URGENT JTable : deselect a cell at runtime

Hi,

I need to deselect a cell at runtime (by clicking on a JButton) in a JTable and I can't managed to do it with isCellEditable()...

Does anybody have any idea how to do it ??
please help,
Thanks a lot by advance.

I don't know of a simple way to deselect a single cell programmatically. As far as I know, you can only deselect whole rows and columns.

What you can do is fake it by using a TableCellRenderer that treats the cell in question as unselected and without focus, something like this:

Code:

---

table.setDefaultRenderer(Object.class, new DefaultTableCellRenderer() {
        public Component getTableCellRendererComponent (JTable table,
                            Object value,
                            boolean isSelected,
                            boolean hasFocus,
                            int row,
                            int column)
        { 
                // Use appropriate row & col values here
                if (row == 2 && column == 2) {
                        isSelected = false;
                        hasFocus = false;
                }
                return super.getTableCellRendererComponent(table,
                        value, isSelected, hasFocus, row, column);
                                                       
        }                               
});

---

Then you can ensure it won't be edited with isCellEditable().
