help please

Look at the line causing the error and place several System.out.println's in this region. You'll see that you're trying to remove items from a vector (the tablemodel) that don't exist.

Why do you have a for loop there anyway?

[rajasohaibmaroof]

i have this for loop there because i was just trying different options given in one site .are u suggesting that i dnt have a row there ?? but i have a row there when ckick on the button in shows that i have clicked on a particular row and when i pass this row as an argument in remove row it gives me error. i should be deleting it i do not know how to solve this problem can u please suggest me what should i do there

[Fubarable]

i have this for loop there because i was just trying different options given in one site .

And this is the danger when you borrow code without understanding it. You shouldn't do this.

are u suggesting that i dnt have a row there ?? but i have a row there when ckick on the button in shows that i have clicked on a particular row and when i pass this row as an argument in remove row it gives me error. i should be deleting it i do not know how to solve this problem can u please suggest me what should i do there

No, I'm suggesting that you write your own code and think through what you want it to do. That for loop has no logical reason for being there. How you write your code is up to you and will depend on your needs.

If you need more specific help, consider creating and posting an SSCCE that we can run and modify.

[Fubarable]

You know that you are creating more than one ButtonEditorTest objects, right? One that is displayed, and created here:

   public static void main(String[] args) {
      final JFrame f = new ButtonEditorTest();
      f.setDefaultCloseOperation(EXIT_ON_CLOSE);

      EventQueue.invokeLater(new Runnable() {

         public void run() {
            f.setVisible(true);
         }
      });
   }

And one that is create in a JButton's handler here:

   private void buttonPressed(JTable table, int row, int column) {
      JOptionPane.showMessageDialog(table, "Pressed at " + row + "        "
            + column);
      ButtonEditorTest bet = new ButtonEditorTest();
      bet.selectedCol(row);
   }

This second ButtonEditorTest serves no purpose other than to contribute to your error. Trying to remove a row of a non-displaying JTable doesn't make sense. Why not remove the row the JTable that is actually being shown?

[Fubarable]

I would get the original ButtonEditorTest object and call my method on it:

   private void buttonPressed(JTable table, int row, int column) {
      JOptionPane.showMessageDialog(table, "Pressed at " + row + "        "
            + column);

      // !!
      ButtonEditorTest btnEditorTest = (ButtonEditorTest) SwingUtilities
            .getWindowAncestor(table);
      btnEditorTest.selectedCol(row);
      //!! ButtonEditorTest bet = new ButtonEditorTest();
      //!! bet.selectedCol(row);
   }

I would make sure that the DefaultTableModel I'm working on is the same one as is being displayed in the JTable:

public class ButtonEditorTest extends JFrame {
   //!! JTable jTable1 = new JTable();
   
   //!!
   private DefaultTableModel defaultTableModel = (new DefaultTableModel(
         new Object[][] { { "asdf", "asdf", "asdf", "Delete", "Update" },
               { "asdf", "asdf", "asdf", "Delete", "Update" },
               { "asdf", "asdf", "asdf", "Delete", "Update" },
               { "asdf", "asdf", "asdf", "Delete", "Update" } }, new String[] {
               "Sr.no", "Book Title", "Author Name", "Delete", "Edit" }));
   private JTable jTable1 = new JTable(defaultTableModel); //!!

   
   public ButtonEditorTest() throws HeadlessException {
      super();

      //!! jTable1.setModel(defaultTableModel);

And I would only delete the row of interest, nothing more:

   public void selectedCol(int row) {
      // int rowCount = defaultTableModel.getRowCount();
      // !! for (int i = 0; i < rowCount; i++) {
      // // defaultTableModel.removeRow(0);
      // defaultTableModel.removeRow(jTable1.getSelectedRow());
      // // System.out.println(i);
      // }

      // jTable1.setModel(defaultTableModel);
      defaultTableModel.removeRow(row);
      System.out.println("deleting");
      //defaultTableModel.removeRow(jTable1.getSelectedRow());
      System.out.println("deleted");

   }

private void buttonPressed(JTable table, int row, int column) {
JOptionPane.showMessageDialog(table, "Pressed at " + row + " "
+ column);

// !!
ButtonEditorTest btnEditorTest = (ButtonEditorTest) SwingUtilities
.getWindowAncestor(table);
btnEditorTest.selectedCol(row);
//!! ButtonEditorTest bet = new ButtonEditorTest();
//!! bet.selectedCol(row);
}

i did this thing

public void selectedCol(int row) {
// int rowCount = defaultTableModel.getRowCount();
// !! for (int i = 0; i < rowCount; i++) {
// // defaultTableModel.removeRow(0);
// defaultTableModel.removeRow(jTable1.getSelectedRow ());
// // System.out.println(i);
// }

// jTable1.setModel(defaultTableModel);
defaultTableModel.removeRow(row);
System.out.println("deleting");
//defaultTableModel.removeRow(jTable1.getSelectedRow ());
System.out.println("deleted");

}

this thing too

public class ButtonEditorTest extends JFrame {
//!! JTable jTable1 = new JTable();

//!!
private DefaultTableModel defaultTableModel = (new DefaultTableModel(
new Object[][] { { "asdf", "asdf", "asdf", "Delete", "Update" },
{ "asdf", "asdf", "asdf", "Delete", "Update" },
{ "asdf", "asdf", "asdf", "Delete", "Update" },
{ "asdf", "asdf", "asdf", "Delete", "Update" } }, new String[] {
"Sr.no", "Book Title", "Author Name", "Delete", "Edit" }));
private JTable jTable1 = new JTable(defaultTableModel); //!!


public ButtonEditorTest() throws HeadlessException {
super();

//!! jTable1.setModel(defaultTableModel);

but i do not know how should i do this thing
//!! this mark means that it should be not in the code but when i remove this
JTable jTable1 = new JTable(); than i am not left with any jtable .thank u in advance for so much heelo please help me get through this error ill be very thank full to you sir :( i am desperately looking for help

[rajasohaibmaroof]

i went to dream in code they ask me to create SSCCE i created thios code if you will copy this code to Ur netbeans or eclipse it will run please have a look at it i do not know how to create SSCCE .i created this and i thought that it is SSCCE where as my real code is much more complex than this one .:(

[rajasohaibmaroof]

a for the understanding this goes goes i am just having problem with actionlistner this rest is ok . i and do not think that i would be able to get out of it without your help :( please help me

[Fubarable]

I've already told you what you must do, and if it doesn't work, then yes, create an SSCCE. Also, you never notified us about the cross-posts until Norm forced your hand. Where else have you cross-posted this question? You need to show all links, else many of us will not waste our valuable time on this.

[Norm]

Check the other post. I think it's solved.

[Fubarable]

Check the other post. I think it's solved.

Thanks. I won't waste my time with this one again.

[rajasohaibmaroof]

sorry i it wont happen again thank u a lot for giving me time from your precious time . the problem has been solved . i use various sites just to get it done quickly . u are very nice people indeed. i have this first experience of posting . but can u tell me how should i create SSCCE i think that creating a short program that depicts once problem is SSCCE.what i post above is SSCCE by my point of view . but again what is SSCCE

[rajasohaibmaroof]

ButtonEditorTest btnEditorTest = (ButtonEditorTest) SwingUtilities
.getWindowAncestor(table);

your this post help to solve my original program i am very thank full to you . sorry again . u are very good people
