    text
    copied!<p>I try to use JTable but when I invoke setValueAt method data don't update in gui. I try to find the answer more then 5 hours but anything help me.</p> <p>I try to updateUI and fireTableDataChanged() but id doesn't help.</p> <p>I use AbstractTableModel and my constructor is JTable(MemoryTableModel). Look at my code of MemoryTableModel:</p> <p>What i`m doing wrong, or what I forget?</p> <p>(Sorry for my english, its not my native language)</p> <pre><code>public class MemoryTableModel extends AbstractTableModel { private static final long serialVersionUID = 1L; ArrayList&lt;ArrayList&lt;Object&gt;&gt; memoryCells; String[] columnNames = {"Offset", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "A", "B", "C", "D", "E", "F"}; public MemoryTableModel(byte[] data, int cells) { super(); memoryCells = new ArrayList&lt;ArrayList&lt;Object&gt;&gt;(); for (int i=0; i&lt; cells/16; i++) { ArrayList&lt;Object&gt; a = new ArrayList&lt;Object&gt;(); a.add(i); for (int j=0; j&lt;16; j++) { a.add(data[i*16+j]); } memoryCells.add(a); } } @Override public int getColumnCount() { return columnNames.length; } @Override public int getRowCount() { return memoryCells.size(); } public String getColumnName(int col){ return columnNames[col]; } @Override public Object getValueAt(int line, int column) { return memoryCells.get(line).get(column); } @Override public void setValueAt(Object cell, int row, int column) { memoryCells.get(row).set(column, cell); fireTableDataChanged(); } public boolean isCellEditable(int rowIndex, int columnIndex) { if (columnIndex == 0) return false; return true ; } </code></pre>
