i tried to validate and repaint but it doesnt work...
can some one out there tell me how to perform such task ?

ive tried to search over the forum to find suitable answerJTable is a Swing component and there is a forum for Swing questions. Maybe if you searched the Swing forum (and posted your question there) you would have had better results.
Here's an [url http://forum.java.sun.com/thread.jsp?forum=57&thread=504709]example (from the Swing forum) that shows how to repopulate a JTable by resetting the DataModel of the table with new data.

Refreshing JTable (JDBC)

Hi there!
I would like to ask your help regarding JTable.
I am just new in Java comming from VB. I really cannot understand how JTable works.. since in VB it is very easy to refresh the table/grid.
Any one who got a simple program (Even using MS Access) that will display DB Table's content to a JTable object and will be able to refresh JTable's content everytime a record is updated? (Even the refreshing of table side only).
Hope you guys can help me with this since its been weeks already looking for a sample and explanation which is easy to understand.
Thanks!

have you tried sun's tutorial: http://java.sun.com/docs/books/tutorial/uiswing/components/table.html ?
JTable is implemented with a data model (table model) as its data container.
So you need to update the table model first before re-displaying your table. :)

JTable editCellAt

Hello Javaers,
I've a question for you regarding JTable edits - hoping to save some google time.
I've a JTable that currently accepts edits by careful overriding of the standard methods, isCellEditable, and by specifying
((DefaultCellEditor)table.getDefaultEditor(String.class)).setClickCountToStart(2); I'd like to disable click-edits at this point, and move the edit function to a context menu. How do I disable click editing?
Thanks!

Hey Camickr,
thanks for checking in as always. I actually discovered what was going on, it had me just as confused as you might have been by my post. I was firing the editCellAt from a JPopupMenu (as a context-menu action). I was puzzled when I saw that the edit wasn't occurring.
Turns out that it was indeed occurring, just that the disposal of the context menu probably momentarily stole focus from the edit, which was canceling the edit itself. I had to explicitly call dispose before initiating the action, and this solved my problem.
Thanks - I'll mark it as solved so that you can get some points.
Cheers!
Alex

Updating multiple records

Hi,
Im having issues with updating multiple records.
This query selects users in a specific unit that are inactive (ui.nf_statusid = 2) and compare it newsmail_recipient table
select *
                    from roleuser ru, unit u, userinfo ui
                    where u.ip_unitid = ru.nf_unitid
                    and u.ip_unitid = unit_id
                    and ui.ip_userid = ru.nf_userid
                    and ui.nf_statusid = 2
                    and n_internal = 0
                    and ui.ip_userid in (select user_id
                                               from newsmail_recipient
                                              where user_id = ui.ip_userid
                                                and nf_listid = liste
                                                and nf_statusid = 1;the second script will set the users to inactive in newsmail_recipient that are inactive in the userinfo table.
update newsmail_recipient
             set nf_statusid = 2
              , d_modified = sysdate
             where user_id = ui.ip_userid;I would like to know if its possible to merge this query. I know its possible for insert but havent tried update before.
This is how i do it, but its not working.
case when (select *
                    from roleuser ru, unit u, userinfo ui
                    where u.ip_unitid = ru.nf_unitid
                    and u.ip_unitid = unit_id
                    and ui.ip_userid = ru.nf_userid
                    and ui.nf_statusid = 2
                    and n_internal = 0
                    and ui.ip_userid in (select user_id
                                               from newsmail_recipient
                                              where user_id = ui.ip_userid
                                                and nf_listid = liste
                                                and nf_statusid = 1)
        then update newsmail_recipient
             set nf_statusid = 2
              , d_modified = sysdate
             where user_id = ui.ip_userid;
