how to delete rows in the "view" of JTable?

According with the MVC pattern, the view is responsable only and only for rendering the data from the model. The model store all the data and the processing issues of it. So a corect MVC implementation will delete the data from the model which will notify the view about state changed.

Keep in mind that you have (according to MVC pattern) one single model and virtualy a infinity of views associated to that model.

ok, then how exactly can delete the rows in runtime?

If you delete a row in a Table but not in the underlying model then you are NOT deleting the row but "hiding" it in in that particular view. That function would therefore be the resposibility of the view, not the model.

The easiest way to do this is to build some row filtering class that sits between the view (JTable) and the model (DefaultTableModel). It adds itself to the TableModel as a listener and allows the JTable to add itself to it as a listener. It then proxies the conversation between the two.

You should be able to find a way of masking off or not displaying certain rows in the Table.

"If you delete a row in a Table but not in the underlying model then you are NOT deleting the row but
                     "hiding" it in in that particular view. That function would therefore be the resposibility of the view,
                     not the model." - The VIEW according to MVC pattern, is responsable for displaying the data from the MODEL, and only for this. Also, the VIE is in direct relation with the CONTROLLER, which listen for any kind of input events. So "hiding" data on the view is a result of implementing a hiding algorithm into the MODEL. This is not a sollution to avoid delete of data contained by the table unless the programmer want's this kind of behaviour.

alen_ycc : I will write shortly to you a example of doing that.

Thanks Ovi, your code is excellent, thanks!
may i have your ICQ No.? my no. is 81119581,
