I added message to my Dialog, the system says that "cannot find the specified file" Re: Delete Row in AbstractTableModel 13 Years Ago by JamesCherrill AbstractTableModel is an abstract class, you can't create an instance of it, nor does it define methods for removing rows. Maybe you are thinking of DefaultTableModel - which implements AbstractTableModel and has methods for adding & removing rows. See the API doc for details Re: AbstractTableModel 10 Years Ago by stultuske hate to tell you, but even the first line of the code you posted wouldn't compile. you need to end it with a ';', not a ','. also, this: `}catch(IOException evt){JOptionPane.showMessageDialog(null," Error ");}` even though not the worst, not far from it.

Re: Java - Adding data from to a JTable from an AbstractTableModel using Linked 13 Years Ago by ejosiah use a TableModel or convert your list to an Object[][] or convert your list to a vector Re: The problem with AbstractTableModel 14 Years Ago by Ezzaral Well, you didn't post the relevant part of your QueryTableModel class: [iCODE]tableModel.setQuery()[/iCODE], but it looks like your default row sorter isn't very happy about an empty data vector. I don't think you're handling an empty result set quite right in your model. Re: The problem with AbstractTableModel 14 Years Ago by LianaN Thank you. How could I handle an empty result set in a correct way? setQuery is as follows: [CODE] public void setQuery(String q) { cache = new Vector(); try { // Execute the query and store the result set and its metadata ResultSet rs = statement.executeQuery(q); ResultSetMetaData meta = (ResultSetMetaData) rs.… Re: The problem with AbstractTableModel 14 Years Ago by LianaN yes, you are right about the row sorter. If I run the program without a row sorter, then it works. However, if I use: [CODE]sorter = new TableRowSorter<QueryTableModel>(tableModel); tableAttributesFormTypes.setRowSorter(sorter);[/CODE] ...then it fails. But how could I improve my code? Re: The problem with AbstractTableModel 14 Years Ago by Ezzaral The DefaultRowSorter is blowing up when it tries to determine the column class in your model, because you are using the value of the first element to determine the class here[CODE] @Override public Class getColumnClass(int col) { return getValueAt(0, col).getClass(); }[/CODE]That's all fine and well when there is an element at index 0 … Re: The problem with AbstractTableModel 14 Years Ago by LianaN Oh, thank you very much!!! [ICODE]return cache.size()>0 ? getValueAt(0, col).getClass() : null;[/ICODE] helped to solve the problem!

It works! Re: Custom AbstractTableModel, Editor and Renderer 11 Years Ago by CoilFyzx I'm sorry but I have read those tutorials, and the are not so explixit so as to make me competent enough to solve this niche question. Re: Custom AbstractTableModel, Editor and Renderer 11 Years Ago by mKorbel - you have to override setValueAt with proper notifier - change current methods - nobody knows how Editor and Renderer is used in your code - whats wrong with code example from Oracle tutorial Re: Custom AbstractTableModel, Editor and Renderer 11 Years Ago by CoilFyzx Let me strip down my problem: I have created a custom TableModel for my table. I have also used JComboBox as the editor for a number of the table's columns. The trouble I am having is that when I select an option from the Combobox's dropdown list, it does not display in the cell; the cell remains blank. Why is this please?
