Rudimentary question: Adding MouseListener to JTable rows

I am adding a MouseListener to the rows of a table in order to add Drag and Drop to the rows (with Apple's D & D API).This is as far as I've gotten:

for (int i = 0; i < table.getRowCount(); i++) {
row[ i ].addMouseListener( rowListener );
}
Which returns the following error:
"...Undefined variable: row
row.addMouseListener( rowListener );
^ "

I [i] think [/i] that what I am looking for is to define "row" using something like:
" row = table.grabAllTheRows "
then add the MouseListener to each row:
"row[ i ].addMouseListener( rowListener )".

If I am on the wrong track, please let me know.

yep..you need to define the type of row first and then provide it an object reference..but you can eliminate the row variable by using table.getRow(i) method or it's equivalent in the API.

table.getRow(i).addMouseListener(rowListener);

Hi gsatsan;

Thanks for the comment. I tried it and this code:

for (int i = 0; i < table.getRowCount(); i++) {
table.getRow(i).addMouseListener(rowListener);
}

returns this error message:
"...Method getRow(int) not found in class javax.swing.JTable.
table.getRow(i).addMouseListener(rowListener);"
^
How do I fix it?

Thanks in advance.

Hi,

getRow() won't help. You need it to be Component to add mouse listener. JTable doesn't have components which correspond to rows. Add MouseListener directly to table and use columnAtPoint() and rowAtPoint() to get column/row information.
