i want that info placed in a buffer so it can be sent to c++ program and the string parsed using the jni. i am not concerned with the latter part. just want to know how to get the text into a buffer and back out to another text area.
thanks

try this (some part may be of no use):
[code]
private boolean ALLOW_COLUMN_SELECTION= false;
private boolean ALLOW_ROW_SELECTION= true;

table.setSelectionMode
(ListSelectionModel.SINGLE_SELECTION);
if (ALLOW_ROW_SELECTION)
{
ListSelectionModel row =table.getSelectionModel();
row.addListSelectionListener(new ListSelectionListener()
{
public void valueChanged(ListSelectionEvent e)
{
//Ignore extra messages.
if (e.getValueIsAdjusting())
return;
lsm =(ListSelectionModel)e.getSource();
if (lsm.isSelectionEmpty())
{
output.setText("No rows are selected.");
output.setText("\n");
}
else
{
selectedRow = lsm.getMinSelectionIndex();
if (resultObjects!=null)
{

try
{
if (selectedRow<resultObjects.length)>
output.setText(SNReflection.print(resultObjects[selectedRow], false));
System.out.println("Row " + selectedRow
+ " is now selected.");
}
catch (Exception exc)
{
exc.printStackTrace();
System.out.print(exc);
output.setText("Unable to display object.");
}
}
else
output.setText("No data found");
}
}
});
}
else
{
table.setRowSelectionAllowed(false);
}
if (ALLOW_COLUMN_SELECTION)
{ // false by default
if (ALLOW_ROW_SELECTION)
{
//We allow both row and column selection, which
//implies that we *really* want to allow individual
//cell selection.
table.setCellSelectionEnabled(true);
}
table.setColumnSelectionAllowed(true);
ListSelectionModel colSM =
table.getColumnModel().getSelectionModel();
colSM.addListSelectionListener(new ListSelectionListener()
{
public void valueChanged(ListSelectionEvent e)
{
//Ignore extra messages.
if (e.getValueIsAdjusting())
return;
lsm = (ListSelectionModel)e.getSource();
if (lsm.isSelectionEmpty())
{
output.setText("No columns are selected.");
//output.append(SNReflection.print("No columns are selected."));

output.setText("\n");
}
else
{
int selectedCol = lsm.getMinSelectionIndex();
//output.setText("Column " + selectedCol +
//" is now selected.");
System.out.println("Column " + selectedCol +
" is now selected.");
output.setText("\n");
}
}
});
}
