JTable cell Editing

Hi gurus,
I am new to the Java forum (I have C++ background) and I am a bit confused on a swing issue.
I need to open a JFrame window containing a JTable and have a specific cell open for editing.
I tried the following code in jbInit()

Code:

---

          jTableHighScores.editCellAt(newRank - 1, 2);
            jTableHighScores.getEditorComponent().requestFocus();

---

but the specified cell is not open for editing.
I have to move the mouse on it and doubleclick to open it. What do I miss?

Also I need to capture the <enter> when the user finishes editing with the cell and then do smthng with the new value. How do I go about it?

Thank you

You can edit the table cells in the following way :-

Code:

---

// Create table
    int rows = 10;
    int cols = 5;
    JTable table = new JTable(rows, cols);
   
    // Enable the ability to select a single cell
    table.setColumnSelectionAllowed(true);
    table.setRowSelectionAllowed(true);
   
    // Set the cell on the 2nd row, 4th column in edit mode
    int row = 1;
    int col = 3;
    boolean success = table.editCellAt(row, col);
    if (success) {
        // Select cell
        boolean toggle = false;
        boolean extend = false;
        table.changeSelection(row, col, toggle, extend);
    } else {
        // Cell could not be edited
    }

---

Then capture the 'enter' key event with the below code:

Code:

---

table.getModel().addTableModelListener(new MyTableModelListener(table));
   
    public class MyTableModelListener implements TableModelListener {
        JTable table;
   
        // It is necessary to keep the table since it is not possible
        // to determine the table from the event's source
        MyTableModelListener(JTable table) {
            this.table = table;
        }
   
        public void tableChanged(TableModelEvent e) {
            int firstRow = e.getFirstRow();
            int lastRow = e.getLastRow();
            int mColIndex = e.getColumn();
   
            switch (e.getType()) {
              case TableModelEvent.UPDATE:
                if (firstRow == TableModelEvent.HEADER_ROW) {
                    if (mColIndex == TableModelEvent.ALL_COLUMNS) {
                        // A column was added
                    } else {
                        // Column mColIndex in header changed
                    }
                } else {
                    // The rows in the range [firstRow, lastRow] changed
                    for (int r=firstRow; r<=lastRow; r++) {
                        // Row r was changed
   
                        if (mColIndex == TableModelEvent.ALL_COLUMNS) {
                            // All columns in the range of rows have changed
                        } else {
                            // Column mColIndex changed
                        }
                    }
                }
                break;
            }
        }
    }
