Vector/Table Deleting Row Problem.

[ocean]

Hi I use Vectors with my Tables. When I Remove a row and then insert a new. It first sends empty rows equal to the number of deleted, before inserting the new one. I use code below to delete rows.

removeOrderButton.addActionListener(new ActionListener(){
             public void actionPerformed(ActionEvent event){
                      int getRow;
                      getRow = handleAllTable.getSelectedRow();
                      handleAllModel.removeRow(getRow-1);
                     }
            });

It´s most likley that i need to update/remove from the vector to ?

Solved it, Had to create a function that removed and refreshed vector and tables. And reset an variable that hold the number of rows that were sent.

Jeez, that sounds like you really abused a TableModel.

Why is that? Please tell me, critique makes me learn new things.

The DefaultTableModel does all that by itself with very little tweaking from you.

Thank you for telling me that, I now found out were the real problem is.
I need to remove 1 from the variable that hold rowcount, when i remove a row.

countAddRows=countAddRows-1;

Why do you have to keep track of that yourself? A DefaultTableModel does all that and more.

kind regards,

Mabey i have made it more difficult then it has to be. Itś like this.

I have a combobox that i can select project to work on. Each project has 2 tables. From the first table ill send 3 column to the 3rd table and from the second table ill send 4 columns. Then i work on the data from the third table and send it to be calculated, and saved.

I need to keep track on how many rows and so on i send. Mabey there is a better way to do it. And I will take a look at it. Remember Im just a few month old with Java. But I will start school 25 January with Java and will hopefully be as good as you guys. If thats possible.

But it all works now. And im proud of all I have learned just by searching on the internet.
