JTable中正在编辑的单元格的位置

Question

I want to get the coordinates (row index and column index) of a cell of JTable when key is released during editing that cell. I am trying to do it in this way:

@Override
public void keyReleased(KeyEvent released) {
    JTable tbl = (JTable)(released.getSource());
    if (tbl.getCellEditor() != null)
        System.out.println(tbl.getSelectedRow()+","+tbl.getSelectedColumn());
}

But this does not return position (row index and column index) of cell being edited. Please help.

Answer 1

when key is released during editing that cell.

Doesn't make sense. The editor has focus when a cell is being edited. Also the user could use the mouse to put the cell in editing mode.

If you want to know when a cell starts editing you can add a PropertyChangeListener to the JTable :

//
//  Implement the PropertyChangeListener interface
//
    @Override
    public void propertyChange(PropertyChangeEvent e)
    {
        //  A cell has started/stopped editing

        if ("tableCellEditor".equals(e.getPropertyName()))
        {
            if (table.isEditing())
                // code for editing started;
            else
                // code for editing stopped;
        }
    }

Then you just use the getSelected...() methods to get the row/column.
