  1. POError when sorting rows in Jtable
    text
    copied!<p>I'm trying to set a <code>RowSorter</code> on my Jtable, I used the method <code>setAutoCreateRowSorter(Boolean b)</code> to sort the rows</p> <pre><code>table.setAutoCreateRowSorter(true); </code></pre> <p>But when I make the table as <code>rawSorted</code>, I get a strange error!</p> <p>The conflict is visible when I want to delete a line, I used <code>fireTableRowsDeleted()</code>.</p> <pre><code>int raw = table.getSelectedRow(); // the index of raw that i want to delete it System.out.println(raw); model.delte_raw(raw); // model is my table model public void delte_raw(int raw) { if (!ls.isEmpty()) { this.fireTableRowsDeleted(raw+1, raw); ls.remove(raw); } </code></pre> <p>I want to show you what result return the code as above in 2 cases:</p> <h2>Case 1:</h2> <p>When I make my table as not rawsorted:</p> <pre><code>table.setAutoCreateRowSorter(false); </code></pre> <p>when I delete a line, it all works successfully.</p> <h2>Case 2:</h2> <p>When I make my table as rawsorted:</p> <pre><code>table.setAutoCreateRowSorter(true); </code></pre> <p>when I delete a line, I get the error as below:</p> <pre><code>Exception in thread "AWT-EventQueue-0" java.lang.IndexOutOfBoundsException: Invalid range at javax.swing.DefaultRowSorter.checkAgainstModel(DefaultRowSorter.java:921) at javax.swing.DefaultRowSorter.rowsDeleted(DefaultRowSorter.java:878) at javax.swing.JTable.notifySorter(JTable.java:4277) at javax.swing.JTable.sortedTableChanged(JTable.java:4121) at javax.swing.JTable.tableChanged(JTable.java:4398) at javax.swing.table.AbstractTableModel.fireTableChanged(AbstractTableModel.java:296) at javax.swing.table.AbstractTableModel.fireTableRowsDeleted(AbstractTableModel.java:261) </code></pre> <p>I think that the error is in my defaultRowSorter, so I defined my specific <code>cellRenderer</code> as below:</p> <pre><code>// final TableCellRenderer r = table.getTableHeader().getDefaultRenderer(); //TableCellRenderer wrapper = new TableCellRenderer() { // private Icon ascendingIcon = new ImageIcon("images/e.png"); // private Icon descendingIcon = new ImageIcon("images/e.png"); // // @Override // public Component getTableCellRendererComponent(JTable table, // Object value, boolean isSelected, boolean hasFocus, // int row, int column) // { // Component comp = r.getTableCellRendererComponent(table, value, isSelected, // hasFocus, row, column); // if (comp instanceof JLabel) { // JLabel label = (JLabel) comp; // label.setIcon(getSortIcon(table, column)); // } // return comp; // } // // /** // * Implements the logic to choose the appropriate icon. // */ // private Icon getSortIcon(JTable table, int column) { // SortOrder sortOrder = getColumnSortOrder(table, column); // if (SortOrder.UNSORTED == sortOrder) { // return null; // } // return SortOrder.ASCENDING == sortOrder ? ascendingIcon : descendingIcon; // } // // private SortOrder getColumnSortOrder(JTable table, int column) { // if (table == null || table.getRowSorter() == null) { // return SortOrder.UNSORTED; // } // List&lt;? extends RowSorter.SortKey&gt; keys = table.getRowSorter().getSortKeys(); // if (keys.size() &gt; 0) { // RowSorter.SortKey key = keys.get(0); // if (key.getColumn() == table.convertColumnIndexToModel(column)) { // return key.getSortOrder(); // } // } // return SortOrder.UNSORTED; // } // //}; //table.getTableHeader().setDefaultRenderer(wrapper); </code></pre> <p>But again, the same error!</p> <p>Why do I get this error? I googled it a lot, but either I used the wrong keywords or there are no simple solutions on the internet.</p>
